As the weather turns cold, many people use fireplaces to provide supplemental heat. The warmth from a fireplace is a comfort and the aesthetics of a glowing fire are a pleasure. However, there is nothing pleasurable about a residential house fire that results from an improperly built or used fireplace or chimney. Read More
A large agricultural trailer had been connected to a truck using a clevis pin with a spring locking clip. The trailer became disconnected from the truck and collided with an oncoming vehicle. The trailer was in poor condition, did not have safety chains, and had substantial recent modifications by the owner. Read More
Emergency generators are often called into service during catastrophic events like hurricanes, floods, tornadoes or fires, but also during more mundane events like thunderstorms and other things that may temporarily interrupt the public power grid. Can you rely on your generator to perform at those critical times? Read More
In May, 2014, a plant farm worker was seriously injured when he fell into the hopper of an electrically powered soil mixer. The mixer in question used a rotating steel ribbon powered by a 7-1/2 hp electric motor to mix batches of materials such as sand, mulch, wood shavings, fertilizers and other landscaping materials to create potting soil. At the top of the hopper sidewalls, within 6 inches of the ribbon, was a steel grate. Read More
In November of 2010, a miner was injured by a roof bolting machine (roof bolter) in an Alabama underground coal mine. The roof bolter in question had undergone a complete rebuild intended to return the machine to the original equipment manufacturer’s (OEM’s) specifications. Warren was hired to analyze both the design of the roof bolter and the actions of the rebuilder to determine if either contributed to the unfortunate coal miner’s serious injury. Background information on coal mining and roof bolters, as well as an analysis of the roof bolter and the actions of the rebuilder are included. Read More
In our last post on 3D scanning, we introduced Warren’s new Faro Focus X 330 three dimensional scanner. To recap, the Faro scanner combines three dimensional laser measurement with automated photography to capture 360-degree data from the real world. Potential applications include vehicle accident scenes and damaged vehicles, structural collapses, fire scenes, flood damage scenes, and machinery and equipment analysis, among others. In this post, we will highlight some of the outputs that can be created from the detailed data captured by the scanner. Read More
We at Warren are pleased to announce our recent purchase of a Faro Focus X 330 three dimensional scanner with FARO Scene image processing software. The scanner takes up to 976,000 data points per second and can scan objects at distances to 1000 feet. The scanner forms a point cloud of millions of data points while also capturing 360 degree panoramic photographs. By combining a series of scans, a three dimensional representation can be created that enables precise measurements, animations, and demonstrations. The scanner can capture imagery indoors, outdoors, and even in darkness. Read More
As an experienced safety consultant, I have investigated many incidents in my career in which a worker “falls through an opening.” The majority of these incidents have occurred at construction sites and most resulted in serious injury or death. Read More
Periodically, Warren Engineers and Consultants are asked to perform inspections that require work at raised elevations. Typical jobs and tasks include climbing on commercial and residential roofs with steep pitches, working on scaffolding, climbing from one level to the next at a fire or industrial loss scene, riding in the buckets of lift equipment, and inspecting exterior structural elements such as windows and masonry.

Industrial ovens and furnaces are used in many manufacturing processes. One use of industrial ovens is for drying and curing coatings on fabrics.
We investigated a fire loss involving a very large oven, 10 stories high, used for curing coatings on an industrial fabric. A young firefighter was burned in response to this fire, one of a string of many fires that had occurred involving the oven.
