What is the process of controlling fumes that are given off by flammable liquids called?

Vapour suppression is the process of controlling fumes emitted by flammable liquids. This technique is crucial in managing the risks associated with hazardous materials, as it minimizes the concentration of vapours in the air, thereby reducing the likelihood of ignition and subsequent fire or explosion. Vapour suppression can involve various methods such as the application of foam or other agents designed to cover the liquid’s surface, effectively preventing vapours from escaping into the atmosphere.

The role of vapour suppression is fundamental in hazardous material incidents, particularly in scenarios where flammable liquids are involved, since it directly addresses the danger posed by their vapours. By effectively managing vapour release, responders can create a safer environment for themselves and the public while working to mitigate the incident.

In contrast, while eliminating ignition sources, dilution, and positive pressure ventilation are all important safety measures in hazmat scenarios, they do not specifically address the management and control of vapour emissions from flammable liquids in the same direct and proactive way that vapour suppression does.
