What type of containment does the EPA recommend for areas with 35 ft.² of affected surface area?

1. Plywood barriers with lockable access

2. Polyethylene sheeting from ceiling to floor

3. Metal shutters for isolation

4. Fire-resistant curtains

The correct answer is: Polyethylene sheeting from ceiling to floor

The correct choice for the type of containment recommended by the EPA for areas with 35 square feet of affected surface area is the use of polyethylene sheeting from ceiling to floor. This requirement is in alignment with the EPA's guidelines for effective containment during mold remediation. Polyethylene sheeting serves as a suitable barrier because it is both flexible and durable, creating a sealed environment that helps prevent the spread of mold spores and dust into unaffected areas. By extending from the ceiling to the floor, the sheeting establishes a full enclosure, which is essential to maintaining a controlled space during the remediation process. The use of this material minimizes the risk of cross-contamination and ensures that safety protocols are followed effectively. Other methods mentioned, such as plywood barriers or metal shutters, may not provide the same level of airtight containment. Fire-resistant curtains do not effectively prevent the dispersal of mold spores and may not meet the necessary criteria for creating a controlled environment in a mold remediation scenario.
