Recommendations and good practices in arctic open pit mining based on the Vibration:

 

There are many actions that can be done to reduce the risk of vibration damage. These measures may be technical or organizational. What action has the best effect obviously depends on how the work is carried out in the workplace. It is therefore of great value to the risk assessment to determine what factors and elements that give rise to vibration exposure.

It is very important to have a holistic approach when the measures implemented to prevent risks so that the influences on other factors not worsen, i.e. noise, ergonomics, dust and fumes. We have divided action examples in three parts. The first one, what the employer can implement, and second and third include measures for hand-arm vibration and whole body vibration.

1. Examples of measures that employers can implement:

• Avoid the operations that give rise to considerable vibration exposure.

• It is more effective to reduce the vibration exposure by reducing vibration magnitude than reducing the time.

• Limit the vibrations by changing maintenance of the object.

• Question about working with vibrating machinery is really needed.

• Obtain equipment with a holistic perspective where factors such as exposure to vibration, ergonomics, efficiency, etc. included.

• Compare the manufacturers declared values ??when purchasing, in order to select a low vibrating machine.

• Be aware that some low vibration machines have limited effectiveness, which in some cases can mean a greatly extended service and thereby perhaps even a higher total vibration exposure.

• Find contact with other mines where similar work is performed to exchange experiences on vibration mitigation measures. Often there is a good overall knowledge of the industry that may be utilized.

• Discuss with employees, safety representatives and supervisors about what you can do together to reduce the risks. Give them access to the risk assessment that has been conducted.

• Encourage work in natural posture and designing workplaces and operations ergonomically.

• Post work breaks, and switch if it is possible with other operations where no vibration exposure occurs.

• Train staff in using technology that provides a low vibration exposure.

• Inform that smoking and snuff causes contractions in blood vessels, which means an increased risk of vascular damage in the hands.

• Maintain equipment regularly, especially the parts that affect the machine's vibrations.

 

 

HAND-ARM VIBRATION

  • Follow instructions on correct machine handling
  • Make sure your machines are correctly maintained

–     Replace worn grinding wheels and worn tools

  • Let the machine do the job

–     The more force you use, the more vibrations are transferred to your hands and arms.

–     Take short breaks regularly

  • Work in a natural posture

–     assist in the ergonomical design at your work place.

  • Use tool-support when possible
  • Do not run the machine idle unnecessarily

–     Change work tasks often

  • Stay warm and dry

–     Use gloves in cold climate

–     Avoid cold machines

  • Avoid tobacco to prevent white fingers
  • If you are working with hand-held vibrating tools you should be offered a suitable health surveillance.

–   Talk to your company`s health care services or to your supervicer if you are exposed to vibration

 

 

WHOLE BODY VIBRATION

  • Follow instructions on correct machine use
  • Adjust seats and handles for better comfort
  • A suitably chosen seat and a vibration-absorbing cab can lower vibration

–     Adjust the seat for your weight

–     Make sure you know how vibration absorbing devices, like shock-absobers and suspensions, are functioning

–     Choose wheels that are approriate for the terrain

–     Check tire pressure

–     Drive on smooth ground and roads

–     Maintain roads

–     Avoid bumpy areas

–     Avoid speed that cause selfpulsation

  • Do not run the machine idle unnecessarily
  • Work in a natural posture

–     assist in the ergonomical design at your work place

–     Adjust controls so you easily can reach them

–     Take short breaks out-side the vehicle regularly

–     Change work tasks often
