Kappler Frontline 500 Encapsulating Suit

NFPA 1990 (1991) Certified Apparel For Chemical Flash-Fire Protection.

Certified to NFPA 1990 (1991), Frontline® 500 offers proven three-way protection – broad chemical holdout, plus flame resistance and radiant heat protection for the additional hazards encountered in a chemical flash-fire. NFPA certification includes base plus Optional Flash Fire and Liquified Gas requirements. Like many Kappler garments, this is a ‘multi-use, single exposure’ suit. Frontline 500 provides excellent holdout for the ASTM F1001 battery and many additional chemicals.

To ensure optimal radiant heat protection, Kappler’s focus on user survivability included Pyroman Thermal Manikin testing in addition to the NFPA 1990 (1991) Chemical Flash Fire Option. Pyroman results for Frontline 500 indicated 0% body burn – a huge confidence factor when facing a chemical flash situation.
