Design restrooms with proper drainage to prevent standing water in sinks or on floors. New products or materials should be evaluated for emissions characteristics, life cycle duration, and toxicity. Select a low-VOC emitting paint that is free of lead and mercury. Schedule painting to occur when the area is unoccupied and allow time for paint odors to dissipate before occupants return to the area. Hard flooring, such as terrazzo, ceramic tile, and brick, is durable and easy to clean.
Hardwood flooring is preferable to laminate flooring, which contains formaldehyde.
Make sure the carpet does not contain liquid latex or a vinyl backing. Unroll flooring products and cushion in a well-ventilated location prior to installation. Install carpet only when the school building is not in use. Operate the HVAC system at normal temperature and highest possible outdoor air supply setting during installation and for at least 72 hours after installation is completed. When undertaking a school renovation project, it is important to evaluate the potential hazards of demolition.
