Mitigation

The effort to reduce loss of life and property by lessening the impact of incidents. Mitigation includes any activities that prevent an emergency, reduce the chance of an emergency incident occurring, or reduce the damaging effects of unavoidable incidents. Mitigation activities take place both before emergency incidents (e.g., clearing brush to mitigate wildland fires), during, and after emergency incidents (e.g., containing a hazardous material spill, isolating a process).

Technique to eliminate or lessen the likelihood and/or consequence of a risk.
