Where should signs be posted to indicate a treated site?

• A. Only at the main entrance.
• B. At each point of entry, clearly visible from roads, sidewalks, driveways, doorways, alleys, and yards.
• C. Inside the treated area.
• D. No posting is required.

Answer: (B)

Posting signs at every entry point and making them clearly visible from approaches such as roads, sidewalks, driveways, doorways, alleys, and yards ensures anyone approaching the site is warned before entering. This coverage prevents people from accidentally stepping into a treated area through any access point, not just the main entrance. Placing signs only at one entrance can miss other ways in, and putting signs inside the treated area fails to warn people beforehand. Not posting at all is unsafe and typically not permitted. So the best practice is to place signs at each entry point where they can be seen from external routes, giving clear notice of the treatment and any access restrictions.
