Which individual must approve the use of certain hazardous products prior to application in schools?

The IPM Coordinator is responsible for overseeing Integrated Pest Management (IPM) practices within schools, which includes the use of hazardous products. This individual ensures that the products used are safe for students and staff and comply with relevant regulations and guidelines concerning safety and environmental protection. Part of their role is to evaluate the necessity and appropriateness of using certain hazardous materials, making their approval critical prior to any application.

The other options, while they may have roles in the decision-making process or implementation, do not carry the same level of dedicated responsibility regarding the oversight of hazardous product usage in schools. The school principal may have general authority but typically relies on the expertise of the IPM Coordinator. A certified applicator is qualified to apply pesticides but does not necessarily make decisions about their usage within the school context. Likewise, requiring approval from all staff members would lead to a disorganized process and is not a feasible approach for managing pest control protocols safely and effectively.
