What Face Shields Do?

Face Shield

We talk a lot about eye safety and eye protection when dealing with hazards like sparks, debris, or splashing chemicals, and focus on safety glasses and goggles as an important part of our personal protective equipment (PPE). This makes sense – our eyes are easily damaged, and becoming blinded from a work injury has significant repercussions for the injured employee and for the employer.

In our focus on protecting our eyes, though, let’s not lose sight of the fact that more than just our eyes need to be, and can be, protected. Many tasks require the use of face shields too. They provide additional protection for our eyes, and protect the rest of our face as well. With that said, there are some things that we need to understand about what face shields can and cannot do.

When properly used as part of a workplace injury prevention program, face shields provide additional protection against some impact hazards, or things flying into our faces. Do pay attention to the word ‘additional,’ though; when used on their own, OSHA does not consider face shields to be adequate  protection for impact hazards like flying fragments or objects, large chips, or particles.

To adequately protect an employee from those hazards, a face shield must be used with safety glasses or safety goggles. That’s right – 2 layers of protection. And if you think about it, it seems reasonable – the face shield can slow or even stop a flying hazard before it even reaches your glasses, which are within an inch of your eye. That’s a little close for comfort. A big part of why a face shield isn’t enough on its own, though, is that it doesn’t sit as close to your face or eyes, and so there is still potential for something to fly under the shield and injure your eyes. When combined with safety glasses or goggles, a face shield provides an important additional layer of protection not just for your eyes, but also protects the rest of your face from burns, cuts, or even exposures to toxic or caustic chemicals.

Selecting Face Shields

Like other PPE, we need to select the right face shield for the task at hand. To do so, we need to understand what options are available, what kind of protection is required, and how it will interact with other required PPE used for workplace injury prevention.

One of the most important decisions comes down to selecting the right type of window (also called a visor) on the face shield. Many are available in different types of plastic or plastic-like materials. These often provide excellent visibility for the worker, are usually lightweight (reducing the strain on the worker’s head and neck), and can even be ANSI rated for impact protection.

The materials don’t all function the same, though. Some of these materials are more scratch resistant than others. Some provide adequate protection against specific chemical exposures, whereas others may provide none, or worse, might interact with specific chemicals in dangerous ways. Keep that in mind when selecting face shields to protect against chemical splashes, and make sure to consult your safety data sheets for the chemicals that you use to make sure that your face shields are made of the right materials.

Plastic or plastic-like materials aren’t necessary, or even ideal, for all tasks though. Steel and nylon mesh windows are also available, protecting workers against impacts from larger objects. They won’t provide the same level of protection against dusts, fumes, and vapors, though, as they do not form a solid shield, allowing dusts and vapors to pass through the mesh. That same mesh design allows for even greater airflow for the worker, which can be particularly useful when working outside in the heat.

Other required PPE can also affect what types of face shields are appropriate. One common type is attaches to hard hats, allowing employees to  wear adequate head protection. When hard hats are not required, face shields are also available as adjustable headgear. Decisions on which type to use will depend on your PPE assessment, which makes it essential that a thorough analysis is performed so that employees have adequate PPE for workplace injury prevention, so that using face shields does not expose them to additional hazards.

What is Corona Virus

Now, the world is being horrendous with a disease caused by the corona virus.

Everyone is busy looking for masks, hand sanitizers and other protective devices in order to protect themselves from the virus.

Before this action, it better for us to find out about what is the corona virus.

Corona viruses are a family of viruses known for containing strains that cause potentially deadly diseases in mammals and birds. In humans they’re typically spread via airborne droplets of fluid produced by infected individuals. Some rare but notable strains, including Wuhan coronavirus (2019-nCoV), and those responsible for severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS), can cause death in humans.

First described in detail in the 1960s, the coronavirus gets its name from a distinctive corona or that projects from the envelope surrounding the particle. Encoding the virus’s make-up is the longest genome of any RNA-based virus – a single strand of nucleic acid roughly 26,000 to 32,000 bases long.

There are four known genuses in the family, named AlphacoronavirusBetacoronavirusGammacoronavirus, and Deltacoronavirus. The first two only infect mammals, including bats, pigs, cats, and humans. Gammacoronavirus mostly infects birds such as poultry, while Deltacoronavirus can infect both birds and mammals.

