Pre-Start Health and Safety Reviews (PSR) for Industrial Machinery
What is a Pre-Start Health and Safety Review?
A Pre-Start Health and Safety Review (PSR) is a safety assessment required under Ontario Regulation 851 when new or modified equipment is introduced into a workplace.
The review confirms that machinery and processes meet regulatory requirements before being put into service or modified for continued operation.
When a PSR May
Be Required
A PHSR may be required when:
• New machinery or automated equipment is installed
• Existing equipment is significantly modified
• Warehouse racking or storage systems are installed
• Cranes, hoists, or lifting devices are added
• Flammable liquids or combustible dust hazards exist
• A process presents ignition or explosion risk
Who We Work With
We work with manufacturers, machine builders, integrators, and facilities installing or modifying industrial equipment.
This includes projects involving new equipment installations, system upgrades, and modifications to existing machinery or processes.
Our work commonly supports material handling systems, racking and storage systems, lifting devices, and automated equipment where compliance with Ontario Regulation 851 is required.
We work with both new builds and existing operations where equipment is being introduced, changed, or brought into compliance.
PSR Process
1
Design Review
Review of equipment drawings, layouts, and safety systems prior to construction or installation, with a focus on identifying compliance requirements, potential safety risks, and required safeguarding before equipment is built or installed.
2
Preliminary Review
Inspection of equipment at the builder’s facility prior to shipment to verify that safety systems, guarding, and controls are in place, and to identify any compliance issues before the equipment is delivered and installed.
3
Final PSR
Final on-site review of installed equipment to verify that safety systems, guarding, and controls are in place and that the equipment meets Ontario Regulation 851 requirements before being put into service or returned to operation.
Why Straight In Solution Ltd.
Pre-Start Health and Safety Reviews are not just a regulatory requirement—they are a critical step in avoiding delays, redesign, and compliance issues once equipment is installed.
We focus on identifying risks early, at the design and planning stage, where issues can be resolved efficiently rather than corrected after installation.
Reviews are conducted by a licensed Professional Engineer (P.Eng.) with experience in industrial machinery, safety systems, and Ontario regulatory requirements.
This approach helps reduce the risk of Ministry of Labour orders, prevents costly rework, and supports a smoother path to production.
We work alongside your project team to keep compliance aligned with your schedule.
About the Engineer
Pre-Start Health and Safety Reviews are conducted by a licensed Professional Engineer (P.Eng.) with experience in industrial machinery, safety systems, and regulatory compliance under Ontario Regulation 851.
Work includes reviewing equipment designs, inspecting machinery at the builder stage, and assessing installed systems prior to operation across a range of industrial applications.
The focus is on identifying compliance issues early, communicating clearly with project teams, and providing practical recommendations that can be implemented without unnecessary delay.
Reviews are carried out independently, with attention to both regulatory requirements and real-world operating conditions.
