When fighting a wildland fire, which type of clothing is considered unsafe to wear?

Synthetic underclothing is considered unsafe to wear when fighting a wildland fire because it can melt and adhere to the skin when exposed to high heat or flames. This can lead to severe burns and injuries that are difficult to treat. In environments where firefighters are exposed to extreme conditions, it is crucial to wear materials that will not react detrimentally to heat.

In contrast, fire-resistant clothing is specifically designed to withstand high temperatures and protect against flames, making it essential for safety in firefighting scenarios. Cotton underclothing is generally safer than synthetic options since it doesn’t have the same melting risk, and leather boots provide protection against embers and rough terrain. Therefore, opting for natural or treated materials that enhance safety is vital in wildland firefighting.
