Question

Which of the following types of fire extinguishers should not be used to extinguish an electrical fire?

Options

• Carbon dioxide

• Mechanical foam

• Dry chemical powder

• ABC dry powder

Answer 1

Mechanical foam

Explanation:

For electrical fires, it is essential to use non-conductive extinguishing agents. Carbon dioxide and dry powders are safe because they do not conduct electricity and effectively smother the flames without damaging the equipment further or risking the user’s safety.
