After a fire involving a building or industrial structure, there are often multiple types of damage to the building materials. Knowing how heat affects various building materials can be helpful in determining the level of damage to building components.
In Part II we discuss how using our Scanning Electron Microscope (SEM/EDS) helps answer important questions as to how a steel part harvested from the tongue of a failed trailer hitch broke, and what was the cause?
With the phasing-in of Subchapter M to the towing vessel community, operators are faced with a decision: use the ‘Coast Guard option’ and be inspected by the United States Coat Guard (USCG) or use the ‘TSMS option’ and be inspected by an independent company?
Geothermal power pulls hot water from deep within the earth to heat and vaporize a fluid that is then used to drive a turbine-generator. In this post, we discuss a case study and solution related to a vaporizer tube leakage at a geothermal energy plant.
As you may recall, in parts one and two of the blog series we discussed several preventative steps you can take to extend the life of your HVAC system. But, there is one last and very important area to be checked on your HVAC system:::- the refrigerant charge.
There are admittedly times when HVAC service calls are unavoidable. However, in today’s discussion, we hope to reveal some practical ways to try and avoid unnecessary service calls, whenever possible.
For most of us, seasonal maintenance on our home’s HVAC system is not a priority. The majority of homeowners use their HVAC system until a component fails. Understanding the basics of how our home’s HVAC system functions can help us to prioritize our HVAC maintenance.
In our first post (part 1) we discussed equipment ratings and location definitions (what is a dry or wet location). In our last post (part 2) we discussed equipment that is not made to get wet, yet for some reason it does and what do you do. So, what happens when the Authority Having Jurisdiction...
In our last post we discussed equipment ratings and location definitions (what is a dry or wet location). In this post let's discuss equipment that is not made to get wet, yet for some reason it does. Does this mean it needs to be thrown away and a new one purchased? No, of course not.
It has been common in the past to assume that water and electrical equipment do not mix. However, just because a piece of electrical equipment, such as an electrical panel or a computer, gets wet doesn't mean that it needs to be replaced.
It is common knowledge that freezing water can fracture pipes; however, did you know it can also save the day?
Diesel engines are a rugged and reliable choice for propulsion and power generation. In applications where electricity is not available or may be disrupted, a Diesel engine is a good choice for providing an alternative to an electric motor for pumps. Why, then, do so many Diesel engines with...
Smoke detectors are a critical element for fire safety and have been found to reduce the risk of dying in a home structure fire by 54%. In this blog, we talk about two common types of residential smoke detectors and the importance of having them in your home.
Last year, EDT posted a blog on Ballast Water Management, and the intent of the article was to provide a synopsis of ballast water and regulations which affect the operation and equipment onboard ships. This blog is an update to keep you informed of new legislation and changes in regulations.
What is an Arc-Fault Circuit Interrupter (AFCI) and how does it work? AFCIs are microprocessor-controlled devices that continuously monitor the voltage and current flowing in a circuit and interrupt the current flow if an arc is detected, and have been required as part of the National Electrical...
