III.Terminology and Classification
  • A.The Incident Commander is the ranking fire official at the scene of a haz-mat incident and will exercise overall command of the incident.
  • B.A hazardous material is a substance in quantity and form which may pose an unreasonable risk to health, safety or property and which has been officially designated a hazardous material pursuant to the "Hazardous Materials Transportation Act" (49 U.S.C. 5101).
  • C.There are three systems for the identification of hazardous materials. The first is the National Fire Protection Association (NFPA) 704M sign, which may be used at fixed-site buildings and storage tanks. The second is the Hazardous Material Information System (HMIS) which may be used on storage vessels and containers. The third system is the U.S. Department of Transportation (DOT) system, which is used during the transportation of hazardous materials by highway, rail, air, and vessel.
  • D.NFPA and HMIS Systems
    • 1.The NFPA and HMIS systems use numbers and colors to identify and rate risks. There are four categories and five levels of risk. They are:
      • hazard (BLUE COLOR)
        • (1)Level 0 - normal material
        • (2)Level 1- slightly hazardous
        • (3)Level 2- hazardous
        • (4)Level 3- extreme danger
        • (5)Level 4- deadly
      • hazard (RED COLOR)
        • (1)Level 0 - will not burn
        • (2)Level 1 - must be preheated to burn (flash point above 200° F)
        • (3)Level 2 - ignites when moderately heated (flash point: between 100° F and 200° F)
        • (4)Level 3 - ignites at normal temperatures (flash point: below 100° F)
        • (5)Level 4 - extremely flammable (flash point: below 73° F)
      • c.reactivity (YELLOW COLOR)
        • (1)Level 0 - stable
        • (2)Level 1 - unstable if heated
        • (3)Level 2 - violent chemical change
        • (4)Level 3- shock and heat may detonate
        • (5)Level 4 - may detonate
      • d.specific hazard (WHITE COLOR)
  • E.DOT System
    • 1.Several thousand substances have been officially classified as hazardous materials, each of these materials has been assigned:
      • a.a unique 4-digit hazard identification number known as the United Nations (UN)/North American (NA) number; and
      • b.a classification number. There are nine classifications for hazardous materials. They are:
        • (1)Class 1 - Explosives
        • (2)Class 2 - Gases
        • (3)Class 3 - Flammable and Combustible Liquids
        • (4)Class 4 - Flammable Solids

      • a.The UN/NA number may be displayed in the center of the placard.
      • b.The classification number will be displayed in the bottom center of the placard.
      • c.The Dangerous placard may be displayed in lieu of individual placards whenever two or more classes of hazardous material are shipped together.

1. -
An incident involving exposure or potential exposure to any substance which, due to its nature or condition, poses or may pose an unreasonable risk to health, safety, or the environment, commonly referred to as a haz-mat incident. The CFD designates three classifications for all haz-mat incidents:
  • A.LEVEL I - The minimum initial response by the CFD's Hazardous Incident Team to any suspected or potential haz-mat incident. The primary focus is to investigate and/or mitigate incidents involving materials with minor potential impact.
  • B.LEVEL II - A confirmed incident involving a larger quantity of material with a moderate or high potential impact; or an incident which requires protective clothing; or an incident which requires evacuation of the surrounding area.
  • C.LEVEL III - An extensive incident which may require additional manpower, more resources than are normally deployed with the CFD Hazardous Incident Team Task Force, and/or involve an expanded evacuation area.
2. -
Responsible for the overall response to the incident, including the use of resources, development of strategies, and incident operations.
  • A.(Active Shooter Incident) The on-site Department member in overall command of the incident who is responsible for the implementation of the Active Shooter Incident Plan.
  • B.(Critical Incident) The highest-ranking on-site Department member responsible for the Chicago Police Department's overall response to a critical incident.
  • C.(Haz-mat) The highest ranking fire official at the scene of a haz-mat incident.
3. -
A command post can be devised for various types of incidents:
  • A.(SWAT Incident/Critical Incident/Active Shooter Incident) A secure position within the outer perimeter from which the Incident Commander directs operations.
  • B.(Hazardous Material Incident (Haz-Mat)) A secure position outside the restricted area from which the highest ranking on-scene Department member directs police operations, generally adjacent to the Chicago Fire Department (CFD) Command Van. The highest ranking on-scene Department member, if a Bureau of Patrol Area Deputy Chief, Street Deputy, or above, may authorize the use of the Department's Mobile Command Post when deemed appropriate and available.
4. -
  • A.(SWAT/Critical Incidents) A secure location where all responding units will report for briefing, assignment, and equipment and a location designated for use as a stand-by location for personnel not actually committed to responsibilities at the incident. The manager whose primary function is to provide intelligence and direction to responding units, is designated by the Incident Commander.
  • B.(Hazardous Material Incident (Haz-Mat)) A location designated for use as a stand-by location for personnel not actually committed to responsibilities at the incident.
5. -
  • A.(Crime Scene) The area of a crime scene extending large enough for field personnel to conduct a thorough investigation. This area will be secured with yellow crime scene barrier tape. The outer perimeter will encompass the inner perimeter.
  • B.(General/SWAT Incident) A peripheral control area surrounding the inner perimeter, providing a safe zone for access to the inner perimeter as well as defining the limit of access by unauthorized persons.
6. -
  • A.(Crime Scene) The immediate area within the outer perimeter of a crime scene where evidentiary material is likely to be collected. This area will be secured with red crime scene barrier tape, imprinted with the legend "DO NOT ENTER" or "DANGER - DO NOT ENTER".
  • B.(General Incident) The immediate area of containment as designated by the incident commander.
  • C.(Special Weapons and Tactics (SWAT) Incidents) The immediate area of containment as designated by the incident commander. This area is initially manned by responding beat personnel until relieved by members of the containment team.
