Chapter 3 Flashcards
(41 cards)
Toxic Inhalation Hazard (TIH)
Volatile liquid or gas known to be a severe hazard to human health during transportation.
Polymerization
Chemical reactions in which two or more molecules chemically combine to form larger molecules; this reaction can often be violent.
Initial Isolation Distance
Distance within which all persons are considered for evacuation in all directions from a hazardous materials incident.
Initial Isolation Zone
Circular zone, with a radius equivalent to the initial isolation distance, within which persons may be exposed to dangerous concentrations upwind of the source and may be exposed to life-threatening concentrations downwind of the source.
Street Clothes
Clothing that is anything other than chemical protective clothing of structural firefighters’ protective clothing, including work uniforms and ordinary civilian clothing.
Structural Firefighters’ Protective Clothing
General term for the equipment worn by fire and emergency services responders; includes helmets, coats, pants, boots, eye protection, gloves, protective hoods, self-contained breathing apparatus (SCBA), and personal alert safety system (PASS) devices.
Self-Contained Breathing Apparatus (SCBA)
Respirator worn by the user that supplies a breathable atmosphere that is either carried in or generated by the apparatus and is independent of the ambient atmosphere. Respiratory protection is worn in all atmospheres that are considered to be immediately Dangerous to Life and Health (IDLH). Also known as Air Mask or Air Pack.
Chemical Protective Clothing (CPC)
Clothing designed to shield or isolate individuals from the chemical, physical, and biological hazards that may be encountered during operations involving hazardous materials.
Evacuation
Controlled process of leaving or being removed from a potentially hazardous location, typically involving relocating people from an area of danger or potential risk to a safer place.
Decontamination
Process of removing a hazardous foreign substance from a person, clothing, or area. Also known as Decon.
Cross Contamination
Contamination of people, equipment, or the environment outside the hot zone without contacting the primary source of contamination. Also known as Secondary Contamination.
Protective Action Distance
Downwind distance from a hazardous materials incident within which protective actions should be implemented.
Isolation Perimeter
Outer boundary of an incident that is controlled to prevent entrance by the public or unauthorized persons.
Defending in Place
Taking offensive action to protect persons in immediate danger at hazmat incidents.
Sheltering in Place
Having occupants remain in a structure or vehicle in order to provide protection from a rapidly approaching hazard, such as a fire or hazardous gas cloud. Opposite of evacuation. Also known as a Protection-in-Place, Sheltering, and Taking Refuge.
Incidental Release
Spill or release of a hazardous material where the substance can be absorbed, neutralized, or otherwise controlled at the time of release by employees in the immediate release area, or by maintenance personnel who are not considered to be emergency responders.
Using the four digit ID number or the chemical name allows
Responders to locate the most specific initial action guide
The ERG yellow border pages provide a
Four digit UN/NAID number index list in numerical order
The blue bordered pages of the ERG provide
An index of dangerous goods in alphabetical order by material name
The books orange bordered section is
The most useful because it provides safety recommendations and general hazards information
Left hand page lists
Potential hazards and public safety information
The right hand page provides
Emergency response information
Each guide is designed to cover a
Group of materials that possess similar chemical and toxicological characteristics
The potential hazards section addresses to hazards types under separate headers
Health hazards and fire or explosion hazards. The highest potential hazards is list first
