When possible, arrange for construction and remodeling activities to take place when the building is not occupied (nights, weekends, holiday breaks etc.). Provide notification to employees who are chemically sensitive prior to such activities so accommodation arrangements can be made. Plan to use non-toxic building products and practices during construction and remodeling. Use low/no odor paints and stains that emit low to no volatile organic compounds (VOCs) or are made of natural substances. Allow sufficient drying time and ventilation. When applicable, use air filtration devices such as portable air purifiers and vent filters to reduce exposure to dust. When purchasing office furniture, try to avoid pressed wood products, fabric covered products and plastics. New furniture tends to off-gas chemicals, such as formaldehyde, which can trigger MCS symptoms. Seek out products made of metal, untreated woods or leather. Arrange for the employee to relocate during construction activities or investigate working from home as an accommodation.
