Why Flame Retardant Workwear Matters
In environments where workers are exposed to open flames, molten metal, welding sparks, or flammable chemicals, standard cotton workwear can ignite and continue burning, causing catastrophic injuries. Flame retardant workwear is specifically treated to resist ignition, self-extinguish when the flame source is removed, and protect the wearer from thermal hazards.
South African industries with flame retardant workwear requirements include mining operations, welding and hot work environments, petrochemical facilities, foundries, and electrical utilities. At Sheq Safety, our D59 Flame Retardant cotton range is manufactured in our SABS 434 accredited facility to provide reliable thermal protection for these demanding applications.
Flame Retardant Fabric Technology
Flame retardant workwear at Sheq Safety is produced using D59 100% cotton fabric treated with a specialised flame retardant finish. This treatment chemically bonds to the cotton fibres, creating a protective barrier that inhibits combustion. When exposed to flame, the fabric chars rather than burns, and the self-extinguishing properties activate as soon as the ignition source is removed.
Our D59 Flame Retardant fabric is produced at 320g/m² weight, providing substantial protection for high-risk environments. The flame retardant treatment is engineered for durability through repeated industrial washing cycles, though proper laundering protocols must be followed to maintain protective performance over the garment’s service life.
We also manufacture a combined Flame Retardant & Acid Resistant D59 fabric for environments where workers face both thermal and chemical hazards. This dual-treatment provides protection against flash fire hazards as well as incidental acid splashes.
Applicable Standards
SANS 1381-3 specifies requirements for protective clothing where there is a risk of molten aluminium splash. ISO 11612 sets the performance requirements for protective clothing against heat and flame, defining specific test methods for limited flame spread, convective heat, radiant heat, and molten metal splash.
For welding operations, ISO 11611 classifies protective clothing into Class 1 (lower hazard) and Class 2 (higher hazard) based on the intensity of welding operations. In mining environments, the Mine Health and Safety Act requires appropriate protective clothing for workers exposed to thermal hazards.
When specifying flame retardant workwear, always match the garment certification to the specific hazards present. A garment rated for limited flame spread may not provide adequate protection against molten metal splash unless specifically tested to that exposure condition.
Selection, Care, and Maintenance
Proper sizing is essential for flame retardant workwear. Garments should fit comfortably over underlayers without being excessively loose, as excess fabric can create pockets that may trap heat. All our flame retardant garments follow standard Sahara Workwear sizing from S through 6XL.
Maintenance directly affects the longevity of the flame retardant treatment. Garments must be laundered according to manufacturer instructions. Avoid bleach, chlorine-based detergents, fabric softeners, and industrial starch, as these chemicals can degrade the flame retardant properties. Inspect garments regularly for thinning fabric, holes, oil saturation, or chemical contamination. Any garment showing these signs should be removed from service immediately.
Keep detailed issue and inspection records for all flame retardant garments. Replace garments at intervals recommended by the manufacturer or sooner if visual inspection indicates degradation of the protective properties.
Conclusion
Flame retardant workwear is an essential control measure for workers exposed to thermal hazards. Understanding the fabric technology, selecting garments certified for your specific hazards, and implementing proper care and inspection programmes ensures that your flame retardant investment delivers reliable protection for your workforce.
