Chapter 10 Product Control Flashcards
Spill control actions are generally _______ in nature:
Defensive
Pg 476
Spill control tactics reduce the amount of contact he product makes with:
People property and the environment. There by limiting the amount of potential harm
Pg 476
Leak control tactics are used to:
Contain the product in its original container or another container there by preventing it from escaping.
Pg 477
Most leak control tactics are:
Offensive and performed by haz mat techs or specialists
Pg 477
The main priority of spill control is called:
Confinement
Pg 477
Spill control is primarily a defensive operation with the most important issue being:
The safety of the responders performing these actions
Pg 477
The type of dispersion determines the:
Defensive measure needed to control it
Pg 478
Before using equipment to confine spilled materials ICs need to:
Seek advice from technical sources to determine if the spilled materials will adversely affect the equipment
Pg 478
Defensive spill control tactics that confine hazardous materials include the following:
Absorption Adsorption Blanketing/covering Dam, dike, diversion, and retention Vapor suppression Pg 478
Tactics to dilute the concentration or change the physical or chemical properties include:
Vapor dispersion Ventilation Dispersion Dilution Dissolution Neutralization Pg 478
Absorption:
Combining two materials that have an attraction for each other and allowing on to retain the other
Pg 480
Asorbent materails include:
Sawdust Clays Charcoal Polyolefin type fibers Pg 480
Absorbent is spread:
Directly onto the haz mat or in a location it is expected to flow
Pg 480
After use absorbents must be treated and disposed of as:
Hazardous materials
Pg 480
Adsorption is different than absorption in that:
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
Adsorbents are primarily used to control:
Shallow liquid spills.
Pg 480
It is important to make sure that adsorbent used is compatbile with the spilled material to avoid:
Potentially dangerous reactions
Pg 480
Blanketing or covering of solids can be done with:
Tarps Plastic sheeting Salvage covers Foam Or other materials Pg 480
Blanketing of liquids is essentially the same as vapor suppression because;
It primarily uses an appropriate aqueous beam agent to cover the surface of the spill
Pg 481
To control the flow of liquid hazardous materials away from the point of discharge you can:
Dam, dike, or divert
Pg 481
Foams intended for polar solvents may be used on:
Hydrocarbon fires
Pg 483
Foam drainage time:
The time required for 25% of the total liquid solution to drain from the foam
Pg 485
Vapor dispersion is the action taken to:
Direct or influence the course of airborne hazardous materials
Pg 487
Ventilation involves controlling the movement of air by:
Natural or mechanical means
Pg 487
Dissolution:
The process of dissolving a gas in water
Pg 488
Non pressure liquid tanks mc 306, low pressure chemical tanks mc307, and high pressure 331 will have an emergency shut off located:
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
Fire control is the stateghy of:
Minimizing the damage, harm, and effect of fire at a hazmat incident
Pg 492
When containers or tanks of flammable liquids or gases are exposed to flame impingement water streams should be deployed for:
Maximum effective reach in order to prevent a BLEVE
Pg 492
Gas fed fires burning around relief valves of piping should no be extinguished unless:
Turning off the supply can stop he leaking product
Pg 492
Cooling a water tank is best achieved by:
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
When water streams are used to disperse gas being released under pressure:
The mass and velocity of the water must exceed the mass and velocity of the escaping gas
Pg 494
