A program was undertaken to identify problems associated with logging operations which result in work injuries, to establish the scope and magnitude of these problems, and to make recommendations for reducing work injury rates. Historic data on logging injuries was obtained. Existing standards for dealing with logging occupational safety were reviewed. Observations were made of representative logging operations. Evidence suggests that the disabling work injury rate has lessened in recent years. Concurrently, the injury severity rate has not changed, although the average number of days lost per disabling work injury has increased. Some of the existing standards were not worded in ways that the individual logger would understand or be able to implement. In other cases, particularly in the area of environmental protection, some of the regulations for protecting the environment actually recommended methods of logging which were more dangerous to the logger. The use of additional personal protective equipment, particularly of the lower extremities against saw cuts, has appeared to produce a major reduction in injury rate. The author's recommendations regarding improved worker safety, cover standards for occupational safety, good work practices, improved injury data collection, and training. Suggestions are also made concerning research into protective equipment design, occupational diseases, and energy relationships. An extensive glossary of logging terms is included.
