Question: 1 / 400

During an inspection, what should an ASCS focus on when black particulates are observed coming from diffusers?

Condition of the ceiling tiles

Condition of the internal duct insulation

Focusing on the condition of the internal duct insulation is crucial when black particulates are observed coming from diffusers because this can indicate a potential source of contamination within the HVAC system. Black particulates could be a sign of microbial growth, particularly mold or mildew, which often thrives in damp or improperly insulated areas. If the internal insulation is damaged or compromised, it can release particles into the airstream, leading to air quality issues and health concerns.

Inspecting the internal duct insulation allows for the identification of any damage, mold growth, or other problems that could contribute to the presence of these contaminants. Addressing the condition of the internal duct insulation can be pivotal in preventing further contamination and ensuring the system operates efficiently and safely.
