HAZMAT Tech 2 - ALL

275 Questions covering all the material

QuestionAnswer
The action options and response objectives fall into these three types. Offensive, Defensive, Nonintervention
Action options and response objectives are based on: Estimated outcomes, Stage of the incident, Strategic goals
The following steps should be taken when determining response objectives. Estimate the exposures that could be saved. Determine the response objectives. Focus on changing the actions of the stressors, the containment system, and the hazardous material.
The response objectives are: Change the applied stress. Change the breach size. Change quantity released. Change size of the danger zone. Change exposures contacted. Change severity of harm.
ways to “Change Applied Stress” are: Move stressor. Move stressed system. Shield stressed system.
ways to “Change Breach Size” are: Chill contents. Limit stress levels. Activate venting devices. Mechanical repair.
Four ways to “Change Quantity Released” are: Change container position. Minimize pressure differential. Cap off breach. Remove contents.
ways to “Change Size of the Danger Zone” are: Barriers. Adsorbents. Absorbents. Diluents. Reactants. Overpack.
ways to “Change Exposures Contacted” are: Provide sheltering. Begin Evacuation. PPE.
ways to “Change Severity of Harm” are: Rinse off contamination. Increase distance from source. Provide shielding. Provide prompt medical attention.
Principals that apply to response objectives are One cannot influence events that already happened. The earilier the event sequence can be interupted the more acceptable the loss (the better?)
