Definitions: Mechanical Vibration means vibration occurring in a piece of machinery or equipment or vehicle when in operation. Hand - Arm vibration (HAV) means mechanical vibration when transmitted to hand-arm system that entails a health risk to the employee. Whole-body vibration means mechanical vibration when transmitted to the whole body entails a health risk to the employee. The Exposure Limit Values and Action Values in respect to the daily exposure limit values - standardised to an eight hour reference period - shall be: Hand Arm Vibration The daily exposure limit value shall be 5 m/s 2 The daily exposure action value shall be 2.5 m/s 2 Whole Body Vibration - The daily exposure limit value shall be 1.15 m/s 2 The daily exposure action value shall be 0.5 m/s 2 Workplace vibration risk assessments should include appropriate measurements i.e. the level and duration of exposure, including any exposure to impulsive vibration - from which a vibration control policy is implemented, to protect all workers at risk. The employer and department should retain a permanent record of the most recent vibration survey finding. Where measurements of vibration are taken they must be representative of daily personal exposure. This may be relatively straightforward where one is exposed to steady vibration levels for their full working day. However, in the case where workers are exposed to highly variable vibration levels for intermittent time periods, this may be quite complex and it is essential that to accurately assess the vibration employees effective exposure. Therefore, the need for the risk assessment requires planning and execution by a occupational hygienist. Records of measurements and other data must be kept for a period of 3 years. 18.46.2 HAZARDS It is well known that exposure to vibration can cause many health symptoms to employees using tools, equipment or machinery e.g. drills, grinders, jack hammers, saws, sanders, chipping hammers etc. - that transmit vibrations to the hand and arm or the whole body. Symptoms associated Hand-Arm Vibration include: Tingling or numbness in the fingers or toes Blanching (whitening) of fingers due to lack of circulation, with acute pain & flushing during recovery Reduced sensitivity to pain, touch and temperature. Chronic exposures leads to hands & fingers becoming numb and fingers becoming blue-black.. Gangrene is posible at a later stage. Disorders associated Hand-Arm Vibration include: Vibration White Finger damage caused to blood vessels from vibration causes them to collapse, preventing oxygen reaching tissues. It is often made considerably worse by low temperatures. Raynauds Disease: A disease in which people who may be pre-disposed develop symptoms similar to Vibration White Finger. It is not clear whether or not - vibration and cold alone - contributes to this disorder. The specific nature and location of these hazards are as set out in the Departmental Hazard Identification/Risk Assessment work sheets contained in Document No. 3 attached, e.g. the Departmental Hazard Risk Assessment (D.H.R.A.) 18.46.3 RISKS The risks associated with the aforementioned hazards are to be assessed by the Department (using the appropriate technical input where necessary). These assessments shall be carried out using: Check lists provided (where applicable) and Departmental Hazard Identification/Risk Assessment Work Sheets contained in Document No.3 i.e. Departmental Hazard Risk Assessment (D.H.R.A.). 18.46.4 ARRANGEMENTS AND CONTROLS REQUIRED As with most regulations covering health and safety, the main requirements on an employer can be summed up with the following: Identify sources and nature of vibration Assess the risks to the employees Control Reduce risk to as low as is reasonably practicable Implement - the control measures that are required Monitor The controls, the work/equipment creating the risk and the employees affected (health surveillance) Educate - Provide employees with adequate information, training and supervision. These hazards and risks will be minimised by the following arrangements and controls: There are many ways of reducing exposure to vibration often a combination of methods works best. First think about how to remove the vibration altogether, i.e. eliminate the source of the vibration. If that is not possible, do all that can be done to minimise the vibration at source. Identify departmental staff members whose tasks may expose them to this hazard List all hand held tools (make & model) and establish time used for these tasks Obtain vibration information from equipment manufacturers Assess equipment & machinery liable to be a source of vibration exposure Improve maintenance schedules on above equipment & machinery Introduce health surveillance where machinery or equipment are liable to cause hand, arm or whole body vibration Where applicable, introduce adequate staff training , information & instruction regarding vibration hazards Assess and measure vibration exposure to relevant employees, including tasks, work place conditions etc. This assessment to be carried out by a competent person using proper method and instruments. Where applicable, limit duration and intensity of exposure to mechanical vibration. Where applicable, establish appropriate work schedules with adequate rest periods Ensure provision of PPE & clothing to protect employees from exposure to cold & damp. Reduce exposure to the lowest reasonable practicable level. Take action when the Exposure Limit Values and Action Values in respect to the daily exposure limit values are exceeded or approached. 18.46.5 ARRANGEMENTS AND CONTROLS The details of the Arrangements and Controls in place and those required in the short, medium and long term, shall be set out by the Department in the forms provided in Document No.4 i.e. Departmental Safety Action Plan (D.S.A.P.). These Arrangements and Controls shall be reviewed and updated on a yearly basis. 18.13.6 RESPONSIBILITIES The following personnel are responsible in the Department/Office/Area for ensuring the implementation and ongoing compliance with the aforementioned arrangements and controls.
