90 percent at a level belowground
Black powder smokeless powder and solid rocket fuel would be placarded as

Non pressure cargo tanks
Low pressure cargo tanks transport liquids that may have a —– than those products carried in their nonpressure counterparts
Higher vapor pressure
Which is a characteristic of most corrosive tanks?
Valves must be manually opened and closed because they do not have emergency shut off valves
Which type of cargo tank is round with flat ends and must be adequately insulated giving it a bulky appearance?
Cryogenic tanks
Which safety feature of railway tank cars offers an extra layer of puncture protection an the ends of the tansk?
Head shields
What safety feature prevents the loss of a tank car’s contents in the event of a derailment?
Skid protection
Which tank car fitting is the most obvious fitting found on most tank cars and plays an integral part in tank car identification?
Manways
What is the most common source of a leak on nonpressure tank cars?
Manways
Which railway tank cars have a cylindrical cross section with flat head and are typically manufactured as a tank within a tank?
Cryogenic tank cars
The two major types of frame construction used for intermodal tank containers are
Box type and beam type
Intermodal tanks for liquids and solid hazardous materials
may have top loading or bottom loading valves and are equipped with emergency remote shutoff devices
Emergency response plans carried by operators of tank vessels carrying petroleum products enter the US and canada identify and ensure the availability of
a company with pollution incident response capabilities in the area in which the vessel operates
Which type of marine vessel is typically a box shaped flat decked vessel that is not self propelled
Barge
Where must pipeline companies place markers?
At sufficient intervals along the pipeline to identify the pipes location
What information is included on pipeline markers in the US and Canada?
Info describing the transported commodity and the name and emergency telephone number on the carrier
In fixed facility containers what can help release container pressure there by preventing catastrophic failures?
Vacuum relief protection devices
Packaged of radioactive materials must be labeled:
on opposite sides with the distinctive warning label
SCBA must be worn during emergency operations at terrorist/hazmat incidents until which actions determines other options are acceptable?
Air monitoring and sampling
The Department of Homeland Security has adopted recommended standards for
Respiratory equipment that protect responders from hazards from materials that could be used in terrorist attacks
Self contained breathing apparatus is a
Atmosphere supplying respirator for which the user carries the breathing air supply
A self contained breathing apparatus unit consist of a facepiece, pressure regulator, harness assembly and
a compressed air cylinder
What is and end of service time indicator found on SCBA
A device that alerts the user that the respiratory protection equipment is about to reach its limit
Supplied air respirators
are certified for confined space hazardous materials but not fire fighting ops
Air purifying respirator are
Available in either powered or nonpowered designs
Do not use powered air purifying respirators in
Potentially explosive atmospheres
What is a difference between inherently flame resistant IFR and flame retardant FR?
IFR protective properties cannot be washed out of the material
Which EPS level of protection is composed of splash protecting garment and an air purifying device
LEVEL C
Which EPA level of protection is primarily used at incidents including highly toxic and corrosive gases?
Level A
Which typical ensemble worn by response personnel typically consists of ballistic protection and no respiratory protection
Law enforcement ensembles
What determines the PPE needed at a hazmat incident
A hazard assessment
Which in NOT a general selection factor in selecting PPA at hazardous materials incidents
Jurisdiction boundaries
What do responders need to take into account in order to choose protective clothing with appropriate level of chemical resistance
Permeation and degradation
Compromise of PPA from permeation occurs when
a chemical passes through the material
The most common observations of —are discoloration swelling loss of physical strength or deterioration
degradation
What is the heat illness in which the body’s heat regulating mechanism fails
Heat stroke
