The rate of nonfatal injuries and illnesses in the construction industry, including specialty trade contractors, ticked down slightly last year compared to the year before, according to data recently released by the Bureau of Labor Statistics (BLS).

Construction saw an incidence rate of 3.5 in 2015, down from a 3.6 rate in 2014. The rates represent the number of injuries and illnesses per 100 full-time workers in a given year, according to the BLS.

The specialty trade contractor category, which includes contract glaziers, brought down its incidence rate by the same amount, from 3.8 to 3.7. This continues a positive trend for the segment, as the rate in 2013 was 4.2. However, specialty trade contractors still maintain the highest incidence rate of the three major construction categories.

Meanwhile, the manufacturing industry decreased its incidence rate from 4.0 to 3.8 over the same span. The nonmetallic mineral product manufacturing category, which includes glass manufacturing, remained above the manufacturing industry average with a rate of 4.7 in 2015, though that is down from 5.1 from a year ago.

The fabricated metal product segment also decreased its incident rate year over year, dropping its mark from 4.8 to 4.7.

Overall, there were approximately 2.9 million nonfatal workplace injuries and illnesses reported by private industry employers in 2015, according to the BLS. This resulted in a rate of 3.0 cases per 100 equivalent full-time workers and continued a pattern of declines that, apart from 2012, occurred annually for the last 13 years.
