Hazardous Materials Initial Incident Response Flashcards
The area with actual or potential contamination and the highest potential for exposure to hazardous substances.
Exclusion zone (hot zone)
The transition area between the exclusion and support zones. This area is where responders enter and exit the exclusion zone and where decontamination activities should take place.
Contamination reduction zone (warm zone)
The area that is free from contamination that should be safely used as a planning and staging area.
Support zone (cold zone)
Whenever practicable, the first arriving Elyria Fire Department unit should approach the scene from upwind and uphill and stage at a location estimated to be in the cold zone. Contact Dispatch and provide the following information:
Unit on-scene
Initial scene size-up
…….which should be in the cold zone
Unit assuming incident command (IC)
Primary (Level 1) staging location,
Perform or direct another member to perform a 360 assessment and report the results to the IC. Whenever available, personnel should use air monitors, such as four-gas monitors, to assist in determining levels of contamination. For hazardous materials response, the 360 assessment report should include, but not be limited to:
Any leaking of liquids
Any venting of gases or vapors
…….
Possible victims
Identification of the hazardous material
The Fire Chief or authorized designee shall have the responsibility to develop and maintain a …….that identifies the department’s operational response to hazardous materials incidents that include (29 CFR 1910.120; ORC § 4167.07; OAC § 4123:1-21-07; OAC § 4167-3-03):
written plan
Apparatus should be positioned in the …….and, whenever practicable, upwind, uphill and upstream of any vapor cloud or spill.
cold zone
Personnel should engage only in operations in relation to their …….and only when wearing PPE appropriate to the level of the incident.
level of training
The primary objectives of a hazardous materials response include, but may not be limited to:
……. the hazardous material.
Evacuating the contaminated area.
Denying entry to the contaminated area.
Isolating, confining and containing
The primary objectives of a hazardous materials response include, but may not be limited to:
Isolating, confining and containing the hazardous material.
…… the contaminated area.
Denying entry to the contaminated area.
Evacuating
The primary objectives of a hazardous materials response include, but may not be limited to:
Isolating, confining and containing the hazardous material.
Evacuating the contaminated area.
……. to the contaminated area.
Denying entry
Personnel should assume that any unknown or unidentified substance is a ……. until confirmed otherwise.
hazardous material
As soon as it is practicable, the IC should confirm operational……. zones and relocate staging locations, the command post and personnel accordingly.
hot, warm and cold
When available, personnel should use air monitors, such as…… monitors, to continually read the scene contamination levels.
four-gas
Whenever practicable, the IC should have at least one ……. ambulance on-scene and available for treatment and transport before personnel enter the hot zone.
advance life support
The IC should evaluate responding personnel’s level of training in relation to the hazard. Hazardous materials mitigation activities should not exceed the ……. and PPE required to contain and/or mitigate the hazard.
level of training
These incidents are relatively small and can usually be handled using defensive actions by initial responding personnel wearing structural firefighting PPE. These incidents have no environmental impact and pose little threat to the public.
Level I
Fuel spills of less than 20 gallons that have not entered or threatened to enter storm drains or waterways that can be contained by use of dikes, diversion and collection.
Level I
Natural gas or propane leak at a single-family residence with no explosion, fire or injuries that can be mitigated by shutting off the gas supply and venting the residence or through use of controlled tank venting or plugs.
Level I
Requests for investigation of an unknown odor that finds no hazardous materials present.
Level I
Carbon monoxide calls.
Level I
These incidents should be considered as more complex than Level I incidents and may require offensive or defensive actions and evacuation. These incidents can pose a significant threat to the environment and public health and may require trained HAZMAT teams with specialized equipment and PPE.
Level II
Fuel spills or leaks of more than 20 gallons entering or threatening to enter storm drains or waterways. These incidents may require immediate containment measures and monitoring the spread of the hazard to determine downstream contamination or hazards.
Level II
A release of hazardous materials with the potential for explosion.
Level II
