Commercial Diving

Commercial divers perform a variety of tasks underwater, from maintenance and repair to scientific research. Some examples of commercial diving work activities include inspecting the condition of a bridge or a vessel’s hull, clearing a propeller, repairing sewer pipes, and photographing marine life. As of 2015, there were an estimated 3,450 commercial divers in the United States¹. These divers span multiple industries due to the wide range of jobs and skills, and are mostly concentrated in states sharing borders with an ocean or the Great Lakes, performing both inshore and offshore dive operations².

Commercial divers are exposed to a variety of marine hazards, including drowning, respiratory and circulatory complications, and hypothermia, which can be worsened by the number and length of dives, physical demands of diving, and limited visibility underwater. Age, physical fitness, and experience of the divers are suggested to be associated with these health effects. Further, divers are exposed to hazards similar to those working in construction while performing certain work activities, such as welding, operating heavy equipment, and working with power tools^2-3.

The Bureau of Labor Statistics reported 310 nonfatal occupational injuries and illnesses among commercial divers involving days away from work during 2011–2015⁴, and an additional 25 fatal occupational injuries during 2011–2014 (with the number of fatalities for 2015 not yet available)⁵.
