What are the health effects of asbestos?

Destruction of the World Trade Center buildings released large amounts of dust and ash, some of which contained trace amounts of asbestos. Based on the asbestos test results received thus far, the general public’s risk for any short or long term adverse health affects are very low. Residents who live near the affected area are not at risk of developing asbestos-related illness following the collapse of the World Trade Center buildings.

In general, asbestos-related lung disease general results only fi-om intense asbestos exposure experienced over a period of many years, primarily as a consequence of occupational exposures. The risk of developing an asbestos-related illness following an exposure of short duration is very low.

What measures are being taken to protect the rescue workers?

Rescue workers have been equipped with half-face masks, goggles, and protective clothing to reduce their exposure to dust and other particulate matter while working in the blast zone.

How can I clean up dusts in or near my home or office?

The best way to remove dust is to use a wet rag or wet mop. Sweeping with a dry broom is not recommended because it can make dust airborne again. Dirty rags should be put in plastic bags while they are still wet and bags should be sealed and discarded (cloth rags can be washed, see instructions below). Rags should not be allowed to dry out before bagging and disposal or washing. Because the dust particles are so small, standard vacuuming is not an efficient way to remove the dust. High efficiency vacuums, which are now widely available in stores, should be used to remove dust. Carpets and upholstery can be shampooed, then vacuumed.

Persons should shower to rinse off any dust from hair and skin. Dusty clothes should be washed separately from other clothing. Pets can be washed with running water from a hose or faucet; their paws should be wiped to avoid tracking dust inside the home. To clean plants, rinse leaves with water. Throw away any food that may have been contaminated with dust. Food in cans, jars or containers with tight-fitting lids do not need to be discarded. However, if there is dust present on the exterior of vacuum-sealed food containers, just wash the can or jar with water and wipe it clean. If in doubt, throw it out.

Air purifiers may help reduce indoor dust levels. High efficiency air purifiers are superior to other models in filtering the smallest particles. Air purifiers are only useful for removing dust fi-om the air. They will not remove dust already deposited on floors, shelves, upholstery or rugs. Keep windows closed when using an air purifier.
