Improperly Used Space Heaters Can Be Dangerous
October 1, 2022 2:28 pm Leave a Comment
As the temperature outside slides from the cold to the “bitter” cold range on the thermometer, most people tend to turn the heat on inside their home. Some homes, however, do not have whole house heat or sufficient heating capacity and therefore the occupants may rely on portable space heaters. Portable space heaters, used properly, can be a good choice to warm a small area of a home. Unfortunately, while they can warm your cold and tingling hands and feet, they can also warm nearby materials to the point of ignition. (more…)
Scared of Water, or Prefer to Get Drenched? Fire Suppression with Preaction and Deluge Systems
August 29, 2022 2:11 pm Leave a Comment
In my two previous blogs, we first discussed wet sprinkler systems (Wet), the most basic and most common fire system type followed by dry sprinkler systems (Dry), which are a bit more complicated. Ratcheting up another level, in this last edition on sprinkler systems, let’s take a look together at preaction and deluge systems. These can be complex and variable, so we’ll operate at the 30,000 ft level. (more…)
When a DRY Fire Sprinkler System Leaves You Soaked
July 1, 2022 2:13 pm Leave a Comment
In my previous blog , I discussed the most basic and most common fire system type: wet sprinkler systems. The possible failure areas discussed with wet systems will also apply to dry sprinkler systems (control valves closed, obstructions, issues in the system, installation, or deficiencies with inspection, testing, and maintenance). Dry systems are even more prone to obstructions than wet systems, so close attention should be paid to that possibility. (more…)
When a Fire Sprinkler System Fails to Deliver
March 31, 2022 11:04 am Leave a Comment
After a major fire, it is necessary to investigate the fire sprinkler system to see if and why it malfunctioned. Wet sprinkler systems are the most common and least complex fire sprinkler systems in use. The following are major items addressed in an investigation involving a wet system.

If available, drawings of the supply piping and sprinkler system are helpful. If these are not available, a sketch of the system will be made. Requests will also be made for inspection, testing, and maintenance documentation as well as fire alarm logs.

The top reason that fire sprinkler systems do not function correctly during a fire is (more…)

Heating System Losses: Part Two
January 12, 2022 9:28 am Leave a Comment
Previously, Warren posted the first installment of a series on losses associated with heating systems. The first article looked at central forced air furnaces. This new article will look at a common form of supplemental or secondary heat, oil filled electric radiant heaters. These heaters are commonly used to provide extra heating in areas that are lacking in central heating capacity. Another rationale for their use arises from manufacturer’s claims that the portable heating units can lower your power bill. This is based on (more…)
Spontaneous Combustion…Is it hot in here or is it just me???
August 13, 2021 3:08 pm Leave a Comment
In the old-timey Fire Triangle, you have heat, fuel, and oxygen. Get these three together in the right quantities, and you get fire. What if the fuel provides its own heat? That’s spontaneous combustion, or spontaneous ignition. NFPA921 defines this as “initiation of combustion of a material by an internal chemical or biological reaction that has produced sufficient heat to ignite the material.” (more…)
Improper Hearth Extension Leads to Structure Fire
March 25, 2021 3:54 pm Leave a Comment
The fire service affords you the opportunity to witness and observe things that a lot of engineers and even most people do not get the chance to see. An example of this is the situation where extended elevated temperatures combined with poor construction techniques to result in a structure fire.

I have personally observed several occasions where a structure fire was initiated due to improper construction of the fireplace hearth extension. The most recent one followed a multi-day cold snap, at least by South Carolina standards. The thermometer read 17 degrees F as I drove to the call of smoke in a residence (more…)
Proper Construction and Maintenance Can Prevent Deadly Chimney Fires
February 16, 2021 1:52 pm Leave a Comment

There are few things as comforting to me during the winter months as a warm fire burning in the fireplace. And in this case, I am talking the real deal, the kind that warms you multiple times; from cutting, splitting and stacking the firewood until finally lighting a fire in the fireplace. However, just like your parents taught you, fire can be dangerous. And having an actual fire in your home fireplace comes with some required maintenance to ensure you can safely control the fire and keep it where it belongs. (more…)
Residential Structure Fires
January 25, 2021 2:05 pm Leave a Comment
The winter season is well underway in the United States, with the Christmas and New Years holidays behind us and the depths of cold weather here for the duration. With winter, many people spend more hours indoors as compared to the summer when outdoor activities ramp up. With more time spent indoors, it is somewhat intuitive that the use of electricity would increase as well.

Electricity is one of the most influential utilities in our daily life. Much of what modern societies rely on to get through a normal day requires electricity. Have you ever been in a slight panic looking for an electric outlet when your cell phone is below 10% charge? Or how many times do we all attempt to turn on a light switch when we enter a room during a known power outage from sheer habit? Even our personal transportation which has relied on gasoline for roughly 100 years is shifting toward electric automobiles. (more…)
