2 Agenda Hand-arm Vibration Tool handling and selectionAlternative methods Hilti Product Selector Dust Noise Working at Height Start by listing the above subjects that will be covered in this training programme.
3 Current legislation European and national laws regulate exposure of workers to both physical and chemical agents It is the responsibility of the employer to ensure that these laws are adhered to MB (14,367,744 bytes) To comply with legislation, in general employers must: Design out risks where possible Inform workforce of health & safety risks Assess the risks Provide an actionable solution Deliver training to employees Keep health and action records This applies to the four key areas of risk: The different areas of risk are covered by different regulations – either National or European. It is the employer‘s responsibility to comply with these regulations. All legisltation placed on employers can be summarised by the six points highlighted, this applies to all four areas of risk – Hand-arm Vibration, Dust, Noise and Working at Height.
4 Health & Safety: Four Key Areas of RiskHand-arm Vibration Dust Working at Height Noise
5 Basics of Hand-Arm VibrationMost handheld power tools transmit vibration to the hands and arms. Over exposure to vibration can result in Hand-Arm Vibration Syndrome (HAVS). Each year, HAV accounts for approximately 3,000 new claims for Industrial Injury Disability Benefit, the greatest number being in the construction industry. This has led to an incremental increase in insurance premiums. All tools have a Vibration Magnitude, which is measured in m/s2 and must be monitored on a daily basis by an employer. Exposure Action Value (EAV: 2.5 m/s2): The level that can be worked to without any health surveillance in place. A tool with a vibration magnitude of 2.5m/s2 or below can be used for an 8 hour day without any risk HAV is still the most important area of risk to the GB construction industry. Exposure Limit Value (ELV: 5.0 m/s2): The absolute maximum level allowed, below this, but above EAV, additional controls such as health surveillance must be in place All vibration monitoring systems offer transparency to exposure to hand-arm vibration with relation to EAV and ELV
6 Reducing the Risk of HAVS: Tool Handling – Drilling and BreakingHold tool in a stance which allows good balance Hold tool below shoulder level where possible Restrict the contact pressure to a level where the tool function most effectively Always grip both handles and restrict grip force just sufficient to hold tool securely Just because it doesn’t shake, it doesn’t mean that it won’t work Let the tool do the work Explain: Holding the tool with both hands and keeping a good body balance reduces the risk of wrist injuries. Exerting too much grip force or contact pressure does not increase the performance of the tool. Applying too much grip force increases vibration transmission to the hands. Setting the depth gauge ensures optimum drilling time. Some tools have been designed with exceptional operator comfort, this means that the user would feel much lower vibration, however, the performance is higher. Do not use the vibration feeling as a measure for performance.

