The local role in reducing public risks from hazardous materials includes: - CORRECT ANSWER 1) Developing an emergency plan for hazardous materials incidents 2) Regulating hazardous materials transportation through local ordinances 3) Regulating safe disposal of hazardous waste LEPC - CORRECT ANSWER If you believe a local manufacturer is not in compliance with Title III, you should: department of transportation - CORRECT ANSWER The Federal agency responsible for regulating hazardous materials transportation is: NFPA 704 Labeling System - CORRECT ANSWER Indicates health, flammability, and reactivity hazards of Chemicals (through scale of 0-4)v There are three possible codes for the bottom quarter of the NFPA symbol, what does OXY mean? - CORRECT ANSWER This means this material is an oxidizer. It can easily release oxygen to create or worsen a fire or explosion hazard. There are three possible codes for the bottom quarter of the NFPA symbol, what does the symbol W mean? - CORRECT ANSWER This indicates a material that reacts with water to release a gas that is either flammable or hazardous to health There are three possible codes for the bottom quarter of the NFPA symbol, what does the tri-blade propeller mean? - CORRECT ANSWER The material is radioactive Explosives in Class 1 are divided into six divisions, what is 1.1? - CORRECT ANSWER consists of explosives that have a mass explosion hazard. A mass explosion is one that affects almost the entire load instantaneously. explosives in class 1 are divided into six divisions, what is 1.2? - CORRECT ANSWER consists of explosives that have a projection hazard but not a mass explosion hazard. Explosives in Class 1 are divided into six divisions, what is 1.3? - CORRECT ANSWER consists of explosives that have a fire hazard and either a minor blast hazard or a minor projection hazard or both, but not a mass explosion hazard. Explosives in Class 1 are divided into six divisions, what is 1.4? - CORRECT ANSWER consists of explosives that present a minor explosion hazard. What is the Emergency Response Guidebook primarily used for/by? - CORRECT ANSWER primarily a guide to aid "first responders" in quickly identifying the specific or generic hazards of the material(s) involved in the incident, - along with protecting themselves and the general public during the initial response phase of the incident. What are the dangers of TIC? - CORRECT ANSWER They have low TLVs and PELs which means they are very toxic if "first responders" are exposed to their liquid or vapor hazards. The best source for information on where hazardous materials are stored or released from fixed sites in your community is usually: - CORRECT ANSWER The LEPC On which of the following might you find an NFPA 704 label? - CORRECT ANSWER A storage tank You find on an NFPA label that the left side of the quadrant, which is blue, has a rating of 4. This means that: - CORRECT ANSWER A very short exposure to the substance could cause serious injury or death The symbol W on an NFPA label means that: - CORRECT ANSWER You should not add water to the substance DOT requires highway cargo tanks and railroad tank cars with regulated hazardous contents to bear a four-digit number identifying the load if they are: - CORRECT ANSWER Moving in interstate commerce The CWA that interferes with the body's ability to transfer oxygen to the cells is: - CORRECT ANSWER AC Results of Commodity Flow Surveys which outline the types of hazardous materials being shipped through your community can be obtained from: - CORRECT ANSWER LEPC The SDS provides - CORRECT ANSWER important information on a substance's composition, potential hazards, and specific first aid procedures required in the event of an emergency. What is the containment approach to cleaning contaminated soil: - CORRECT ANSWER The objective of this approach is to leave the waste in place and try to keep it from moving into the soil, air, or groundwater. - Unfortunately, natural forces have triumphed in many landfills to date, and systems expected to last decades have made it only a few years before leaking. What is the Off-Site Disposal approach to cleaning contaminated soil: - CORRECT ANSWER Under this approach, hazardous materials are removed to a RCRA site. - Often, risks are transferred rather than eliminated; a number of RCRA landfills have begun to leak and have been added to the NPL for cleanup What is the Treatment approach to cleaning contaminated soil: - CORRECT ANSWER Numerous technologies are available or are currently being explored to chemically treat waste so that it is no longer harmful. - The best method varies according to the waste. Some waste can be biodegraded by adding microorganisms specifically bred to "eat up" the chemicals; organic chemicals can sometimes be forced to break down when high temperatures are applied. Three water treatment approaches are currently in use, explain Air Stripping/Aeration - CORRECT ANSWER Water is brought to the surface and agitated or sprayed into the air