What must happen to the treated area when deodorizing?

When deodorizing an area affected by smoke or fire damage, it is critical that it be vacated by persons without respiratory protection. This practice ensures safety, as certain deodorizing agents may release fumes or particles that could be harmful when inhaled. By ensuring that those in the area are equipped with the appropriate protective gear, the risk of respiratory issues is minimized, allowing for a safer process.

In contrast, keeping the treated area open to air can be beneficial for circulating fresh air and facilitating the deodorizing process, but it does not directly address the safety concerns for individuals present in the space. Monitoring the area while deodorizing may occur, but it does not provide adequate assurance for human safety without respiratory protection. Sealing off the area may limit airflow and hinder the deodorization process, making it less effective overall.
