Under which circumstance do disposable gloves provide limited chemical protection?

• A. When exposed to strong organic solvents for extended periods
• B. When used for short contact with dilute aqueous solutions
• C. When handling dry, inert powders
• D. When worn in a clean, dry environment with no chemical exposure

Answer: (A)

Verified step by step guidance

1. Understand that disposable gloves are designed to provide a barrier against certain chemicals, but their effectiveness depends on the type of chemical and the duration of exposure.
2. Recognize that strong organic solvents can degrade many glove materials, especially if the exposure is prolonged, reducing the gloves' protective ability.
3. Note that short contact with dilute aqueous solutions generally poses less risk of glove degradation, so protection is usually adequate in these cases.
4. Consider that handling dry, inert powders or wearing gloves in a clean, dry environment without chemical exposure does not challenge the gloves' chemical resistance.
5. Conclude that disposable gloves provide limited chemical protection specifically when exposed to strong organic solvents for extended periods, due to material breakdown and permeation.
