What type of personal protective equipment might be needed when working near flammable materials?

When working near flammable materials, the use of fire-resistant clothing is crucial for ensuring safety. Fire-resistant clothing is specifically designed to resist ignition and to protect the wearer from burns when exposed to flames or high heat. This type of personal protective equipment is made from special materials that do not ignite easily and have properties that can minimize the severity of injuries in the event of a fire.

In contrast, heavy-duty boots are important for foot protection in various work environments but do not offer the necessary flame resistance. Standard office wear typically does not include protective features for hazard-laden environments, and safety goggles are essential for eye protection but do not address the risk posed by fire and heat when flammable materials are present. Hence, fire-resistant clothing stands out as the most relevant choice for those working in proximity to flammable substances.
