This document specifies minimum requirements and test methods for the performance of three types (see 4.3) of footwear for use by firefighters for fire suppression, general-purpose rescue, fire rescue and hazardous materials emergencies. It also specifies requirements for footwear for firefighters equipped with customized insocks and customized footwear for firefighters. This document is intended to be used in conjunction with EN ISO 20345:2022. This document does not cover the property of high visibility because of interaction with the clothing (e.g. trousers cover the footwear and vice versa) and work area conditions (e.g. dirt, mud). Special risks are covered by complementary job-related standards (e.g. electrically insulating footwear, protection against chain saw injuries, protection against molten metal splash).
