Question: 1 / 400

What pressure should the containment area be kept under?

Positive pressure

Negative pressure

Keeping the containment area under negative pressure is essential during mold remediation to ensure that airborne spores and contaminants do not escape into the surrounding environment. When the containment area is under negative pressure, air is drawn into the containment from outside rather than allowing air to flow out. This minimizes the risk of spreading mold spores and other contaminants to areas that are not affected, thereby protecting the health of occupants and ensuring that the remediation process is effective.

Negative pressure is crucial in controlling airborne particles, especially in environments where mold is present. This method also allows for better management of ventilation, making sure that the work area remains isolated and safe for both the workers involved in the remediation and any inhabitants of the building.