Coronaviruses are zoonotic, meaning they are transmitted between animals and people.  Detailed investigations found that SARS-CoV was transmitted from civet cats to humans and MERS-CoV from dromedary camels to humans. Several known coronaviruses are circulating in animals that have not yet infected humans.

Common signs of infection include respiratory symptoms, fever, cough, shortness of breath and breathing difficulties. In more severe cases, infection can cause pneumonia, severe acute respiratory syndrome, kidney failure and even death.

Standard recommendations to prevent infection spread include regular hand washing, covering mouth and nose when coughing and sneezing, thoroughly cooking meat and eggs. Avoid close contact with anyone showing symptoms of respiratory illness such as coughing and sneezing.

What are the symptoms of a coronavirus?

Unlike MERS and SARS, the Wuhan coronavirus is usually fairly mild. It can take longer for symptoms to develop. Symptoms may include:

  • A mild cough.
  • Shortness of breath.
  • A runny nose.
  • A sore throat.
  • A headache.
  • A fever.

So far, only 15 to 20% of cases have become severe. Those with weakened immune systems may develop more serious symptoms, like pneumonia or bronchitis. So far, only people 40 years old and older have developed the Wuhan coronavirus infection.

What causes a coronavirus?

Humans first get a coronavirus from contact with animals.  Then, it can spread from human to human. Health officials do not know what animal caused the Wuhan coronavirus. The Wuhan coronavirus can be spread when one human comes into contact with an infected person’s bodily fluids, such as droplets in a cough.  It might also be caused by touching something an infected person has touched and then touching your hand to your mouth, nose, or eyes.

How is a coronavirus diagnosed?

If you believe you may have a coronavirus, you should see your doctor immediately. Before just showing up to your doctor’s office, alert your doctor that you’re coming and why. This will allow the office to prepare and perhaps isolate patients to prevent the spread of infection. To diagnose you, your doctor will run tests to rule out other common infections.

 

Love Your Eyes

There are four things you can do to protect your eyes from injury:

  1. Know the eye safety dangers at your work.
  2. Eliminate hazards before starting work by using machine guards, work screens or other engineering controls.
  3. Use proper eye protection.
  4. Keep your safety eyewear in good condition and have it replaced if it becomes damaged.

Selection of protective eyewear appropriate for a given task should be made based on a hazard assessment of each activity. Types of eye protection include:

  • Non-prescription and prescription safety glasses — Although safety glasses may look like normal dress eyewear, they are designed to provide significantly more eye protection. They have lenses and frames that are much stronger than regular eyeglasses. Safety glasses must meet standards of the American National Standards Institute (ANSI). Look for the Z87 mark on the lens or frame. Safety glasses provide eye protection for general working conditions where there may be dust, chips or flying particles. Additional side protection can be provided by the use of side shields and wraparound-style safety glasses. Safety lenses are available in glass, plastic, polycarbonate and Trivex™ materials. While all four types must meet or exceed the minimum requirements for protecting your eyes, polycarbonate lenses provide the highest level of protection from impact.
  • Goggles — Goggles provide impact, dust and chemical splash protection. Like safety glasses, safety goggles are highly impact resistant. In addition, they provide a secure shield around the entire eye and protect against hazards coming from any direction. Goggles can be worn over prescription glasses and contact lenses to provide protection from flying objects and chemical splashes and in dusty environments.
  • Face shields and helmets — Full face shields are used to protect workers exposed to chemicals, heat, or bloodborne pathogens. Helmets are used for welding or working with molten materials. Face shields and helmets should not be used as the sole means of protective eyewear. They need to be used in conjunction with safety glasses or goggles. Wearing safety glasses or goggles under face shields also provides protection when the shield is lifted.
  • Special protection — Other types of protection, such as helmets or goggles with special filters to protect the eyes from optical radiation exposure, should be used for tasks such as welding or working with lasers.

One way to ensure that safety glasses provide adequate protection is to be sure they fit properly. Also, eye protection devices must be properly maintained. Scratched and dirty devices reduce vision, cause glare and may contribute to accidents.

Protective eyewear works best when you know how to use it properly. Combined with machine guards, screened or divided work stations, and other engineering controls, using the correct protective eyewear can help keep you safe from any type of eye hazard.

