Application of Non-FR Emblems & Embroidery
Whether it is appropriate to attach non‐FR embroidery and emblems to flame resistant protective garments is always a difficult question to address. The only comment of the consensus standards writing organizations, such as NFPA and ASTM, is that nothing on an article of clothing may increase the extent of wearer injury in case of garment ignition. ASTM in Standard F‐1506, Standard Performance Specification for Flame Resistant Textile Materials for Wearing Apparel for Use by Electrical Workers Exposed to Momentary Electric Arc and Related Thermal Hazards states in an appendix item that, "Logos, name tags, and other heraldry should be limited in number and surface area".
No OSHA or military standards address this area. SFI, the race driver's association, has not addressed this issue. However, identification and personalization are clearly safety issues in themselves that must be addressed by end users.
In the final analysis, the end user of the garment must weigh the benefits of identification and personalization against the potential risk from using non‐flame resistant materials. Common sense in the size, placement, and number of these materials is the best solution.
How flame-resistant fabrics work
Flame-resistant (FR) fabrics and garments are intended to resist ignition, prevent the spread of flames away from the immediate area of high heat impingement, and to self-extinguish almost immediately upon removal of the ignition source.
Normal work apparel will ignite and continue to burn if exposed to an ignition source such as flame or electric arc. Everyday fabrics will continue to burn until they are extinguished or all flammable material is consumed.
