Firewater contains many hazardous substances that result from combustion, which can turn safe materials into toxic, polluting and environmentally damaging substances. One of the recognized techniques is to contain the firewater in the drainage system using pneumatic bladders or lockable non-return valves, which can be activated automatically or manually.įirewater containment is the process of containing the run-off from fighting fires. Managing firewater frequently requires that the water be contained on the site until removed from a specialized treat statement. Releasing contaminated firewater into a river, lake or other body that supplies drinking water may render the untreated supply unsuitable for drinking or food preparation. Premises containing quantities of plastics can also cause severe problems because of the taste and odor imparted to the firewater.

Certain premises, including farms and the chemical industry, pose special risks because of the types of materials present. This firewater contains materials present in the building and also contains dissolved and particulate materials from combustion processes and materials generated through quenching.įirewater can be particularly polluting when the building or site being extinguished itself contains potentially polluting materials such as pesticides, organic and inorganic chemical reagents, fertilizers, etc. In many firefighting situations, large quantities of water remain after the fire has been extinguished. In many cases, it is a highly polluting material and requires special care in its disposal.

Firewater refers to water that has been used in firefighting and requires disposal.
