WORKSafe® Flame Resistant (FR) Workwear
Where there are flammable materials being handled,processed, stored or in anyway present in the workplace hazards such as flash fires and explosions may occur due to accidental ignition of these materials. In various industries such as petrochemical and oil drilling, workers are exposed to risks of fire accidents which may cause severe or even fatal burns. If a flash fire does occur, wearing WORKSafe® FR Workwear would prevent fatal burn injuries by creating a fire resistant barrier which retards the flames and is self-extinguishing, thereby minimizing burn injuries.
All WORKSafe® FR Workwear are made of only quality FR fabrics and key accessories that are tested to EN ISO 11612 standards. In addition, only nickel-free buttons are used in WORKSafe® FR clothing, together with shorter stitches, double-stitching at all seams and bar-tacking at stress areas for enhanced durability.
When selecting FR Workwear, you should look for:
• Excellent fabric integrity – it should not melt and should provide the user with a barrier or insulating layer against exposure to flame
• Antistatic properties – the fabric should not act as anignition source via static electricity
• Global safety standards e.g. NFPA 2112:2012, EN ISO 11612:2008 – both the fabric and full garment should be properly tested
• Flame resistant key accessories e.g. threads, zippers, reflective strips, pocket linings
– Fit and mobility – FR Workwear should allow for maximum body movement and dissipation of thermal heat in event of flash fire
– Softness and weight – FR Workwear should be soft and lightweight
– Highly breathable – FR Workwear should be highly breathable and designed to help wearers feel cool and dry
Difference between Flame Resistant and Flame Retardant Materials:
Flame Resistant: Aramid fibers (aromatic polyamides) that are naturally flame resistant without any chemical treatment or process. These fibers have slower flaming combustion and self-extinguish when exposed to a flame of short duration during testing. Flame resistant materials do not melt, drip, burn nor support combustion in air. Its properties cannot be altered through cleaning and it’s generally strongly abrasion resistant.
Flame Retardant: Fibers that have undergone a chemical treatment so that the material is rendered flame resistant. The flame retardancy of the fibers deteriorate over time due to repeated washing and laundering.
The Flame Resistant Materials we use:
Nomex® III A: A meta-aramid fiber manufactured by DuPont™. It has a blend of 93% NOMEX®, 5% Kevlar®, and 2% P140 (static dissipative fiber). NOMEX® III A, as a fabric, has been tested to NFPA 2112 and NFPA 70E HRC 1 arc rating (USA) as well as EN ISO 11612 (Europe) standards.
There’s only one DuPont™ Nomex® brand fiber. That’s why for over 30 years, industrial workers and the people who protect them have demanded a genuine product. Fires are unpredictable and even a split-second can make all the difference. DuPont™ Nomex® brand fabrics and garments are subjected to rigorous testing in a variety of conditions by DuPont™ scientists and engineers who know and support the latest OSHA and NFPA standards; who constantly innovate, finding new ways to help safeguard your workers from fire and electric arc hazards; who are always working to offer solutions that help make protective gear stronger, more durable and safer. Nomex® brand fibers possess inherent flame resistant qualities that can’t be washed out or worn away, so it lasts. Nomex® brand garments are lightweight and comfortable for every worker. Clothe your crews with the name that means superior protection: DuPont™ Nomex®*.

The Flame Retardant Materials we use:
Pyrovatex®: A durable flame retardant product for cellulosic fibers. Pyrovatex®* is a treated fabric that offers the best overall fire protection available for cotton, as proven by comprehensive testing according to international flame retardant standards. Treated fabrics barely shrink when
exposed to heat and fires, thereby ensuring that the skin is not exposed to hazardous conditions. Treated cotton, unlike synthetics, will not melt in the presence of heat from fires. Treated fabrics also offer excellent thermal protection where heat is an added danger.
Key characteristics of Pyrovatex®:
• Outstanding durability to wash and wear, which assures long life of the clothing.
• Finishes have negligible influence on fabric coloration and therefore preserve flexibility to meet specific color demands.
• Treated fabrics have good compatibility with other treatments, permitting the creation of multifunctional garments.

Usage and Care of WORKSafe® FR Workwear:
• For a correct fit, try garment on before washing or wearing.
• Wash garments separately from other garments.
• Machine wash with hot water and heavy duty detergent (60°C/140°F).
• Tumble dry low (71°C/160°F).
• Do not bleach and avoid detergents containing bleach.
• Do not line-dry in direct sunlight.
• Wash your new workwear before wearing and after each subsequent wearing to thoroughly remove potentially flammable fabric processing aides/finishes, greases, oily soil and other flammable contaminants.
• Always wear 100% natural fiber undergarments with all flame resistant garments.
• Anti-static garments should be used in conjunction with proper grounding procedures for maximum protection against the threat of spark. Do not remove garments when in a hazardous environment.
