When should HVAC systems be checked during a trauma scene cleanup?

The HVAC systems should be checked before the cleaning process begins and after to ensure they are not contaminated. This approach is crucial for several reasons.

First, examining the HVAC system prior to starting the cleanup helps identify any potential contamination that could affect air quality and spread pathogens or contaminants throughout the space. In trauma scene cleanup, there may be biological hazards, odors, or other harmful substances that could circulate via the HVAC system if not properly addressed.

After the cleaning, it is just as important to reassess the HVAC system to confirm that it is free from any residual contaminants and that the air quality has been restored to a safe level for occupants returning to the space. This double-check ensures that any cleaning efforts are fully effective and that no harmful materials remain within the ventilation system, thereby protecting the health of individuals who may occupy the area in the future.

This thorough approach emphasizes the importance of priorities in trauma scene cleanup—ensuring safety and health above all else.
