When sourcing fire fighter gloves, compliance with international safety standards is non-negotiable. You must ensure the products meet NFPA 1971 (Standard on Protective Ensembles for Structural Fire Fighting) for the North American market or EN 659 for the European market. These certifications guarantee that the gloves have passed rigorous testing for flame resistance, heat penetration, and liquid integrity. Always request valid test reports from third-party laboratories like UL, SEI, or Intertek to verify these claims.
