  1. The Life of a Smoke Alarm – How A Decade Flies!

    Leave a Comment

    A smoke alarm milestone birthday party!

    No kidding, I’m passionate about fire protection!  To prove it, I could tell you stories about the damage I have seen from various failures from freezes to fire pump cooling to what happens when a fire hydrant’s weep holes are clogged…. But instead, I will tell you about smoke alarms!

    Although it’s still new in my head, my home just turned 10 years old. The decade has seen the replacement of two household appliances and at least one HVAC repair… now what? A paint and décor refresh?  Maybe, but that’s not what the fire protection engineer is thinking! It’s time to replace the smoke alarms! (more…)

  2. Materials in HVAC Plenums

    Leave a Comment

    What materials are suitable for installation in Heating, Ventilation, and Air Conditioning (HVAC) plenums?  Let’s first define a plenum.  The 2021 edition of the International Mechanical Code (IMC), a subset of the International Building Code (IBC), defines a plenum as “an enclosed portion of a building structure, other than the occupied space being conditioned, that is designed to allow air movement, and thereby serve as a part of an air distribution system.” (more…)

  3. In Cahoots – Interconnections of Fire Protection Systems with Ancillary Equipment

    Leave a Comment

    Fire protection is an expanse that I am both fascinated by and passionate about. To prove it, I could show you my sprinkler collection… the old ones, the new ones, the sizes, the features!  But instead, I will share some information to show you the relationship between fire protection systems and other systems that you may have never thought about!

    Fire protection, suppression, and alarm systems often do not act alone. They can be in cahoots with life safety systems or other equipment or building systems to mitigate fires and help firefighters. Many, but not all, of these functions are associated with fire alarm systems. Many, but not all, of these functions are customary and expected. Some of these functions will automatically reset when the alarm or system is reset, but not all! (more…)

  4. Dig into Underground Fire Water Piping and Appurtenances

    Leave a Comment

    Many sites that are protected by fire sprinklers will have at least some amount of private underground fire water piping. Its purpose is to make water available for fire protection or suppression at a needed flow and pressure. Its presence is usually quietly evidenced by the connected objects that occasionally surface along its course, like valves, fire department connections and private hydrants, termed appurtenances. Underground water piping commands attention, though, when (more…)

  5. FORKLIFT Etiquette: DON’T BE A LOUSY TIPPER!

    Leave a Comment

    That is always good advice to follow if you are a forklift driver!  Operating a forklift can be a dangerous occupation.  There are approximately 1 million forklifts (powered industrial trucks) in the US workplace today, and it is estimated that just over 10% of those are involved in some type of accident every year.  Forklift accidents result in dozens of deaths and thousands of non-fatal injuries annually.  About one out of every four of those accidents involves a tipping or overturning forklift, making this the most common type of industrial truck accident.  (more…)

  6. Understanding Heat Transfer: A Guide for Fire Investigators

    Leave a Comment

    In the realm of fire investigation, understanding heat transfer is crucial. Heat transfer plays a significant role in how fires start, spread, and ultimately, how they can be analyzed and investigated. There are three primary modes of heat transfer: conduction, convection, and radiation. In this article, we’ll delve into each of these modes and explore examples of how fire investigators can apply this knowledge to their work. (more…)

  7. Dive Into Suction Tank Issues and Inspections

    Leave a Comment

    Privately-owned water tanks supplying fire protection systems have a long history. The NFPA published the Standard on Gravity Tanks in 1909. It is one of the oldest NFPA codes, predating even the Life Safety Code’s precursor, the Building Exits Code, first published in 1927. The Standard on Gravity Tanks evolved over the years to become NFPA 22, Standard for Water Tanks for Private Fire Protection. The inspection, testing, and maintenance requirements for all types of private fire water storage tanks are laid out in NFPA 25, Chapter 9 – Water Storage Tanks. While there are about eight different types of fire water tanks, I’d assert that the most common type today is the steel suction tank. (more…)

  8. A Primer On The Elements Of Fire Protection Water Supplies

    Leave a Comment

    Get primed!

    Fire protection water supplies can be made up of one or more common elements, including tanks, pumps, water sources and water systems. Sometimes elements are used together to develop an adequate supply for fire protection.

    An adequate water supply for a fire protection system will meet the needs of the fire protection system (plus safety factor) in three terms: (more…)

  9. Hot ’til It’s Not Part II – Heating System Maintenance

    Leave a Comment

    As cold weather sets in for those of us that actually get a winter in the Northern Hemisphere, a property owner needs to think about another expensive home system that is often taken for granted, your HVAC system.

    Whether you have a heat pump with electric backup, a gas fired furnace, a fuel oil fired furnace, or even  electric strip heat, your heating system requires some routine attention to maximize efficiency and get the most life out of the unit.

    As a homeowner, the easiest and cheapest thing you can do to maximize the efficiency of your heating system is (more…)

  10. Turkey Fryers- Product Design is Critical to Consumer Safety

    Leave a Comment

    As the holiday season nears, thoughts turn to wonderful home-cooked meals with family.  Few things in life are more pleasurable than a traditional holiday turkey feast. Yet for an unfortunate few, holiday meal time can turn tragic if a turkey frying accident occurs.   While fried turkeys may be tasty, many fire safety experts feel that the reward is not worth the risk.  (more…)
