27

30
Q

TFD personnel shall respond to hazardous materials incidents according to the
following seven step process

A
  1. Management
  2. Identification of the hazardous material(s)
  3. Evaluation of hazards
  4. Selection of PPE
  5. Containment and control
  6. Decontamination
  7. Termination
31
Q

The Incident Commander shall

A

a. Determine if a hazardous material is involved.
b. Record hazardous materials data on the field copy of the Hazardous Materials Worksheet (FIR 411).
c. Relay information to Fire Communications on a regular basis

32
Q

When selecting a stand-by area for other responding units, the Incident
Commander shall announce on the tactical channel the location of a site that is?

A

a. Well away from the hazard.
b. Within 3 minutes from the scene.
c. Up-wind and uphill from the scene.

33
Q

When an entry team is in the Hot Zone, a backup rapid intervention
crew (RIC) shall be standing by in the?

A

Cold Zone wearing the appropriate level of protective clothing.

34
Q

The Incident Commander shall order building evacuation under the
following circumstances

A

a. Leaks involving unknown gases from large-capacity storage containers.
b. Explosives or large quantities of materials which could detonate or explode causing damage to structures in the immediate area.
c. Leaks or releases that cannot be controlled and are expected to continue leaking/releasing such that it places civilian lives at risk.

35
Q

For large-scale evacuations, the Incident Commander shall contact Fire
Communications to request?

A

that the Emergency Coordination Center (ECC) be activated.

a. The Incident Commander shall have direct and frequent communication with the ECC liaison.
b. During extended operations, the EOC liaison shall remain in the Command Post and have direct communications with the ECC.

36
Q

All TFD personnel responding to a hazardous materials incident should be
able to identify and understand the hazards presented by vapors

A

a. Vapor pressure is directly affected by temperature and pressure.
i. The higher the temperature, the faster a material will evaporate.
ii. The lower the pressure, the faster a material will evaporate.
b. Vapors with a value greater than 1 tend to move and collect in low places.
c. Vapors with a value of less than 1 tend to float up and dissipate.

37
Q

All TFD personnel shall be able to recognize the hazards presented by
flammable and explosive materials:

A

a. The lower the flash point, the higher the fire hazard.
b. A flammable gas requires a minimum concentration in air in order to “flash.”
i. Any concentration below this is considered too “lean” to support combustion.
c. The higher the LEL, the more difficult it is to produce a concentration that will ignite (e.g., ammonia with a LEL of 15%).
d. A very low LEL indicates a very high explosion hazard (e.g.,
methyl ethyl ketone (MEK) with a LEL of 1.4%).
e. The UEL indicates the percentage of gas in air mixture at which a gas becomes too “rich” to support combustion or there is too much gas.
f. The UEL indicates the upper limit of the flammable range of a gas.
i. The larger the gap between the LEL and the UEL, the higher the hazard of explosion.
ii. When a fuel/air mixture is above its UEL, the mixture will fall into a range that can ignite the farther out it is from the source.

38
Q

TFD personnel shall consider the following toxicity threshold limits when determining health hazard

A

a. Immediately dangerous to life or health (IDLH)
b. Short-term exposure limit (STEL)
c. Time-weighted average (TWA)/Recommended exposure limits (REL)/Permissible exposure limits (PEL).

39
Q

TFD chemical protective clothing shall not be worn as primary protection
in atmospheres determined by any TFD air monitoring equipment to be

A

above 10% of the lower explosive limit.

or booby traps in the lab.
b. Retrace their steps to the outside.
