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…)
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…)
Don’t Get Burned With Your Gas Grill!
June 13, 2025 10:00 am Leave a Comment
If there is one thing Americans can agree upon, it is the enjoyment that comes from an outdoor barbeque. Whether a summertime cookout or a fall BBQ to watch a football game, we all love the fun and fellowship that comes from sharing a meal that was prepared outdoors on a grill or smoker. In fact, 64% of Americans own a grill or smoker. The great majority of these are LP fueled gas grills with comparatively few natural gas fired grills. These products can be enjoyed safely when designed, installed, and used in a proper manner. However, given the grill’s use of flammable fuel gas and high temperatures, the potential exists for things to go wrong and result in burn injuries or uncontained fires that spread to the surroundings.

Fire Sprinkler History and Development

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…)

How Fire Alarm Information Can Fill in a Loss Puzzle
February 17, 2025 12:04 pm Leave a Comment
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…)
The Potential Leak in Your Kitchen Cabinet – Flexible Supply Connectors
January 22, 2025 8:57 am Leave a Comment
One of the more innovative products to emerge on the plumbing scene in the past 20 years or so (in my opinion) is the flexible supply connector. A lot of people have seen but probably not paid much attention to them under their sink or perhaps from the toilet supply valve to the toilet tank. Most have (more…)
More HVAC Equipment Changes on the Way
January 14, 2025 9:13 am Leave a Comment
The United States Department of Energy (DOE) finalized energy efficiency standards for residential gas furnaces in late 2023. These new standards are slated for implementation in late 2028. The last time the DOE raised the efficiency rating of gas furnaces was in 2007, when the minimum efficiency for gas fired furnaces was raised from 78% to 80% efficient.

Let’s look at what efficiency means in this context. In simple terms, (more…)
New Year, New HVAC Refrigerant
December 12, 2024 9:30 am Leave a Comment
As we ring in the new year 2025, a significant change is coming for several heating, ventilation, air conditioning and refrigeration (HVACR) systems that are currently used in both residential and commercial applications. The 2020 American Innovation & Manufacturing (AIM) Act is bipartisan legislation that was signed into law. The AIM legislation empowers the Environmental Protection Agency (EPA) to reduce the production and consumption of hydroflourocarbons HFCs by 85 percent by the year 2035. (more…)
Safety Distance in Machine Safeguarding
December 4, 2024 9:06 am Leave a Comment
Hazard can be defined as a potential source of harm. Machine safeguarding seeks to protect people from these potential sources of harm. Often distance from a hazard will play a key role in providing a means of protection.

One would often think of distance as it relates to the location of a barrier guard from a hazard. ANSI B11.19, Performance Criteria for Safeguarding, defines safety distance as “the distance a safeguard is installed from a hazard such that individuals are not exposed to a hazard.” An example from ANSI B11.19 of the recommended distance of a slotted opening in a barrier guard from a hazard is shown (more…)
