|
45,000 gallons
|
|
|
Rail tank cars can hold up to ______ gallons
|
45,000 gallons
|
|
|
What would a horizontal tank with rounded ends commonly hold?
|
liquid petroleum gas (LPG), anhydrous ammonia, compressed natural gas (CNG), chlorine
|
|
|
What are three main types of bulk transport?
|
• Rail
• Cargo (trucking) • Intermodal (containers designed to be transported by rail, truck, and ship) |
|
|
What is the most damaging kind of radiation?
|
ionizing radiation
|
|
|
What does a highlighted entry in the ERG (yellow or blue section) indicate?
|
That the material is toxic by inhalation and the user should immediately consult the green section for initial isolation and protective action distances. (Quick evacuation needed!)
|
|
|
What kinds of information does a monitoring device provide?
|
kind of material, quantity, and/or concentration of hazmat
|
|
|
What are the primary types of monitoring devices used at hazmat incidents?
|
• CGIs (Combustible Gas Indicators)
• pH papers • radiation detectors • detector tubes |
|
|
What do GGIs monitor?
|
Combustible Gas Indicators monitor
• concentration of a gas in the air • percentage of the LEL of the gas • parts per million of the gas in air |
|
|
What materials does a four-gas monitor check for?
|
• combustible gases - hexane or pentane
• oxygen • carbon monoxide • hydrogen sulfide |
|
|
What do indicator papers such as pH papers generally check?
|
Indicator papers indicate specific hazards such as oxidizers, hydrogen sulfides, and peroxides. Some can now indicate biohazards such as anthrax. pH papers indicate alkaline or acid levels.
|
|
|
What do Geiger counters indicate?
|
Levels of alpha, beta, and gamma radiation present, as indicated by the number of ions present.
|
|
|
What is a personal dosimeter?
|
Device worn to measure and identify a person's exposure to a particular radiation.
|
|
|
What is a detection tube and how does it work?
|
A detection tube is a glass tube filled with a substance that changes color when a particular gas or vapor comes into contact with it. Most useful when a specific chemical is suspected.
|
|
|
What are some drawbacks to detection tubes?
|
• require a pump to draw in vapors
• takes time to show results • tubes have a shelf life |
|
|
What are strategic goals at a hazmat incident?
|
Broad statements of what must be done. (The decision of whether to approach the incident offensively or defensively, for instance.)
|
|
|
What acronym describes an operational level responder's essential responsibilities at a hazmat incident?
|
S.I.N.
Safety (self, others, public) Isolate (defensively) Notify (emergency responders as well as those in harm's way) |
|
|
What are the hazard control zones?
|
Hot (hazmat entry teams only, in appropriate PPE)
Warm (decon corridor) Cold (no PPE req'd, air must still be monitored) |
|
|
What reference helps hazmat responders identify hazardous materials and the initial actions they must take to mitigate their effects?
|
Emergency Response Guidebook
|
|
|
Shelter in place is a form of rescue. TRUE or FALSE?
|
True
|
