Whether utilized in physical support or hot zone entry, the equipment used in mitigating hazardous materials incidents has advanced over the years. Portable decontamination units equipped for ambulatory and non-ambulatory patients make the hazmat scene safer by providing immediate care and rehab for entry teams and victims leaving the hot zone.
During initial incident analysis, chemical information entered into computer programs calculates hazard levels, flash points and toxic atmospheric movements based on chemical properties such as vapor pressure and viscosity, in concert with temperature and geography.
This material assists officers on scene and provides vital information for prediction. NFPA Edition 4. There are mission specific Operations Level Competencies. The station desk shall ensure that the following notifications are made:. Emergency Operations Bureau EOB shall ensure that the following units are notified and will coordinate their response as necessary:.
SEB will coordinate delivery of this cached equipment to the location when necessary. Each station PPE cache will also contain 12 replacement respirator canisters so that squad personnel who use their issued canister will immediately have functional respiratory protection after their mission is complete. Personnel wearing PPE will be monitored for heat stress and may be required to re- enter the warm zone to complete their missions. Suits, overboots, and respirator mask canisters shall be disposed of after each entry.
The respirator mask may be decontaminated and used again. When decontaminated, the respirator mask will be returned to the individual to whom it was issued. The decontamination and protection operation requires four squads. Each squad shall be designated numerically one through four and shall perform specific duties as described below:. PARS Public.

CBRN agents come in many forms and have different effects: Chemical — Chemical agents are generally liquids, often aerosolized, and most have immediate effects or are delayed for a few hours.
Many chemical agents have a unique odor and color. Biological — Biological agents often have no odor or color and can be either in liquid or powder form. The effects from a biological agent are usually delayed, often for days.
Radiological — A radiological dispersal device RDD is a conventional explosive dispersing radiological sources. Radiation cannot be seen, smelled, felt, or tasted. Nuclear — A nuclear weapon is a device that releases nuclear energy in an explosive manner as the result of nuclear chain reactions involving the fission or fusion or both, of atomic nuclei. Prior Knowledge What the majority of HazMat incidents have also had in common and based on the assumption that the entity concerned complies with all applicable laws is that those charged with first response have had some prior knowledge of the potential hazard that they are about to encounter.
Implications for first responders In all, twenty-one people received medical treatment after falling ill following the poisoning of Sergei Skripal and his daughter Yulia in March this year - among them were several police officers and paramedics who were some of the first on the scene.
