The ongoing frigid temperatures serve as a reminder of the many investigations by Warren engineers involving fire sprinkler systems that have failed when some part of the system was exposed to the sub-freezing conditions. Interestingly, failures do not necessarily occur within the area of greatest freeze exposure, as the failure mechanism is the extreme pressure that results from the growth of an ice plug inside the exposed pipe in which the high pressure will rupture the weakest component which may even be located in a heated area of the sprinkler system.

PVC pipe is a durable material used in many construction and renovation applications. Despite its widespread use, problems can arise when manufacturer installation guidelines are not followed. This is especially true in applications that involve gluing joints or, using the more technical term, solvent welding. Read More
The cause of an explosion can result from a chain of events in some cases. In many residential explosions and resulting fires, the facts can point to a number of potential causes. Certified fire and explosion investigators, like Warren engineers and technicians, have the experience and training to uncover and evaluate scenarios with high degrees of certainty. In some cases, like one residential explosion I investigated, the chain of events can start days before the loss.
The safety hierarchy is a well-established principle among safety professionals. It’s a reliable and widely accepted method to minimize or eliminate exposure to hazards in products and workplaces.
