What is one purpose of wearing flame-resistant (FR) clothing?

Wearing flame-resistant (FR) clothing is primarily designed to prevent burns in work environments where there is a risk of exposure to flames or electrical arcs. These specialized garments are made from materials that are inherently flame-resistant, meaning they won't ignite easily and will self-extinguish when the source of the fire is removed. This characteristic significantly reduces the risk of severe burns to the wearer by providing a protective barrier against heat and flames.

In contrast, enhancing visibility, allowing for easier movement, or keeping warm do not encompass the primary protective function that FR clothing serves. While visibility can be addressed through other types of high-visibility apparel, and movement can often be a concern for general workwear, the foremost purpose of FR clothing is to protect individuals from fire-related hazards.
