National Air Duct Cleaners Association (NADCA) Practice Test

A safety plan for duct cleaning is a formal plan that maps out how safety will be protected for both occupants and workers, outlining hazards, control measures, responsibilities, and procedures before work starts. It guides the crew on containment, dust control, proper work methods, and when and what PPE is needed, while also defining lockout/tagout procedures, electrical safety, access restrictions, and emergency actions. It also covers how to communicate with building occupants and coordinate with other trades to minimize disruption and exposure. This approach is why the plan is essential: it explicitly documents how risks will be mitigated, giving everyone a clear, shared set of safety expectations and steps to follow, which helps reduce risk and ensure compliance with NADCA guidelines and applicable codes. It’s important to recognize that a safety plan does not guarantee zero hazards, nor does it guarantee the lowest cost, and it does not remove the need for PPE; it instead defines how those risks will be managed and what protections are required.
