Pre-Start Health and Safety Review
Ensuring equipment and processes meet Ontario safety requirements before operation.
Service Overview
Pre-Start Health and Safety Reviews (PSRs) are required under Ontario OHSA Regulation 528/00 for specific equipment, processes, and workplace conditions. These reviews are intended to identify hazards and verify that appropriate safety measures are in place before machinery is put into operation. A PSHR is not limited to new installations. Modifications to existing equipment, changes in process, or integration of new systems can introduce new risks that require engineering review. Ensuring compliance at this stage helps prevent incidents and avoids regulatory issues later.
When a PSHR is Required
A PSHR may be required when a change introduces new or increased risk in the workplace.
This can include:
• Installation of new machinery or equipment
• Modifications to existing systems, including control systems
• Changes to process flow, layout, or production methods
• Introduction of automated or robotic systems
• Situations where safeguarding or hazard exposure is affected
Understanding when a PSHR is triggered is critical, as missed requirements can result in enforcement action or operational delays.
What We Do
C&R Engineered Solutions conducts detailed engineering evaluations to determine compliance and identify hazards.
Our work includes:
• Assessment of mechanical and electrical hazards
• Evaluation of safeguarding, interlocks, and control systems
• Review of equipment design and operation
• Identification of non-compliance with applicable standards
• Development of practical recommendations to address risks
Where required, we provide documentation and engineering reports to support compliance.
Why it Matters
Completing a PSHR ensures that equipment is safe to operate before production begins. It helps reduce the likelihood of incidents, protects workers, and ensures compliance with regulatory requirements. Addressing safety at this stage also minimizes costly modifications later and supports more efficient, predictable operations.