to accelerate the evaporation of organic compounds. - Citizens near a site using this method need to ask questions about the rate at which toxic elements are released into the atmosphere, particularly if residential areas are located near the stripping tower. Three water treatment approaches are currently in use, explain Activated Carbon - CORRECT ANSWER This treatment passes water through columns containing activated carbon, leaving many chemicals attached to the carbon particles. - A sensitive issue in this type of treatment is how to dispose of the contaminated carbon. Three water treatment approaches are currently in use, explain Chemical Precipitation - CORRECT ANSWER In this approach, primarily used to remove metals such as lead and arsenic, chemicals are added which can convert metals to insoluble particles. These particles then settle out of the water as sludge. - The controversial issue with this method is the disposal of the toxic sludge. The __________ usually prepares the SDS of a hazardous substance: - CORRECT ANSWER The manufacturer or distributor To inform workers of hazards a chemical may pose, OSHA requires employers to develop a: - CORRECT ANSWER Hazard Communication Program Health hazards of a given chemical would be found in what section of the SDS? - CORRECT ANSWER Section VI Personal protective clothing and equipment for safe handling of the chemical would be discussed in what section of the SDS? - CORRECT ANSWER Section VIII Permissible exposure limits are levels of exposures mandated by: - CORRECT ANSWER OSHA OSHA's PEL for hydrogen fluoride (HF) is? - CORRECT ANSWER 3.0 ppm In a major incident, a local government may have to call on State agencies for specialized resources and knowledge -- The Department of Fish and Game and Regional Water Quality Control Boards - CORRECT ANSWER provide recommendations and guidelines when hazardous material spills are likely to contaminate streams and/or waterways, or would otherwise affect wildlife resources. In a major incident, a local government may have to call on State agencies for specialized resources and knowledge -- State OSHA personnel - CORRECT ANSWER often possess a large reservoir of technical knowledge useful to an Incident Commander in the areas of exposure to, protection from, and control of hazardous materials. In an incident in which employees have been injured due to exposure, or in a prolonged incident, State OSHA personnel may respond. In a major incident, a local government may have to call on State agencies for specialized resources and knowledge -- The State Department of Health - CORRECT ANSWER employs health scientists who can help assess the potential human impact of a toxic release. In a major incident, a local government may have to call on State agencies for specialized resources and knowledge -- The State Department of Environmental Protection - CORRECT ANSWER can predict the environmental impact of actions the Incident Commander is considering. In a major incident, a local government may have to call on State agencies for specialized resources and knowledge -- The State and local Fire Marshals - CORRECT ANSWER have specific expertise relating to chemical behavior and State fire codes. Hazardous Materials Response Teams (HMRTs) - CORRECT ANSWER An HMRT is a specialized emergency response team formed to provide the particular skills, knowledge, and technical equipment needed to handle hazardous materials incidents. The chemical industry was the first provider of these services because it manufactured, transported, and used the products involved. Regional Response Teams (RRTs) - CORRECT ANSWER Regional Response Teams may be assembled to provide advice and support for transportation or fixed facility incidents that surpass the capability of State and local governments. The RRT reports to an On-Scene Coordinator who directs the response in keeping with the local Incident Commander. RRTs are composed of representatives from Federal agencies and a representative from each State within a Federal Region What is the minimum number of persons needed to manage a hazardous materials incident safely? - CORRECT ANSWER 8 The most critical element in avoiding confusion and conflict among responders at a hazardous materials incident is: - CORRECT ANSWER A good plan which all responders know and use The person in charge of managing responding forces at a hazardous materials incident is: - CORRECT ANSWER The Incident Commander (usually from the local fire service) Which of the following should you do if you are in your car and learn that there is an accident involving a volatile toxic substance ahead of you on the road? - CORRECT ANSWER Follow instructions and remain clear of the release plume Which of the following is not typically represented on a Local Emergency Planning Committee? - CORRECT ANSWER The Governor The success of any site operation and readiness of employees to respond to emergencies is based on: - CORRECT ANSWER Initial and annual refresher training
