For an ordinary type of hazard, what is the basic minimum extinguisher rating?

For an ordinary type of hazard, such as those found in typical workplaces where flammable materials are present, the basic minimum extinguisher rating is 10-B. This rating reflects the effectiveness of a fire extinguisher in extinguishing flames from flammable liquids, vital for ensuring safety in environments like offices, warehouses, and similar settings.

The rating system uses the letter "B" to denote the class of fire involving flammable liquids. A 10-B rating indicates that the extinguisher has been tested and found capable of extinguishing a fire involving ten square feet of flammable liquid. This standard helps ensure that fire extinguishers are adequately capable of handling potential fire scenarios in everyday environments.

Choosing extinguishers with this minimum rating aids in compliance with safety regulations and promotes better fire safety practices within facilities.
