Exposure suits shall be worn when ditching if the temperature, wind chill corrected, is?

The requirement for wearing exposure suits during ditching relates to the risk of hypothermia and cold-water immersion. When considering the temperature, it is crucial to understand that temperatures at or below 32 degrees Fahrenheit increase the chances of dangerous physiological effects on the body. At this threshold, the risks associated with cold water, which can lead to loss of dexterity, reduced endurance, and other physiological issues, become significant.

Wearing exposure suits when the temperature is equal to or below freezing (32 degrees) ensures that individuals are protected from the immediate risks of cold-water exposure. Exposure suits are designed to insulate the body and retain heat, providing crucial time for survival until rescue. Consequently, the guideline to wear these suits when temperatures are at or below this critical mark is fundamental in ensuring safety during emergencies involving water.

In contrast, temperatures above freezing, even if only slightly, reduce the urgency of donning exposure suits because the risk of hypothermia diminishes, allowing for different types of personal flotation devices or weather gear to be utilized effectively. Thus, it is essential to adhere to the guidance that exposure suits should be worn specifically when the temperature is equal to or below 32 degrees Fahrenheit.
