Question 435 Deck Safety

The correct answer is D) a sponge used to mop up and store condensation must be kept salt free. When collecting condensation for drinking water, it is important to avoid contamination. Using a sponge to mop up the condensation is a common method, but the sponge must be kept salt-free to prevent the water from becoming salinized. This is a key requirement specified in US Coast Guard regulations for collecting potable water. The other options are incorrect because they either do not address the issue of salt contamination (A, B, C) or are not standard practices for collecting drinking water from condensation.
