Natural Disaster. By many measures, logging is the most dangerous occupation in the United States. The tools and equipment such as chain saws and logging machines pose hazards wherever they are used. As loggers use their tools and equipment, they deal with massive weights and irresistible momentum of falling, rolling, and sliding trees and logs. The hazards are more acute when dangerous environmental conditions are factored in, such as uneven, unstable or rough terrain; inclement weather including rain, snow, lightning, winds, and extreme cold and/or remote and isolated work sites where health care facilities are not immediately accessible. The combination of these hazards present a significant risk to employees working in logging operations throughout the country, regardless of the type of timber being logged, where it is logged, or the end use of the wood. Exposures to hazards in logging are addressed in specific standards for the general industry. See more from topic source: https://www.osha.gov/html/a-z-index.html
