What does the protective hood designed for firefighters protect against?

The protective hood designed for firefighters is specifically engineered to shield the head and neck from extreme heat. This includes thermal radiation and radiant heat that firefighters may encounter in hot environments, particularly during structural fires. The hood is made from flame-resistant materials that provide an additional layer of protection when combined with other personal protective equipment, such as helmets and turnout gear.

While the protective hood does offer some level of protection against other hazards, its primary purpose is to ensure that firefighters can operate safely in high-temperature conditions without suffering burns or heat-related injuries. This thermal protection is crucial, as the head and neck are particularly vulnerable areas during firefighting operations.

The other options, though related to overall safety, do not directly pertain to the primary function of the hood in the context of firefighting.
