What is fire resistant clothing?

To begin, let’s define flame-resistant clothing. Flame-resistant clothing may seem like a safe bet based solely on the name, but this is not the case. What you’re saying, is that correct?

The term “flame-resistant clothing,” or “FR clothing” for short, is used to describe garments that are constructed with the express purpose of shielding their wearers from the potentially harmful effects of direct contact with flames or high temperatures.

It guarantees that the garment will not catch fire easily and, in the event that it does catch fire, will not keep burning once the ignition source is removed. When exposed to open flame from a flash fire, arc flash, combustible dust explosion, or any other fire source, even flame-resistant clothing can and will catch fire. Bear in mind that FR clothing is NOT fireproof. The “magic” of FR occurs once the flame source has been turned off. Wearing flame-resistant clothing to work will not increase the severity of a burn.

If we want to get more technical about this definition, we can examine the specific ways in which flame-resistant clothing protects its wearer. These garments are flame-resistant and self-extinguish in the event of a fire. If you are wearing this type of clothing and you are exposed to a brief, sporadic flame, the flames will go out on their own. This feature reduces the wearer’s vulnerability to burn injuries and, in many cases, buys the wearer precious extra seconds to leave a dangerous situation.

If the wearer is caught in a flash fire, an electric arc, or any other sudden thermal problem that could cause injury, these features will work together to greatly increase the wearer’s chances of evading harm and surviving. Wearing clothing that can withstand fire can mean the difference between serious burns and a miraculous escape.

What should I wear under my flame-resistant clothing?

If flame-resistant clothing is meant to keep you safe from fire and high temperatures, is there anything else you can do to increase its effectiveness? Is there anything else you can tell me that might affect the effectiveness of this clothing?

Your safety and the performance of your flame-resistant clothing are both affected by the clothing you wear underneath it. Always be sure to wear non-melting clothing underneath these clothes at all times.

This caution is warranted for two main reasons. The first is that you are effectively doubling your FR safety with this measure. You will still be safe from the elements if your first layer of outerwear is compromised by fire or other external factors. When you add in the fact that there is an air gap between the layers, you have a formidable barrier against the elements.

Working in a high-heat environment is another case where you’ll want to wear bottoms that won’t melt. Your undergarments may still melt or overheat despite the protective outer layer. These undergarments can catch fire and cause serious burns if the temperature or humidity is high enough.

Isn’t All FR Clothing the Same?

No. There are many options for FR clothing, so it’s important to do some research before settling on a strategy. Clothing can and will vary greatly in terms of weight, protection level, and even cut. The fit, feel, and appearance of a FR garment are significantly influenced by the type of FR fabric used to make it.

Many times, the “cheapest” or “most cost-effective” solutions end up costing more than originally anticipated. Many businesses, in a rush to comply with the new OSHA regulations, have turned to NFPA 2112-certified clothing as their FR solution. However, a garment’s NFPA 2112 certification and lower upfront cost are no guarantee of its durability. A purchase that seems insignificant at the time can become a major burden later on.

What is FR clothing made of?

There are two types of flame-resistant fabrics used to make clothing: those with FR properties built in and those that must be treated to achieve the same effect. Fabrics that are inherently flame resistant (FR) are designed to be permanently flame resistant (FR) because the FR properties are incorporated into the fabric’s molecular structure. Even after repeated washings and wearings, the FR properties of the garment will remain intact.

Chemical applications are used to create FR properties in treated fabrics. With continued use, the FR properties of the garment will degrade and offer less and less protection. A treated FR fabric will lose its effectiveness over time due to normal wear and tear, abrasion, sun exposure, and laundering. When you consider that chemical FR treatments applied to fabrics like cotton often present significant environmental concerns about the effluents of such processes, it’s easy to see why the cost of ownership of these garments won’t look as good in the long run as it does in the short run.

Natural fibres like cotton that have been treated with FR chemicals have been known to shrink when used to make clothing. This can significantly reduce the garment’s wearability and durability. Although it may seem prudent to spend less on a garment today, if it only lasts for one season, you would have been better off investing in a more long-lasting and durable FR solution.

Which FR fabric is used in a garment may also affect the level of protection it provides. Initially, a treated FR fabric’s body burn percentage rating may be 35%; however, as the FR properties degrade, the rating may rise. The percentage of body burn that an inherently FR fabric produces will remain constant for the lifetime of the garment. It is important to look into the percentages when comparing different FR solutions, as a FR garment or even FR fabrics only need a 50% body burn rating to be NFPA 2112 certified. There are plenty of fabrics and garments that can withstand a 50% body burn, but how much of a difference is there between a 35% body burn and a 15% body burn? The marginal increase or decrease in percentage could be decisive.

