burn or leaving the spill alone (except to use a dike to prevent its spreading) until additional technical advice can be obtained. Refer to the 2024 Emergency Response Guidebook - a PDF copy of ERG2024 is available on the Transport Canada website. The applicable guides in ERG2020 clearly warn of potentially dangerous reactions. For water reactive materials, technical advice is required because: • Water may cause an explosion inside a ruptured or leaking container. • Water may be needed to cool adjoining containers to prevent their rupturing (exploding) or further spread of the fires. • Water may be effective in mitigating an incident involving a water-reactive material only if it can be applied at a sufficient flooding rate for an extended period. The products from the reaction with water may be more toxic, corrosive, or otherwise more undesirable than the product of the fire without water applied.
Vapour Control
Limiting the amount of vapour released from a pool of flammable or corrosive liquids is an operational concern. It requires the use of specialized equipment, appropriate chemical agents, and skilled personnel wearing proper protective clothing. Before engaging in vapour control, get advice from an authoritative source as to the proper tactics. Vapour control methods must be selected for the specific material involved and performed in a manner that will mitigate, not worsen, the incident. There are several ways to minimize the amount of vapours escaping from pools of spilled liquids, such as: • Special foams, • Adsorbing agents, • Absorbing agents, and • Neutralizing agents When specific hazardous materials at a refinery or storage facility are known, the facility should pre-select and stockpile vapour control agents in case of a spill. If the available foam is inappropriate for use, response personnel are likely to use water spray. Because water is being used to form a vapour seal, care must be taken not to churn or further spread the spill during application.
