What type of gloves should be worn when handling concentrated pesticides?

When handling concentrated pesticides, unlined waterproof gloves are the appropriate choice because they provide a barrier that prevents direct contact with harmful chemicals. These gloves are designed specifically for situations where chemical exposure is a concern, ensuring that no substances can seep through and come into contact with the skin.

Lined leather gloves, while durable, may not offer the necessary protection against penetrative chemicals, and the leather itself can absorb some substances. Any fabric gloves do not provide adequate protection against chemicals, as they are porous and allow for the possibility of pesticide exposure to the skin. Rubber gloves with cotton lining might provide some level of protection, but the cotton layer can absorb moisture and chemicals, which can eventually lead to skin contact.

Therefore, unlined waterproof gloves are the best option for effectively safeguarding against the potential hazards of concentrated pesticides.
