Which emergency number must be posted near pesticide storage?

The correct choice is the local hospital because it is critical to have immediate access to emergency medical assistance in the event of pesticide exposure or related incidents. Pesticides can be hazardous to health, and having the number for the local hospital readily available ensures that individuals can swiftly seek medical help. Quick communication can be vital in emergency situations where time is of the essence, such as in cases of poisoning or severe allergic reactions.

The other options do not provide relevant immediate emergency response for pesticide-related incidents. While local post offices, schools, and grocery stores are important community resources, they do not offer direct medical care, making the hospital’s contact information the most pertinent in a health-related emergency connected with pesticide storage.
