Donaldson Enterprises Inc. has been cooperating with authorities investigating the explosion at an underground bunker Friday, killing five men and injuring another.
The bunker remained sealed yesterday as the focus of the blast turned to the company that stored fireworks inside the bunker in the worst accident of its kind in the islands. While Donaldson officials are not speaking to the media, Honolulu Fire Department Capt. Terry Seelig said, "They're cooperating (with investigators) as far as I know. They'll definitely be part of our interviews."
Fire investigators had no preliminary cause for the explosion and fire as they continued their "slow, methodical investigation," Seelig said.
Donaldson had a Certificate of Fitness for explosives and pyrotechnics issued by the Hawaii Occupational Safety and Health program, Department of Labor and Industrial Relations spokesman William Kunstman said.
The explosion is being investigated by various federal, state and local agencies, and additional investigators with experience in mine explosions might be arriving from the mainland, Kunstman said.
