Question 882 Deck Safety

The correct answer is A) fresh water and soap. To lubricate the swivel or remove corrosion from a fire hose coupling, you should use fresh water and soap. This is because fresh water and soap are gentle, non-abrasive cleaning agents that can effectively remove dirt, grime, and corrosion without damaging the coupling or swivel mechanism. The other options, such as kerosene, glycerin, or graphite, are not recommended as they may damage the coupling or introduce contaminants that could affect the performance of the fire hose.
