Surfaces in the work area that could become contaminated should be covered with a secured plastic sheet(s) before remediation to contain dust/debris and prevent further contamination.Dust suppression methods, such as misting (not soaking) surfaces prior to remediation, Mold Abatement Regulations are recommended.

Contaminated materials that cannot be cleaned should be Mold Abatement Regulations removed from the building in a sealed impermeable plastic bag. These materials may be disposed of as ordinary waste.The work area and areas used by remediation workers for egress should be HEPA vacuumed and cleaned with a damp cloth or mop and a detergent solution.

All areas should be left dry and visibly free from contamination and debris. Level III: Large Isolated Areas(30 -100 square feet) - e.g., several wallboard panels. Industrial hygienists or other environmental health and Mold Abatement Regulations safety professionals with experience performing microbial investigations and/or mold remediation should be consulted prior to remediation activities to provide oversight for the project.

The following procedures may be implemented depending upon the severity of the contamination:It is recommended that personnel be trained in the handling of hazardous materials Mold Abatement Regulations and equipped with respiratory protection (e.g., N-95 disposable respirator).

Gloves and eye protection should be worn.Surfaces in the work area and Mold Abatement Regulations areas directly adjacent that could become decontaminated should be covered with a secured plastic sheet(s) before remediation to contain dust/ debris and prevent further contamination. Seal ventilation ducts/grills in the work area and areas directly adjacent with plastic sheeting.

The work area and areas directly adjacent should be unoccupied. Removing people from spaces near the work area is recommended for infants, Mold Abatement Regulations persons having undergone recent surgery, immunesuppressed people, or people with chronic inflammatory lung diseases. (e.g., asthma, hypersensitivity pneumonitis, and severe allergies).

Dust suppression methods, such as misting (not soaking) surfaces prior to mediation, Mold Abatement Regulations are recommended.
