OSHA VPP Star Designation – Matrix Service

Matrix Service’s largest fabrication facility in Catoosa, OK,  is one of only two heavy metal fabrication facilities in the U.S. to achieve OSHA’s VPP Star status.  The highest designation given by OSHA, it is the most challenging of the category designations and indicates Matrix Service’s proven success in four interdependent areas:

  • Management leadership and employee involvement
  • Worksite analysis
  • Hazard prevention and control
  • Safety and health training

Receipt of this designation is a testament to Matrix Service’s employees’ commitment to maintaining a world-class safety culture and their focus on eliminating incidents all-together.