Work is being done in the oil and gas industry. Furthermore, they are frequently exposed to hazardous conditions because of the nature of their work. Working in the hot sun in dry conditions for long periods of time can teach you quickly and painfully the value of water conservation. To stay cool and dry while working, employees should wear clothing that “wicks,” or draws sweat away from the skin.

The materials used to create fireproof garments vary. There is a wide range of options to consider, and none of them are without flaws. There are advantages and disadvantages to each. It is in the best interest of each business to select the material that is optimal for their specific circumstances. What ensures an employee’s safety in one workplace may not be sufficient in another.

Mixtures of materials are commonly used to create flame-resistant clothing. Typically, synthetics are used for this purpose. They’re slow to catch fire and built in safety features make them self-extinguishing.

The following are some examples of fibres commonly used to make FR clothing due to their inherent flame-resistance.

Current industry standards and customer preferences favour modacrylic, which is why it is so widely used. Multiple types of flame-resistant fabrics can be made from a blend that includes these fibres. Fabrics made from these varying blends of fibres are extremely resilient and can withstand a wide range of regulations.

Another fibre with natural fire resistance is Nomex. Nomex doesn’t require any additional FR fabric to make FR clothing, unlike modacrylic fibres. However, it need not stand alone. You can also use it in tandem with Kevlar or other materials. As a long-standing favourite in many settings, Nomex® is the most well-known inherently FR fabric currently available. However, as time has passed, the market has seen many alternatives that provide the same inherent protection without the typical stiffness and poor moisture management that are the main complaints about it in the field.

The Kevlar fibres are not only highly flame-resistant, but also very strong and with a wide range of other useful properties. Kevlar can be used to make a wide variety of products, including clothing that is resistant to flames. In order to create FR clothing, Kevlar is typically combined with Nomex.

There will be benefits and drawbacks to using every type of flame-resistant material. As an example, Kevlar is a very durable material, but its high cost deters many people from using it. However, all items of flame-resistant clothing have the same goal of safeguarding the wearer from potentially dangerous heat.

Is cotton flame-resistant?

It’s a common misconception that garments constructed entirely of cotton offer protection against fire, electric arcs, and high temperatures. This, however, is not the case, as even garments made entirely of cotton can catch fire. It will catch fire easily when exposed to heat and won’t put out by itself like flame-resistant clothing does.

Fabrics made of cotton are not as likely to melt or burn as those made of nylon or polyester, but they are just as flammable if not more so. According to these findings, it is clear that cotton garments cannot replace flame-resistant gear in any circumstance.

What are the benefits of flame-resistant clothing?

There is no denying the usefulness of flame-resistant and flame-retardant clothing. The risk of injury to workers is greatly reduced as a result of their use in high-risk environments. It is true that no item of flame-resistant clothing can completely eliminate the possibility of injury, but the risk is much lower when the worker is wearing such a garment than when they are wearing regular clothing.

However, the promise of fire-resistant clothing is not that it will be completely safe from fire. They are built to prevent fires and succeed in this role in all but the most hazardous circumstances. Yet, flame-resistant clothing’s greatest strength lies in its ability to contain blazes. In the unlikely event that the clothing does catch fire, it will typically self-extinguish in a short amount of time.

The wearer is less likely to sustain burns and has more time to escape the dangerous environment thanks to the clothing’s self-extinguishing properties. There’s a better chance the fire won’t spread and the worker won’t get hurt.

Work can be done in otherwise dangerous conditions, such as high temperatures and open flames, because of flame-resistant clothing.

How should flame-resistant clothing fit?

In general, FR clothing that is too big to wear comfortably will provide less protection than clothing that is too tight. If you wear a looser-fitting garment, more air can circulate between it and your skin, protecting you from the effects of any heat or flames you may encounter. You’ll be right up against the flames if you don’t loosen up those flame-resistant clothes. It is safer to allow this air cushion between your skin and the fabric than to rely solely on the clothing as a protective layer.

But don’t take that as a green light to stock up on the baggy stuff you can find. This may seem like a good plan at first, but it could end badly. Keep in mind that loose clothing is more likely to get caught on obstacles and make you immobile or rip, exposing you to environmental dangers.

