Pipe Ruptures Above Your CT Scanner - Now What?

By: Envista Forensics - Andrew Spetter and Mark Ewing

All is quiet at 10:30 pm until a nurse notices water on the 2nd floor hallway. Building maintenance is called and discovers a ruptured pipe fitting in a bathroom on the 2nd floor. The water is shut off at 10:45 pm but unfortunately the damage has been done. It is later discovered that water penetrated through perforations in the ceiling in the CT suite on the 1st floor exposing the 16-slice CT gantry and patient table to water.

Merging Carbon Monoxide Life Safety with Energy Conservation Methods

By: James Partridge

Residential indoor air quality, historically, has not been a major concern because the envelope and window leakage provided inhabitants with sufficient outdoor air. Older residential buildings are sufficiently leaky such that infiltration alone can meet the minimum outdoor air requirements for residential ventilation. In an increased environmentally conscious society, many individuals have become more aware of their resource consumption, and are implementing enclosure draftstopping, attic insulation, and window replacement.

Automated Retrieval System Failure Results in Catastrophic Fire at Storage Facility

By: Bill O'Donnell

The largest storage rack/ retrieval system, larger than two football fields and eighty feet wide was constructed to store 108 million pounds of paper products. On July, 2002, after two months of use, the facility collapsed and sparked a fire that destroyed the entire structure and 45 million pounds of paper. Nearly 50 fire departments responded to the inferno, which burned for three weeks. The owner of the facility sued a number of companies that included the contractor that designed and built the structure, a subcontractor, and the company that supplied the 110 foot steel columns.

Air Bag Deployment Criteria

By: Dr. Kenneth Solomon

Air bag control modules utilize complex algorithms to make air bag deployment decisions based on crash severity related to the change in vehicle speed or deceleration over time. Due to the proprietary nature of air bag deployment algorithms, the velocity, acceleration, or displacement thresholds for air bag deployment during a collision are not easily obtained; however, a range of frontal barrier impact speeds and corresponding deceleration and displacement threshold values for air bag deployment can be approximated using known vehicle stiffness-to-weight ratios.

General Motors Joins Yogi Berra

By: Dr. Kenneth E. Lehrer

Even with creative financing, accounting techniques and decreased profit margins, the American automobile industry appears unable to sustain itself and has suffered significant losses, especially in recent years. Given these realities, it would seem prudent to rely upon baseball and the one special feature they have enjoyed via compliments of a United States Supreme Court Decision in 1922, namely exemption under the Antitrust Laws, basically Sherman and Clayton Acts.

The Soul

By: Peter H. Dennis

We often hear people use the word "soul." They talk about "mind-body-soul", they might state that someone "has soul," they can point to a "poor soul," they may designate certain individuals as "soul mates," and they could talk about operating on a "soul level." What exactly are they talking about? Do they really know themselves? Are we a soul or do we have a soul? What then, is a soul?

Go Forth and Testify

By: Joe Samnik

At first blush you may think that this article is about a small, albeit ugly armored animal and you would be justified in doing so. After all, the name Armadillo Partners conjures up a mental image of a corporate holding of armadillos, presumably for sale. Such would not be the case however. In fact, this article is about an arbor area and trees located at a shopping center called Armadillo Square in Broward County, Florida.

Connected Vehicles and Autonomous Vehicles: Where Do ITE Members Stand?

By: Richard Beaubien

The topic of Connected Vehicles and Autonomous Vehicles is not new, yet advances in computing power, wireless capabilities, and soft ware development are taking implementation predictions from the not-too-distance future and placing them in the here and now. Emerging vehicle technologies foreshadow a world in which sensors and soft ware will replace humans in the driver's seat.

Buses and Motorcoaches: Humps and Bumps

By: Ned Einstein

I have often written about the impacts of overly-tight schedules as the primary causative factor in incidents - in fact, the underlying cause of perhaps half of them. Because speeding is one of the "cures" to this problem, one of its characteristics is the failure to slow down when the roadway surface is not, as jazz musicians say, "melody." One of the most common scenarios is to cruise over speed bumps and speed humps. Another is to fail to slow over rugged terrain, particularly potholes and the often dysfunctional patches that sloppy road crews create to "repair" them.