Personal Cleaning and Disposal of Contaminated Clothing

Chemical Agents: Facts About Personal Cleaning and Disposal of Contaminated Clothing

Some kinds of chemical accidents or attacks may cause you to come in contact with dangerous chemicals. Coming in contact with a dangerous chemical may make it necessary for you to remove and dispose of your clothing right away and then wash yourself. Removing your clothing and washing your body will reduce or remove the chemical so that it is no longer a hazard. This process is called decontamination.

People are decontaminated for two primary reasons:

  1. to prevent the chemical from being further absorbed by their body or from spreading on their body, and
  2. to prevent the chemical from spreading to other people, including medical personnel, who must handle or who might come in contact with the person who is contaminated with the chemical.

Most chemical agents can penetrate clothing and are absorbed rapidly through the skin. Therefore, the most important and most effective decontamination for any chemical exposure is decontamination done within the first minute or two after exposure.

How to know if you need to wash yourself and dispose of your clothing

In most cases, emergency coordinators will let you know if a dangerous chemical has been released and will tell you what to do.

In general, contact exposure to a chemical in its liquid or solid form may require you to remove your clothing and then thoroughly wash your exposed skin. Exposure to a chemical in its vapor (gas) form generally requires you only to remove your clothing and the source of the toxic vapor.

If you think you have been exposed to a chemical release, but you have not heard from emergency coordinators, you can follow the washing and clothing disposal advice in the next section.

What to do

Act quickly and follow the instructions of local emergency coordinators. Every situation can be different, so local emergency coordinators might have special instructions for you to follow. The three most important things to do if you think you may have been exposed to a dangerous chemical are to (1) quickly remove your clothing, (2) wash yourself, and (3) dispose of your clothing. Here’s how:

  • Removing your clothing:
    • Quickly take off clothing that has a chemical on it. Any clothing that has to be pulled over your head should be cut off instead of being pulled over your head.
    • If you are helping other people remove their clothing, try to avoid touching any contaminated areas of clothing, and remove the clothing as quickly as possible.
  • Washing yourself:
    • As quickly as possible, wash any chemicals from your skin with large amounts of soap and water. Washing with soap and water will help protect you from any chemicals on your body.
    • If your eyes are burning or your vision is blurred, rinse your eyes with plain water for 10 to 15 minutes. If you wear contacts, remove them and put them with the contaminated clothing. Do not put the contacts back in your eyes (even if they are not disposable contacts). If you wear eyeglasses, wash them with soap and water. You can put your eyeglasses back on after you wash them.
  • Disposing of your clothes:
    • After you have washed yourself, place your clothing inside a plastic bag. Avoid touching contaminated areas of the clothing. If you can’t avoid touching contaminated areas, or you aren’t sure where the contaminated areas are, wear rubber gloves or put the clothing in the bag using tongs, tool handles, sticks, or similar objects. Anything that touches the contaminated clothing should also be placed in the bag. If you wear contacts, put them in the plastic bag, too.
    • Seal the bag, and then seal that bag inside another plastic bag. Disposing of your clothing in this way will help protect you and other people from any chemicals that might be on your clothes.
    • When the local or state health department or emergency personnel arrive, tell them what you did with your clothes. The health department or emergency personnel will arrange for further disposal. Do not handle the plastic bags yourself.

After you have removed your clothing, washed yourself, and disposed of your clothing, you should dress in clothing that is not contaminated. Clothing that has been stored in drawers or closets is unlikely to be contaminated, so it would be a good choice for you to wear.

You should avoid coming in contact with other people who may have been exposed but who have not yet changed their clothes or washed. Move away from the area where the chemical was released when emergency coordinators tell you to do so.

What is Hydrofluoric Acid?

What is Hydrofluoric Acid?

Hydrofluoric acid (HF), which termed as ‘The Bone Seeker’, has been used in glass etching, rust removal, petroleum refining, tanning and dyeing since mass production in 1931. It has become an indispensable raw material for the semiconductor industry and an important catalyst in the petrochemical process. Depending on its concentration, exposure to HF can cause death.

Where hydrogen fluoride is found and how it is used

  • Hydrogen fluoride is used to make refrigerants, herbicides, pharmaceuticals, high-octane gasoline, aluminum, plastics, electrical components, and fluorescent light bulbs. Sixty percent of the hydrogen fluoride used in manufacturing is for processes to make refrigerants.
  • Hydrogen fluoride is also used for etching glass and metal.

