Which type of gloves are considered inappropriate for personal protective equipment (PPE) when handling pesticides?

Leather and canvas gloves are considered inappropriate for personal protective equipment (PPE) when handling pesticides primarily because they do not provide sufficient chemical resistance. Pesticides can be hazardous substances that may easily penetrate these materials, leading to potential skin exposure and a higher risk of chemical burns or other harmful effects.

In contrast, rubber, silicone, and nitrile gloves are specifically designed to offer better protection against a range of chemicals, including pesticides. These materials are resistant to many types of chemicals and provide a secure barrier, reducing the likelihood of harmful substances coming into contact with the skin. Therefore, using leather and canvas gloves is not advisable for pesticide handling, as they do not adequately protect the user from the risks associated with these chemicals.
