Episode 9: Fysiske arbeidsmiljøfaktorer - vibrasjoner | Verneombudskurs

Discussion on the prevalence of hand-arm vibrations in Norwegian workplaces and the industries affected by vibrations.

Explanation of vibrations as mechanical movements from surfaces, machines, or other equipment, with vibration levels measured in meters per second squared (m/s2) and described in hertz.

Vibrations comprise movements in multiple directions, commonly represented in an axis system to differentiate between whole-body vibrations and hand-arm vibrations.

Differentiation between whole-body vibrations characterized by frequencies less than 40 Hertz and hand-arm vibrations transferred to hands and arms, typically caused by handheld tools and machinery.

Explanation of assessing vibration exposure over 8 hours, denoted as the daily exposure value (A(8)), and the importance of considering both frequency and acceleration in the evaluation.

Highlighting the requirements for providing training, information, and risk assessment under the Work Environment Act, Chapter 14, to address the health and safety risks associated with vibration exposure.

Discussion of potential health effects caused by hand-arm vibrations, including vascular, nerve, and musculoskeletal disorders manifested in various occupations.

Description of health symptoms such as white fingers, nerve compression, and reduced fingertip sensitivity due to exposure to vibrating handheld tools.

Overview of diagnosing hand-arm vibration syndrome using clinical tools and the detrimental effects of daily vibration exposure over a ten-year period, influenced by factors like smoking and work techniques.

Discussion on the effects of whole-body vibrations on the body, including motion sickness, spinal stress, and potential health risks associated with prolonged exposure.

Recommendations for organizing work, selecting appropriate machinery, maintaining equipment, and ensuring proper machine operation to mitigate the risks of vibration-related health issues.

Exploration of conducting risk assessments for whole-body vibrations, including the option of measurements for assessing mechanical vibration exposure.
