When Wet isn't Really Wet (Part 3)

Albert M. Rose, P.E.

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...

When Wet Really Isn't Wet (part 2)

Albert M. Rose, P.E.

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.

When Wet Isn't Really Wet (Part 1)

Albert M. Rose, P.E.

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.

Smoke Detectors

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.

Arc-Fault Circuit Interrupters (AFCIs)

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...

Condensate Drainage

To understand proper condensate removal, it is first important to have a working definition of the term condensate in the context of Heating, Ventilation, and Air Conditioning (HVAC). Most HVAC systems contain a form of refrigeration cycle which uses mechanical work acting on a fluid (in most cases...

Snow Loads

Jason M.K. Cochran, M.S., P.E.

Freshly fallen snow is often a beautiful and awe-inspiring sight to see. Some parts of the country may see new snow daily while other areas may only see it once a century. Regardless of how prepared our cities are, snow can have a great impact on our everyday lives, particularly on our structures...

Electrocution

Edgardo López, P.E., CFEI

EDT was asked to determine the cause of an electrocution of a pedestrian. The following information is a review of the case, and what EDT found to be the cause.

Computer Graphics

EDT

Computer graphics are visual communication tools to aid an audience in visualizing data in a clear and interesting manner, compared to text or oral communication alone. Within this article are examples of how EDT uses Computer Graphics for Forensic Engineering purposes.

Star Bolts

Have you ever noticed eye-catching stars positioned on the fronts of masonry row homes in urban areas, such as Philadelphia, New York, Baltimore, and various other cities? The stars are not just ornamental; they are also functional.

Hurricanes in Florida

Albert M. Rose, P.E.

Those of us who choose to live in Florida, expect the occasional hurricane. Some years are quiet while others are much more active. The discussion with respect to oncoming hurricanes is always: Do I evacuate or stay put and ride it out?

Stormwater, Among Other Things

Matthew E. Buckner, P.E.

Structures built within or encroaching on a floodplain can be expected to experience flooding conditions. Features such as Grading, stormwater management implementation, and water retention methods can be implemented during the design and/or construction process and can have considerable impact on a...
