What type of clothing can ignite due to molten metal splatter during an arcing fault?

Flammable clothing is a significant concern in environments where there is a risk of molten metal splatter, which can occur during an arcing fault. Materials that are flammable can easily ignite when they come into contact with hot, molten substances, leading to severe burns or other injuries.

Protective clothing is specifically designed to resist ignition and protect the wearer from hazardous situations, while waterproof clothing typically focuses on preventing water from penetrating, having little relevance to the ignition risk from molten metal. Non-conductive clothing helps in preventing electrical hazards but does not inherently address the risk of burning or melting when exposed to molten materials. Therefore, flammable clothing poses a real danger in such scenarios and should be avoided in any workplace where molten metal splatter is a possibility.
