EMPLOYEE KILLED BY JET PERFORATORS' DISCHARGES

At approximately 10:30 a.m. on November 17,1989, Employee #1 and another employe discharges which caused Employee #1's death. e, both engineers, were to build a carrier-type gun used to perforate oil-well c asings. When one carrier-end cap was viewed, it was noted it was a misfired gun because primacord was tucked into the carrier. The carrier had a jet perforator threaded on a strand of primacord. The blasting caps were connected at the well site. For an undetermined reason, the carrier was placed with an open-end floor, raised and bounced onto the concrete floor. While doing so a piece of the prima cord may have gotten to edge of carrier and when struck the impact set off the p rimacord and jet perforators. Employee #1 was in the way of the jet perforators'
