Don't Have a Pain in the Neck: Learn the Ergonomic Laws
Although technically a branch of bio-mechanical engineering science, ergonomics should be the primary art for construction workers.
Ergonomics is a branch of bio-mechanical engineering science applied to fit the workplace conditions and physical job demands to the biostructural capabilities and limitations of the worker, including all aspects of the worker's physical specifications, physiological behavior patterns, sociological attributes, repetitive labor effects, task organization, load duration, range of motion, material/equipment layout, coworker interaction, and gross environmental stress criteria. It's a relatively new field, with a lot of impure science, peculiar data variations and unsubstantiated findings.
Originating in 1949 during World War II, it endeavored to overcome the mechanical and performance failures of pilots due to human error, physical strain and fatigue encountered under wartime stress. Back then there was a war to be won and performing the best was the way to win it. Today, there are more than a few debates and arguments between our elected officials, scientists, labor unions and lawmakers when it comes to matching regulatory standards to scientific theory and safe, feasible
