Machine Guarding in Ontario – The Basics

Machine guarding in Ontario differs from machine guarding anywhere else in North America.  The Ontario Ministry of Labor (MOL) has regulations and enforcement concerning machine guarding in Ontario.

Altering or repairing electrical equipment in Ontario, Canada, could be an electrical installation (work) by definition in the OESC (Ontario Electrical Safety Code) and may require a field evaluation/special inspection. ESA (Electrical Safety Authority) enforces the OESC. ESA mandates that a machine that requires a field evaluation must be locked out and de-energized until an organization such as CSA, Intertek, or ESA perform the field evaluation. The field evaluation is mandatory to comply with Ontario’s laws if a machine has had electrical modifications performed, such as installing an E-Stop button or adding anti-restart protection.

The Pre-Start Health and Safety Review (PSR) is specific to Ontario. It is required by the Occupational Health and Safety Act that industrial machinery or equipment has Pre-Start Health and Safety Review.  A licensed professional engineer must carry out this PSR.  Ferndale Safety can help you find a licensed professional engineer in Ontario.  We have partnered with a network of engineers in Ontario that can do PSRs regardless of whether you’re in Toronto, Ottawa, or Thunder Bay.

Since October 2000, a PSR has been required by law in Ontario under Section 7 of Regulation 851 of the Occupational Health and Safety Act (S.7 of O.Reg. 851). When installing any of the following protective elements on an apparatus, you must have a PSR performed by an Ontario professional engineer:

1. Safeguarding devices that signal the apparatus to stop. Including but not limited to safety light curtains and screens, area scanning safeguarding systems, radio frequency systems, capacitance safeguarding systems, safety mat systems, two-hand control systems, two-hand tripping systems, and single or multiple beam systems.
2. Barrier guards that use interlocking mechanical or electrical safeguarding devices. An Ontario-licensed electrical contractor must perform any work on an electrical apparatus as per Ontario regulation 570/05.

An exception to this is:

Work done within an industrial establishment or on a farm by an owner, operator, or employee; or Maintenance, service, or repair of electrical equipment that plugs into an electrical source. This work must not include extending or altering the equipment or installing, extending, altering, or repairing any electrical wiring connected to the equipment.
