Hazardous Locations

Ensure Safe Operation

In Canada, equipment which is used in a Hazardous Location (HazLoc) is required to be certified to specific CSA Standards. The certification process requires a detailed analysis of the subject equipment to ensure that it meets the applicable standards for electrical safety for the specific HazLoc environment. The ultimate objective is to ensure that an electrical fault does not initiate a condition that could lead to the ignition of an airborne flammable substance. ESAFE has a highly-experienced staff of HazLoc specialists. Our scope of certification services cover equipment that is used in explosive atmospheres, as well as equipment for use in non-hazardous locations. ESAFE uses a state of the art Quality Management System with built in safeguards to ensure that the correct process is followed in a HazLoc equipment certification. Our Quality Management System is regularly audited by the Standards Council of Canada to ensure we are in full compliance with ISO-17065.

When your equipment has our mark of approval, you can rest assured that you have met the safety and legal requirements to authorize the use of that equipment anywhere in Canada. As an organization that has been in the electrical equipment inspections business for over 100 years, we bring relevant skills and experience to every job. Over the years, we have evaluated everything from Gas Power Plants to Food Processing Equipment.

Our approach is simple: Safety & Professionalism to deliver a great customer experience.

We are experienced with evaluating equipment that originates from foreign manufacturers. Even if components do not have local approvals from Canadian approval agencies, we can utilize documentation through the IECEx scheme and International Member Country agreements (as authorized by the Standards Council of Canada), to make use of existing approvals to save on certification efforts.

Field Evaluation vs. Hazardous Location Certification

Because of the elevated risk of injury to persons and property involved when certified equipment is used in a Hazardous Location, a significant amount of analysis is required to ensure that Certification is done correctly and no aspect of the equipment or installation is overlooked.

There are many design considerations and methods of protection that can be employed to achieve the minimum level of safety that is required when operating electrical equipment in a hazardous area. A proper analysis and system design starts with the identification of the explosion hazards involved. The industry standard for documenting this is by means of a Hazardous Area Classification Drawing. This drawing needs to be created by a professional engineer who is licensed in the province of the installed equipment.

Every electrical component in the system being certified is individually verified to ensure that it meets the necessary design and approval criteria for use in the intended HazLoc environment. Installation methods are also verified for conformance to the appropriate codes and standards. Approval marks are checked for authenticity and validity for the specific application. Any required testing is performed using NIST (National Institute of Standards and Technology) traceable calibrated instruments. Test results are verified for acceptability and documented. The entire report is carefully reviewed by an independent senior engineer for accuracy. Labels are then applied to conforming product to identify the equipment covered by the detailed certification report.
