Flashcards

Lab shoe requirements

Lab shoes must fully cover the foot, including the top, and cannot be open-toed (like thongs or sandals); leather is a common material due to its durability and chemical resistance.

Foot protection in a lab environment

If working with hot, corrosive, or poisonous substances, foot protection must include shoes that completely enclose the foot.

Butyl glove uses

Butyl gloves are suitable for a wide variety of chemicals, including peroxides and strong acids (like nitric and sulfuric acid), as well as some bases, alcohols, and ketones.

Butyl glove limitations

Butyl gloves should not be used with certain chemicals like aliphatic, aromatic hydrocarbons, and halogenated solvents, as they might not offer sufficient protection.
