When is it essential to utilize a personal flotation device (PFD) in firefighting operations?

Utilizing a personal flotation device (PFD) is essential when working in cold water environments due to the increased risk of drowning and hypothermia. Cold water can significantly impair a person's ability to swim and maintain buoyancy. The effects of cold water can be immediate, leading to loss of dexterity and strength, as well as reducing reaction time. A PFD provides vital buoyancy, helping to keep individuals afloat and increasing their chances of survival in case of an emergency. It acts as a critical safety measure, particularly when responding to incidents involving water rescues or firefighting activities near bodies of water where the risk of falling in is heightened.
