HAZMAT Technician Exam Questions and Answers 100% Pass

HAZMAT Technician Exam Questions and Answers 100% Pass Acid - - pH less than 7 - Reacts with bases and certain metals to form salts - Turns blue litmus red Caustic (Base) - - pH greater than 7 - Reacts with acids and certain metals to form salts Air Reactivity - Materials that can react or ignite if they are exposed to air. Auto-refrigeration - A phenomenon that occurs during the rapid release (boiling) of a liquefied gas that causes it to temporarily remain in a liquid state through rapid cooling. RISK: False assumption of product elimination until the product resumes boiling and subsequent release. Biological Agents - Biological Agents include bacteria, viruses, fungi, other microorganisms and their associated toxins. Many microbes reproduce rapidly and require minimal resources for survival; therefore, they are a potential danger in a wide variety of occupational settings.

RISK: Affects human health in a variety of ways ranging from allergic reactions to death. Blood Agent - A chemical compound, including the cyanide group, which affects bodily functions by preventing the normal utilization of oxygen by body tissues. The term "blood agent" is a misnomer, however, because these agents do not actually affect the blood in any way. Boiling Point - Temperature at which the transition from a liquid to a gas state occurs. At this temperature, the vapor pressure of a liquid equals the surrounding atmospheric pressure so that the liquid rapidly becomes a vapor. Catalyst - a substance that accelerates the rate of a chemical reaction without itself changing. Chemical Change - Changes that take place on the molecular level. A chemical change produces a new substance. Chemical Interactions - Caused when two or more chemicals, or the chemical and its container are incompatible. Compound Mixture - Separate elements that bond together to form compound mixture, they have a tendency to break down into their component parts, sometimes in an explosive manner. Concentration - When dealing with corrosives, the amount of acid or base is compared to the amount of water present. Critical Temperature - the temperature above which gas cannot be liquefied no matter what pressure is applied. critical pressure - The pressure that must be applied to bring a gas to its liquid state.

All rights reserved © 2025 Dissociation - The separation of a substance into two or more simpler substances, or of a molecule into atoms or ions by the action of heat or a chemical process. Usually reversible. Corrosive - A measure of a substance's tendency to deteriorate in the presence of another substance or in a particular environment. Dose - The concentration or amount of material to which the body is exposed over a specific time period Dose Response - The biological reaction caused by the dose in the body. The degree of harm is directly related to the dose (time and amount) and it's impact on bodily functions. Expansion ratio - The amount of gas produced by a given volume of liquid at a given temperature. Flash Point - The minimum temperature at which a material gives off vapor in sufficient concentration to form an ignitable mixture with air and will not continue to burn. Fire Point - The temperature at which enough vapors are given off to support continuous burning. Flammable - the difference between the upper and lower
