Specifies requirements for the design and construction of fixed and movable guards intended to afford protection from mechanical hazards at machinery.

This Standard specifies general requirements for the design and construction of guards both fixed and moving provided primarily to protect persons from mechanical hazards associated with machinery.Attention is drawn to the use of guards to minimize exposure to non-mechanical hazards.The requirements of this Standard are applicable if fixed and movable guards are used. The Standard does not cover those parts of guards which actuate interlocking devices. These are covered in AS 4024.1602.This Standard does not provide requirements for special systems relating specifically to mobility or to the ability to lift loads such as rollover protective structures (ROPS) and falling-object protective structures (FOPS).
