Part 22 Safeguards

Section 322 Wire mesh

Wire mesh can be used to create protective enclosures. Such enclosures may for example, restrain materials, prevent worker limbs from extending beyond work platforms or into moving machinery, or prevent loose materials from falling into underground shaft openings.

The thickness of the wire determines its strength and although the term “diameter” is used, a wire that is not round may be used but must be at least 1.63 millimetres (1/16 inch) thick across its thinnest dimension. The spaces of the wire mesh must be sufficiently small to prevent a 40 millimetre (1 9/16 inches) diameter object from passing through the openings with minimal effort.
