Pg 476

Question 2

Spill control tactics reduce the amount of contact he product makes with:

Answer 2

Pg 476

Question 3

Leak control tactics are used to:

Answer 3

Contain the product in its original container or another container there by preventing it from escaping.
Pg 477

Question 4

Most leak control tactics are:

Answer 4

Offensive and performed by haz mat techs or specialists

Pg 477

Question 5

The main priority of spill control is called:

Answer 5

Confinement

Pg 477

Question 6

Spill control is primarily a defensive operation with the most important issue being:

Answer 6

The safety of the responders performing these actions

Pg 477

Question 7

The type of dispersion determines the:

Answer 7

Defensive measure needed to control it

Pg 478

Question 8

Before using equipment to confine spilled materials ICs need to:

Answer 8

Seek advice from technical sources to determine if the spilled materials will adversely affect the equipment
Pg 478

Question 9

Defensive spill control tactics that confine hazardous materials include the following:

Answer 9

Absorption
Adsorption
Blanketing/covering
Dam, dike, diversion, and retention
Vapor suppression
Pg 478

Question 10

Tactics to dilute the concentration or change the physical or chemical properties include:

Answer 10

Vapor dispersion
Ventilation
Dispersion
Dilution
Dissolution
Neutralization
Pg 478

Question 11

Absorption:

Answer 11

Combining two materials that have an attraction for each other and allowing on to retain the other
Pg 480

Question 12

Asorbent materails include:

Answer 12

Sawdust
Clays
Charcoal
Polyolefin type fibers
Pg 480

Question 13

Absorbent is spread:

Answer 13

Directly onto the haz mat or in a location it is expected to flow
Pg 480

Question 14

After use absorbents must be treated and disposed of as:

Answer 14

Hazardous materials

Pg 480

Question 15

Adsorption is different than absorption in that:

Answer 15

The molecules of the hazardous material physically adhere to the adsorbent material rather than being asorbed into the inner spaces of absorbent material
Pg 480

Question 16

Adsorbents are primarily used to control:

Answer 16

Shallow liquid spills.

Pg 480

Question 17

It is important to make sure that adsorbent used is compatbile with the spilled material to avoid:

Answer 17

Potentially dangerous reactions

Pg 480

Question 18

Blanketing or covering of solids can be done with:

Answer 18

Tarps
Plastic sheeting
Salvage covers 
Foam
Or other materials
Pg 480

Question 19

Blanketing of liquids is essentially the same as vapor suppression because;

Answer 19

It primarily uses an appropriate aqueous beam agent to cover the surface of the spill
Pg 481

Question 20

To control the flow of liquid hazardous materials away from the point of discharge you can:

Answer 20

Dam, dike, or divert

Pg 481

Question 21

Foams intended for polar solvents may be used on:

Answer 21

Hydrocarbon fires

Pg 483

Question 22

Foam drainage time:

Answer 22

The time required for 25% of the total liquid solution to drain from the foam
Pg 485

Question 23

Vapor dispersion is the action taken to:

Answer 23

Direct or influence the course of airborne hazardous materials
Pg 487

Question 24

Ventilation involves controlling the movement of air by:

Answer 24

Natural or mechanical means

Pg 487

Question 25

Dissolution:

Answer 25

The process of dissolving a gas in water

Pg 488

Question 26

Non pressure liquid tanks mc 306, low pressure chemical tanks mc307, and high pressure 331 will have an emergency shut off located:

Answer 26

On the left front corder of the tank behind the driver. Some will have on on either the right or left rear corner
Pg 490

Question 27

Fire control is the stateghy of:

Answer 27

Minimizing the damage, harm, and effect of fire at a hazmat incident
Pg 492

Question 28

When containers or tanks of flammable liquids or gases are exposed to flame impingement water streams should be deployed for:

Answer 28

Maximum effective reach in order to prevent a BLEVE

Pg 492

Question 29

Gas fed fires burning around relief valves of piping should no be extinguished unless:

Answer 29

Turning off the supply can stop he leaking product

Pg 492

Question 30

Cooling a water tank is best achieved by:

Answer 30

Directing streams at areas where there is direct flame impingement on the tank as well as along the tanks top so water runs down both sides
Pg 492

Question 31

When water streams are used to disperse gas being released under pressure:

Answer 31

The mass and velocity of the water must exceed the mass and velocity of the escaping gas
