Final answer:
The statement that leather or fabric gloves' primary disadvantage when handling pesticides is staining is false; their actual disadvantage is the potential for pesticide absorption through the material, posing significant health risks.
Step-by-step explanation:
The primary disadvantage of leather or fabric gloves when handling pesticides is that they can absorb the chemicals, which may then pass through the material and come into contact with the skin. This is not only a matter of staining but a significant health risk, because pesticides can be hazardous to human health if absorbed through the skin. Protective gloves designed specifically for handling pesticides are usually made of materials like nitrile, which are more resistant to chemicals and provide better protection against possible pesticide exposure. Agricultural workers, pesticide formulators, and manufacturers are particularly at risk for pesticide-related illnesses due to extensive exposure, which highlights the importance of using the correct protective equipment.
