Hazardous Locations (HazLoc) – Also known as Explosive Atmospheres – are found in a variety of places: Coal mines and coal handling facilities, refineries, oil and gas wells, pipelines, gas stations, chemical plants, paint shops, textile mills, flour mills, oil/gas/grain tankers, grain elevators, automobile manufacturing, automotive repair shops, food producers, distilleries, and sewage treatment plants, etc. To know more about hazardous locations please see our White Paper on this topic
If you manufacture or supply equipment for these types of locations, you are required by law to meet the applicable safety standards and to ensure that your product is tested and approved.

Certification for the USA
In the USA, regulations pertaining to the installation of HazLoc equipment are covered in the National Electrical Code (NEC), which includes details on equipment construction, performance, installation requirements, and area classification requirements. In addition, approval of HazLoc products not used in the mines is also Federally covered under OSHA (Occupational Health and Safety Administration) regulations.
Article 500.8(A)1 of the NEC gives manufacturers several choices to determine suitability of HazLoc equipment, as follows:
a. Equipment listing or labeling (by a Nationally Recognized Testing Laboratory-NRTL), or
b. Evidence of equipment evaluation from a qualified testing laboratory or inspection agency concerned with product evaluation, or
c. Evidence acceptable to the Authority Having Jurisdiction (AHJ) such as a manufacturer’s self-evaluation or an owner’s engineering judgment.
OSHA regulations pertaining to installation of hazardous classified equipment stipulate the following:
- Regulation 29 CFR 1910.307(b) states: “Equipment, wiring methods and installation of equipment in hazardous (classified) locations shall be intrinsically safe, approved for hazardous (classified) locations, or safe for the hazardous (classified) location”.
- Paragraph 1910.307(b)(3) defines “safe” as follows: “Equipment which is safe for the location shall be of a type and design which the employer demonstrates will provide protection from the hazards arising from the combustibility and flammability of vapors, liquids, gases, dusts, or fibers”.
Our extensive accreditations in the USA by OSHA (as NRTL), by IAS (as a Certification Body), and by A2LA (as a Test Lab) cover HazLoc equipment. QPS will test and evaluate the product to the relevant UL standards. Complying products will bear the QPSus Certification Mark as shown below.
Where “Regular Certification” is impractical, QPS offers Field Certification whereby the product is tested and evaluated on-site to the applicable requirements and, if it complies, will be labelled by the QPS representative with a serialized Field Certification Label, as shown below.
Certification for Canada
Regulations pertaining to the installation of HazLoc equipment is covered in Part I of the Canadian Electrical Code (CEC). The Code includes details on equipment construction, performance, installation requirements, and area classification requirements.
HazLoc products sold in Canada must be tested and certified by an SCC (Standards Council of Canada) accredited certification body to the requirements of the Code, as well as to the appropriate equipment standards covering specific protection methods.
Our accreditations in Canada covers all product categories (under the Division system) and all protection methods (under the Zone system). We will assess the conformity of your product to the Canadian Electrical Code and the applicable CSA equipment standards. Complying products certified under the ISO Type 3 Certification System (“regular certification”) will bear the cQPS Certification Mark shown below, which is readily recognized Canada-wide.
Where Regular Certification is impractical, QPS offers an alternative ISO Type 1 Certification System known as Field Certification. Under this option, the product is tested and evaluated to the applicable requirements and, if it complies, will be labeled by the QPS representative with a serialized Field Certification Label, as shown below.
Certification for the USA and Canada
If you sell your products in the USA and Canada, then such products must be tested and certified to the requirements of both countries, and complying products must bear the Certification Mark (or Field Certification Label) shown below.
MSHA Part 6 Approvals of Mining Products
If you sell your products for use in the mines, you must obtain MSHA approval. Being a recognized lab under MSHA Part 6 Approval of Mining Products program, QPS can provide valuable assistance by testing and evaluating your product to MSHA standards.
Equipment used in mines is covered under the Federal Safety and Health Act of 1977 (the Mine Act), which applies to all mines and mineral processing operations in the U.S. regardless of size, number of employees, or method of extraction. U.S Federal regulations enacted under this Act require that mining products intended for use in underground mines be tested/evaluated and approved by MSHA (Mine Safety and Health Administration). However, MSHA has in place a program (MSHA Part 6 Approvals of Mining Products) whereby MSHA accepts testing and evaluation by recognized independent laboratories in lieu of MSHA performing their own testing and evaluation.
QPS is an accredited NRTL (Nationally Recognized Testing Laboratory) and is recognized by MSHA under the above mentioned acceptance program. As such, QPS will test and evaluate the product to ensure it meets the applicable MSHA standard (or non-MSHA Product Safety Standards – equivalent to the applicable product approval requirements having the same degree of protection) and compile the required technical documentation package for submittal to, and review and approval by MSHA.
We work very closely with MSHA staff to ensure that when the work is completed, you have a test/evaluation report from QPS that is readily accepted by MSHA, thus granting you just-in-time approval. So if you have products destined for the USA for use in mines, and if you need faster approval, we can help!
Under MSHA’s Subchapter B – Testing, Evaluation, and Approval of Mining Products – Part 6, the products that are required to be evaluated and tested range from small electronic devices to large mining systems, such as:
- Battery Powered Mobile Machines
- Batteries for Mobile Machines
- X/P Connection Boxes/Enclosures
- X/P Plug and Receptacles/Connectors
- Diesel Electronics
- Electric Cap Lamps
- X/P Electric Motors
- Permissible Fans
- Ground Check (Wire) Monitors
- Intrinsically Safe Instruments
- Intrinsically Safe Relays
- Lighting Systems
- Communication Systems
- Multi-Gas Detectors – Handheld
- Machine Methane Monitoring Systems
- Telephone and Signaling Devices
- Water Pumps
