ISO 11999-1:2024

This document specifies minimum design and performance requirements for personal protective equipment (PPE) to be used by firefighters whilst engaged in fighting fires occurring in structures, primarily but not solely to protect against exposure to flame and high thermal loads. The scope of this document does not include PPE for use in high risk fire exposures where, for example: —     protective clothing with reflective surface according to ISO 15538 might be more appropriate, —     where exposure to lower levels of heat or flame may be encountered by firefighters engaged in support activities where PPE according to ISO 11613 might be more appropriate, —     or for use in firefighting operations in high ambient temperature (for example bush, wildland or forest firefighting) where PPE according to ISO 16073 series might be more appropriate. Similarly, this document does not include PPE to protect against chemical and biological hazards, other than against short term and accidental exposure while engaged in firefighting and associated activities. This document provides an approach of a single minimum design and performance requirements for PPE, including optional requirements where identified, and for product markings and manufacturer’s instructions. Selection of an appropriate system of protective equipment is dependent upon an effective risk assessment which identifies the hazards to be faced, evaluates the likelihood of those hazards, and provides the means to reduce or eliminate these hazards (see ISO/TR 21808).
