Engineering Reviews


In Ontario, it is required by the Occupational Health and Safety Act that Industrial Machinery or Equipment have a Pre-Start Health and Safety Review carried out by a Licensed Professional Engineer.

What is a PSHSR?

A Pre-Start Health and Safety Review is an assessment by a Professional Engineer of any Industrial apparatus, protective element, process, or structure, to ensure compliance with applicable standards as laid out in Section 7 of Regulation 851, R.R.O. 1990 of the Occupational Health and Safety Act. The assessment involves an inspection of equipment followed with a written report indicating measures required to bring the equipment into compliance with the applicable standards. The purpose of a PSHSR is to identify and eliminate workplace hazards through proper safeguarding of the equipment. To date, PARCS Ltd. has performed well over 1000 PSHSR for a diverse list of customers over the past 7 years.
