Repair Criteria and Authorised Repair Procedures
topic
NFPA 1851 specifies authorised repair types for structural firefighting clothing including restitching seams with FR thread, replacing retroreflective trim with certified equivalent materials, patching outer shell fabric with like materials using appropriate seam construction, and replacing hardware with certified equivalents, with repairs to moisture barriers and thermal liners generally restricted to manufacturer or certified repair facilities where appropriate materials and repair validation can be ensured.
Role
Extends the service life of structural firefighting clothing through authorised repairs that restore performance without compromising the composite system integrity, while preventing the use of improper repair materials or techniques that would create false confidence in restored protection while leaving performance gaps, with repair certification requirements ensuring that repaired clothing meets the same performance standards as original equipment.
