What is used to lubricate the zipper on an anti-exposure coverall?

• A. Lubricating oil
• B. Petroleum jelly
• C. Silicone spray
• D. Paraffin Wax

Answer: (D)

Lubricating a zipper on an anti-exposure coverall is about using something that reduces friction without compromising the suit’s chemical protection. Paraffin wax fits this need because it provides a thin, inert coating on the zipper teeth, allowing it to move smoothly and preventing sticking in harsh or field conditions. It won’t leave oily residues that could contaminate the protective barrier or soak into the fabric, which is why it’s preferred over oils, petroleum jelly, or silicone sprays. To use it, clean the zipper, apply a small amount of wax along the teeth, work the zipper back and forth to distribute, and wipe off any excess. Reapply as needed.
