Pre-Start Health and Safety Reviews

HITE Engineering provides Pre-Start Health And Safety Review Services in Ontario. A Pre-Start Health & Safety Review is also known as a PSR or 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 industries in Ontario to engage the services of a professional engineer (or industrial hygienist) to review equipment or processes when any one of eight circumstances exist to ensure health and safety in construction.

8 Scenarios Where Pre-Start Health & Safety Reviews are Required in Ontario

What is the Purpose of a Pre-Start Health & Safety Review?

There are many instances in health and safety assessments of equipment which are presently in an unsafe operating condition. The standards of workplace health and safety are increasing every year. This health and safety process is a means to improve the safety of new or modified equipment, to enhance the visibility of these standards, and to educate. The goal is to apply these standards to existing equipment to bring the whole standard of health and safety in construction up to enhanced levels.”

The objective of a Pre-Start Health & Safety Review (PHSR) and health and safety companies is to provide an in-depth examination of an apparatus, structure or process to identify any potential instances of non-compliance with the applicable provisions of the Industrial Establishments Regulation. A PHSR and environmental health and safety services serves the purpose of ensuring that any such hazards are removed or controlled before the item under review is used. A health and safety assessment can be conducted prior to first use or in support of an effort to bring used/modified equipment up to present day standards.

HITE Engineering is capable of performing workplace safety reviews of all eight triggers of PSR's in house.

What is the Process of a PSR?

      • Data Collection

        • Collection of documentation and information relevant to the equipment/process under review. (e.g. Specifications, operation manuals, schematics, SDS documents, health and safety risk assessments, etc.)
      • Review of Information

        • Assessment of the collected data in preparation for evaluation. Identification of any instances of non-compliance with referenced standards.
      • Site Visit

        • On-site inspection of the apparatus or process (if required) to confirm and identify all instances of non-compliance if any exist.
      • Evaluation & Report

        • Development of a Report of Findings outlining any items of non-compliance discovered and recommendations for remediation. Signed and sealed by a licensed Professional Engineer.


Typically, an engineer must conduct a PSR. Additionally, a PSR for Table Item 8 (hazardous biological or chemical agents) may be conducted by a person with specialized, special expertise, or professional knowledge or qualifications.

The Pre-Startup Safety Review (PSSR) is one of the fundamental instruments for managing change. In order to make sure that potential hazards have been adequately addressed, a PSSR consists of a checklist of items that must be thoroughly verified before a process begins or is restarted.

When a building, piece of machinery, or process is built, added to, or installed in the workplace, a Pre-Start Health & Safety Review (PSR) is necessary.