To solve the problem, look for a compromise. There should be no excess fabric around your body or loose folds on your garments. A looser fit is preferable, but not so much so that it flaps around or gets caught on things.

Keep in mind that the first few times you wash your new flame-resistant clothing, it will shrink just like any other piece of clothing. Considering this, you may want to purchase a size or two up from what you normally wear to allow for the garment to shrink to its final, desired size.

When does my flame-resistant clothing need to be replaced?

There will be times when your FR clothing is damaged, but easily fixable; however, there will also be times when the garments are damaged beyond repair. There’s nothing to be done but to replace them after this happens.

Some of the most telling signs that it’s time to replace your flame-retardant clothing are as follows:

• Large rips or holes prevent the garment from being repaired properly.
• The fabric is too tattered and threadbare to offer sufficient defence against the elements.
• There is no way to clean the flammable substance out of the clothing.
• Bleach has been used on the garment.
• There are holes, frays, or openings in the collar, cuffs, or seams.
• It’s crucial to act quickly if your flame-resistant clothing shows any of these symptoms. Make a hasty purchase of a replacement.

It’s possible that you’re pondering, “The condition of this garment is unimpaired. I should probably get a replacement, but I’m going to hold off for a while longer, maybe a week or a month.” Although this way of thinking makes sense, it poses serious risks and should be avoided. There’s no way to predict when misfortune will strike. If your FR gear is damaged on the one day you really need it to keep you safe, you could be in trouble.

Who washes FR clothing?

Employers who expect workers to launder their own work clothes at home have an obligation to provide their staff with instruction in proper laundering techniques and to conduct regular inspections of the uniforms to detect any signs of wear. If an organisation is unable to provide these factors, it is their responsibility to clean the FR and arc-rated clothing.

In reality, doing laundry at home can be dangerous. Laundering of FR and arc-rated clothing is the responsibility of the employer unless they are willing or able to meet the requirements for home laundering.

How to wash and dry FR clothing?

The good news is that cleaning most FR clothing items is straightforward. These garments can be laundered with your regular washing machine and dryer, and whatever laundry detergent you prefer. To clean FR clothing, you need make only minor adjustments to your standard washing and drying routine.

One thing to keep in mind is that you shouldn’t wash your FR clothes in chlorine bleach. Fabric softeners should be avoided as a general rule. Finally, it’s recommended that you wash these garments individually for the best results. If your FR clothing is particularly dirty and in need of a thorough cleaning, follow the care label’s instructions and wash it in the hottest water possible.

As most FR garments contain some cotton, they are likely to shrink after their first few washes. Avoiding the dryer can help keep your clothes from shrinking if you hang them up to dry instead of putting them in there.

It is recommended that you check the labels of your FR clothing if you have any other questions or concerns about their specific characteristics. In spite of the fact that every manufacturer is unique, you can usually find more specific washing instructions in the manufacturer’s manual. In any case, the aforementioned suggestions should give you sufficient background to get going.

How many times can you wash FR clothing?

Most flame-resistant clothing is constructed to be highly durable and robust. Therefore, it will probably be fine after a few washes in the washing machine. You can safely wash your FR clothing as often as it requires it. You can wash your FR clothing as often as you like, so long as you don’t use the items we mentioned earlier (like fabric softener or bleach) that aren’t recommended.

Choosing the best supplier for your company’s FR clothing and fabrics can be challenging due to the abundance of available options. Keep in mind that your needs are not necessarily the needs of everyone in your industry, but that any FR is better than no FR at all. There is a wide variety of FR clothing and fabrics available; pick the one that makes you feel the safest, most comfortable, and most secure. Learn the truth about FR, bust any myths you may have heard, and then you can make an informed decision about the best course of action to take.

Conclusion

Specifically made to withstand the heat and flames of an open flame or high temperatures, flame-resistant clothing is a necessity for those who work in dangerous environments. To lessen the likelihood of burn injuries and give the wearer more time to escape a potentially dangerous situation, it is flame-resistant and self-extinguishes if exposed to fire. However, it is not fireproof and will ignite in the presence of an open flame, such as that of a flash fire, an arc flash, an explosion of combustible dust, or any other ignition source. Wearing something that won’t melt underneath these garments will maximise their effectiveness.

