Ontario Health and Safety Consultants for Workplaces

An Electrical Safety Authority inspection is a mandatory regulatory review in Ontario that
ensures electrical installations, equipment, and panels comply with the Ontario Electrical Safety Code before energization or operation. SAFE Engineering Inc. provides complete Electrical Safety Authority inspection coordination and Owner’s Engineer services to help industrial and commercial facilities achieve full regulatory compliance and technical due diligence.

Electrical Safety Authority Inspection in Ontario

The law in Ontario requires that employers and supervisors “take every precaution reasonable in the circumstances” to protect workers under their employ. “Taking every precaution reasonable” is also understood as technical due diligence.

To understand the legal requirements associated with the achievement of technical due diligence one may ask the following questions:

  • What does taking “every precaution reasonable” mean?
  • Reasonable to whom?

The answers to these questions can be found within industry technical standards. Reasonable means reasonable to your peers in your industry. Your industry peers will use your industry technical standards as reasonable practice for your industry. Compliance with the technical standards represents the best engineering practices. A workplace that implements the proper technical standards will have satisfied the due diligence requirement.

When should this Technical Due Diligence be exercised?
  • When purchasing new equipment and processes.
  • When plan relocation and consolidation occurs.
  • Before mergers and acquisitions are undertaken.
The lack of Technical Due Diligence can cause:
  • Personal and corporate liabilities
  • Massive cost overruns from change orders
  • Delays from Government authorities

The Role of an Owner’s Engineer

An Owner’s Engineer is an independent professional engineering firm that represents the facility owner’s interests throughout design, procurement, installation, and inspection. Owner’s Engineer services ensure technical due diligence, regulatory approval, and compliance with ESA, TSSA, and other Ontario authorities.
