Page Content: Persons entering areas and buildings subject to flooding face a variety of potential hazards, including but not limited to electrical hazards, structural hazards, displacement of wildlife, exposure to chemicals and sewage in contaminated floodwater, and mold growth from water-impacted building materials. First and foremost, life safety issues such as avoiding electrical shock and carbon monoxide poisoning must be considered before any cleanup or response is initiated.


General guidance on some of these hazards for the home and business owner is provided in the resources identified below. However, the American Industrial Hygiene Association (AIHA) strongly recommends that cleanup of hazardous materials be performed or overseen by professionals knowledgeable about the hazards and methods to protect occupants and the environment. AIHA members are health and safety professionals dedicated to protecting worker and public health. To reach out to AIHA safety and health consultants for professional assistance beyond these guidelines, a consultants list is available

An AIHA guidance document published in 2017, "Health and Safety Issues in Natural Disasters" (PDF), provides consumers and industrial hygienists a list of resources for addressing potential hazards during and after floods, tornados, and wildfires. The document is intended to enable recovery efforts while minimizing potential exposures to hazardous materials and conditions.

Before Entering Your Home

Hazards in and around flooded buildings include risk of structural collapse, electrical hazards, sewage contamination, trip and fall injury hazards, fire and explosion hazards where natural gas or bottled gas are present, loose or broken gas piping and gas leaks, and other hazards. Guidance for preparing to enter and entering your home may be found at these resources:

Hazardous Materials

Hazardous materials and conditions may be present as a result of damaged building materials containing lead or asbestos, sewage contaminated items, or hazardous materials such as chemicals or cleaning products present in floodwater. Heat and cold stress may be present when working long hours. Fire and carbon monoxide poisoning from combustion sources may also be a concern. Here are some useful resources to recognize and address these kinds of hazards:

Mold and Other Microbial Growth

Wet building materials and contents should be dried as soon as possible (preferably within 24–48 hours) to prevent mold growth. If significant mold or other sewage contamination has occurred, however, it is recommended that business and homeowners seek professional guidance before attempting to clean large amounts of contaminated materials. Industrial hygienists and other safety and health professionals can anticipate health and safety concerns and design solutions to prevent exposures using guidelines established by governmental agencies and institutions, such as the Institute of Inspection Cleaning and Restoration Certification.
