The reference standard in Canada for the Machinery Safety is the Technical Norm Z432-04.
This Standard is intended to be applied to newly manufactured and newly installed machinery. The aim of this Standard is to promote a high standard of machinery safety during use.
It specifies requirements for the design, manufacture (including remanufacture and rebuilding), installation, maintenance, operation, and safeguarding of industrial equipment to prevent injuries and accidents and enhance the safety of personnel who operate, assemble, and maintain machinery.
However, a lot has changed in the last 15 years when it comes to machine safety: technology, hazard combinations, solutions, and even the scope of health and safety. These changes have prompted a comprehensive updating of the Canadian machine safeguarding standards reflecting in a new standard.
CSA Z432-16, Safeguarding of Machinery reflects “the tremendous amount of time and effort put into revising machine guarding standards. New sections and thoroughly updated material will provide workplaces with valuable information for protecting workers who operate or maintain machinery.
Like the previous edition, CSA Z432-16 sets out requirements for the design, manufacture, installation, maintenance, operation, and safeguarding of industrial equipment. The new standard applies to newly manufactured, rebuilt and redeployed machinery, but may also be used to set upgrade targets for existing machinery.
Focus on New Technology. There’s more information on the classification of lasers and related safeguarding and training measures, plus expanded information on sensitive protective equipment (safety light curtains, safety beams, laser scanners, pressure-sensitive protective devices – mats, edges, and bumpers – as well as vision-based protective devices.
More Information on Identifying Hazards. “Annex A was amended and includes discussion on many types of hazards – chemical, biological, physical, energy and explosion. All are covered in the new standard.
A Revised Section on Risk Assessment. Specifically, Clause 5 does a thorough job of walking users through that process. What it would look like, what to consider, who should be involved, and how to move through it.
Alignment with International/Other standards on Machine Design and Performance. The document harmonizes with ISO standards so the information is seamless.
With changes come challenges
Z432-16 is going to be valuable to anybody who’s looking at machine safeguarding, It will help workplaces comply with their legislative requirements to protect workers.
For example, the professional engineer who carries out your next pre-start health and safety review for new equipment will base his findings on the new standard. You won’t be able to understand and follow those recommendations if you are not familiar with the new standard.
Moving machine parts have the potential to cause severe injuries in the workplace and a significant percentage of injuries in the workplace can be attributed to machine-related incidents each year. Machine safeguarding measures are essential to protecting the workers who come into contact with machines as part of their job duties. Any machine that may cause injury must be safeguarded. With Z432-16, additional precautions have been set into place to ensure that this takes place.