How you could be exposed to hydrogen fluoride

  • In a natural disaster, you could be exposed to high levels of hydrogen fluoride when storage facilities or containers are damaged and the chemical is released. This release could occur at an industrial site or even a retail location.
  • You could be exposed to hydrogen fluoride if it is used as a chemical terrorism agent.
  • If you work in an occupation that uses hydrogen fluoride, you may be exposed to this chemical in the workplace.
  • You may be exposed to hydrogen fluoride as part of a hobby.

How hydrogen fluoride works

  • Hydrogen fluoride goes easily and quickly through the skin and into the tissues in the body. There it damages the cells and causes them to not work properly.
  • The seriousness of poisoning caused by hydrogen fluoride depends on the amount, route, and length of time of exposure, as well as the age and preexisting medical condition of the person exposed.
  • Breathing hydrogen fluoride can damage lung tissue and cause swelling and fluid accumulation in the lungs (pulmonary edema).
  • Skin contact with hydrogen fluoride may cause severe burns that develop after several hours and form skin ulcers.

What Harm Does Hydrofluoric Acid Cause to the Human Body?

HF is a weak acid but highly toxic and corrosive. The harm to the human body can be divided into the skin, respiratory tract, eye, and digestive tract. The main cause that contributes to a life-threatening situation is still skin exposure. There might be no obvious symptoms at the beginning, but if it is not treated in time, the black necrosis of the affected part must be amputated or even cause death

Human Centric Lighting

Say it a boon or curse, but due to the modern lifestyle, our indoor stay time has increased rapidly. As we spend 90% of our time indoors, we do not consume the adequate amount of sunlight which is paramount for the human body. The indoor light conditions do not deliver light nutrition that people need to stay healthy. A sunny outdoor day provides 100,000 lux and a cloudy day still provides 10,000 lux. Indoor light levels are not even half of that. This artificial light that we have in our indoor environment (offices, homes, etc.) can throw off our eternal clocks and cause issues with sleep. It can further lead to destructive health consequence i.e. poor circadian synchronization, problems with body clock similar to jet-lag, disturbance of hormonal system, and compromised mood and productivity. This lack of exposure to the sun’s spectrum disturbs the Human Circadian System which is fundamental to our physiology and controls much of our behaviour.

Human Circadian System

“This diagram depicts the typical circadian pattern of a person. Although circadian rhythms tend to be synchronized with cycles of light and dark, other factors such as ambient temperature, lack of sunlight, stress, etc. can influence the rhythm as well.”

The natural variations of sunlight help determine the timing of our internal clock called the circadian rhythm and tell our bodies when to sleep and when to be alert. If our sleep-wake cycle is deregulated, it can affect our immune system, memory, and behaviour. Our health is somewhere suffering in this disconnection between natural light and artificial light. Though we cannot cut short our indoor stay time, but by replacing the conventional lighting solutions with human-centric lighting we can surely make a big difference.

Benefits of Human Centric Lighting

Light affects our vision, body, and emotions. Human Centric Lighting enhances human performance, comfort, health, and well-being by balancing visual, emotional, and biological benefits of lighting for humans. It also improves alertness and concentration during learning by providing a better light environment. Lighting systems that give higher light intensities and colour temperature at the right time can help to improve the duration of sleep and quality of sleep and thus improve learning effects.

  • Maximizes the concentration and energy.
  • Improves work performance and productivity.
  • Increases employee motivation and commitment.
  • Assures health safety in the indoor environment.
  • Improves circadian rhythm and quality of sleep.
  • Biorhythm adjustments for night shift workers.
  • Increases emotional stability and lowers the rate of depression.

Human Centric Lighting should be implemented across various sectors to ensure the well-being and performance of people at a maximum rate.

  • Education Sector

Schools are an excellent location for tuneable white light features. It doesn’t matter if the person is an elementary scholar or a teacher, both can leverage the benefit from an optimized lighting environment in a direct or indirect way. Human Centric Lighting can be used to improve alertness during tests and concentration tasks. The teacher may switch on an intensive, cool white light during these activities, or a warm white dimmed light for relaxation and group talk.

  • Healthcare Sector

Healthcare environments (operation rooms, recovery rooms, intensive care rooms, etc.) are well suited to implement Human Centric Lighting. To improve the conditions for patients, nurses, and surgeons, HCL should be implemented because it dives the room in different lighting zones depending on the tasks. This results in less strain on the eyes, less fatigue, and improved quality.

