David Bohn of Redding, CT is the vice president in charge of sales for Preferred Utilities Manufacturing Corporation. David Bohn is responsible for managing sales and service personnel for the company, which is known for manufacturing industrial boilers. Boilers are responsible for providing hot water and central heating in nearly every home and business in the country. Boilers today are designed to function as safely and efficiently as possible, but accidents do sometimes occur. Among the most common boiler accidents are what are known as “dry fire accidents,” or “boiler meltdowns.” Dry fire accidents occur when a boiler continues to operate without an adequate water supply. In a best-case scenario, these accidents can cause irreparable damage to the boiler within minutes – in the very worst cases, the boiler can be ripped apart from the boiler tube sheet and propelled with great velocity, causing damage to property and even injuries. At least one dry fire accident occurs in America almost every year, but fortunately, these accidents are very preventable. The cause of a dry fire accident is a simultaneous failure in several redundant safety controls on a boiler – the safety controls for temperature, pressure, gas supply, and water supply. One cause of these occurrences can be avoided by making sure that whenever a combination valve is replaced with a single pressure reducing valve, a separate pressure relief valve is installed as well – failure to do so can prevent a boiler from relieving excess pressure. A dry fire accident can also be prevented when the owner of a boiler is aware of the signs of overheating – some telltale signs include the smell of smoke or something burning, excessive heat in basement or living areas, and the emergency switch on the boiler set in the “off” position. If a boiler is cherry red in color, has paint peeling off, or is leaking water or steam, the owner should take immediate action before a dry fire accident can occur. Touching parts of the boiler can also trigger an accident by disturbing the wiring or turning a valve, and should be avoided.
