A disaster-impacted area or a damaged building or site is usually an unsafe environment for first responders. Therefore, before starting any on-site surveys or assessments the safety and security of the site must be ascertained. During the course of their work, the members of a damage assessment team may be exposed to potentially life-threatening hazards from broken, damaged, and unstable structures; contaminated materials and hazardous waste; electrical systems; and – in war zones – unexploded ordnance.
Because of these omnipresent dangers, the damage assessment teams should wear appropriate protective clothing, including a hard hat or helmet, safe shoes, protective gloves, and facemasks to protect themselves from dust, asbestos, and other pollutant inhalation. They should also carry first aid kits.
