Question 1221 Deck Safety

The correct answer is A) non-toxic gas. Liferafts are typically inflated using a non-toxic compressed gas, usually carbon dioxide (CO2) or nitrogen. These gases are preferred because they are inert, do not support combustion, and are safe for human exposure. Helium, oxygen, and hydrogen are not used to inflate liferafts, as they pose safety risks - helium is expensive, oxygen is flammable, and hydrogen is both flammable and explosive. The use of non-toxic compressed gas to inflate liferafts is a standard requirement specified in maritime safety regulations for US Coast Guard-approved lifesaving equipment.
