For example, among the aspects to consider is using the product with the lowest Health Hazard Rating that does not have any special ventilation recommendations. Store chemicals properly in an area not normally occupied by people, and mechanically vent the storage area directly to the outside of the building. Read and follow directions for use on the label. Do not mix any cleaning products unless directed on the product label. If the product is used inside the building, increase ventilation by opening a window and using exhaust fans.
Control exposures at the source before indoor air becomes contaminated.
A person's exposure to VOCs, particulates, and ozone can be decreased by installing a mechanical exhaust vent directly over a highly used piece of office equipment such as a large copier. A maintenance schedule for the office equipment should be closely followed. Generally, a well designed, maintained, and functioning air handling system can serve to dilute many of the potential pollutants within an office setting. Sometimes, merely opening windows can help. Filter the air before it is inhaled.
