The scenario described pertains to the body's natural response to heat exposure and the recovery process after strenuous physical activity. When a firefighter removes their turnout gear to cool down in a cooler environment, it initiates a process known as passive cooling.

Passive cooling occurs when the body is allowed to cool down without any active measures being taken to enhance the cooling process, such as water immersion or the use of cooling vests. By simply removing the gear, which retains heat, and allowing the body to be exposed to a cooler environment, the firefighter's body temperature can gradually decrease. This process relies on the natural heat dissipation methods of the body, such as radiation and convection, which are facilitated by the cooler surroundings.

In contrast, active cooling involves methods where external interventions, such as fans, water sprays, or cooling towels, are employed to enhance the rate of heat loss from the body. Other options, like thermal recovery or heat stress management, encompass broader terms that could include various strategies for recovering from heat exposure, but they do not specifically define the natural cooling process occurring when gear is removed in a cooler environment. The retention of heat by turnout gear can lead to overheating, thus removing it leads directly to passive cooling, making it the correct choice in this context
