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...

The Meeting Point - Human-Machine Interfaces (Part 1)

Can a poorly designed user interface lead to a large loss? You better believe it. Have you ever hit the wrong button on the remote control, or had trouble getting a device to work correctly because it was left in the wrong mode? Thankfully, these sort of mistakes are just mild annoyances, but when...

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.

Fractures (part 1)

Our Scanning Electron Microscope (SEM) is capable of 100,000X magnification, allowing a close-up look at material surfaces for defects, inclusions, and fracture characteristics. By using a SEM/EDS to study the surface of the fracture, the question of how the part broke - or the mode of fracture -...

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.

New Safety Services for Towing Vessels

EDT

EDT is pleased to announce that the firm has been approved by the United States Coast Guard as a third party organization (TPO) under Subchapter M, a federal regulation that establishes safety standards for towing vessels like tugboats and towboats.
