What material is best suited for shoes worn while spraying chemicals?

• A. Rubber
• B. Leather
• C. Canvas
• D. Metal

Answer: (A)

Chemical-resistant footwear is essential when spraying chemicals to protect feet from splashes and potential permeation. Rubber is the best choice because it forms an impermeable barrier that resists many solvents and corrosive liquids, keeping chemicals from soaking through to the skin and allowing easier cleaning after exposure. Leather can absorb liquids and degrade with certain solvents, reducing protection. Canvas is porous and readily absorbs chemicals, offering poor protection. Metal isn’t suitable for footwear in this context, as it doesn’t provide a flexible, chemical-resistant barrier and isn’t practical for footwear material.
