We work with QPS (Certification body in Canada), providing expertise / consulting and Canadian Certification for hazardous location devices,  Intrinsically Safe Circuits (Exia), Explosion-Poof devices and critical safety circuits,(sometimes referred to as; C1D1, C1D2 certification )

We also conduct Failure Mode Effects Analysis (FMEA) and “Combustion Safety Control” Certification. We also certify LED lighting systems for Class I, Div 2 hazardous locations for the Canadian and US market place.  “Explosive Fluid Seal” testing for gas tightness and secondary seals is also part of our repertoire.  Having offices throughout Alberta makes it convenient for Canadian or USA certification.


If you are a manufacture or supplier of electrical / electronic equipment for the oil and gas industry- We are the ones to contact to get your product to market and certified to CSA (Canadian Standards Association) or UL standards.  We used to be partners with Entela; now we have grown to be the most efficient certifiers for hazardous location in the oil and gas industry throughout North America. If you need to get your Hazloc **    product certified fast and efficiently- we are the ones that can help.


** The definition of “hazloc certification” :  In electrical engineering, hazardous locations ( C1D1 _  C1D2 certification ) is sometimes abbreviated to HazLoc, pronounced Haz•Lōk or Haz•LoK   



For an official quote regarding hazardous location certification or “Hazloc”  consultation, Simply click on “application” and “Component form” (above)- SAVE TO YOUR DESKTOP;  Fill in the blanks as best you can and return via email (bstephenson@QPS.ca).

We will email you within a couple of days a detailed quote and the applicable paperwork to start your  products certification, evaluation and/or testing- (If you do not receive it in a couple of working days please call us at 780-905-9601) Make sure to save the file on your desktop just in case it gets lost in cyberspace. Then call us for an appointment. If the device is relatively small, you can also send us a sample at the same time to facilitate the process.
