American Chemical Society (ACS) Laboratory Safety Test 2025 – 400 Free Practice Questions to Pass the Exam

Question: 1 / 400

When should gloves be worn in a laboratory setting?

Only when handling glassware

Whenever handling chemicals or hazardous materials

Wearing gloves in the laboratory is essential whenever handling chemicals or hazardous materials because they serve as a protective barrier for the skin against harmful substances. This includes not only liquid chemicals but also powders, aerosols, and potentially contaminated glassware. Gloves help prevent exposure to toxic, corrosive, or reactive substances that may cause skin irritations, chemical burns, or systemic toxicity upon contact.

While gloves might be necessary when handling glassware, relying solely on that specific situation could lead to overlooking other hazardous interactions. The same applies to only wearing gloves when working with solids or following the advice of a supervisor; these scenarios do not encompass the comprehensive range of situations where glove use is critical. It is best practice to always don gloves when there is a risk of exposure to harmful materials.
