The number of workplace deaths in the U.S. and Arizona declined in 2012, according to the preliminary National Census of Fatal Occupational Injuries report released by the U.S. Bureau of Labor Statistics last week.

In 2011, the agency recorded 4,693 fatal work injuries nationally. The new report showed that in 2012, that number decreased by about 300 to 4,383. The labor bureau said that number is the “second lowest preliminary total since (the report) was first conducted in 1992.”

In Arizona, data indicated there were 37 workplace fatalities in 2012, compared to the previous year’s 65.

The leading cause, both nationally and in Arizona, were incidents related to transportation.

Texas had the highest number of workplace deaths with 531, the report showed. Rhode Island had the lowest with eight.
