Most mechanical devices such as fans, pumps, etc. produce vibration.. Vibration is easily transmitted through solid materials and may ‘appear’ elsewhere producing troublesome vibration and/or noise.. VIBeUsers ManualiiWarrantyNewport Corporation warrants that this product will be free from defects in material and workmanship and will comply with Newports published specifications at thetime of sale TB-RS-SHE-202-001 . ver1.04. What is Hand Arm Vibration (HAV)?. It is caused in industries associated with heavy or vibrating machinery. Examples - road breakers, rock drills, hand held grinders, electric hammer drills etc.. How Can I prevent it?. Use low vibration tools.. Try a different approach to your job.. Use the right tool for the job.. Keep blades and cutting edges sharp.. Reduce grip and pressure, allow the tool to do the work.. Health Protection Team. January 2022. Occupational Health Hazards. About Hand Arm Vibration. A presentation by Wood.. 2. 1. What is Hand Arm Vibration?. 2. What are the health effects of Hand Arm Vibration?. Hand-Arm Vibration Syndrome (HAVS) is a common occupational medicine condition caused by exposure to hand-arm vibration from the use of hand-held vibrating tools or hand contact with vibrating work su ��2 is such that, in the absence of special circumstances, the attribution of particular cases to the nature of the employment can be established or presumed with reasonable certainty.Th CONTENTS.
