Questions and Answers
  • 1. 

    The most common cause of injuries on a construction site is

    • A.

      Burns

    • B.

      Cuts

    • C.

      Heat Stress

    • D.

      Fall from Height

    Correct Answer
    D. Fall from Height
    Explanation
    Falls from height are the most common cause of injuries on a construction site. Construction workers often work at elevated levels, such as on scaffolding, ladders, or roofs, which increases the risk of falling. These falls can result in serious injuries or even fatalities. It is crucial for construction sites to have proper safety measures in place, such as guardrails, harnesses, and safety nets, to prevent such accidents. Regular training and adherence to safety protocols are also essential to minimize the risk of falls from height.

    Foam type extinguishers are used to put out fires that burn

    • A.

      Flammable liquids

    • B.

      Ordinary combustibles

    • C.

      Electrical equipments

    • D.

      Combustible metals

    Correct Answer
    A. Flammable liquids
    Explanation
    Foam type extinguishers are used to put out fires that burn flammable liquids. These types of fires involve substances such as gasoline, oil, solvents, and other flammable liquids. Foam extinguishers work by smothering the fire and cooling the fuel source, preventing the fire from spreading and reigniting. The foam forms a barrier between the fire and the oxygen, effectively extinguishing the flames. This type of extinguisher is not suitable for fires involving ordinary combustibles, electrical equipment, or combustible metals.

    What should be the minimum width of a Working Platform?

    • A.

      250mm

    • B.

      300mm

    • C.

      600mm

    • D.

      900mm

    Correct Answer
    B. 300mm
    Explanation
    The minimum width of a working platform should be 300mm. This width ensures that there is enough space for a person to stand and move comfortably while working. It also provides stability and prevents the risk of falling or tripping. A narrower platform could be too cramped and unsafe, while a wider platform may not be necessary for most tasks. Therefore, 300mm is the appropriate minimum width for a working platform.

  • 8. 

    Which one shall be the "Last Step" of the Hierarchy of Control to minimize risk?

    • A.

      Elemination

    • B.

      Personal Protective Equipment

    • C.

      Substitution

    • D.

      Administration

    Correct Answer
    B. Personal Protective Equipment
    Explanation
    Personal Protective Equipment (PPE) should be the "Last Step" in the Hierarchy of Control to minimize risk. This means that before resorting to PPE, other control measures such as elimination, substitution, and administration should be considered and implemented first. PPE is considered the last resort because it only provides a barrier between the worker and the hazard, rather than eliminating or reducing the hazard itself. PPE should be used when all other control measures have been exhausted or are not feasible.

      Precautions for safe handling

    • D.

      Flash point of the chemical material

    Correct Answer
    A. Quantity of the chemical material
    Explanation
    The quantity of the chemical material is not included in an MSDS (Material Safety Data Sheet). An MSDS provides information about the health hazards of the chemical, precautions for safe handling, and the flash point of the chemical material. However, it does not disclose the specific quantity of the chemical material.

    Which safety gadget is used for vertical climbing during height work?

    • A.

      Safety Net

    • B.

      Full Body Harness

    • C.

      Life Line

    • D.

      Fall Arrestor

    Correct Answer
    D. Fall Arrestor
    Explanation
    A fall arrestor is a safety gadget used for vertical climbing during height work. It is designed to prevent a person from falling while working at heights. It typically consists of a harness that is worn by the worker and a retractable lanyard or lifeline that is attached to an anchor point. In the event of a fall, the fall arrestor activates and stops the person from falling further, minimizing the risk of injury. This safety device is essential for workers who need to climb or work at heights to ensure their safety and prevent accidents.

    What is a safe rating of ELCB used in Plant?

    • A.

      15 mA

    • B.

      20mA

    • C.

      25 mA

    • D.

      30 mA

    Correct Answer
    D. 30 mA
    Explanation
    The safe rating of an ELCB used in a plant is 30 mA. ELCB stands for Earth Leakage Circuit Breaker, which is a safety device used to detect and protect against electrical leakage currents. A leakage current of 30 mA is considered safe because it is below the threshold that can cause harm to humans. This rating ensures that the ELCB can effectively detect and interrupt the circuit in case of any leakage current above this level, preventing electrical shocks and potential hazards.

    What is the smothering process of extinguishing fire?

    • A.

      To remove fuel

    • B.

      To remove heat

    • C.

      To remove oxygen

    • D.

      To remove all of the above

    Correct Answer
    C. To remove oxygen
    Explanation
    The smothering process of extinguishing fire involves removing oxygen. Fire requires oxygen to sustain itself, so by removing oxygen, the fire is deprived of its essential element and is therefore extinguished. This can be done by covering the fire with a fire blanket, using a fire extinguisher that displaces oxygen, or by cutting off the oxygen supply to the fire.

      85dB

    • D.

      90dB

    Correct Answer
    D. 90dB
    Explanation
    The threshold limit of hearing refers to the minimum sound level that can be detected by the human ear. It is the point at which sound becomes audible to a person. The correct answer, 90dB, indicates that at this level or above, a sound can be heard by the average human ear.

    Height work permit is required for work at an elevation of 

    • A.

      1.5 Mtr

    • B.

      1.8 Mtr

    • C.

      2.0 Mtr

    • D.

      2.2 Mtr

    Correct Answer
    B. 1.8 Mtr
    Explanation
    A height work permit is required for work at an elevation of 1.8 meters. This means that any work that involves working at a height of 1.8 meters or above requires a permit. This is likely because working at such heights can pose significant risks and hazards, such as the potential for falls and injuries. Having a permit ensures that proper safety measures are in place and that workers are trained and aware of the risks associated with working at elevated heights.

    Explanation
    Unsafe Act refers to any action or behavior that deviates from the established safety protocols or procedures, leading to an accident. It suggests that human error or negligence is the primary cause of accidents, rather than external factors such as unsafe conditions or acts of nature. This answer implies that accidents are often preventable if individuals adhere to proper safety practices and take responsibility for their actions.

    Ladder can be safely used if it is placed at

    • A.

      45 degree

    • B.

      60 degree

    • C.

      75 degree

    • D.

      85 degree

    Correct Answer
    C. 75 degree
    Explanation
    A ladder can be safely used if it is placed at a 75-degree angle. This angle provides a good balance between stability and reach. Placing the ladder at a 45-degree angle may make it too steep and unstable, while placing it at a 60-degree angle may not provide enough reach. Placing it at an 85-degree angle may make it too shallow and prone to tipping over. Therefore, the safest option is to place the ladder at a 75-degree angle.

    Use of Asbestos hand gloves were banned because

    • A.

      It is costly than other gloves

    • B.

      It causes asbestosis

    • C.

      It is not able resist high temperature

    • D.

      None of the above

    Correct Answer
    B. It causes asbestosis
    Explanation
    Asbestos hand gloves were banned because they cause asbestosis. Asbestosis is a serious lung disease that occurs when asbestos fibers are inhaled and cause scarring of the lung tissue. This scarring can lead to difficulty breathing, coughing, and other respiratory issues. Asbestos is a known carcinogen and has been linked to various other health problems, including lung cancer and mesothelioma. Therefore, due to the severe health risks associated with asbestos exposure, its use in hand gloves has been prohibited.
