Class 8

A

Corrosive materials

25
Q

Class 9

A

Miscellaneous hazardous materials/Products, substances or organisms

26
Q

Those that detonate are characterized by

A

destroying property and producing a shock wave that may injure or kill

27
Q

Those that deflagrate

A

Burn rapidly and are characterized by adding to the fire load and burning intensity

28
Q

gasoline is found in which class

A

Class 3 Flammable and Combustible liquids

29
Q

Calcium carbide

A

water reactive

30
Q

Oxidizing substances supply

A

their own oxygen to the burning process

31
Q

Peroxides are

A

very unstable when heated or improperly stored

32
Q

Fire fighter safety can be accomplished at hazardous materials incident often by

A

doing nothing or by taking defensive actions only, keeping away from the effects of the chemical

33
Q

To ensure the highest level of fire fighter safety

A

proper product identification and then notification of the hazmat team is necessary

34
Q

Three levels of risk associated with rescue at a hazardous materials incident are

A

Low Risk
Calculated Risk
Unacceptable Risk

35
Q

Low Risk category is based on Four assumptions

A
  1. The hazards are know and are not expected to increase
  2. The PPE available is appropriate to the task
  3. Responders are properly trained for the Task
  4. There is high probability of safe and successful outcome
36
Q

Calculated Risk

A

A calculated risk involves the same assumption as that made in the low risk model, with one exception- the degree of certainty that the hazards are not expected to increase ( the hazards may increase)

37
Q

Unacceptable Risk

A

An unacceptable risk has no chance of success. In this situation fire fighters should not be committed to entering locations containing the product. the risk associated with search and rescue significantly outweigh the potential gains

38
Q

Never should a gas fire be extinguished

A

if the gas supply cannot be stopped immediately after the fire is out

39
Q

Defensive actions

A

the tactical objective are designed to limit the area of impact or stop the forward spread of the material.

40
Q

The goals os confinement

A

The tactical objectives including damming, diking and retention

41
Q

For the goal of evacuation, two objectives must be considered. The first objective is

A

to notify those who must and can be moved. This can be accomplished though public address systems, the media local emergency broadcast networks and door to door canvassing.

42
Q

For the goal of evacuation, tow objectives must be considered. The second objective deals with

A

those who need protection or evacuation but cannot be moved for whatever reason. In case the objective is to shelter in place

43
Q

Fire fighters responding to a ship fire will probably find the

A

fire control plan (FCP) the most valuable resource available because it has most of the information the IC would need to fight a fire on the ship

44
Q

Items included in the Fire control plan (FCP)

A 
General layout of the ship
Dimensions
Locations of firefighting systems
Locations of the communication systems
Plans for each deck of the ship
45
Q

Much information on the cargo and position of the railcars can be found

A

on the consist or the wheel report

46
Q

Bulk storage facilities

Preplanning should cover all the routine preplanning subjects and in addition

A

list the columns of products
the physical and chemical hazards
the technical assistance available
the level of evacuation that might be required

47
Q

Low pressure tanks have different types of roofs

A

including cone roof
Floating roof
floating roof with geodesic dome
cover floating roof

48
Q

Pressurized tanks hold

A

gases that are liquefied or stored in bulk under pressure

49
Q

Bulk tanks are

A

generally steel constructed and may be closely laid out to one another in a tank farm arrangement.

50
Q

Crews should not be place in line

A

with the ends of tanks counting pressurized gases.

51
Q

Water should be applied in large quantities to the

A

vapor space of pressurized containers and to the sides below the liquid line of large liquid or non pressurized tanks

52
Q

The substation fire is usually a

A

Class b fire after the electricity has been shut down.
