CSA Z432 Fourth Edition Open for Public Review!

CSA just opened public review on CSA Z432, Safeguarding of Machinery, fourth edition. If you are a user, a builder of machinery, or an evaluator of machinery, this is your opportunity to see the draft of this important standard and to make comments to help the Technical Committee improve the standard on your behalf.

Note: The start of the public review period was briefly delayed, but is open as of 2022-03-11. The delay has extended the closing date to 2022-05-09.

CSA Z432, Safeguarding of Machinery, is the basic standard for the safety of machinery in Canada for most types of machinery. The first edition was published in 1994, with this fourth edition representing the continued refinement of the third edition.

Only Power Presses and Industrial Robots are covered separately in their own machinery safety standards. There are some other standards for man lifts and for cranes, however, these are outside of the OHS group for standards development within CSA.

What does Z432 cover?

If you build machines, modify, repair, or rebuild used machines for the Canadian market, or if you use machines in your business then this standard should be part of your working library. Regulators across Canada refer to CSA Z432 as the basis for compliance with Provincial and Territorial regulations. Engineers reviewing machines use CSA Z432 as the guide to safe machine design, referencing the standard in their reports and proposed modifications.

CSA Z432 provides guidance on important topics, like:

  • Risk Assessment
  • Risk reduction through the application of the Hierarchy of Controls
  • Guard design requirements
  • Safeguarding device application requirements, and
  • Instructions and information for use
  • Administrative control measures
  • Use of PPE
  • Training requirements
  • Safe use of industrial lasers and laser systems

What has been revised?

New in this edition are:

  • revised flow to make reading the document easier
  • extensively revised and expanded requirements for emergency stop functions and devices
  • shrouding of emergency stop devices to prevent inadvertent actuation
  • improved harmonization with ISO 13849-1 for functional safety
  • restoration of some figures related to the installation of pull-cord emergency stop devices that were in the 2004 edition but were removed in the 2016 edition
  • restoration of figures related to the types of guards and the installation requirements for safeguarding devices
  • much more!
