Question 1425 Deck Safety

The correct answer is B) They provide sufficient flotation to do away with the necessity of wearing a life jacket. Immersion suits are designed to provide thermal protection and limited flotation in cold water emergencies. However, they do not provide enough flotation on their own to replace the need for a properly fitted life jacket. Regulations require that immersion suits be worn in conjunction with a USCG-approved life jacket when operating in cold water environments. The other options are incorrect: A) Immersion suits should fit loosely to allow for insulation layers underneath. C) A puncture in the suit can significantly reduce its thermal protection and buoyancy. D) Wearing only light clothing underneath the suit may not provide adequate insulation in cold water.
