Which types of portable fire extinguishers are designed for use on electrical fires?

A Carbon dioxide and foam (stored pressure)
B Dry chemical and carbon dioxide
C Dry chemical and soda-acid
D Foam (stored pressure) and soda-acid
AI Explanation

The correct answer is B) Dry chemical and carbon dioxide. These types of portable fire extinguishers are designed for use on electrical fires because they are non-conductive, meaning they will not conduct electricity back to the user. Dry chemical extinguishers smother the fire by interrupting the chemical reaction, while carbon dioxide extinguishers work by displacing oxygen. The other options, such as foam and soda-acid, are not suitable for electrical fires as they can potentially conduct electricity.
