What safety measures should be taken during the air duct cleaning process?

The selection of using personal protective equipment (PPE) and ensuring adequate ventilation is essential for safety during the air duct cleaning process. PPE, such as masks, goggles, and gloves, protects the technician from dust, debris, and potentially harmful contaminants that could be released during cleaning. Adequate ventilation is crucial to prevent the accumulation of airborne particles in the work area, ensuring that both the technician and any occupants remain safe from respiratory issues.

Other options do not fully address the comprehensive safety measures needed. Relying solely on gloves does not provide sufficient protection against all potential hazards encountered during the cleaning process. Turning off all HVAC systems may not always be necessary; while it is important to manage airflow and minimize the spread of contaminants, in some cases, selective operation of certain systems may be appropriate to control dust and debris dispersion. Using cleaning agents without PPE poses a significant risk since these substances can contain harsh chemicals that are harmful if inhaled or come into contact with skin. Hence, the correct choice emphasizes a holistic approach to safety that combines appropriate protective measures with environmental considerations.
