A report released Thursday finds that firefighters battling last year's seven-alarm fire at the former Deutsche bank building faced a perfect storm of neglect and error by the FDNY, Department of Buildings, and contractors.

The Fire Department report spells out communication breakdowns and numerous fire hazards, including a broken standpipe, blocked stairwells, plastic sheeting and poorly marked exit signs.

Veteran firefighters Joseph Graffagnino and Robert Beddia died while fighting the fire last August.

The 176-page report, which was written by safety chiefs investigating the blaze, details how the firefighters made more than 14 "mayday" and 19 "urgent" distress calls, many of which could not be heard because of chatter on the portable radios.

"Some messages were not being received, other people were speaking over them," said Fire Commissioner Nicholas Scoppetta. "And it's very important when a mayday is given that everybody stop transmitting and let the officer hear the mayday and where it's coming from."

Firefighters, according to the report, also waited nearly an hour for water – spending 20 minutes believing the standpipe was working and another 20 minutes fixing the standpipe to get water on the fire. The report says that firefighters also had problems getting enough oxygen while trapped in the building.

"If we knew that the standpipe wasn't working, we'd have done everything necessary to be sure that we could get water on the fire before you send people up into close proximity," said Scoppetta.

The report also says a construction worker waited 13 minutes to call the Fire Department after finding the fire, which fire officials believe was caused by a discarded cigarette.

Scoppetta said that the report finds that DOB did not complete mandatory inspections when they should have, which, he says, would have made a huge difference in the FDNY's response.

"The key fact here is that there were not inspections," said Scoppetta. "You just can't lose sight of that. If we had done the inspections, we would have fought that fire in a very different way and we would not have run into these extremely difficult situations, such as no water and blocked stairwells."

The father of one of the fallen firefighters said the report still leaves many questions unanswered.

“Who told the fire department not to go in there for two years?” said Graffagnino. “Who told the DOB not to go in there for whatever time period they weren't in there? Where was all of these half a dozen safety teams that was supposed to be throughout the building yet no one was there?”

On Thursday, the Manhattan District Attorney's office was still deciding whether to charge the contractors, and possible even the city, in connection with the incident. That decision will come out at the end of next month.
