Planning for disaster debris:
Communities should plan ahead to handle exceptionally large amounts of disaster debris from damaged or destroyed buildings, supplies, trees or other green waste, carcasses, or other materials.
Disposal problems can result from types or amounts of debris but also from hazardous or toxic substances in the debris that can contaminate air, water, land, and food if not handled properly. Read more about disaster debris planning.
Recover after a tornado
People get sick or die each year from carbon monoxide or "CO" poisoning due to unsafe use of generators.
- ALERT: Generator exhaust is toxic. Always put generators outside well away from doors, windows, and vents. Never use a generator inside homes, garages, crawlspaces, sheds, or similar areas. Carbon monoxide (CO) is deadly, can build up quickly, and linger for hours. More information.

Disaster debris:
How a community manages massive amounts of disaster debris depends on the debris and any waste management options available. Burying or burning may not be acceptable unless permission or a waiver has been granted, because of the side effects of smoke and fire from burning, and potential water and soil contamination. Typical methods of recycling and solid waste disposal in sanitary landfills often cannot be applied to disaster debris because of the large volume of waste and reluctance to overburden existing disposal capacity. More information on disaster debris.
Renovation and rebuilding
Lead-safe work: By law, contractors need to use lead-safe work practices on emergency renovations on homes or buildings built before 1978. Activities such as sanding, cutting, and demolition can create lead-based paint hazards. Lead-contaminated dust is harmful to adults, particularly pregnant women, and children.
- Important information about lead-safe clean-up and renovation
Asbestos: Anyone working on demolition, removal, and cleanup of building debris needs be aware of any asbestos and to handle asbestos materials properly. People exposed to asbestos dust can develop serious lung health problems including asbestosis, lung cancer and mesothelioma. Although the use of asbestos has dramatically decreased in recent years, it is still found in many residential and commercial buildings and can pose a serious health risk.
