In what situation should you wear elbow-length chemical-resistant gloves?

Wearing elbow-length chemical-resistant gloves is particularly important when handling pesticides, as these products can contain harmful chemicals that pose risks to skin and health. The reason for this precaution is that pesticides can be absorbed through the skin, and full coverage is necessary to protect sensitive areas of the body from potential exposure.

Option A states that these gloves should be worn when handling any pesticide, except certain fumigants. This is correct because many pesticides can be potent and hazardous, necessitating robust protective measures to prevent skin contamination. The exception for some fumigants arises from their specific application methods and protective gear recommendations, which might differ from those for liquid formulations.

In contrast, the other options do not encompass the necessary breadth of protective measures required for handling pesticides. The second option limits glove use to only mixing pesticides with water, which diminishes protection during other potential contact scenarios, such as application or cleanup. The third option suggests wearing gloves only for non-toxic products, which is misleading as protective gear is vital for handling any toxic substances. Finally, the fourth option implies that gloves are only necessary for fertilizers, which does not account for the varying risks associated with pesticides, thus underplaying the need for comprehensive protection when dealing with chemicals.
