Now four firefighters have filed notices of claim, indicating they may take legal action against the municipality for negligence and violation of the city's own fire code.

Among the allegations is that there were no smoke detectors in firefighters' sleeping quarters, contributing to unspecified injuries to the firefighters when the two-alarm fire broke out at 1:27 a.m.

Although one smoke detector did activate during the March 2, 2015, fire, it was improperly installed and did not go off until flames broke out, rather than when the rags were in the smoldering stage, according to the claimants' documents, obtained by The Salt Lake Tribune through an open-records request. The firehouse at 270 W. 300 North did not meet code for such buildings, they say.

A City Hall spokesman said the municipality does not necessarily agree that the claims are accurate. But Matthew Rojas added that he could not be specific in his response and was limited by the threat of potential litigation.

The Fire Station No. 2 blaze was caused by oily rags, according to all four claimants — the third of four such fires at Salt Lake City Fire Department facilities since 2011, according to the document. It was the second fire at Station No. 2; the first one broke out there April 8, 2013.

Fire Station No. 2 had previously undergone about $1 million in renovations in 2011 — work that Hoffman said was improperly performed.

The brush truck is valued at $104,323.

Pryor Creek Fire Chief Tim Thompson said he is very grateful to Giles.

"It's been a huge benefit to this community and this area. We're blessed to have that type of people in our community."

But the broken water main created a sinkhole, which then snared the truck according to District Chief Stephan Powell of Toronto Fire Services.

The hobbled truck was eventually towed away. It's not yet known if it was damaged. No one was injured.

It happened as the fire truck was responding to an earlier two-car accident on I-40, just east of the Donelson Pike exit.

No firefighters or paramedics were hurt when the truck was hit, because they were away from it attending to the initial crash.

The fire truck was drivable but did sustain damage and firefighters planned to remove it from service for repairs.

According to a paramedic on the scene, the truck was new and just put into service in December.
