He and Ohorilko cleared the broken glass and pulled people through the window frame, one at a time. Neither one remembers how many people they rescued, but Lowell Fire Department investigators say eight people from two families, the Kaweres and the Silveras, were displaced by the fire.
Soon, city firefighters arrived, and the fraternity brothers stood back. Kieran DeLacy, a junior mechanical engineering major from Reading, Massachusetts, and a member of Omicron Pi, saw that several of the fire victims huddled in the street were shivering in their pajamas.
I'm using an "old" 300D (Rebel) together with a Sigma EM-140 DG ring flash and a Sigma 50mm macro lens in my orthodontic practice. Sometimes the flash does not fire, even if it did a couple of seconds before, without any modifications made on body, lens or flash. Mostly it continues to work if I open the battery compartment of the flash to reset the circuits. But even this works inconsistently.
Can only say I had a sigma 500Superdg flash that started exhibiting very similar symptoms (whilst under guarantee) - sent it back to sigma and they sent me a new flash- think it's one of the circuit boards going. I'm assuming here that it has behaved normally in the past ?

Time is the biggest enemy once a fire has started and escape plans help you get out of your home quickly. In less than 30 seconds, a small flame can get completely out of control and turn into a major fire. It only takes minutes for a house, apartment or dorm to fill with thick black smoke and become engulfed in flames.
When you come to a closed door, use the back of your hand to feel the top of the door, the doorknob and the crack between the door and door frame to make sure that fire is not on the other side. If it feels hot, use your secondary escape route. Even if the door feels cool, open it carefully. Brace your shoulder against the door and open it slowly. If heat and smoke come in, slam the door and make sure it is securely closed, then use your alternate escape route.
Designate a meeting location away from the home, but not necessarily across the street. For example, meet under a specific tree or at the end of the driveway or front sidewalk to make sure everyone has gotten out safely and no one will be hurt looking for someone who is already safe. Designate one person to phone the fire department.
Remember to escape first, then notify the fire department using the 911 system or proper local emergency number in your area. Never go back into a burning building for any reason. If someone is missing, tell the firefighters. They are equipped to perform rescues safely.
On Saturday, the Fire Department responded two separate times to the property for fire alarm activations. After the second alarm, fire crews entered the residence to determine if there were any safety issues.
Amber J. Soja earned her PhD in Environmental Sciences from the University of Virginia, Charlottesville, VA in January 2004. She is currently an Associate Research Fellow at the National Institute of Aerospace and is resident in the Climate Science and Chemistry and Dynamics Branches of Atmospheric Sciences at the NASA Langley Research Center. She has 25 years of research experience in using remotely-sensed and GIS data to explore the interactions between fire, the biosphere, and atmosphere, as our weather and climate change. She has taken part in and led numerous interdisciplinary, national and international field campaigns that investigated satellite-defined fire behavior and emissions, and the feedbacks between fire, the biosphere, weather and climate, primarily in remote Siberia (e.g., FireBear, INTEX-A, INTEX-B, TexAQS, ARCTAS and FIREX-AQ).
In the early 1990s, US West was an organization that was leading the charge in telecommunications. At the time, their buildings were being plagued by disruptive false fire alarms. How it was dealt with is a great example of how to apply the Six Sigma quality improvement process, a method applicable to nearly any quality issue that you might be having in your organization.
One such area was false fire alarms. At first glance, this might seem like a rather innocuous concern. However, when one takes into account how disruptive the panic that comes with an alarm can be and how evacuating a research facility could completely undermine the work being done, it becomes clear that dealing with such an issue would be a necessity if it were a regular occurrence. Considerable costs could come with such an occurrence, as could the possibility of not meeting deadlines, production goals, or even failing to meet customer expectations.
The first thing that Arthur and the building manager did was look at the available data about the false fire alarms. From a quality improvement perspective, they looked at the rate of fire alarms per month using a control chart. Next, they examined this data with a Pareto chart. With the chart, they looked at what each false alarm incident throughout the past year was attributed to. Seven of the incidents were attributed to faulty detectors: two more to the likelihood of cell phone interference, one to water damage, and one to dust particles settling in the detector.
Another idea that was being floated throughout the building was that the use of the microwave was leading to the alarms. Some staff thought that the false fire alarms had to do with the detectors being set off whenever someone was microwaving some popcorn. The proximity of the detectors and the number of different detectors throughout the building going off every year gave little credence to this particular theory.
At the same time that this was all going on, the local fire department was also experiencing a significant increase in false fire alarms that they were having to respond to. This particular fire department was serving an area that was unique in that many of the businesses in the vicinity were research facilities that were experimenting with new technology. The false alarms were having an effect, in some cases, of the fire department being able to respond adequately to real fires. So, what was happening over in US West was proving not to be isolated. There were no reports of detectors having a recall or widespread defect or being reported as being faulty in areas that were not known for being technology hubs, so the culprit of the alarms began to emerge through deductive reasoning.
Entering the cell phone theory into a fishbone diagram, they asked why a cell phone might be causing the alarms. Cell phones emit a frequency when engaged, so this could be causing radio frequency interference. As far as why this would be an issue with fire alarms, it was suspected that it could be because they had unshielded detectors.
A key practice when encountering an issue at your organization is to take the time to examine all of the available data. In doing so, Arthur and the building manager were able to see what the most likely cause was of the alarms, especially after finding out about the local fire department having the issue widespread throughout its service area of the tech hub and remembering the details of the auditorium incident.
Since replacing all of the detectors was a cost-prohibitive solution, Arthur and the building manager had to find another option. A solution that would cost the company virtually nothing turned out to be simply making the building cellular-free. This nearly eliminated the false fire alarm problem.
Sir Arthur Conan Doyle had a famous line in one of his books about Sherlock Holmes. The line says that if you eliminate the impossible, whatever is left, however improbable it may be, must be the truth. When looking at the potential causes of the fire alarms, the microwave popcorn theory was quickly discredited. Also, the chance of all of the alarms being attributable to water damage throughout the year did not appear possible. Faulty detectors seemed unlikely, given that there were no product recalls and that the problem seemed isolated geographically to the technological research area. Particle dust also came across as not being a possibility, if looking at the similar frequency of various detectors being set off in all areas of the building.
False fire alarms in a business may seem like a small problem, but they could have a ripple effect just like any other issue. How Arthur and the building manager approached the problem is a great example of how to apply the Six Sigma quality improvement process to any issue that might be present in an organization. With their way of identifying the problem, measuring and analyzing the data, implementing improvements, and controlling the results, it is also a clear example of intuitively utilizing DMAIC, a cornerstone of the Six Sigma method.
Normal Fire Chief Mick Humer believed the insurer sent anelectrical engineer to examine the attic and electric panel. Thefire was limited to the attic, but water and smoke damaged the restof the building at 711 Kingsley Court, No. 2.
