Question: 1 / 400

The entrance of a containment enclosure must be covered by how many flaps?

One flap

Two flaps

In a containment enclosure, the entrance typically requires two flaps to ensure effective containment of airborne particles and to minimize exposure to mold spores during the entry and exit process. The dual flap design creates a more efficient barrier which helps to maintain negative pressure within the contained area. When a worker enters through the first flap, it prevents external air (and any potential contaminants) from rushing in. As the first flap closes, the second flap can then be opened, allowing for a more controlled environment that limits the spread of mold-related particles. This design is a critical component in mold remediation practices to effectively contain and manage the work area, ensuring safety and compliance with health standards.
