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, even to high levels, is extremely low.

What should I do with food left in my apartment? The power outage in much of lower Manhattan may have caused refrigerated and frozen food to spoil. Raw or cooked meat, poultry and seafood, milk and milk-containing products, eggs, mayonnaise and creamy dressings, and cooked foods should be thrown out if power was out for two or more hours. Frozen foods that have thawed should be thrown away. Do not re-freeze thawed food.

Throw away any food that may have been contaminated with dust, except for food in cans, jars, or containers with tight-fitting lids. Wash cans and jars with water and wipe it clean. When it comes to food left in your building, if in doubt, throw it out.

. How should I clean the dust in my apartment when I move back in ? 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. Where dust is thick, you can directly wet the dust with water, and remove it with wet rags and mops. Dirty rags can be rinsed under running water, being careful to not le^e dust in the sink to dry. When done, used rags and mops should be put in plastic bags while they are still wet and bags should be sealed and discarded. Cloth rags should be washed separately from other laundry. Wash heavily soiled or dusty clothing or linens twice. Remove lint from washing machines and filters in the dryers with each laundry load. Rags should not be allowed to dry out before bagging and disposal or washing.

To reduce dust recirculation, the Health Department recommends using HEPA (high efficiency particulate air) filtration vacuums when cleaning up apartments, if possible. If a HEPA vacuiun is not available, it is recommended that either HEPA bags or dust allergen bags be used with your regular vacuum. If these options are not available, wetting down the dust and removing it as described above is recommended.

Carpets and upholstery can be shampooed and then vacuumed.

• If your apartment is very dusty. youc^Eouldjwash or HEPA vacuum your curtains. H curtains need to be taken down, take them down slowly to keep dust from circulating in the air. • To clean plants, rinse leaves with water. Pets can be washed with running water from a hose or faucet; their paws should be wiped to avoid tracking dust inside the home.

How can I remove dustfrom the air? Air purifiers may help reduce indoor dust levels. HEPA air purifiers are superior to other models in filtering the smallest particles. Air purifiers are only useful for removing dust from the air. They will not remove dust already deposited on floors, shelves, upholstery or rugs. Keep windows closed when using an air purifier.

Additional recommendations include:

• Keep outdoor dust from entering the home; • Keep windows closed; • Set the air conditioner to re-circulate air (closed vents), and clean or change the filter frequently; • Remove shoes before entering the home for several days (once you first make sure there is no broken glass) • Avoid sweeping or other outdoor maintenance.
