Preliminary data from the Bureau of Labor Statistics' Census of Fatal Occupational Injuries showed fatal work injuries increased by 2 percent in 2014 from the prior year, although the rate of 3.3 per 100,000 full-time workers stayed the same.

The preliminary total in 2014 was 4,679 fatal work injuries.

"Far too many people are still killed on the job – 13 workers every day taken from their families tragically and unnecessarily. These numbers underscore the urgent need for employers to provide a safe workplace for their employees as the law requires," U.S. Secretary of Labor Thomas E. Perez said in a statement.

Fatal falls, slips, and trips rose by 10 percent in 2014 from the previous year. Falls to lower level were up 9 percent to 647 from 595 in 2013, while falls on the same level increased 17 percent, according to BLS. And fatal work injuries due to transportation incidents rose slightly to 1,891 from 1,865 in 2013, with transportation incidents accounting for 40 percent of fatal workplace injuries in 2014.

Fatal work injuries due to violence and other injuries by persons or animals were lower in 2014, with 749 deaths in 2014 compared to 773 in 2013.
