Vibrations hand-arm

There are some disorders of the distal upper extremity that should not be predicted by the strain index, such as hand-arm vibration syndrome (HAVS) and hypothenar hammer syndrome. 

These Regulations are designed to protect persons from the risk to their health and safety of the effects of exposure to vibration. There are two types of vibration, hand-arm vibration (HAV) and whole-body...

Exposure of the whole body to vibration (usually through the feet/buttocks when riding in a vehicle). Whole body vibration may increase the risk for injury, including low back pain and internal organ disruption. See also Ergonomics Segmental Vibration (Hand-Arm Vibration). 

Other hazards include heat stress within the protective suit, hand-arm vibration, slips and... 

For several decades, the International Organization for Standardization (ISO) published several standards for shock and vibration of equipment. ISO also published standards for human exposure to mechanical vibration and shock. One standard addresses hand-arm vibration syndrome (HAV). Another addresses whole-body vibration (WBV).

The first notation means that two fingers on the left hand show Raynaud s phenomenon in stage 2, and the injury involves one finger on the right hand with severity mild , i.e., stage 1...

Efforts toward international standardization have led to a document (ISO 5349 1986) containing guidelines for the proper measurement of hand-arm vibration exposure. In an informative addendum, which is not part of the standard, a model is proposed for the recognition of the risk of developing WF. Based on a...

Stonemasoning is an occupation related to multiple health hazards. Stonemasons work in big workshops, mostly unheated at wintertime. They handle heavy loads, causing back injuries. They are exposed to noise and silica dust. To reduce exposure to crystalline silica dust, they use wet methods to keep the dust down. They use powered hand tools that cause hand-arm vibration. 

Stonemasons are at risk of hand-arm vibration when using chipping hammers, angle grinders, drills, disk cutters, air rammers and abrasive wheels. Vibration-induced vasospastic disease, such as vibration white finger, or bone and joint disorders, such as carpal tunnel syndrome, are the most common diseases [8-10]. Damage to blood circulation, nerves and muscles may influence occupational skin disease.
