Tom Vardon

Tom is a robot safety auditor, risk assessor, and safety-system designer with 50 years of experience across industry, including electrical design, CAD drafting, IT, commissioning, industrial controls, and robot safety. He has focused on robot safety for 25 years and completed more than 500 machine and robotic risk assessments. His work has included automotive and other manufacturing applications across North America.

His work includes robot and machine risk assessments, functional safety engineering, safety PLC and electrical-circuit reviews, project support, and verification and validation. Support can begin at concept or design review and continue through commissioning or reassessment of equipment in service.

His approach starts with the tasks, people, hazards, and operating conditions. He then connects required risk reduction to the design, testing, and records needed to show how the system performs. Each engagement is scoped to the project and information made available.

Ontario PSHSR support can include evaluation and documentation assistance for the reviewing engineer. Compel does not provide the final letter stamped by a professional engineer.
Engineering approach

Begin with the hazard. Finish with evidence.

A safety claim should be connected to an identified hazard, a defined requirement, a suitable design, and a test that can show whether the requirement was met.

01 / DEFINE

Assess the application

Establish tasks, people, hazards, operating conditions, and relevant failures before selecting protective measures.

02 / SPECIFY

Make the response explicit

Define what must be detected, the required response, its timing, and the conditions for restarting.

03 / DEMONSTRATE

Test the claim

Connect analysis and measurements to acceptance criteria. Record limitations and unresolved assumptions.
