Nurses are at greater risk than firefighters. In 2013 your nursing staff faced a 15% greater chance of spine injury than firefighters.
Check out the Bureau of Labor Statistics Table 18 posted below for the final tabulated 2013 rates of musculoskeletal injuries for full-time workers, compared by occupation. Firefighters—who lug heavy ladders, people, and equipment daily—had a rate of 232 per 10,000. For nursing staff, the total was 264 per 10,000 full-time RNs and nursing assistants. A spine injury can end a career in the blink of an eye.