  • Residential Sector

Incorporating HCL in residential areas can prevent mood fluctuations, depressions, and stabilizes the circadian rhythm. The emotional and physical well-being can be improved because of restful nights in better environments. The residents can feel more relaxed with fewer headaches and less tired eyes.

  • Offices Sector

Corporate areas are excellent places to implement Human Centric Lighting as it can bring energy and motivation to employees. For countries with little daylight, HCL solutions may reduce seasonal depressions and other emotional disorders. Workplace lighting, in addition to providing enough light to conduct work-related visual tasks, can also improve employees’ alertness, mood, cognition, sleep-wake pattern, and health.

It is important to understand how light can impact the occupants’ health, productivity, and overall potential. With the range of modern lights options available (LEDs, tuneable white lights, etc.), establishing a safe and healthy space is easier than ever. They are also energy-efficient and easy to control with advanced control systems. Human Centric Lighting promotes smart and connected lighting systems that can create endless possibilities with better user control.

LED solutions from Panasonic helps customers across all the sectors to achieve the right balance of lighting solutions. It has helped millions worldwide with the energy-efficient and cost-effective Human Centric Lighting solutions. It offers an amazing array of LED lights – panel lights, ceiling lights, spotlights, etc. and trusted by homeowners, large corporations, hospitals, hotels, institutions, administrations, etc. for their lighting requirements.

The Rules When You Use Scaffolding

Many types of construction projects use scaffolding, but how do you know when you need scafolding? And what indicators mean that need scaffolding as part of your project? There are many factors to consider when deciding if the job requires scaffolding.

1) What are the Rules?

In most cases, health and safety guidelines advise that if you have more than four people working at height, then a proper risk assessment needs to be carried out. The conclusion of such a risk assessment will usually be that the safest way to carry out the job is with scaffolding. A good scaffolder will erect a safe scaffold structure for buildings and structures of any shape, size and dimension to ensure a safe fit for all tradesmen who will be working on the structure.

As per the HSE website, those with duties under the regulations must ensure that:

    • All work at height is properly planned and organised
    • Those involved in work at height are competent
    • The risks from work at height are assessed, and appropriate work equipment is selected and used
    • The risks of working on or near fragile surfaces are properly managed
  • The equipment used for work at height is properly inspected and maintained

2) How Big is the Job?

Scaffolding can seem surplus to requirement for small ‘one-man’ jobs, so in these cases, many people use a safely-secured ladder. However, ladders can only be used for low-risk, short duration work, and sometimes a ladder doesn’t give you full access to the entire roof and so the job only gets partly done. It’s important to remember that scaffolding is not only designed to keep those working at height safe, but also those on the ground. If there is any risk of tools or materials falling from the roof, then scaffolding with an edge fitted around the platform is essential to retain a safe working environment for all your workforce.

3) How Long Will the Job Take?

Scaffolding is advised in cases where the project involves working at height for more than three days, and also where weather is looking temperamental. Cornwall is notorious for its sudden weather changes so it’s crucial to retain a safe working environment by installing a temporary roof or scaffolding structure to maintain optimum safety for your project.

4 ) The Activities Requires Scaffolding

Scaffolding for Home Improvements

When a homeowner or landlord decides that they want to extend their kitchen, convert their loft or replace their rundown roof, more often than not they will require scaffolding to be erected in order for the work to be completed.
Construction workers may need access tower to reach the roof, or work platforms to make their job more comfortable and to get the work completed a lot quicker.

Scaffolding for Painters and Decorators

Painters can be expected to work at substantial heights for their job which means that scaffolding is important for keeping them safe and providing a secure work platform. They need to be able to place their tools and equipment by them as they work and move around the site with ease and safe access to all areas of the building.

Scaffolding for Building Repairs

When maintenance work is being carried out on a building (typically this is the gutter or roof), there is an increased risk of injury due to the faults that are being repaired. This could be surfaces that are not stable, tiles that are loose and structures that are at risk of falling. Hence, scaffolding can help reduce these risks by providing a safe surface and area for work to be carried out.

