What type of firefighting protective clothing provides a moisture barrier to shield against steam burns?

The correct choice is focused on the type of clothing specifically designed to mitigate the risks associated with steam burns by providing an effective moisture barrier. Wicking body gear is designed to draw moisture away from the skin while also offering a layer of protection against hot surfaces and steam. This is crucial for firefighting scenarios where steam and heat can rapidly escalate the risk of burns.

The nature of wicking fabrics allows for moisture management, reducing the likelihood of steam traps between the skin and the garment, which can lead to burns. This characteristic is essential in an emergency environment like firefighting, where maintaining body temperature and protecting against burns is a priority.

Other types of clothing mentioned may offer various levels of heat protection but do not specifically have the moisture-wicking properties necessary to protect against steam burns. Nomex suits are well-regarded for their flame-resistant properties but do not necessarily provide the same moisture barrier as wicking gear. Polyester uniforms, while durable, lack the necessary thermal protection and moisture management features. Leather gloves are primarily protective for hand safety but do not encompass full-body moisture barrier capabilities.
