Which clothing material is recommended for personnel who handle or install unpackaged electrically initiated devices?

• A. Polyester
• B. Cotton
• C. Wool
• D. Nylon

Answer: (A)

The main idea is choosing clothing that minimizes static electricity and ignition risk when handling devices that can be sparked or initiated electrically. Cotton is the best choice because, as a natural fiber, it tends to generate less static and is less likely to melt or fuse to the skin if a discharge occurs. Synthetic fabrics like polyester or nylon can build up static charges more readily and may ignite or melt, increasing the danger around electrically initiated devices. Wool, while flame resistant in some cases, can still generate static and isn’t as reliable as cotton for this specific risk. So cotton reduces the chance of a static discharge causing ignition, making it the safer option here.
