According to the State Fire Service of the Russian Federation, every third fire in Russia is somehow associated with faulty wiring. Comparable figures only in fires due to human negligence. The main cause of malfunctions is the general dilapidation of the housing stock. The share of fires due to faulty wiring in new buildings is relatively small, nevertheless, each of these cases is carefully analyzed. As a rule, a fire occurs due to egregious violations during the construction process. Recently they began to attract more and more often in court.
It should be noted that modern materials are quite difficult to “spoil” in such a way as to cause a fire. As a rule, one must either be a completely incompetent employee, or use completely low -quality building materials. Cable-wire products, such as ASBB cable, has a practically “unexpected” reserve of reliability. As a rule, using new materials, even confusing something is quite difficult, literally everything is standardized, up to fasteners.
As for the old houses, often their service life has expired 20 years ago, while we are talking about the life of the houses themselves, and not just the wiring. But since most of the population of Russia simply cannot afford the purchase of new housing, their operation continues. Of course, periodically in houses with aluminum wire instead of a fuse on the wiring, fires occur, competent specialists conduct an investigation, establish the cause, but they can not do anything.
