Detailed Recommendations for Enclosure Maintenance

Routinely inspect and clean roof and gutters to make sure they are draining properly.

Promptly repair roof or plumbing leaks.

Regularly inspect walls and foundations, especially all utility entrance seals (e.g., phone, water, electric, cable) for cracks and repair promptly if found.

Insulate cold pipes to prevent condensation.

Promptly remove wet ceiling tiles and wall panels.

Seal rusted surfaces to minimize emissions of airborne particulates using least toxic low-VOC sealant.

Include proper seal of the building in commissioning and re-commissioning programs for the building.

Remove excess water from carpeting damaged by clean water and quickly dry it to avoid mold buildup. Do not use disinfectants or moldicides (other than hydrogen peroxide-based ones). Instead, utilize a steam extraction carpet cleaning system with a hydrogen peroxide-based cleaner/disinfectant. Inspect carpet after it is completely dried to ensure there is no mold or mildew. Those with asthma or chemical sensitivities should be removed from areas where there is wet carpeting. Remove carpeting if it has been wet longer than 24 hours.

Immediately remove and do not re-use any wet carpeting that has been contaminated with sewer water, heavy dirt and soils, or toxic chemicals.

Seal rusted surfaces with a least toxic low VOC sealant to minimize emissions of airborne particles.

Include proper seal of the building in commissioning and re-commissioning programs for the building.
