This is because production methods, particularly in the aircraft industry, have required the increased use of portable grinding and riveting tools. Loriga (1911) first connected circulatory disturbances with the use of pneumatic tools, which had by then been in favour fo...
متن کاملComparative study of vibration disease among operators of vibrating tools by factor analysis.
Principal component analysis was carried out to determine the interrelationships between subjective symptoms experienced by workers using various types of vibrating tools (brush saws (41), rock drills (39), chipping hammers (42) and chain saws (49)) and control groups (clerks (44), farmers (42)). The characteristics of the patterns of common factors extracted from these symptoms and the frequen...
