Spiromatic 90U S-Mask First Breath

Examine jacket, trousers, and helmet for visible burn marks, melting, discoloration, or material brittleness. Test heat resistance at seams and high-stress areas. Verify compliance with EN469:2020 thermal barrier performance limits (radiant, convective, contact heat protection)

Inspect for cracks, tears, or delamination in the four-layer membrane structure. Test breathability by measuring water vapor transmission rate. Verify tape-sealed seams remain intact. Check for liquid water penetration resistance

Test mask positive pressure integrity with regulator safety valve activation. Verify audible chest alarm functions under noisy conditions. Inspect S-Mask for cracks and check plug-in regulator for blockages. Test ambient air hatch operation where applicable

Inspect ProBuddy helmet for cracks, impact damage, or material deformation. Test electrical insulation capacity (E2/E3). Verify chinstrap Nomex material condition and attachment security. Check polycarbonate visor for cloudiness, scratches, or coating loss

Inspect leather gloves for tears, brittleness, or water damage. Verify waterproof/breathable lining integrity. Check heat-resistant rubber boots for cracking, hardening, or sole separation. Confirm aramid lining protection against cuts and penetration
