Putting out halon

摘要

At Kozloduy 5 and 6 the existing halon extinguishing systems are designed as object protection systerns for electrical cabinet rows. Each of these rows is protected by a small dedicated halon gas cylinder, directly installed on the sheet metal housing in front of each cabinet row. In compliance with international restrictions on the production of certain halon fire extinguishing agents under the Montreal Protocol, signed 16 September 1987, replacement of this agent at Kozloduy 5 and 6 was required for environmental protection reasons.
