When is it necessary to use a fire blanket?

The necessity of using a fire blanket is primarily associated with smothering small fires or protecting equipment from fire hazards. Fire blankets are designed to extinguish small, contained fires by depriving them of oxygen. They are typically made of flame-retardant materials and can be quickly deployed over a fire to effectively smother it.

Using a fire blanket is particularly useful in environments where quick action is needed to prevent a small fire from escalating. They are also beneficial in protecting sensitive equipment from heat or flames, preventing further damage or fire spread. This method is especially efficient in areas where water or other extinguishing agents may not be suitable, such as in kitchens or industrial settings with electrical fires.

The other options describe scenarios that are not suitable for the specific application of a fire blanket, further highlighting why using a fire blanket for small fires or equipment protection is the most appropriate answer.
