What are the SCBA straps made out of?

• A. Kevlar
• B. Nylon
• C. Polyester
• D. Leather

Answer: (A)

SCBA straps must stay secure under heavy loads and during exposure to heat and rough handling. Kevlar, an aramid fiber, provides exceptional tensile strength and abrasion resistance while withstanding high temperatures without melting. This combination keeps the cylinder harness reliably in place in tough firefighting conditions. Nylon and polyester are strong webbing materials, but they can soften or melt when exposed to heat or flame. Leather can degrade with heat and moisture and doesn’t offer the same abrasion resistance or durability under flexing. So Kevlar is the best fit for SCBA straps because it maintains integrity and strength when conditions get harsh.
