Park officials testified that smoke alarms had been installed, but the park was unable to control vandalism to them and decided not to reinstall them after 1979. A park official testified that having an employee assigned to walk continually through the attraction was a good alternative to the smoke alarms. A top fire-safety official testifying for the defense said that sprinklers and smoke detectors might have saved part of the structure, but would not have saved lives because by then "you would have had lethal combustion products throughout the facility" suffocating the victims. His testimony was later criticised by other fire-safety experts as undermining efforts to advance sprinkler legislation.
