Good Operations And Maintenance Prevent Mold
Concerns about health risks and potential liability have made mold a hot-button issue for many facility executives. Here are some basic good operating practices to help prevent mold and moisture problems:
- Minimize water used in mopping activities to prevent leaving excessive amounts of water along the baseboards at the edges of the floor.
- Check for and immediately address spills and potential water leaks.
- Dry any damp areas and any other visibly moist areas, including condensation on windows and windowsills.
- Clean bathroom areas routinely to reduce or prevent mildew growth.
- Keep shower curtains open after cleaning to help ventilate the area.
- Routinely check the caulking around showers, bathtubs and sinks for cracks or shrinkage. Re-caulk as necessary.
- Routinely check for leaks at plumbing fixtures. Repair leaks and dry the area immediately.
- Routinely check ceilings, walls and floors for discoloration or water stains. These potential indicators of water leaks should be immediately reported to the appropriate party.
- Keep return air vents clear of furniture for proper airflow.
- Close all windows and doors, especially during periods of inclement weather.
- Do not over-water indoor plants.
- Check emergency overflow pans for signs of water.
- Check plumbing and HVAC system pipes for signs of leakage.
- Routinely inspect the insulation around the ductwork for damage or moisture. If a problem is detected, notify an HVAC professional for inspection and repairs.
- Routinely check exterior walls, skylights, windows and sliding doors for discoloration or water stains. Note any unusual odors around the envelope of the building.
- Routinely inspect the integrity of the weather-stripping and its seal around windows, skylights and sliding doors. Replace as needed.
- Observe balconies or outdoor gardens above occupied areas (such as “green” roofs) during periods of wet weather. Note any areas of water accumulation and report them to the appropriate party.
