This Standard specifies requirements for helmets designed to protect the head from a blow by a heavy or sharp object, as well as adverse environmental conditions likely to be encountered in structural firefighting.

This Standard specifies performance criteria for faceshields, ear and neck protectors where these are fitted to the helmet. Other accessories are not covered by this Standard.

Those organizations responsible for other specialist functions, e.g. bush firefighting, are urged to use protective equipment specifically designed for these activities, e.g. Type 3 helmets specified in AS/NZS 1801.