You should always wear FR clothing because it increases your FR protection and protects you from the elements. Clothes can be made from either naturally flame-resistant (FR) materials or materials that must be treated to achieve the same result as naturally FR materials. Since the type of FR fabric used to make a garment greatly affects its fit, feel, and appearance, it is important to do some research before settling on a strategy. Clothing that meets the standards of NFPA 2112 can be an economical option, but this does not ensure that it will last. Although treated fabrics can initially retain their FR properties through chemical applications, these characteristics gradually degrade with time and repeated washings, rubbings, and exposures to the elements.

When used to make clothing, natural fibres like cotton that have been treated with FR chemicals have been known to shrink, reducing the wearability and durability of the garment. The level of protection offered by an article of clothing may also depend on the type of FR fabric used to make it. Since a garment or even FR fabrics only need a 50% body burn rating to be certified by NFPA 2112, it is important to look into the percentages when comparing different FR solutions. Clothing that “wicks,” or draws sweat away from the skin, is ideal for workers in the oil and gas industry. There are pros and cons to wearing each type of fireproof clothing because of the different materials used to make them.

Fabrics like modacrylic, Nomex, and Kevlar, among others, are used to make flame-resistant clothing, but synthetics are the most common. The most well-known naturally flame-resistant fabric is Modacrylic, while Nomex has long been a favourite in many settings. Kevlar fibres are used to make a variety of products, including flame-resistant clothing, because they are not only highly flame-resistant but also very strong and with a wide range of other useful properties. Each flame-resistant material has advantages and disadvantages, so it’s vital that businesses pick the one that works best for them. In case of a fire, does cotton hold up?

It is a common misconception that flame-resistant clothing can be used to protect the wearer from fire, electric arcs, and extreme heat. Cotton is highly combustible and should never be worn in place of flame-resistant clothing or equipment. One of the greatest benefits of flame-resistant clothing is that it can put out small fires and buy you some precious time. Allowing air to cushion the fabric is preferable to relying solely on the garment itself as a safety measure. When it comes to fire safety, how loose or tight should clothing be?

As opposed to tight clothing, looser items of clothing offer less defence against the elements. The most critical information is that flame-resistant clothing must be replaced if it is damaged beyond repair, and that prompt action is required if any of the aforementioned warning signs appear on the garment. Buying a size or two larger than your usual size is recommended so that the garment can shrink to the correct fit after washing. Lastly, it’s important to remember that the first few times you wash the garment, it will shrink just like any other piece of clothing. If your company requires employees to clean their uniforms at home, you should train them in how to do so properly and inspect uniforms on a regular basis for signs of wear.

If a company doesn’t have access to those things, it’s on them to clean the FR and arc-rated gear. It is the duty of the employer to provide the necessary provisions for home laundry, as this activity can be hazardous to the employee. If you hang your clothes to dry instead of putting them in the dryer, you can prevent them from shrinking. If you have any other questions or concerns, please refer to the labels on your FR clothing. Just how many times can you safely launder FR gear?

After a few washes in the washing machine, most flame-resistant clothing should be good as new. It can be difficult to find a reliable source for flame-resistant (FR) clothing and fabrics for your business, but obtaining some FR is always preferable to none at all. Get the facts about FR, debunk the rumours, and make a calculated choice.

Frequently Asked Questions

How do you know if clothes are fire-resistant?

A surefire way to know how to can tell if clothes are fire-resistant or not is to check for an arc rating. FR clothing must label the arc rating of that particular piece of clothing in order to sell it. The higher the number, the more protection it offers.

 

What is a fire-resistant fabric made of?

Fabrics with a tight weave – wool, modacrylic, 100 per cent polyester and those that are flame-retardant treated are good choices. Heavy, tight weave fabrics will burn more slowly than loose weave, light fabrics of the same material. The surface texture of the fabric also affects flammability.

 

What is fire-resistant vs flame-resistant clothing?

Flame-Resistant clothing is made from material that is inherently resistant to flames and embers. Meaning that the threads and fibres will naturally self-extinguish. Flame-Retardant clothing, on the other hand, is made from materials that have been chemically treated to achieve the same self-extinguishing properties.

 

What are fire-resistant fabrics used for?

Using fire or flame retardant fabrics helps in two ways: They burn slowly / self-extinguish, and so limit the spread of fire. They help reduce the heat build-up and so prevent rapid fire development (also known as flashovers)

 

How long does flame-resistant clothing last?

Cotton-nylon blends will generally remain flame-resistant for anywhere from 18 months to 30 months if they are washed and worn once a week. The most long-term FR fabric solution for uniforms is a synthetic blend, which can last from 24 months to four years, depending on how it is cared for.
