Sets out the requirements for three types of protective helmets reflecting their intended use. It deals with construction of the helmet shell and helmet finish and includes methods of tests. Specific additional performance requirements are given for occupational protective helmets used in high temperature workplaces and for bushfire fighters' helmets based on industrial helmets.

This Standard specifies requirements for occupational protective helmets to protect wearer's heads from falling objects in building and construction, quarrying, shipbuilding, forestry and other occupations with similar hazards.These requirements include the construction and materials of the helmet shell and head harness, mechanical strength of the shell and finish of the helmet.Methods of test referred to in this Standard are set out in Appendices A to F inclusive.This Standard does not specify requirements for helmets for motor vehicle users, pedal cyclists, horse riders and structural firefighters. For such requirements see AS 1698, AS/NZS 2063, AS 2063.1 and 2063.3 and AS 4067 respectively.Guidance on the selection, use and maintenance of occupational protective helmets is given by AS 1800.
