  • 2. 

    Which recommendation should be followed first when a fire in the workplace is out of control?

    • Try to use the elevators or lifts to get out of the building

    • Try to get out of the room and contact the emgergency services

    • Open all windows and jump for it

    • Run around screaming until someone punches you in the face

    Correct Answer
    A. Try to get out of the room and contact the emgergency services
    Explanation
    When a fire in the workplace is out of control, the first recommendation that should be followed is to try to get out of the room and contact the emergency services. This is the most logical and practical course of action to ensure personal safety and to alert the appropriate authorities for immediate assistance. Trying to use elevators or lifts may be dangerous as they could malfunction or become inaccessible during a fire. Opening windows and jumping is also extremely risky and should be avoided. Running around screaming is not a helpful or productive response in such a situation.

    What does ESD stand for?

    • Electrostatic detectives

    • Electrostatic dymanics

    • Electrostatic dummies

    • Electrostatic discharge

    Correct Answer
    A. Electrostatic discharge
    Explanation
    ESD stands for Electrostatic Discharge. Electrostatic discharge refers to the sudden flow of electricity between two objects with different electrical potentials. It occurs when there is a buildup of static electricity on one object and it discharges to another object. ESD can cause damage to electronic components and devices, which is why measures such as grounding and ESD protection are important in handling sensitive electronics.

    Rate this question:

  • 4. 

    Which of these conditions refers to a dramatic increase in voltage, which is usally caused by lightening?

    • Pulse

    • Sag

    • Call the techies my PC is fried!

    • Spike

    Correct Answer
    A. Spike
    Explanation
    A spike refers to a dramatic increase in voltage, usually caused by lightning. This sudden surge in voltage can potentially damage electrical equipment, including computers. It is important to protect electronic devices from spikes by using surge protectors or unplugging them during storms to prevent damage.

    Rate this question:

  • 5. 

    Which of these is a fact sheet that summarises information about material identicication?

    • MSFS

    • MIFS

    • MILFS

    • MSDS

    Correct Answer
    A. MSDS
    Explanation
    MSDS stands for Material Safety Data Sheet, which is a fact sheet that provides essential information about a particular material or substance. It summarizes important details such as the material's identification, hazards, handling and storage instructions, emergency procedures, and more. MSDSs are commonly used in workplaces to ensure the safe handling and use of materials, and they are an important resource for employees to understand the potential risks associated with a substance and how to mitigate them.

  • 6. 

    Which types of clothing are likely to generate a static charge?

    • Wool

    • Cotton

    • Silk

    • All of the above

    Correct Answer
    A. All of the above
    Explanation
    Wool, cotton, and silk are all likely to generate a static charge. These materials have the ability to rub against other surfaces and create friction, which leads to the buildup of static electricity. When two materials with different electrical properties come into contact and then separate, electrons can be transferred, resulting in a static charge. Therefore, all three types of clothing mentioned can generate a static charge.

    Rate this question:

  • 7. 

    What is the minimum level of electrostatic discharge that a person can normally feel?

    • 30 volts

    • 300 volts

    • 3000 volts

    • 30,000 volts

    Correct Answer
    A. 3000 volts
    Explanation
    The minimum level of electrostatic discharge that a person can normally feel is 3000 volts.

    Rate this question:

  • 8. 

    What class of fire extinguisher is used on an electrical fire?

    • Class A

    • Class B

    • Class C

    • Class D

    Correct Answer
    A. Class C
    Explanation
    Class C fire extinguishers are specifically designed to extinguish fires involving electrical equipment. These extinguishers contain non-conductive agents, such as carbon dioxide or dry chemical, that do not conduct electricity. This is crucial in preventing electrical shock to the person using the extinguisher. Class C extinguishers are labeled with a blue circle and the letter "C" to indicate their suitability for electrical fires.

    Which command is used to prepare a hard drive to store information?

    • Defrag

    • Format

    • Boot Disk

    • Boot Computer

    Correct Answer
    A. Format
    Explanation
    The command "Format" is used to prepare a hard drive to store information. This command erases all the data on the hard drive and sets up the file system, making it ready to store new information. It creates a new file allocation table and directory structure, allowing the operating system to organize and access the data efficiently.

  • 10. 

    Which screwdriver should be used to remove screws that have a star-like depression on top?

    • Torox

    • Flat head

    • Hex driver

    • Bus driver

    Correct Answer
    A. Torox
    Explanation
    A Torox screwdriver should be used to remove screws that have a star-like depression on top. This type of screwdriver has a tip that matches the star-like shape of the screw, allowing for a secure and precise fit. Using any other type of screwdriver, such as a flat head or hex driver, may result in damage to the screw or the tool itself. A "Bus driver" is not a type of screwdriver and is not relevant to this question.
