Pre-Start Health & Safety Review (PHSR/PSR) Services

HITE Engineering provides Pre-Start Health And Safety Reviews. A Pre-Start Health & Safety Review is also known as a PSR, PHSR. The Ministry of Labour enacted legislation in Ontario under Section 7 of Regulation 851 for Industrial Establishments on Oct.7, 2000. Essentially, this was the Ministry of Labour requiring industry to engage the services of a professional engineer (or industrial hygienist) to review equipment or processes when any one of eight circumstances exist.


These 8 circumstances are paraphrased as follows:
