Prior to making pesticide applications in non-residential public buildings, which action is required?

• A. A notice must be placed at entrances to the room or area to be treated
• B. A notice must be mailed to employees
• C. A notice must be posted only after treatment
• D. No notice is required

Answer: (A)

Communicate exposure risk by posting a warning before doing the treatment. In non-residential public buildings, the area to be treated must have a conspicuous notice placed at entrances so anyone entering or using the space is aware that a pesticide will be applied. This pre-treatment posting protects occupants, allows them to avoid or prepare for the exposure, and satisfies label directions and regulatory rules. Mailing notices to employees isn’t practical for targeting the specific area, posting after the treatment fails to warn people in advance, and saying no notice is required ignores safety and regulatory obligations.
