    What are the chemical hazards increases at the time of concentration of the chemical

    • Flammability

    • Toxicity

    • Corrosivity

    • All of the above

    Correct Answer
    A. All of the above
    Explanation
    When the concentration of a chemical increases, the chemical hazards also increase. This is because higher concentrations can lead to increased flammability, toxicity, and corrosivity. Higher concentrations of a flammable chemical increase the likelihood of a fire or explosion. Similarly, higher concentrations of a toxic chemical can result in more severe health effects when exposed to it. Lastly, corrosivity refers to the ability of a chemical to cause damage or destruction to materials or living tissues, and higher concentrations can enhance this corrosive potential. Therefore, all of the mentioned chemical hazards can increase with an increase in the concentration of the chemical.

    What is CAS?

    • Chemical Abstracts Services

    • Common abstracts services

    • Chemical abstracts serial

    • Chemical American services

    Correct Answer
    A. Chemical Abstracts Services
    Explanation
    CAS stands for Chemical Abstracts Services. It is a division of the American Chemical Society and is responsible for the production and maintenance of the Chemical Abstracts database, which is a comprehensive collection of chemical literature and information. CAS provides access to a wide range of scientific research, including journal articles, patents, conference proceedings, and more. It is widely used by researchers, scientists, and professionals in the field of chemistry to find and retrieve information on various chemical substances and their properties.

    What route of exposure probably result into serious health hazard for TDI?

    • Inhalation

    • Ingestion

    • Passage through the skin

    • Skin exposure

    Correct Answer
    A. Inhalation
    Explanation
    Inhalation is the most likely route of exposure to result in a serious health hazard for TDI. TDI, or toluene diisocyanate, is a chemical compound commonly used in the production of polyurethane foams and coatings. Inhalation of TDI can lead to respiratory irritation, difficulty breathing, and in severe cases, asthma or other respiratory disorders. Ingestion and skin exposure to TDI can also pose health risks, but inhalation is considered the most hazardous route of exposure due to the direct contact of the chemical with the respiratory system.

    What do you mean by STEL?

    • Short term expanding level

    • Short time expanding limit

    • Short term exposure level

    • Short term exposure limit

    Correct Answer
    A. Short term exposure limit
    Explanation
    STEL stands for Short Term Exposure Limit. It refers to the maximum concentration of a hazardous substance that a worker can be exposed to over a short period of time (usually 15 minutes) without experiencing adverse health effects. This limit is set to protect workers from the immediate effects of exposure to hazardous substances.

    What chemical property can tell you whether a liquid is flammable at room temperature?

    • Lower Explosive Limit

    • Flashpoint

    • Upper Explosive Limit

    • Autoignition temperature

    Correct Answer
    A. Flashpoint
    Explanation
    The flashpoint of a liquid is the minimum temperature at which it gives off enough vapor to form an ignitable mixture with air. This means that if a liquid has a low flashpoint, it is more likely to be flammable at room temperature. Therefore, the flashpoint is the chemical property that can indicate whether a liquid is flammable at room temperature.

  • 7. 

    What property of a substance is most important in determining how quickly a chemical penetrates your skin, which is primarily made of liquids?

    • Water solubility

    • Oil solubility

    • Flashpoint

    • PH

    Correct Answer
    A. pH
    Explanation
    The property of a substance that is most important in determining how quickly a chemical penetrates the skin is pH. The pH level of a substance determines its acidity or alkalinity, which can affect the permeability of the skin. The skin has a slightly acidic pH, and substances with a similar pH are more likely to penetrate the skin quickly. Substances with a higher or lower pH can disrupt the skin's barrier function and increase the rate of penetration. Therefore, pH is a crucial factor in determining the speed at which a chemical can penetrate the skin.

    What is the primary goal of a flammable liquids storage cabinet

    • Make flammable liquids easy to find in case of fire

    • Contain flammable liquids in case of a spill

    • To protect the chemicals in the cabinet from a fire outside the cabinet

    • To contain a fire inside the cabinet

    Correct Answer
    A. To protect the chemicals in the cabinet from a fire outside the cabinet
    Explanation
    The primary goal of a flammable liquids storage cabinet is to protect the chemicals in the cabinet from a fire outside the cabinet. This means that the cabinet is designed to withstand and resist the heat and flames of a fire, preventing it from reaching and igniting the flammable liquids stored inside. The cabinet acts as a barrier, providing a safe and secure storage space for these hazardous materials, reducing the risk of fire and potential harm to individuals and property.

    UN class label 3 mean?

    • Explosive

    • Corrosive

    • Flammable

    • Oxidizer

    Correct Answer
    A. Flammable
    Explanation
    UN class label 3 refers to substances that are flammable. This means that they can easily catch fire and burn when exposed to a source of ignition. Flammable substances have a low flash point and can ignite at relatively low temperatures. They pose a fire hazard and can contribute to the spread of fires. It is important to handle and store flammable substances with caution to minimize the risk of accidents and fires.

    What is the primary goal of a flame arrestor on the storage tank?

    • Make flammable liquids easy to find in case of fire

    • Contain flammable liquids in case of a spill

    • To protect the chemicals in the tank from a fire outside the tank

    • All of above

    Correct Answer
    A. To protect the chemicals in the tank from a fire outside the tank
    Explanation
    A flame arrestor on a storage tank is designed to prevent the spread of fire from outside the tank to the chemicals stored inside. It acts as a barrier, allowing the flammable vapors to escape from the tank and dissipate, while preventing any external flame or ignition source from entering the tank and causing an explosion or fire. This helps to protect the chemicals stored in the tank and minimize the risk of a catastrophic event.
