Canadian Explosives Research Laboratory

The Canadian Explosives Research Laboratory (CanmetCERL) is the only Canadian government laboratory — and one of few in the world — that offers explosives testing, analysis, certification, and research related to explosives and their components. Our clients include national and international public and private partners. CanmetCERL is accredited under ISO/IEC17025:2017 and features state-of-the-art capabilities.

Testing and analysis services

We offer tests and analyses (hazard testing, performance testing, chemical analysis and more) for three main purposes:

  • Authorizing or certifying components and products to ensure their safe and effective use as they go to market
  • Ensuring that processes pertaining to explosives and other unstable substances (manufacture, transport, use, etc.) are safe and effective
  • Mitigating the risk of intentional threats to the public

Explosives authorization and certification

Are you a manufacturer, transporter, seller or operator who wants their explosive product or component to appear on Canada’s authorized products list? Or do you need to have it certified for product trials under the Explosives Act and Explosives Regulations? We support Canada’s Chief Inspector of Explosives and the NRCan Explosives Regulatory Division in making such assessments.

We test a wide range of products, including blasting/industrial explosives and accessories, ballistics and sport ammunition, pyrotechnics propellants (i.e., fireworks), model rocket motors, toy pistol caps and automobile components. These tests ensure that only safe products make it to market, and that innovation and safety go hand in hand as new products are developed.

You can learn more about product authorization here.

Safety and process hazards

Are the explosive products you handle and the processes you use to manufacture, transport, acquire, store, sell or operate them safe?

We conduct testing to analyze blast potential and conduct risk assessments — including quantified risk assessments (QRA) — and hazards characterizations to ensure that explosives are handled and stored safely from manufacture through to initiation by the end user. We also work with government departments (e.g., Transport Canada) to ensure that explosives-related policies are sound.

Examples of our work
Pyrotechnics
  • Testing hundreds of fireworks mortars and rating their safety based on fragmentation and throw distance
  • Evaluating mortar racks to assess their safety in the event of a violent in-mortar explosion
  • Analyzing the process within a perforating gun shop to determine the hazards associated with their loading and storage areas
  • Designing and prototyping fireworks mortars
Process hazards
  • Evaluating risks of runaway reactions during manufacture of metal alloys for the aeronautics industry
  • Analyzing the compatibility of ammonium nitrate with various plant chemicals
  • Quantifying the risks of producing a detonation following localized ignitions in the propellant industry
  • Evaluating the explosion risk of explosives pumps in the mining industry

Security and emerging threats

New explosive or pyrotechnic compositions — including those used for homemade explosives (HMEs) — pose potential threats to public safety. We are part of an international effort to examine the chemical and physical properties, improve our identification and detection capabilities, and inhibit the unlawful use of these compositions. We also work to understand the potential effects of explosives used to cause intentional harm to the public or public infrastructure.

We conduct precursor chemical testing to evaluate the hazards, properties and feasibility of HME manufacture and the potential uses of these materials. This information is used to support the development of relevant, science-based regulation, as well as to help law enforcement personnel with their efforts to keep Canadians safe.

We also focus on the effects of explosives by evaluating risks of intentional threats to the integrity of the Government of Canada’s critical infrastructure in Canada and abroad (bridges, dams, embassies, etc.), and by assessing the biomechanics of blast injury (e.g., risks to the public from an attack, risks of injury to law enforcement personnel during tactical exercises). The results of our work also inform and improve the design of infrastructure and personal protective equipment as well as the approaches/equipment used by trauma response teams.

Examples of our work

We conduct small-scale testing at the lab in Ottawa and occasionally perform large-scale tests using military ranges at CFB Petawawa (Ontario) and CFB Suffield (Alberta). Our world-class technology also includes shock tube testing (compressed air to simulate a blast wave) and numerical software tools (i.e., computer modeling and analytics for explosions that cannot be conducted in real life).

Interaction of blast waves with structures and the human body
  • Studying the blast response of hardened structures and glazing
  • Evaluating the risks of overpressure exposure to law enforcement personnel during tactical explosive operations
  • Assessing critical energy infrastructure (pipelines, nuclear power facilities, electrical generation and distribution facilities such as dams) to evaluate their vulnerabilities against explosive loads
Equipment for handling explosives safely
  • Developing containers for the RCMP Explosive Disposal Unit
  • Developing and conducting tests to evaluate the performance of bomb suits, helmets and other accessories
  • Designing and installing robot-controlled processes for energetic materials

Collaborate with us

Featured paper

Minimum burning pressures of water-based emulsion explosives

Pumping water-based emulsion explosives for blasting applications can be very hazardous. Over 10 years, we developed a protocol for measuring the minimum pressure required for the sustained burning of water-based emulsion explosives. Use it as a guide to characterize the behaviour of these products in your pumping systems.
