How can you reduce hand/arm vibration in the workplace?

How can you reduce hand/arm vibration in the workplace?

Safe Work Practices Along with using anti-vibration tools and gloves, workers can reduce the risk of hand-arm vibration syndrome (HAVS) by following work practices: Use a minimum strength hand grip that still allows the safe operation of the tool or process. Wear sufficient clothing, including gloves, to keep warm.

How can hand arm vibration risks be managed?

∎ Isolating the hazard by changing the path the vibration takes to the worker’s hand e.g. on a grinder a rubber bush can be added to the side handle to reduce vibration being transmitted to the supporting hand. The choice of material for the rubber bush will be important in working out which vibration is reduced.

How can the risk of HAVS be reduced?

Clothing. Provide your employees with protective clothing when necessary to keep them warm and dry. This will encourage good blood circulation which should help protect them from developing vibration white finger. Gloves can be used to keep hands warm, but should not be relied upon to provide protection from vibration.

What is the most preferred method to reduce the vibration from hand held tools?

To reduce the risk of hand-arm vibrations, you can opt for screwdrivers with automatic air or power shut-off, which have vibration levels of less than 2,5 m/s2, which is the limit established by Italian law (D.

How are vibrations measured?

Vibration is most commonly measured using a ceramic piezoelectric sensor or accelerometer. An accelerometer is a sensor that measures the dynamic acceleration of a physical device as a voltage. The benefits of an accelerometer include linearity over a wide frequency range and a large dynamic range.

What are the control measures of manual handling?

Manual Handling Control Measures

• Avoid the need for manual handling.
• Reduce the load risk by using lighter weights or more stable containers.
• Reorganise the activity or environment to further reduce the impact on the individual(s)
• Utilise mechanical lifting aids or equipment.

How do you treat HAVS?

In general, HAVS is irreversible and there is no effective treatment or cure. Medications can sometimes be effective in reducing the frequency and severity of blanching attacks, and anti-inflammatory medications can be used to reduce pain symptoms.

How is Vdv calculated?

VDV is calculated as the root mean quad of the acceleration and is more sensitive to peaks in acceleration than the root mean square acceleration. This gives a result in m/s1. 75. Weighting factors of 1.4 apply on the x and y axes.

How do you control HAVS?

8 Top Tips for Preventing Hand Arm Vibration Syndrome (HAVS)

1. Stay warm, don’t get warm. It is a lot less work to keep fingers warm compared with getting already-cold fingers warm.
2. Stay dry.
3. Block the wind.
4. Take care of your core.
5. Avoid tight clothing.
6. Watch your grip!
7. Add heat.
8. Keep work places warm and dry.

What are the three signs of hand arm vibration Havs?

Early symptoms

• Tingling Fingers. One of the first signs of HAVS you might notice is tingling in your fingers or hands.
• Numbness. You might get a sense of numbness, like a dead leg, but in your hands and fingers.
• Loss of strength.
• White finger.
• Permanent numbness.
• Loss of grip.
• Advanced vibration white finger.

What is the need of vibration measurement?

Vibration may influence the durability and reliability of machinery systems or structures and cause problems such as damage, abnormal stopping and disaster. Vibration measurement is an important countermeasure to prevent these problems.

How many people are exposed to hand arm vibration?

Based on a 1974 study of occupational exposures to vibration, NIOSH estimates that 1.2 million workers in the United States are potentially exposed to hand-arm vibration (Table 2). 5 These workers are potentially at risk of developing vibration syndrome. Table 2. Workers Potentially Exposed to Hand-Arm Vibration Adapted from reference [ 5]

What should you do about hand arm vibration?

Wherever there is exposure to hand-arm vibration, above the EAV, you should be looking for alternative processes, equipment and/or working methods which would eliminate or reduce exposure or mean people are exposed for shorter times. You should also be keeping up with what is good practice for vibration control within your industry.

Can a vibration hand tool cause vibration syndrome?

In light of a recently completed, comprehensive study, conducted by the National Institute for Occupational Safety and Health (NIOSH), the Institute concludes that vibrating hand tools can cause vibration syndrome, a condition also known as vibration white finger and as Raynaud’s phenomenon of occupational origin.

Who are the control group in vibration syndrome?

Workers in the foundries and the shipyard who had never used vibrating hand tools comprised the control group. Workers in the exposed groups were in the same work locations as the control workers, and were exposed to vibrating hand tools while on the job.