Scaffolding for Window Cleaners

Cleaning windows of larger commercial buildings, such as office blocks, hotels and retail stores, will require more than a ladder. Windows can often be found as high as twenty storeys and puts window cleaners at risk of falling from a fatal height. Scaffolding is one way of ensuring their safety and enabling them to carry out their job with ease and comfort.

Scaffolding for Building Inspections

Building inspections include checking the credibility and safety of buildings and structures. This inspection requires safety equipment to be installed such as scaffolding since it often involves reviewing the infrastructure’s various parts that can be located hundreds of metres above the ground. Additionally, you have to remember that the scaffold installed should adhere to safety standards.

Working At Height

Working at height is one of the most dangerous workplace activities. It presents a variety of different hazards for workers that would not typically be found when working at ground level and it has an increased probability of death or permanent physical injury due to its very nature. Therefore, it is so important to ensure that a thorough risk assessment is conducted before any work at height is carried out and that all workers are trained so that they can work safely. Identifying the potential hazards that workers may face is the first step in protecting them.

Stability of work platform/roof

When working at height there will be a work platform of some sort involved and many times this may be the roof of a building or some scaffolding. As long as the scaffolding undergoes a comprehensive and regular inspections. This means using a reputable scaffolding hire company and scheduling weekly scaffold inspections.

When work is being completed on a roof, it is often because it needs repairing or replacing which means that the surface is likely to be fragile and not very sturdy or secure. Falling through or off a roof is a common accident on construction sites so you need to consider the use of specialised equipment such as roof ladders and supported crawling boards to reduce the risk.

Weather

Though weather itself is beyond our control and often unpredictable in the UK, it is necessary to be prepared for rain, snow, ice and any other extreme conditions that may present itself.

Rain and ice can create slippery surfaces, strong winds can dislodge materials and even workers themselves and heatwaves can cause heatstroke and dizziness putting workers at risk of collapsing and falling from a height.

Workers can adapt to these changing weather conditions by implementing the appropriate precautionary measures when needed. For example, in extreme heat they should keep themselves hydrated and in strong winds they should carry out initial checks of their equipment and materials to ensure it can withstand the conditions.

Distance of potential falls

It is necessary to be aware of the distance at which work is being carried out and how injury from a trip, slip or fall can be prevented or greatly reduced should an accident happen.Once assessed, you may find it appropriate to provide workers with PPE such as a fall arrest system to keep them safe and secure should they fall when working at height.

Objects falling from height

It isn’t just the workers carrying out the work at height who are at risk, but anyone in the vicinity working or passing by below is in danger. Materials or equipment that is being used at height has the potential to fall and strike someone below which can cause irreversible damage.

To prevent an accident such as this, ensure that workers understand how to stack and store items at height to avoid them from being knocked/falling over. The working platform may also require guardrails or toe boards to completely prevent objects from slipping over the edge and you may even need to set up restrictions on the ground below so that no one passes by the area.

Safety Tips for Working At Height

Some sure-fire safety tips to keep in mind when working at height:

  • Set up railings correctly and ensure that safety belts/harnesses are connected properly.
  • Check your equipment still functions effectively before using it at height as malfunctions from a distance can be fatal.
  • Use the correct equipment for the job – this means having the correct size and type of ladder and using crawl boards, lifts or scaffold when required.
  • Use ladders properly – many workers still use ladders wrong when working at height, remember that at least one hand or three limbs should always be on your ladder .
  • Understand your roofing regulations – these are often misunderstood by many workers, so it is best to brush up on them before working on roofs at height.
  • Signage – make sure that safety signs and posters are present and clearly visible to remind workers of the safety precautions they are required to take on the site.

How Far Do You Know?

The things you should know about your torque wrench

Torque wrenches are common place across a variety of industrial processes, commercial garages and even homes wherever there is a precision assembly process utilising threaded fasteners. Considering their widespread use however, there remains a number of things that people get wrong or simply don’t know.

Here Philip Brodey at Norbar Torque Tools highlights the top ten things to consider:

  • Storing your torque wrench

When a torque wrench is in regular use it does not need to be wound back. However, when storing a torque wrench for an extended period of time, users should always wind it down to the minimum scale setting and never to zero. A fully loaded torque wrench, left in storage for a long period, can cause a set in the spring, causing it to weaken over time. On the other end of the scale, by completely off-loading the spring, other components within the wrench may move fractionally relative to each other. When you reapply spring compression the orientation of these components can change, therefore affecting accuracy. All in all, it is better to leave a bit of compression in the spring while in storage.

