Timber industry

Logging industry (occupational health) - the branch of the forest industry for the extraction and primary processing of wood. Logging for industrial purposes consists of the following manufacturing processes: tree-felling, successfully works, timber floating, catching him, storage and shipment to the enterprises-customers.
Basic operation when felling is the file tree trunks using gasoline or electric saws. Adverse factors in this process is the noise (see) middle-frequency nature and local vibration (see). During chainsaw work in the area of breathing workers come exhaust gases, the most adverse component of which is carbon monoxide (see). The introduction of the rational regime of work and rest (10-minute breaks after 45 minutes files), heated hands, warm baths and massage of hands after work significantly reduced the risk of vibration disease.
Lebedike engaged by winches hauling (skidding) trees are exposed to noise average frequency. Tractor skidding tractors are exposed to dust generated during Podmoskovnie fallen trees, mid-frequency noise of the diesel engine and jerky vibrations of different frequencies. Delimbing carried out either manually or with the help of electrosockets, generating high-frequency vibration. In the cold period of the year, logging workers may be exposed to low temperatures and intensive movement of air, and in the summer the bites of mosquitoes and mosquito.
Prolonged exposure to vibration and noise can cause vibration disease (see) and hearing loss (see). Poor nutrition in the conditions of cutting areas can lead to diseases of organs of digestion. The workers who perform logging, more often than workers in other professions, there rheumatism (see), scoliosis (see) the lumbar part of the spine with deforming spondylosis the (see).
Basic health measures when harvesting are: further mechanization and automation of production and processing of wood, improvement of mechanized tools and machines, improvement of the conditions of food and water at logging sites and provision of qualified medical assistance.

The logging industry is a sector of the forest industry for the extraction and primary processing of wood. In the USSR harvesting is done mostly mechanized. Adverse is hygienically factors when felling trees with chainsaws are noise midrange nature and vibration. Sources of noise: motor, gear chainsaw. Vibration sharply varies in frequency and amplitude. Felling trees gasoline chain saw is accompanied by release into the zone of breathing work of exhaust gases contain carbon monoxide, products of incomplete combustion of gasoline. In recent years, new models of petrol saws, which allowed to reduce a vibration on the handles 10-12 times, and reduce the noise at work and to divert exhaust fumes from the breathing zone of the worker. Developed and implemented by the rational regime of work and rest of workers: 40-45 minutes sawing and 10-minute breaks, which also contributes to the prevention of vibration disease.
The conditions of work of lebedeko engaged in Podmoskovnie (skidding) trees, are characterized by significant nervous tension and noise impacts mid-frequency spectrum. Tractor skidding tractors are exposed to dust, adverse weather conditions, mid-frequency noise from the diesel engine intensity varies depending on the type of a tractor, the speed and mode of operation. The great value has vibration complex (jerky low and high frequencies from the engine). In some logging enterprises stump branches produce elektrotechnische, generating high-frequency vibration.
The workers of the logging industry can be observed: vibration disease (see), professional hearing loss (see), diseases of digestive organs, vegetariani lower extremities, rheumatic diseases, scoliosis lumbar region with deforming spondylosis.
Health activities: further mechanization and automation of process of extraction and processing of wood, improvement of mechanized tools and machines, improvement of the conditions of food and water on the cutting areas, and ensuring that qualified medical aid. Role in the prevention of occupational diseases are preliminary and periodic medical examinations. Cm. also the Wood industry.
