11.   Gerald Poje, a member of the Chemical Safety and Hazard Investigation Board, agreed that the greatest fear is a cascade of equipment failures.

12.   He sent the helicopters, and there were equipment failures and a crash in a sandstorm, and men killed, and the mission was aborted.

13.   He speculated that the chemical reaction could have been caused by equipment failure.

14.   If the investigation points to an equipment failure, the case becomes more complex, with airplane and parts manufacturers, more lawyers and bigger liability policies involved.

15.   Investigators also thought it possible that equipment failure or human error caused the plane to crash as the pilot was trying to abort a landing in a driving rainstorm.

16.   Last year, ethylene prices rose sharply after explosions, floods and equipment failure at several major plants impeded ethylene production.

17.   Lack of spare airplanes and over-scheduling are the biggest reasons for chronically delayed flights, not labor disputes or equipment failures or air traffic control or weather.

18.   Only two were blamed even in part on equipment failure.

19.   Questioned repeatedly, Waddle said he had not explicitly discussed the equipment failure with any of his senior officers or ordered them to be more vigilant.

20.   Rookie drivers making mistakes, signal failures, lagging maintenance, and divided management are being blamed for the wave of accidents, equipment failures and shabby service.
