Accident: 508895 - Diver Drowns When Air Hose Is Severed

Employee #1, a scuba diver, was installing a shackle onto a fixed anchor line in approximately 120 ft of water when, for some reason his high pressure hose was severed in two and he drowned. Causal factors contributing to this accident: (1) both primary and alternate regulators were in need of repair; (2) there was no flotation equipment with an air source separate from the breathing air supply; and (3) there was no standby diver. In addition, Employee #1 was using borrowed equipment that was unfamiliar to him, he was not line-tended, and he was not carrying a reserve air supply.

Accident: 201140324 - Thumb Tip Amputated In Milling Machine

On May 21, 1997, Employee #1 was setting up a part in a fixture to prepare it for milling on a milling machine. This fixture had a pneumatically controlled clamp to hold the part in place. Employee #1 was holding the part in the fixture with one hand and trying to attach the air hose to the fixture with his other hand. As the air pressure activated the clamp, the tip of his left thumb was amputated. Employee #1 was taken to Anaheim General Hospital for treatment.

Accident: 14392138 - Diver Drowns When Air Hose Sucked Into Pump And Cut

At approximately 9:00 a.m. on May 17, 1997, Employee #1, a diver with a diving crew, entered the water at the Lady of the Isle Casino Water Vessel near Bossier City, LA. He was working on the port side, approximately 9 ft below the water surface, blowing silt away from the vessel with a two-nozzle jet gun and a hydraulic submersible pump. The pump was approximately 13 ft below the water, suspended from a crane boom that was situated on a nearby sandbar with the other diving equipment and personnel. At approximately 9:09 a.m., Employee #1's air/communication cable or hose was sucked into the impeller on the submersible pump and cut, ending communication between the diver and the crew on the sandbar. A standby diver entered the water, found Employee #1, and brought him to the sandbar at approximately 9:20 a.m. Employee #1 died at a local hospital. Hydraulic power to the submersible pump was cut off at the time contact was lost. The pump had several 8 in. wide openings at the top through which silt could enter to be pumped away. A rope guard had been installed by the crew to reduce the size of the openings, but the 2 in. diameter air hose could still be sucked in.
