APPARATUS: A mobile piece of fire equipment such as a pumper, aerial, tender, automobile, etc. APPROVED: A method, equipment, procedure, practice, tool, etc., that is sanctioned, consented to, confirmed or accepted as good or satisfactory for a particular purpose or use by a person, or organization authorized to make such a judgment. BLOODBORNE PATHOGENS: Pathogenic microorganisms that are present in human blood and can cause disease in humans. These pathogens include, but are not limited to, hepatitis B virus (HBV), human immunodeficiency virus (HIV) and other potentially infectious materials (OPIM). CBRN: Chemical, biological, radiological and nuclear. CHRONIC HEALTH EFFECT: An adverse health effect resulting from long- term exposure to a substance. The term is also applied to a persistent (months, years or permanent) adverse health effect resulting from a short-term (acute) exposure. CLEANING: To make (something or someone) free of dirt, marks or mess, especially by washing, wiping or brushing. CONTAMINATED: The presence or the reasonably anticipated presence of materials foreign to the normal atmospheres, blood, hazardous waste or other potentially infectious materials on an item or surface. CONTAMINATION: The process of transferring a hazardous material from its source to people, animals, the environment or equipment, which may act as a carrier. DECONTAMINATION: The physical or chemical process of cleansing an object to remove contaminants such as microorganisms or hazardous materials, including chemicals, radioactive substances and infectious diseases. Decontamination is sometimes abbreviated as "Decon." Also prevents the spread of contamination to other persons or equipment. DISINFECTION: A procedure that inactivates virtually all recognized pathogenic microorganisms, but not necessarily all microbial forms (i.e., bacterial endospores) on inanimate objects. ENGINE (PUMPER): A piece of apparatus equipped with hose and a pump for the purpose of supplying water under pressure through hose lines. EXPOSURE OR EXPOSED: When an employee is subjected in the course of employment to a chemical that is a physical or health hazard, and includes potential (e.g., accidental or possible) exposure. “Subjected” in terms of health hazards includes any route of entry like inhalation, ingestion, skin contact or absorption (OSHA - 29 CFR 1910.1200). FIRE APPARATUS: A fire department emergency vehicle used for rescue, fire suppression or other specialized functions. FIRE DEPARTMENT FACILITY: Any building or area owned, operated, occupied or used by a fire department on a routine basis. GROSS DECONTAMINATION: The initial phase of the decontamination process during which the amount of surface contaminant is significantly reduced. HAZARD CONTROL ZONES: 1 COLD zone: The control zone of an incident that contains the command post and such other support functions as are deemed necessary to control the incident. 1 WARM zone: The control zone outside the hot zone where personnel and equipment undergo decontamination and the hot zone support takes place. 1 HOT zone: The control zone immediately surrounding the hazard area, which extends far enough to prevent adverse effects to personnel outside the zone. The hot zone is presenting the greatest risk to members and will often be classified as an IDLH atmosphere. HEALTH AND SAFETY OFFICER: The member of the fire department assigned and authorized as the administrator of the fire department health and safety program. IDLH: Immediately dangerous to life and health. Exposure to airborne contaminants that is likely to cause death or immediate or delayed permanent adverse health effects or prevent escape from such an environment. DEFINITIONS APPENDIX B 3 0
