Question

which is the best place to store a toxic chemical, like insecticide, in a food premises?
in the dry storage area, below all food products
in a locked maintenance closet
on a shelf over a dishwashing sink
next to food

Explanation:

Toxic chemicals like insecticides should be stored securely to prevent contamination of food. A locked maintenance closet provides security and separation from food. Storing below food products (risk of spillage onto food), over a sink (potential for accidental release into food - related areas), or next to food (direct contamination risk) are all unsafe.

Answer:

In a locked maintenance closet
