Multiple Choice

A fire apparatus should not be washed with which?

Explanation:
The main idea is avoiding thermal shock and damage to equipment when cleaning. Extremely hot water can cause rapid temperature changes that stress and distort components such as hoses, seals, gaskets, coatings, and even metal fittings. It can soften rubber parts, crack seals, peel paint, and create leaks or wear problems in the pump and valves. Using cooler water—cold, lukewarm, or tap water—helps prevent these issues while still effectively cleaning the apparatus.
