This International Standard specifies general requirements for the design, construction and selection of protective devices intended to protect persons from mechanical hazards. This International Standard specifies additional hazards that may influence the design and construction of guards. This International Standard applies primarily to guards on machines built after publication of this standard. The requirements apply to the use of fixed and movable protective devices. This International Standard does not cover interlocking devices. These are covered in ISO 14119. This International Standard does not contain requirements for special protective systems specifically designed for mobility such as ROPS (rollover protective structures), FOPS (falling-object protective structures) and TOPS (tip over protective structures) or the ability to lift loads.
