    When storing chemicals, segregate:

    • Flammables and combustibles from oxidizers

    • Oxidizing agents from reducing agents

    • Pyrophoric compounds from flammables

    • All of the above

    Correct Answer
    A. All of the above
    Explanation
    When storing chemicals, it is important to segregate different types of chemicals to prevent any potential reactions or hazards. Flammables and combustibles should be kept separate from oxidizers, as they can react and cause fires. Oxidizing agents should be stored separately from reducing agents to prevent any unwanted reactions. Pyrophoric compounds, which are substances that can ignite spontaneously, should also be stored separately from flammables to avoid any accidental fires. Therefore, all of the above options should be followed when storing chemicals to ensure safety.

    In order to be effective, the right PPE for the job must be used, and:

    • It must be worn correctly

    • It must be brand new

    • It must belong to the lab it is used in

    • It must be color coordinated

    Correct Answer
    A. It must be worn correctly
    Explanation
    The effectiveness of Personal Protective Equipment (PPE) relies on its correct usage. Even if the PPE is the right one for the job, it will not provide adequate protection if it is not worn correctly. This means that it should be worn in the proper manner, ensuring that all necessary parts are properly secured and covering the intended areas. Wearing PPE incorrectly can leave exposed areas vulnerable to hazards, rendering the equipment ineffective. Therefore, correct usage is crucial for the PPE to fulfill its purpose of protecting the wearer.

    A PEL is:

    • Particularly Explosive Liquid

    • Prohibitive Electric Level

    • Preventive Environmental Lobby

    • Permissible Exposure Limit

    Correct Answer
    A. Permissible Exposure Limit
    Explanation
    A PEL, or Permissible Exposure Limit, refers to the maximum allowable concentration of a hazardous substance in the air that a worker can be exposed to over a specific time period. This limit is set by regulatory agencies to protect workers from potential health risks associated with prolonged exposure to certain substances. The PEL ensures that workers are not exposed to levels of hazardous substances that could cause harm to their health.

     Which of the following is NOT a possible physical hazard characteristic of a chemical?

    • Reactive

    • Corrosive

    • Flammable

    • Acute

    Correct Answer
    A. Acute
    Explanation
    Acute is not a physical hazard characteristic of a chemical. Acute refers to the severity or intensity of an effect, such as acute toxicity, but it does not describe a physical hazard. Physical hazards of chemicals include reactivity, corrosiveness, and flammability, which are based on the chemical's properties and how it interacts with its environment.

    Chronic effects of chemical exposure are:

    • Effects that occur immediately after an exposure

    • Effects that occur after long term, multiple exposures

    • Treatable with first aid

    • A and C

    Correct Answer
    A. Effects that occur after long term, multiple exposures
    Explanation
    The correct answer is "Effects that occur after long term, multiple exposures." Chronic effects of chemical exposure refer to the health effects that develop over time and are a result of repeated or prolonged exposure to a chemical substance. These effects may not be immediately apparent and can manifest after a significant period of exposure. They are typically not treatable with simple first aid measures and may require medical intervention or long-term management.

    Which of the following is NOT a possible health hazard characteristic of a chemical?

    • Irritant

    • Corrosive

    • Allergen

    • All are possible health hazard characteristics

    Correct Answer
    A. All are possible health hazard characteristics
    Explanation
    All of the listed options - irritant, corrosive, and allergen - are possible health hazard characteristics of a chemical. An irritant can cause inflammation or discomfort to the skin, eyes, or respiratory system. A corrosive substance can cause severe damage or destruction to living tissue upon contact. An allergen can trigger an allergic reaction in individuals who are sensitive or allergic to it. Therefore, all the options mentioned pose potential health risks.

    Which of the following is NOT a possible route of entry for a chemical exposure?

    • Inhalation

    • Indigestion

    • Absorption

    • Injection

    Correct Answer
    A. Indigestion
    Explanation
    Indigestion is not a possible route of entry for a chemical exposure because it refers to the discomfort or pain in the upper abdomen that occurs after eating. Chemicals are not typically ingested through the digestive system unless intentionally consumed, unlike inhalation (breathing in chemicals), absorption (through the skin), and injection (directly into the bloodstream).

    Which of the following is NOT a Particularly Hazardous Substance according to OSHA?

    • Select carcinogens.

    • Reproductive toxins.

    • Corrosives.

    • Substances with a high degree of acute toxicity.

    Correct Answer
    A. Corrosives.
    Explanation
    According to OSHA, corrosives are not considered a Particularly Hazardous Substance. Particularly Hazardous Substances are substances that have been identified as being extremely hazardous to employees and require special handling. Carcinogens, reproductive toxins, and substances with a high degree of acute toxicity are all considered Particularly Hazardous Substances because they pose significant risks to health and safety. Corrosives, on the other hand, are substances that can cause damage to materials or living tissues through chemical reactions, but they are not classified as Particularly Hazardous Substances by OSHA.

    Name two chemical hygiene errors made by former President Bush in the photo shown of him in this presentation:

    Correct Answer
    Sniffing from the bottle
    Not wearing glove
    Bottle not labeled
    Explanation
    Former President Bush made two chemical hygiene errors in the photo shown. Firstly, he was sniffing directly from the bottle, which is a violation of proper chemical handling practices as it can lead to inhalation of harmful substances. Secondly, he was not wearing gloves while handling the bottle, which is essential to protect the skin from potential chemical exposure. Additionally, the bottle was not labeled, which is crucial for proper identification and safe handling of chemicals.
