All Oxy employees and contractors are required to follow these policies and take the necessary precautions to protect themselves and their co-workers.

Oxy consistently ranks among the safest companies in the United States.

Oxy’s 2012 employee IIR of 0.33 – the best in company history – is far less than the all-U.S. industry average of 3.5 reported by the U.S. Bureau of Labor Statistics.
