MDARD Michigan Core Pesticide Applicator Practice Exam

Is it sufficient to verbally warn workers of pesticide applications without posting signage?

1. Yes, oral warnings are sufficient

2. No, signage must also be posted

3. Only for minor applications

4. Only at night

The correct answer is: No, signage must also be posted

Posting signage in addition to providing verbal warnings is vital for ensuring worker safety during pesticide applications. Signage serves as a clear, visible reminder of the potential hazards in the area and communicates important information regarding the timing of applications, re-entry intervals, and the nature of the pesticides used. The rationale behind requiring signage is rooted in the need for consistent and easily accessible information regarding pesticide exposure. Verbal warnings may not be heard or may be forgotten by workers, especially in noisy environments or if workers are not present at the time of the verbal warning. Signage provides a permanent, reliable method of communication that remains in place until it is safe for workers to return. This approach helps to minimize the risk of unintentional exposure to pesticides, enforcing the standard practices for workplace safety. This requirement is particularly important in agricultural and landscaping settings, where workers may be present in areas where pesticides have been applied or are about to be applied. Reinforcing safety measures through both visual and verbal communications is essential for comprehensive risk management.
