The first boiler with a safety valve was designed by Denis Papin of France in 1679; boilers were made and used in England by the turn of the 18th century. Early boilers were made of wrought iron and riveted; as the advantages of high pressure and temperature were realized, manufacturers turned to steel and welding was accepted by the ASME Code in the 30’s.
Oil spills and leaks happen, particularly in structures that deal with the storage, transport, or processing of oil products. Contamination can occur through a variety of avenues, but the main concern when dealing with contaminated concrete (outside of the environmental issues) is whether the structure is still sound. What do these leaks or spills do to the concrete below them?
Today, wood trusses are the most common way to frame the roof on a wood-framed building. They offer a high weight-to-strength ratio, long spans, good speed of installation, and a multitude of possibilities for the shape of the roof and the ceiling underneath. Wood trusses can be engineered to span over 25 m (80 ft), and buildings that require large clear spans, such as farm buildings, can also be accommodated.
Whether they are linked to a paper press, a corroded tank or the rupture of seals causing a leak, industrial claims may differ in complexity but they are all potentially costly and dangerous! To understand them, having a diverse team of knowledgeable and experienced investigators conduct the analysis can offer a significant advantage.

These batteries are gaining popularity and are found more and more often in everyday life: laptops, cell phones, power tools, bicycles and vehicles. However, they are not without flaws. In the past year alone, various manufacturers have recalled hundreds of thousands of hybrid cars. So what risk factors come into play?
