Flashcards in Ch. 7: Hazard Assessment and Risk Evaluation Deck (55)
What is the most critical decision-making point in the successful management of a hazardous materials incident?
The evaluation of hazard information and the assessment of risks.
What is recognized as a critical benchmark in safe and successful emergency response operations?
The concept of hazard assessment and risk evaluation.
What refer to a danger or peril?
What refer to the probability of suffering harm or loss?
What are the three distinct, but inter-related tasks of the hazard and risk evaluation process?
1) Hazard Assessment
2) Risk Evaluation
3) Development of the IAP
What must responders understand to mount a safe and effective hazmat response?
1) how the enemy will behave
2) how it can harm
3) how these properties are influenced by the environment where the incident is occuring
What provide information on the behavior of a material?
What is known as the pressure exerted by the vapor within the container against the sides of the container?
The weight of a solid or liquid material as compared with the weight of an equal volume of water.
The weight of a pure vapor or gas compared with the weight of an equal volume of dry air at the same temperature and pressure.
The temperature at which a liquid changes its phase to a vapor or gas.
The temperature at which a solid changes its phase to a liquid.
The ability of a substance to change from the solid to the vapor phase without passing through the liquid phase.
The temperature above which a gas cannot be liquefied no matter how much pressure is applied.
The pressure that must be applied to liquefy a gas at its critical temperature.
The rapid release of a liquefied gas that causes it to rapidly cool, slow down the boiling process, and remain in a liquid state.
The ease with which a liquid or solid can pass into the vapor state.
The rate at which a material will vaporize or change from liquid to vapor.
The amount of gas produced by the evaporation of one volume of liquid at a given temperature.
The ability of a solid, liquid, gas or vapor to dissolve in water or other specified medium.
The ability of materials to dissolve into a uniform mixture.
Measurement of the thickness of a liquid and its ability to flow.
What are the intrinsic characteristics or properties of a substance described by its tendency to undergo chemical change?
What typically provides responders with an understanding of how a material may harm?
Concentration of material to which the body is exposed over a specific time period.
Minimum temperature at which a liquid gives off sufficient vapors that will ignite and flash over, but will not continue to burn without the addition of more heat.
Minimum temperature at which a liquid gives off sufficient vapors that will ignite and sustain combustion.
The minimum temperature required to ignite gas or vapor without a spark or flame being present.
The range of gas or vapor concentration that will burn or explode if an ignition source is present.
