Which storage precaution is recommended for herbicides?

• A. No signs required
• B. Signs posted with a locked door
• C. Signs posted on the outside, but door open
• D. No signage is needed

Answer: (B)

Posting warning signs on the outside of the herbicide storage area and keeping the door locked is the recommended precaution because it both warns people of the hazard and controls access. Signs clearly indicate that toxic pesticides are stored there, which helps prevent accidental exposure or improper handling, and a locked door stops unauthorized or untrained individuals from entering. This combination supports safety and regulatory expectations for pesticide storage.

Other approaches fall short because they either skip warning people about the hazard or fail to restrict access. No signs means people wouldn’t know a pesticide is present, increasing the chance of accidental contact or misuse. Signs on the outside while the door is left unlocked still allows easy entry, defeating the purpose of limiting exposure. And claiming that no signage is needed ignores basic safety obligations for storing hazardous chemicals.
