Fox News (Memphis, Tennessee) produced a news story that gives light on the differences between Ionisation and Photo Electric smoke alarms. They also carry out an experiment to illustrate the performance of smoke alarms.
In my view the experiment was VERY POORLY conducted and full of inaccurate statements. For example they tried to demonstrate a SLOW SMOULDERING fire by setting fire to news paper and timber a tin bucket. This is NOT a slow smouldering fire!!!
Then they conducted a FAST FLAMING fire using a pan fire with a likely alcohol or petrochemical accelerant.
Google Trends is a service provided by Google to where you can compare the world's interest in your favorite topics. Google Trends also shows how frequently your topics have appeared in Google News stories, and in which geographic regions people have searched for them most.
Google Trends works by analysing a portion of Google web searches to compute how many searches have been done for the terms you enter, relative to the total number of searches done on Google over time. Then Google displays the search results as a graph plotted on a linear scale.
So your intrepid blogger decided to see what was more popular a Smoke Detector or a Smoke Alarm....
A terrible tragedy occurred early this morning here in Melbourne, when a man died in a home fire that the fire brigade believe was caused by a discarded cigarette.
Cigarette likely cause of fatal house fire
Fire investigators believe a fatal house fire at Heidelberg Heights, in Melbourne's east, was caused by a discarded cigarette.
A 56-year-old man died in the front room of the Wordsworth Avenue home about 2:00am.
Metropolitan Fire and Emergency Services Board spokesman Bob Undy says smoke alarms in the house were working when the fire started.
"The smoke alarms had melted off the roof but being the early hours of the morning, it was unfortunate no-one else heard the alarm," he said.
Smoke detectors or Smoke alarms are important safety devices, because of their obvious potential to save lives and property. There are two types of smoke detector commonly available in many countries.
One type uses the radiation from a small amount of radioactive material to assist in the detection or presence of smoke particles. These "ion chamber smoke detectors" are popular, because they are low power, inexpensive and are sensitive to a wide range of fire conditions.
