Page 14: 5.1 Risk Assessment
RISK ASSESSMENT 5.1 RISK ASSESSMENT Bear machines have been developed from machines that RJH Finishing Systems Ltd have supplied into the market place for many years and have an excellent safety pedigree. However, like all machines of this type they can be dangerous if used carelessly or incorrectly.
Page 15 SECTION FIVE RISK ASSESSMENT EJECTION OF PARTS/COMPONENTS is present with all grinding processes. Avoid applying excessive pressure or pressing sharp objects into the wheel as this will increase the risk of ejection and can result in wheel damage or even breakage. LOW RISK VIBRATION caused by the operation will be transmitted to the operator’s arm(s) and in extreme cases can lead to Hand Arm Vibration Syndrome.
