Class 9
Miscellaneous hazardous materials/Products, substances or organisms
26
Those that detonate are characterized by
destroying property and producing a shock wave that may injure or kill
27
Those that deflagrate
Burn rapidly and are characterized by adding to the fire load and burning intensity
28
gasoline is found in which class
Class 3 Flammable and Combustible liquids
29
Calcium carbide
water reactive
30
Oxidizing substances supply
their own oxygen to the burning process
31
Peroxides are
very unstable when heated or improperly stored
32
Fire fighter safety can be accomplished at hazardous materials incident often by
doing nothing or by taking defensive actions only, keeping away from the effects of the chemical
33
To ensure the highest level of fire fighter safety
proper product identification and then notification of the hazmat team is necessary
34
Three levels of risk associated with rescue at a hazardous materials incident are
Low Risk
Calculated Risk
Unacceptable Risk
35
Low Risk category is based on Four assumptions
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
Calculated Risk
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
Unacceptable Risk
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
Never should a gas fire be extinguished
if the gas supply cannot be stopped immediately after the fire is out
39
Defensive actions
the tactical objective are designed to limit the area of impact or stop the forward spread of the material.
40
The goals os confinement
The tactical objectives including damming, diking and retention
41
For the goal of evacuation, two objectives must be considered. The first objective is
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
For the goal of evacuation, tow objectives must be considered. The second objective deals with
those who need protection or evacuation but cannot be moved for whatever reason. In case the objective is to shelter in place
43
Fire fighters responding to a ship fire will probably find the
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
Items included in the Fire control plan (FCP)
```
General layout of the ship
Dimensions
Locations of firefighting systems
Locations of the communication systems
Plans for each deck of the ship
```
45
Much information on the cargo and position of the railcars can be found
on the consist or the wheel report
46
Bulk storage facilities
| Preplanning should cover all the routine preplanning subjects and in addition
list the columns of products
the physical and chemical hazards
the technical assistance available
the level of evacuation that might be required
47
Low pressure tanks have different types of roofs
including cone roof
Floating roof
floating roof with geodesic dome
cover floating roof
48
Pressurized tanks hold
gases that are liquefied or stored in bulk under pressure
49
Bulk tanks are
generally steel constructed and may be closely laid out to one another in a tank farm arrangement.
50
Crews should not be place in line
with the ends of tanks counting pressurized gases.
51
Water should be applied in large quantities to the
vapor space of pressurized containers and to the sides below the liquid line of large liquid or non pressurized tanks
52
The substation fire is usually a
Class b fire after the electricity has been shut down.
