A number of changes and/or clarifications are included in this new Machinery Regulation, not the least of which is the definition for “substantial modification.” (more…)
Did you know that I’m passionate about fire protection? Instead of proving it with stories recounting soakings by numerous fire hydrant, fire pump, and deluge system tests, I will share more about fire sprinklers! (Working on solidifying my fire sprinkler nerd status!)
Automatic fire sprinklers have an over 150-year history, with Henry S. Parmelee being credited with (more…)
Did I lose you in the title? Fire alarms! Ah, those mysterious systems required by, discussed in, and described by hundreds of pages of sometimes baffling and circular code text. They can be intimidating to think about. Have you considered that these mysterious red boxes could have information helpful in a loss? Let me describe why it could be advantageous to have a knowledgeable person to check out the fire alarm system after a loss, and not just for fires. Just as an airplane’s black box may hold information (more…)

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…)
A proper collision scene documentation, lovingly referred to as a scene doc, will make or break the investigation… guaranteed! While not necessarily all inclusive, here are a few evidence collection / documentation techniques that have served me well over the years.

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…)
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…)
