Canada Gazette, Part I, Volume 155, Number 23: Regulations Amending the Explosives Regulations, 2013 (Restricted Components)

The Government of Canada has a vital role to play where access to explosives precursor chemicals is concerned. Of importance are the chemicals used to make homemade explosives (HMEs), which are commonly referred to as explosives precursor chemicals (termed “restricted components” for those that are subject to the Explosives Regulations, 2013 [the Regulations]). Given the rise in large-scale attacks involving HMEs among Canada's allies, proactive government action is needed in trying to mitigate potential threats before events occur. As part of the ongoing commitment of Natural Resources Canada (NRCan) to the safety and security of Canadians and to further align the Canadian approach with that of international allies, NRCan constantly reviews and updates the Regulations to address national security issues. Substances such as calcium ammonium nitrate (CAN), hexamSine, aluminum powder and acetone were used in international attacks and in threats from domestic extremists in Canada. The Government must ensure the proper level of control for certain sale and storage activities in relation to these substances. The current list of restricted components in the Regulations must be proactively updated to capture any chemicals that could be a threat to the safety of Canadians. Regulating the acquisition and sale of calcium ammonium nitrate, hexamine, aluminum powder and acetone (the four chemicals) would strengthen security and help identify suspicious activities (tampering, theft and suspicious purchases). It would enable enforcement activities with respect to the sale and secure storage of these chemicals, hence reducing the making of HMEs in Canada.

Background

The Explosives Act (the Act) and the Regulations regulate the manufacturing, testing, acquisition, possession, sale, storage, transportation, importation and exportation of explosives, the use of fireworks, and specifies security measures relating to restricted components. The main objectives of the Act are to ensure public safety and to strengthen national security. Part 20 of the Regulations restricts the acquisition and sale of restricted components and sets out the requirements for their acquisition, sale and secure storage. Currently, there are 10 restricted components listed in the Regulations. The Regulations have increased controls on the sale and on the use of these restricted components by members of the general public and improved the reporting of suspicious transactions. However, other chemicals have been used for the manufacture of HMEs and have shown to be problematic in other countries. The misuse of these chemicals is a threat to the safety and security of Canadians.

Legitimate use

The four chemicals have many legitimate uses and are available through manufacturers, distributors and a variety of retailers (primarily department stores, hardware stores, pharmacies, outdoor stores, discount stores, agriculture stores and paint stores). Calcium ammonium nitrate is primarily used as a fertilizer, preferably on acid soil. It is also an ingredient in some instant cold packs. These packs have a pouch of either ammonium nitrate (AN) or calcium ammonium nitrate (CAN) and a separate pouch of water. When the pouch is broken and the AN or CAN mixes with the water, an endothermic reaction occurs and the pack becomes cold. These are different from the gel packs that need to be put into a freezer to get cold. Hexamine is utilized as a curing agent for phenolic resins, petroleum production, food and agriculture, pharmaceuticals, rubber vulcanization, corrosion inhibitor and in explosives. Hexamine is also the primary ingredient in camping stove fuel tablets. Aluminum powder is commonly used in the manufacture of silver metallic pigments for coatings, electronics and packaging, added to form lightweight concrete, is utilized as an alloying agent, and as fuel in explosives, pyrotechnics and propellants. Aluminum powder is also utilized by sculptors and in the marine sector due to its corrosion resistance. Acetone is utilized as an industrial and laboratory solvent, paint thinner/cleaner, degreaser, and nail polish remover.

Terrorist use

Calcium ammonium nitrate-based HMEs have been used in many terrorist events in Europe and Afghanistan. Over half the explosive devices found or detonated in Afghanistan are made from ammonium nitrate (AN) that was derived from calcium ammonium nitrate. Hexamine was used in Ontario by a person who pledged allegiance to ISIS for making an HME with the intent of carrying out an attack in Ontario. Hexamine was also used in the explosives that detonated during the Mumbai railway attacks in 2006. Aluminum powder is commonly used and can be found in most recipes as a fuel to make a variety of homemade explosive formulations. Aluminum powder was part of the explosive used in the Parkdale blast in Alberta in 2018. Acetone is an ingredient required for making triacetone triperoxide explosives that have been used in terrorist attacks such as the London subway bombings (2005), the Paris attacks (2015), the Brussels bombings (2016 and 2017) and the Manchester Arena bombing (2017).

Objective

The primary objective of the proposed amendments is to strengthen the security regime for restricted components by updating the list of restricted components in the Regulations to include the four additional chemicals of concern. Imposing regulatory measures on calcium ammonium nitrate, hexamine, aluminum powder and acetone would place security controls on their sale and storage in order to minimize illegitimate access to the chemicals. Law enforcement would be made aware of any tampering, theft or suspicious sales. The proposed amendments would also make administrative amendments to Part 20 of the Regulations to clarify intent.

Description

  1. change the structure of Part 20 to create a three-tiered layout;
  2. update the list of restricted components;
  3. add ammonium nitrate and calcium ammonium nitrate contained in cold packs as Tier 3 restricted components;
  4. use Chemical Abstracts Service registry numbers (CAS RN) to define restricted components; and
  5. make administrative changes.

1. Change the structure of Part 20 to a three-tiered layout

Currently, Part 20 of the Regulations has many sections on regulatory requirements. Some sections are common to all restricted components and some sections outline specific regulatory requirements for either ammonium nitrate or for the other nine restricted components. As ammonium nitrate is the restricted component with the highest-risk, there are more regulatory requirements for sale and storage than the other nine restricted components.

The proposed amendment would change the layout of the sections in order to increase ease-of-use and provide more clarity around the requirements for each restricted component by creating three separate divisions; Tier 1, Tier 2 and Tier 3.

Within each tier, stakeholders would be able to clearly see all requirements pertaining to their specific restricted component. The structure would be such that restricted components that fall within Tier 1 have the most requirements whereas the ones in Tier 3 have the least.

This new structure would not impact the number of requirements for restricted components that are already included in the Regulations.

2. Update the list of restricted components

The following chemicals would be added to the current list of 10 restricted components:
