Definition of a Hazardous Material Emergency: Releases of hazardous substances (Radioactive, Chemical, or Infectious Agents) that pose a significant threat to health and safety or that, by their very nature, require an emergency response regardless of the circumstances surrounding the release or the mitigating factors are emergency situations. The following definitions designate an emergency. 1. The situation is unclear to the person or discovering the emergency or accidental occurrences. 2. The situation requires evacuation of persons since it involves or poses a threat of: A. Fire, suspected fire, explosion or other imminent danger. B Conditions that is immediately dangerous to life and health (IDLH). Note: IDLH an atmosphere concentration of any toxic, corrosive, or asphyxiant substance that poses an immediate threat to life, would cause irreversible or delayed adverse health effects, or would interfere with a person's ability to escape from a dangerous atmosphere. (Hazwoper 408.1011a) C. High levels of exposure to hazardous substances. D. Chemicals, radioactive materials, or infectious agents could enter the air circulation system of the building. 3. The person(s) in the work area are uncertain they can handle the severity of the hazard with the personal protective equipment that has been provided and/or exposure could occur. Conversely, releases that do not pose significant safety or health to person(s) in the immediate vicinity or to the person(s) cleaning releases, and do not have the potential to become emergencies within a short time frame are not emergency situations. The following situations ARE NOT emergency situations: 1. The person causing or discovering the release understands the properties and can make an informed decision as the exposure level. 2. The release can be appropriately cleaned up by the lab personnel using proper spill clean up techniques. 3. The materials are limited in quantity, exposure potential, toxicity and present only minor safety or health hazards to persons in the immediate work area or those assigned to clean up. Appendix G 4. Incidental releases of hazardous substances that are routinely cleaned up be the