  • For accurate results, one click is enough

Users often allow torque wrenches to click multiple times, without being aware of the additional torque being applied to the bolts. Operate your torque wrench in a smooth and steady manner and remember that one click is enough.

  • Using your wrench on an anticlockwise thread

Many torque wrenches will only indicate in the clockwise direction. Therefore, it is necessary for users to always check the wrench’s specification before using it on an anti-clockwise thread to ensure the tool is suitable and, prevent a loss of torque control. Examples of left-hand threads include the left-hand wheel nuts of certain vehicles and the left pedal of bicycles.

  • Converting between torque units

Converting torque units can be tricky but is a very precise process. To help users calculate units more easily, they can turn to Norbar’ s calculator app available on IOS and Android. Alternatively, the calculator is also available online at https://www.norbar.com/Home/Torque-Unit-Converter.

  • Adjusting your torque wrench

Equipment manufacturers will always provide the required torque for any given piece of equipment and so when adjusting your torque wrench, it is important to ensure that these levels are met. Remember to always adjust the wrench up the scale to the required torque figure to ensure accurate setting.

  • Using marked loading points for accurate results

Most torque wrenches are length dependent and feature a marked loading point on the handle but, many people don’t use it. For accurate results, most torque wrenches have to be operated with your hand centred over the marked load point. It is also essential that this load point is observed when it comes to calibrating the torque wrench.

  • Using torque wrenches for undoing

So long as users operate with caution and do not exceed the maximum torque, most torque wrenches can be used for undoing. However, if the bolt will not free within the maximum torque of the wrench, another tool should be used instead. By exceeding the maximum torque limit during a bolt loosening you can affect the wrench accuracy, causing problems for future use. If in any doubt, use another tool for loosening bolts.

  • Adding extensions to the torque wrench handle

Users should never put a pipe or any other kind of extension onto a torque wrench handle as doing so can seriously damage the tool and make it inaccurate, never mind the potential safety hazard.

  • Locking it in

It can be all too easy to accidentally adjust the settings of a wrench during use so, if your torque wrench is fitted with an adjustment lock, you should always apply it before operating the wrench in order to avoid any unintended changes.

Ready for Work

Image result for ready for work

Coming into work healthy and in the right mindset every day is just as important as being properly trained or having the right tool for the job. Many factors, both on and off the job, affect how well or poorly we do our jobs on any given day. Some of the factors we will cover are sickness, fatigue, medication, and stress.

Sickness– We all get sick from time to time. Some illnesses are minor and work can continue, but others we need to stay home to get better before coming to work. When you are sick you may not be able perform your duties as needed and this can put yourself or others at risk for an injury. Know when it is time to stay home due to an illness. During flu season especially, it is important that you do not come to work and infect others. Not only are you not able to work to your fullest ability you also affect others being able to work due to being infected with your illness.

Fatigue– Fatigue is a killer on jobsites all across the country. Many employees work over the normal 40 hours a week. Add on the demands of home life and there are many people who are probably too tired to safely perform their functions. Get at least six hours of sleep a night and eat a balanced diet to help combat the demands of a busy life. Drink caffeinated drinks or take a break and stretch when feeling tired on the job.

Medication– Many medications affect how we feel. When starting a new medication it is important to try it off the job to see how it affects you. Ask your doctor about all of the side effects. Make sure he or she understands the work you do as well as any other medications you take. Let a supervisor know if you are not feeling well due to a medication. If you feel comfortable telling a coworker about what medication you are taking, let him or her know so they can keep an eye on you.

Stress– There is good stress as well as bad stress. We are more familiar with the bad stress. Stress from work demands, home demands, family problems, health problems, etc. affect us every day. A combination of high expectations for productivity and limited resources to complete work often leads to high stress levels on the job. It is important to be able to handle stress in a constructive way. Exercising or taking time to enjoy hobbies is a good way to relieve stress. Recognize when you are stressed and step away from the situation to take time to relax.

Summary
Whether it is sickness, fatigue, medication, or stress affecting you in a negative manner at work it is important to speak up and address the problem. When “simple fixes” are not enough to correct a health related issue it is important to let a supervisor know and cease the work task. Address the problem at its source to ensure you can continue to work productively and safely.
