You’re Just Not My Type – Part 1: Guards
February 2, 2026 11:36 am Leave a Comment
Selecting the best or most effective way to reduce or eliminate risk from a particular machine hazard is an extremely important process. It can mean the difference between someone going home and hugging their wife and children…to never going home again. The hazard control hierarchy (see figure below) is an available tool that illustrates what is known to be most effective to least effective when it comes to eliminating machine hazards or reducing the risk from those hazards to an acceptable level. Removing the hazard by designing it out is by far most effective. (more…)
CHECK OUT THAT RACK! – The Importance of Inspecting Storage Racks for Proper Installation
November 5, 2025 1:36 pm Leave a Comment
People have too much “stuff”. Manufacturers, retailers, wholesalers, and commercial enterprises all carry inventory of “stuff”, too. According to the Energy Information Administration’s (EIA’s) own statistics, in 2018, the US had over 17.4 billion ft² of warehouse and storage. Growing from just 13 billion ft² in 2012, warehouse and storage space is the fastest growing and now the largest use of commercial space in the US, overtaking office space for the first time in modern history.

Almost every one of those buildings contains storage racks. And this doesn’t include the mercantile spaces. You can go to a big box retailer and buy cereal from a lower shelf while pallets of grain or packaged drinks sit 20-30 feet above, waiting to be introduced to the customer.

There is no specific OSHA regulation for anchoring storage racks – (more…)
Stop or I’ll Soot!!!

Fire. Something about fire touches our brainstems…both good and bad! Uncontrolled fire is terrifying and deadly to be sure. But the controlled burning of wood at a campfire or in a fireplace in your home almost can’t be beat, to my mind! For that very reason, a fairly common amenity to houses nowadays is the gas log fireplace insert.

When not installed properly, these logs will generate soot. These soot particles can leave the fireplace and meander. All. Over. Your. House. (more…)
KEEP the CHANGE?
October 2, 2025 9:44 am Leave a Comment
As we all know, change is a part of life. Sometimes the results from change are good. And we know sometimes change may result in things becoming worse, although it may not be immediately evident. I think it is safe to say that when we intentionally make changes to something, our goal is to make it better with respect to one or more metrics. Engineers working in manufacturing facilities are often asked to make changes to existing machines and processes for multiple reasons: (more…)
Structure Fires in Eating and Drinking Establishments
September 14, 2025 4:17 pm Leave a Comment
Eating and drinking establishments see an average of 7,410 structure fires per year based on a 2017 report published by the National Fire Protection Association (NFPA). The report analyzed available data from the U.S. Fire Administration’s National Fire Incident Reporting System (NFIRS) and the NFPA’s annual fire department survey for the years 2010-2014.

Spontaneous Combustion…Is it hot in here or is it just me???
September 10, 2025 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…)
Hidden Heat: The Unseen Hazard of a High Resistance Connection
12:04 pm Leave a Comment
A typical residence can have upwards of 10,000 feet of electrical conductors installed, most of which are buried in the walls, attics and crawlspaces. A commercial building can have 100,000 to upwards of 1 million feet of electrical conductors. At each device such as a switch or a receptacle are at least three, and typically six or more connections of these conductors within a junction box. The connections can be in the form of twisted connectors, screw terminals, push in terminals and crimped connectors.

Waterpark Woes
August 4, 2025 11:34 am Leave a Comment
On July 12, 2024, a family entered the local water park to cool down. The family consisted of a mother and her two sons. While walking toward the wave pool area, the mother stepped off the wooden stairs and onto the surrounding concrete landing. As she did so, she slipped on a puddle of water that had accumulated on the surface. She fell backward, landing on her left side and striking her elbow and the back of her head against the stairs—effectively ending the family’s outing before it began. (more…)
Water Removal In Windows and Doors – Part 3: Sill Risers
July 7, 2025 10:47 am Leave a Comment
Welcome back to my multi-part series about water resistance in windows and doors. Last time we discussed weatherstripping. Today, we move on to a product common to sliding doors and coastal areas – sill risers.

Sill risers offer a brute force way to reduce water infiltration when a LOT of water is expected to hit a fenestration product. Unlike weathersealing, buried drainage, or weep systems, sill risers block water by providing a dam. Coastal homes with wind driven rain frequently have sill risers. They are practical and require less maintenance than weep holes or buried drainage systems, plus (more…)
Machine Guarding Resources
June 26, 2025 8:33 am Leave a Comment
So, you find yourself with a machine hazard that you need to guard. Where do your turn for guidance regarding guards? Several resources are available for the person who is tasked with providing machine guarding.

The United States government provides resources in the Code of Federal Regulations (CFR). These can be found at www.ecfr.gov. Title 29 of the CFR, section 1910 covers “General Industry” regulations. 1910 Subpart O, covers Machinery and Machine Guarding. Definitions are covered in 1910.211 and it is wise to understand how terms are defined. For instance, in 1910.211(a)(1), Point of operations is defined by the regulation as “that point at which cutting, shaping, boring, or forming is accomplished on the stock.” (more…)
