# Safety Engineering International (SEI)

> Safety Engineering International (SEI) is a vehicle safety engineering company headquartered in Goleta, California, specializing in rollover crash research, dynamic vehicle testing, and the design of the HALO Rollover Occupant Protection System, a state-of-the-art, patented, globally certified ROPS in use by major international companies.

SEI's design engineers have decades of experience in rollover accident investigation and dynamic vehicle testing. After determining that severe injuries in rollover crashes were primarily caused by A-Pillar and windshield header collapse intruding into the occupant compartment, SEI's principals designed and built the Jordan Rollover System (JRS) to dynamically test vehicles under real-world rollover conditions. Over 300 tests have been performed on more than 50 different vehicle types.

SEI developed and patented the HALO Rollover Occupant Protection System (HALO ROPS), a one-of-a-kind hybrid external and internal system with no visible interior roll bars, fully compatible with side curtain airbags, and available for more than two dozen vehicle models worldwide. HALO ROPS is tested to ISO 3471-2008 and FMVSS 216, patented in seven countries, and used globally by major companies including Anglo American, BHP Billiton, Bonatti, Caterpillar, Komatsu, Rio Tinto, Sempra Energy, TC Energy, and Vale.

SEI also provides consulting, fleet safety audits, and certified installer training to enhance safety across various industries.
