What type of extinguisher should be onsite during asbestos work?

The appropriate type of extinguisher to have onsite during asbestos work is a Class B fire extinguisher. Class B extinguishers are specifically designed to combat fires that involve flammable liquids and gases, which can arise from common materials and equipment used in construction and maintenance tasks, including those associated with asbestos-related activities.

In situations where asbestos material is being disturbed, there is a potential risk of fire from flammable materials being present, making it crucial to have the right extinguishing agent readily available. Class B extinguishers are effective in controlling these types of fires, which makes them a fitting choice for ensuring safety on a site where hazardous materials are handled.

While other extinguisher types, like Class C, are adept for electrical fires, and water-based extinguishers may not be suitable for all fire types due to their water content potentially exacerbating certain fires, the Class B extinguisher is the most relevant for the types of hazards typically associated with asbestos work. An ABC fire extinguisher might appear versatile because it can handle a range of fire classes, but the specificity and effectiveness of the Class B for flammable liquids provide an added layer of safety for that particular worksite.
