CHICAGO — Occupants with multiple chemical sensitivity (MCS), asthma, or other chemical sensitivities can be severely affected by the chemicals used in restoration work — including cleaning products, adhesives, coatings, and antimicrobial treatments. Here is how restoration contractors can minimize chemical exposure for sensitive occupants.
The first step is communication. Contractors should ask about chemical sensitivities at the beginning of every project and document any sensitivities reported by occupants. This information should be shared with all subcontractors and should inform the selection of products and work practices throughout the project.
Product selection is critical for projects involving sensitive occupants. Contractors should select low-VOC or zero-VOC versions of cleaning products, adhesives, and coatings wherever possible. Many manufacturers now offer low-VOC versions of their standard products that perform comparably to conventional products.
Ventilation is the most effective engineering control for reducing chemical vapor exposure in occupied buildings. Contractors should maximize ventilation during and after the application of any chemical products, using portable fans and opening windows and doors to dilute and exhaust chemical vapors.
Occupants with severe chemical sensitivities may need to vacate the premises during restoration work and for a period afterward while chemical vapors dissipate. Contractors should advise sensitive occupants to consult with their physician about the appropriate precautions for their specific situation and should provide information about the products being used to facilitate that consultation.