8 Reducing the Risk of HAVS: Tool Handling – Cutting & GrindingAlways use low vibration side handle Ensure that you have been trained to use grinders and you have a valid certificate Reciprocating Saw - an alternative method to grinding Clamp adaptor reduces vibration Hilti grinders come with low vibration side handle. These have been designed to reduce vibration. Always use grinders with original handle. Explain the choice of the correct disc for the job minimises vibration Important Notice: “Reciprocating Saws provide an alternative to grinders in areas where sparks may be an issue or hot work permits are required. Vibration is at its lowest when the tool is used with pipe clamp adaptor.
9 Reducing the Risk of HAVS: Use the correct consumables - drill bits designed for higher speedWatch out for signs of wear and tear Worn out bits increase drilling time and therefore increase exposure to vibration. Use the right drill bit, blade or abrasive disc etc. as per the product selector. NOT USING THE INSERT AS STATED IN THE PRODUCT SELSCTOR WILL NULLIY THE VALUES GIVEN Check wear mark as shown in the diagram in the case of TE-YX.
10 Reducing the Risk of HAVS: Use the correct consumables - chisels with longer life and optimum performance Longer and consistent performance chisels Worn out bits increase drilling time and therefore increase exposure to vibration. Use the right drill bit, blade or abrasive disc etc. as per the product selector. NOT USING THE INSERT AS STATED IN THE PRODUCT SELSCTOR WILL NULLIY THE VALUES GIVEN Check wear mark as shown in the diagram in the case of TE-YX.
11 Reducing the Risk of HAVS by offering alternative MethodsDrilling Light Duty Drilled Fixings Breaking Mechanical Scabbling Conventional method Diamond coring Direct Fastening Wire Sawing Grinding Alternative
12 Reducing the Risk of HAVS: Alternative MethodsDirect Fastening to replace light duty drilled fixings Wire sawing to replaced mechanical breaking Grinding surface preparation to replace mechanical scabbling Diamond drilling is a low vibration method of hole drilling Where vibration can be eliminated throughn use of alternative methods, thes should be considered. Here are some of the alternatives which are available Direct Fastening Shot firing technology, without the need to drill. As shot firing is an impact “pulse” action, vibration, in the frequency range that causes HAVS, is not produced. The existing guidelines on vibration tools do not apply to Direct Fastening tools. Wire Sawing Cuts through concrete quickly and with no hands on form the operative, to replace using a mechanicl breaker Diamond Drilling Hole drilling with a fixed rig is fast, accurate and with substantially lower vibration for the operator Grinding of surfaces Special grinding discs produce a scabbled finis to better mechanical scabbling with substantially less vibration ML Channel In many cases, standard struts can be substituted by lightweight channels that are easier and quicker to cut which reduces cutting and grinding times significantly. As a result the grinders are used for less time hence HAVS risk is reduced. Lightweight channel system

14 Reducing the Risk of HAVS: Hilti’s unique productivity-based Tool SelectorProductivity figures Noise level Dust removal Consumable HSE Points
15 Reducing the Risk of HAVS: Combining HSE Points with ProductivityThe best possible way of measuring exposure to vibration Valuable planning tool when coupled with the HSE points calculator The example shows how the HSE points system can be used to calculate an operator’s exposure to risk from vibration over a working day. It can either be used through the day or as a planning tool, which is where the new HSE Points Calculator comes in. Productivity figures provide the best planning tool and are the most user friendly and accurate method of measuring exposure to risk from vibration Coupling these with the HSE points system enables customers to calculate employees exposure to risk through more than one application per day In addition to being a valuable planning tool, the Hilti HSE Points calculator can be used to combine risk from Hilti tools with other manufacturers tools Brought together this means we can offer the best possible tool for monitoring risk from vibration

34 Health & Safety: Key Areas of RiskHand-arm Vibration Dust Working at Height Noise
35 Reducing the Risk of NoiseLoud noise can cause permanent damage to your hearing. Once you loose your hearing, you will never recover it A European directive has been issued to protect workers from exposure to excessive noise: The Physical Agents (Noise) Directive The slide identifies the regulations surrounding noise. Again noise is difficult to measure and the interface between tool and material will more than likley produce more nosie than the tool itself. What we discuss later is that Hilti now make all nosie values transparent so they can ve used for rsik assessment, but we would alwasy recommend the use of ear protection.
36 Reducing the Risk of Noise: What do employers need to do?Inform and train their workforce about Noise and the associated risk How they can protect themselves What measures the employer has taken Provide suitable protective equipment for their employees’ use Assess and manage the risk Define who has what risk level Provide health surveillance for their employees where risks cannot be eliminated Consider alternative methods and job rotation The risk assessment must be recorded by the employer and kept up to date
37 Reducing the Risk of Noise: What should workers do?Report any signs of hearing damage immediately to their supervisor. Symptoms are: Difficulty following a conversation, also on the phone The family often complains that the TV is too loud Tinnitus (constant ringing, whistling or humming) in the ears may also be a sign Use the right kind of ear protection: There is a wide variety of ear protection available Pick the one best suited to the applicable job Consider alternative methods Consider alternative methods of doing the job, e. g. Diamond drilling instead of chiselling Direct fastening instead of drilling
