Hazard Definition

The National Fire Protection Association (NFPA) defined a flash fire as “A fire that spreads by means of a flame front rapidly through a diffuse fuel, such as dust, gas, or the vapors of an ignitable liquid, without the production of damaging pressure.” Among others, this type of hazard is present in oil and gas and chemical manufacturing settings, as well as manufacturing environments where combustible dust can accumulate. Because the rapidly-moving flame front quickly consumes the diffuse fuel, flash fires are also very brief in duration – typically three seconds or less in any single location where a worker may be standing


Protection from Hazard

Because the flash fire is over quickly, we can protect workers from fatal and catastrophic burn injures with a single layer of secondary personal protective apparel – that is, by wearing flame resistant (FR) clothing. FR clothing will not ignite and continue to burn when the flash fire is over, insulating you from the hazard and dramatically reducing or eliminating burn injury. This is why FR clothing and PPE are now industry requirements. 


Proper Use

NFPA 2113 2018 edition offers guidance on the selection, care and use of flame resistant garments. New language added to the standard in the 2018 edition includes details on the selection criteria for flame resistant garments. Also, 2113 also now includes a recommendation that flame resistant or non-melting undergarments shall be used; this recommendation is considered a “best practice” in the industry.


FR Clothing Retirement and Disposal:

When FR Clothing shows sings such as Frayed Cuffs, Frayed Collar, Stained with Flammable Substance that cannot be removed, Unrepairable rips or holes, please DO NOT use this garment and contact your FR clothing manufacturer for instructions on safely dispose of the garment.

When taking your measurements, use a cloth tape measure, not a metal one. Measurements should be taken over standard undergarments. If you plan to wear clothing beneath your garments, order one size larger, to accommodate the extra garments.


Donning the coverall

While you may not think too hard about how you put on your clothing in the morning, putting on a protective coverall correctly is instrumental to the performance of the garment. Once the appropriate coverall has been chosen, a contamination-free changing room should be made available away from the workplace for workers to get dressed. Any objects that could obstruct work should be removed from pockets and left in a secure environment. Begin by sitting on a chair and removing your footwear. Then, carefully put your feet into the leg of the coverall one by one, before putting on and securely lacing your safety shoes or boots. At this point you should put on the correct gloves for the application. If you are using two sets of gloves, put the first set on now. Standing up, pull the suit up to your waist and place your arms into the sleeves. Before zipping up the suit, put on any goggles, masks etc and ensure they are fitted correctly, are comfortable and there are no gaps. Pull the hood up over your head and zip the coverall to the very top, pushing the zip down to lock. If you are wearing a second set of gloves put these on over the first pair of gloves, covering the wrist and sleeves of the coverall. It is recommended that all gaps and joins should be sealed with adhesive tape, including the ends of the gloves and around the face where the hood meets the facemask. A colleague should be present to check that the suit is donned correctly and that all gaps are sealed.

Doffing the coverall

Unless great care is taken in the removal and disposal of single-use protective garments, there is a risk of cross contamination from the surface of the garment to the wearer’s skin or hair or to other employees and family. The protective suit should be removed in a contamination-free space. Before taking off the protective clothing, it is advisable to clean the gloves and boots in order to prevent dust being thrown up. Masks and zip covers should be wiped clean too. Any protective items removed, such as adhesive tape, should be immediately disposed of in a chemical waste container provided for this purpose. With the protective gloves still on, the wearer should begin rolling the hood back, taking care not to let the outside of the coverall touch the head. Unzip the coverall and begin rolling that outwards, rolling it down over your shoulders. Place both hands behind your back and pull down each arm until completely removed. Sit down and remove each shoe then roll the coveralls down (ensuring the contaminated side is not touched or comes into contact with clothing) over your knees until completely removed. Finally discard the suit in the bag provided and remove your gloves.

When discarding the protective suit, it is important to hold it by the non-contaminated inner surface in order to prevent contact with the hazardous substance. The process of removing the suit results in contamination of the workplace, so this area must be cleaned as well. Leaving the danger zone whilst still contaminated poses a risk not only to the wearer of the protective suit, but also to others who are not involved in the procedure.

Selection and Use
With so many different coveralls on the market, how do you know which one is right for you? Every selection should begin with a risk analysis to determine the type of risk (chemicals, non-hazardous liquids, radiation etc), the length of exposure and level of protection required to protect against both elements. The more detailed the risk analysis, the easier it is to decide which protective suit is to be used. 

