At what water temperature should quick donning anti-exposure suits be available for HSB crews?

Quick donning anti-exposure suits are essential for protecting personnel from hypothermia in water temperatures that can pose significant risks. The industry standard indicates that these suits should be readily available when water temperatures drop to 60 degrees Fahrenheit. At this temperature, there's a heightened risk of cold water immersion, which can lead to serious health complications including hypothermia.

Personnel need to be prepared for quick access to anti-exposure suits to ensure they can rapidly respond to emergencies at sea, particularly when operating in colder waters. The 60 degrees Fahrenheit threshold effectively balances the need for safety with operational readiness, as exposure to temperatures below this level significantly increases the likelihood of cold-related health issues. Thus, the correct choice reflects a critical understanding of safety protocols for HSB crews in potentially hazardous marine environments.
