Safeguarding of machinery

Organization: CSA
Publication Date: 1 January 2023
Status: active

ICS Code (Safety of machinery): 13.110
scope:

General

This Standard applies to the protection of workers from the hazards arising from the use of mobile or stationary machinery. It provides the criteria to be observed and the description, selection, and application of guards and protective devices. Where a current CSA standard exists for a specific type of machinery (e.g., CSA B167, CAN/CSA-B354.2, CSA M424.1, CSA Z142, CSA Z248, and CAN/CSA-Z434), it is to be used in conjunction with this Standard to provide the most effective protection.

Note: This Standard is intended to be applied to newly manufactured and newly installed machinery as of the publication date of this Standard. The aim of this Standard is to promote a high standard of machinery safety during use.

This Standard describes a variety of risk reduction measures and provides guidance to determine which measure(s) to use. As a minimum it will, however, be necessary to consult specific legislation in applying the principles set down. Although reference is made to specific types of machines, specific recommendations are not given for every type of machine.

This Standard applies to rebuilt or redeployed machinery. The Standard can be used for enhancing the safety of existing machinery.

Exclusions

This Standard does not apply to portable hand tools.

Purpose

This Standard is intended for those who design, build, modify, install, use, operate, or maintain machinery, machinery guarding, or protective devices. It is also intended to be used by those concerned with information for use of the machinery and the development and implementation of instructions, and training and the effective implementation of administrative controls.

Interaction with other standards

Workplace safety is more than machinery safeguarding. Typically, machinery is installed in workplaces with other risks (e.g., movement of materials, cables, pipes, and hoses supplying energy, gases, and liquids, and workers on foot and operating vehicles). Other applicable machinery and workplace standards should therefore be reviewed.

Terminology

In this Standard, "shall" is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the Standard; "should" is used to express a recommendation or that which is advised but not required; and "may" is used to express an option or that which is permissible within the limits of the Standard.

Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.

Notes to tables and figures are considered part of the table or figure and may be written as requirements.

Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.

Measurements

The values given in SI units are the units of record for the purposes of this Standard. The values given in parentheses are for information and comparison only.
