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 13.7 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:

Health & Safety: Four Key Areas of Risk Dust Hand-arm Vibration Noise Working at Height

All tools have a Vibration Magnitude, which is measured in m/s2 and must be monitored on a daily basis by an employer. Basics of Hand-Arm Vibration Most 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. 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 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

Reducing the Risk of HAVS: Tool Handling – Drilling and Breaking • Hold 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

Reducing the Risk of HAVS: Tool Handling – Cutting & Grinding • Always 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

Reducing the Risk of HAVS: Use the correct consumables - drill bits designed for higher speed • Watch out for signs of wear and tear

Reducing the Risk of HAVS: Use the correct consumables - chisels with longer life and optimum performance • Longer and consistent performance chisels

One last thought on dust… Dust_chamber.avi

Reducing the Risk of Noise • Loud 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

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

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

Reducing the Risk of Working at Height • Falls from Height remain the biggest single cause of workplace deaths and one of the main causes of major injury • Hilti offers a comprehensive range of tried and trusted systems to you reduce your exposure to many of the risks of working at heights.
