What distinguishes a fire blanket from a fire extinguisher?

The distinguishing feature of a fire blanket is that it smothers the fire rather than spraying or discharging a substance. When a fire blanket is deployed, it is placed over the flames to cut off the fire’s oxygen supply, which is essential for combustion. This method is effective for small, contained fires, particularly those involving cooking or fabric materials, as the blanket can cover and smother the flames securely.

Other options do not accurately describe the fundamental operation of a fire blanket. For instance, fire blankets do not use foam; instead, they are typically made from materials that can withstand heat and block oxygen. They also do not require any electrical power or batteries to function, making them straightforward and accessible emergency tools. Additionally, while a fire blanket can be thrown over a fire, this is not its primary design purpose; rather, it is meant to be placed carefully over an ignition source to effectively suffocate the flames.
