    If you have to use a vibrating tool, what would you expect your supervisor to do?

    • Measure the level of the vibration while you use the tool

    • Tell you about the risks assessment and explain the safe way to use the tool

    • Watch you use the tool to assess the level of vibration

    • Help you to make up your own safe system of work

    Correct Answer
    A. Tell you about the risks assessment and explain the safe way to use the tool
    Explanation
    The supervisor should inform the worker about the risks assessment associated with using a vibrating tool and provide an explanation on how to safely use the tool. This ensures that the worker is aware of any potential dangers and understands the proper procedures to minimize the risks involved in using the tool. By providing this information, the supervisor is promoting a safe working environment and helping the worker to avoid any potential harm or accidents while using the vibrating tool.

    What is vibration white finger?

    • A mild skin rash that will go away

    • A serious skin condition that will not clear up

    • Severe frostbite

    • A sign of damage to your hands and arms that might not go away

    Correct Answer
    A. A sign of damage to your hands and arms that might not go away
    Explanation
    Vibration white finger refers to a condition where damage is caused to the hands and arms due to prolonged exposure to vibrating tools or machinery. It is not just a mild skin rash that will go away, but rather a more serious skin condition that may not clear up completely. The term "vibration white finger" is used to describe the appearance of the fingers turning white due to reduced blood flow. This condition can cause long-term damage and may not completely go away even with treatment.

    Noise over a long time can damage your hearing.  Can this damage be reversed?

    • Yes, with time

    • Yes, if you have an operation

    • No, the damage is permanent

    • Yes, if you change jobs

    Correct Answer
    A. No, the damage is permanent
    Explanation
    Exposure to noise over a prolonged period can lead to damage to the auditory system, specifically the delicate hair cells in the inner ear. These hair cells are responsible for transmitting sound signals to the brain. Once these cells are damaged, they do not regenerate or repair themselves. Therefore, the damage caused by noise exposure is generally irreversible and permanent.

    Why is vibration a serious health issue?

    • There are no early signs

    • The long-term effects of vibration are not known

    • There is no way that exposure to vibration can be prevented

    • Vibration can cause a disabling injury that cannot be cured

    Correct Answer
    A. Vibration can cause a disabling injury that cannot be cured
    Explanation
    Vibration can be a serious health issue because it has the potential to cause a disabling injury that cannot be cured. This means that once someone is injured due to excessive vibration exposure, there is no known treatment or remedy to fully recover from the injury. This highlights the severity of the health risks associated with vibration and the importance of taking preventive measures to minimize exposure.

    Which of these is most likely to cause vibration white finger?

    • Electric hoist

    • Hammer drill

    • Hammer and chisel

    • Battery-powered screwdriver

    Correct Answer
    A. Hammer drill
    Explanation
    A hammer drill is most likely to cause vibration white finger. This is because hammer drills generate high levels of vibration due to their rapid hammering action. Prolonged use of a hammer drill can lead to damage in the blood vessels, nerves, and muscles of the hand, causing vibration white finger. Electric hoists, battery-powered screwdrivers, and hammer and chisel may also cause some vibration, but they are less likely to cause the condition compared to a hammer drill.

    If you have to use a vibrating tool, how can you help reduce the effects of hand-arm vibration?

    • Hold the tool tightly

    • Do the work in short spells

    • Do the job in one long burst

    • Only use one hand on the tool at a time

    Correct Answer
    A. Do the work in short spells
    Explanation
    Doing the work in short spells helps reduce the effects of hand-arm vibration because it allows for regular breaks, which helps to minimize continuous exposure to the vibrating tool. Taking breaks allows the muscles and tissues in the hands and arms to rest and recover, reducing the risk of developing hand-arm vibration syndrome or other related injuries.

    Noise may be a problem in your work area if you have to shout to be clearly heard by someone who is standing?

    • 2 metres away

    • 4 metres away

    • 5 metres away

    • 6 metres away

    Correct Answer
    A. 2 metres away
    Explanation
    If you have to shout to be clearly heard by someone who is standing 2 meters away, it indicates that there is a high level of noise in your work area. This suggests that noise may be a problem in your work area.

    You are less likely to suffer from hand-arm vibration if you are:

    • Very cold but dry

    • Cold and wet

    • Warm and dry

    • Very wet but warm

    Correct Answer
    A. Warm and dry
    Explanation
    Being warm and dry reduces the risk of suffering from hand-arm vibration. Cold temperatures can cause vasoconstriction, reducing blood flow to the extremities and making them more susceptible to vibration-related injuries. Additionally, wet conditions can further increase the risk as moisture can enhance the transmission of vibrations. Therefore, being warm and dry helps to maintain proper blood circulation and minimize the negative effects of hand-arm vibration.

    What are three early signs of vibration white finger?

    • Temporary loss of feeling in the fingers

    • The fingertips turn white

    • A skin rash

    • Tingling in the fingers

    • Blisters

    Correct Answer(s)
    A. Temporary loss of feeling in the fingers
    A. The fingertips turn white
    A. Tingling in the fingers
    Explanation
    The three early signs of vibration white finger are temporary loss of feeling in the fingers, the fingertips turning white, and tingling in the fingers. These symptoms are commonly experienced by individuals who are exposed to excessive vibration, such as those who operate vibrating machinery or tools. The temporary loss of feeling in the fingers is caused by the constriction of blood vessels, leading to reduced blood flow. The fingertips turning white is a result of the blood vessels constricting and limiting blood supply to the area. Tingling in the fingers is a sensation caused by nerve damage due to prolonged exposure to vibration.
