            Our company recently had an incident where someone was operating a scissor lift and hit a fire sprinkler with it. The sprinkler activated, and the area flooded. Fire sprinklers activating, unfortunately, isn’t that uncommon in the electrical, construction, and HVAC trades, but it’s preventable with proper training and attention to detail. Those of you who […]

            Being in an industry that requires a lot of travel—local or regional—can be a great thing for people who enjoy driving. It also comes with several more risks and opportunities for roadway accidents than someone who just has a round-trip commute to a single location every day. We’re all aware of the issues of texting behind […]

            I hear the following phrase a lot: It's the amperage that will kill you, not the voltage. While there is truth to the statement, it is sort of like saying, “It's the size of the vehicle, not the speed that kills you when it hits you.” OK, so that's a pretty bad example, but hopefully, […]

            Just like Shrek, I like to think about the heating sequence of operations as an onion—it has layers. And each layer builds upon the previous one. We have written previously in great detail about gas furnaces, from top to bottom. I want to focus today on why there is a sequence of operations and how […]

            Some of the scariest practices that occur in the field surround brazing practices and tank and regulator handling. A few obvious tips are: Store tanks completely secure and upright with nothing nearby that can easily open or damage the tank valve. NEVER store tanks in a torch kit with it off only at the torch […]

             In this short podcast episode, Bryan covers some unique electrical cases: when 0v isn't safe. When you measure voltage, you're finding out the electrical potential between two points. Just because there is 0v between one point and another doesn't mean there will be 0v between those points and other points. Non-contact voltage detectors are […]

             In this short podcast episode, Bryan talks about fire sprinklers and how to avoid setting them off on job sites. Fire sprinklers have an element in the center that expands when exposed to heat (like a TXV sensing bulb) and breaks the glass. When the glass breaks, the fire sprinkler starts pouring out water.
