For flammable gases, which class of extinguisher should be used?

For flammable gases, the appropriate class of extinguisher is Class C. This class is specifically designed to tackle fires that involve energized electrical equipment and flammable gases or vapors.

Using Class C extinguishers, which usually contain non-conductive agents like carbon dioxide or dry chemical powders, ensures safety while extinguishing fires involving gas. These extinguishing agents effectively smother the flames without conducting electricity, making them suitable for use in environments where flammable gases are present.

In contrast, other classes of extinguishers are tailored for specific types of fires: Class A is for ordinary combustible materials, Class B is intended for flammable liquids, and Class D is for combustible metals. Therefore, selecting a Class C extinguisher for flammable gas fires is critical to both effective fire suppression and safety.