When you select protective garments, the key issues to be taken into account are:


•    Barrier protection (penetration and permeation)
•    Resistance (garment robustness)
•    Quality (of the garment material, zipper, seams, comfort, size and fit)
•    Convenience (garments should be user friendly)
•    Environmental compatibility (disposal should be safe and cost-effective)
•    Cost (although it is not recommended to make a decision based solely on price)

•    Tests and utilization (once a garment has been analyzed and it meets the necessary requirements an in-use test under real working conditions should be performed)

Care & Cleaning Recommendations
"Flame Resistant" ("FR") 100% cotton and Cotton Poly blended garments are made from fabrics treated with a durable flame retardant finish.


These garments can be laundered at temperatures normal to cottons. With the exception of FR denim, they can also be dry cleaned. Do not dry clean 100% cotton denim as the indigo dye system will fade and bleed into the solvent.


Flame resistant garments should be removed immediately and replaced with clean FR apparel if they become fouled with flammable materials.


Flame resistant apparel should be washed using soft water (less than 4.0 grains). Hard water adversely affects cleaning, resulting in increased detergent usage. Hard water contains mineral salts that can form insoluble deposits on the surface of fabrics. Sufficient buildup can negate the flame resistant characteristics of the garment, and may serve as fuel if garments are exposed to an ignition source.


These garments should not be worn where contact with strong oxidizers (e.g., >10% sodium hypochlorite, NaOCl) or reducing agents (e.g., sodium hydrosulfite, NaS2O4) is a consideration.


  • It is important that formulas are developed using detergents and wash temperatures (up to 165ºF) adequate to thoroughly clean all contaminants from garments.

  • Use non-ionic formulas. Do not use natural soaps (anionic or tallow soap) or silicate supplemented detergents. Soft water is recommended. Hard water precipitates soaps. It also contains calcium and magnesium salts. These products can build up on the fiber surfaces, coating the fabric and masking FR properties.

  • Chlorine bleach (sodium hypochlorite) and hydrogen peroxide (oxygen bleach), whether separate or contained in detergents, must be avoided. Repeated exposure to bleach can destroy the FR polymer and make the garments nonprotective.

  • Starch, fabric softeners, and other laundry additives can coat the fiber and mask the FR performance or serve as fuel in case of garment ignition. Therefore their use is not recommended. Garments should be soured to a pH between 5.5 and 6.5.

  • If garments are heavily soiled with particulate or abrasive soils, a flush at the beginning of the cycle will help reduce abrasion in the wash wheel. Wash formulas and load sizes should be set up to minimize redeposition and fabric abrasion.

  • Extract by methods typically used for regular 100% cotton garments.

  • Condition at a stack setting of 165°F so fabric temperature measured in the basket does not exceed 280°F. Normal shrinkage of 5 % to 6% can be expected. As with any 100% cotton fabric, excessive shrinkage may occur if overdried.

  • If desired, garments may be pressed using normal cotton pressing techniques.



  • Use any typical home laundry detergent. Powdered home wash detergents containing sodium perborate and other "color safe" bleach alternatives will not affect the flame resistance of the garments.

  • Do not use chlorine bleach, liquid nonchlorine bleach or detergents that contain hydrogen peroxide. These include but are not limited to liquid Tide with Bleach®, liquid Clorox II®, and liquid Vivid®.

  • It is important that all potentially flammable soils and other contaminants are completely removed from garments during the wash process. This may require the use of stain removal products, such as Shout®, Spray 'n Wash®, or Zout®; or presoaking garments prior to washing. The use of hot water can often make detergents more effective in soil removal. If all contaminants cannot be removed in home care, you should obtain professional help in getting your FR garments clean.

  • The use of conditioned or soft water can help improve removal of contaminants from garments. Hard water precipitates soaps and can result in the build-up of calcium and magnesium salts. These can serve as fuel in the event they are exposed to a source of ignition.

  • Starch, fabric softeners, and other laundry additives are not recommended because they can coat fibers and mask FR performance, or serve as fuel in case of garment ignition.

  • Do not over dry garments. If desired, you may press with an iron on the normal cotton setting.

  • We recommend you turn garments inside out to help reduce streaking that can occur due to abrasion in the washer.


Either perchloroethylene or petroleum solvent can be used. With petroleum, it is necessary to ensure that all solvent has been completely dried from the garments. Do not dry clean indigo dyed FR denim.


Minor repairs that do not affect the integrity of the garment may be made with like materials by either heat sealing or sewing on patches or darning small holes.


IML recommends to store your FR garment in a clean place and away from any chemical or liquid. Always check your garment before wearing to make sure there are no holes or frays,


IML recommends to inspect your garment before wearing to check for holes or tears, Consider replacing or repairing garment if holes/tears found, contact IML for instruction on how to repair or get a new garment.


IML recommends not to mark your garment on any labels to make sure all safety and care instruction is readable when needed, if needed please mark on the garment itself or on the pocket lining.
