Abstract

See full text

An extinguishing lance for electrical devices that are burning, has a holding portion having a handle part for operation, an extinguishing-agent feed having a coupling device for connecting a pressure hose for extinguishing agent, and a tubular extinguishing portion, from the free end of which extinguishing agent is introduced, under pressure, into the object that is burning. The extinguishing portion tapers to a point at the free end and has a constricted, hollow flow cross-section for extinguishing agent conducted under pressure. The extinguishing portion and its tapered, additionally hardened end are produced from stainless steel. The extinguishing portion has, at least in the region of the holding portion, a voltage-insulating coating, which is electrically insulating for electric voltages U≥500 V. Thus, the minimum legal requirements for protection against thermal hazards, against mechanical overloads, and against electrical hazards are reliably met.
