B.The product is moderately toxic

Wearing appropriate PPE, especially chemical-resistant gloves and coveralls, is critical to reduce dermal exposure.

10Which type of PPE should always be worn when mixing concentrated pesticides unless the label specifies otherwise?

A.Safety glasses only

B.Dust mask only

C.Chemical-resistant gloves

D.Steel-toed boots

Explanation: Chemical-resistant gloves should always be worn when handling concentrated pesticides during mixing and loading operations unless the label specifically states otherwise.
