Question 705 Deck Safety

The correct answer is B) nonconducting. Fire extinguishing agents used on Class C fires, which are electrical fires, must be nonconducting. This is because the extinguishing agent must not conduct electricity, as that could pose a risk of electric shock to the person operating the fire extinguisher. Water-based agents (option C) are not suitable for Class C fires as they are conductive. The other options, while important for other fire classes, are not the primary requirement for Class C fire extinguishers.
