Transcript of AUTOMATIC SPRINKLER SYSTEMS NEW LPC RULES JANUARY 2016 THE LOSS PREVENTION COUNCIL (LPC) RULES FOR...

  • IN JANUARY 2016 THE LOSS PREVENTION COUNCIL (LPC) RULES FOR AUTOMATIC SPRINKLER SYSTEMS INCORPORATING BS EN 12845 WERE REVISED.HOW DOES THIS AFFECT A DEVELOPER, OR END USER?

    There have been numerous changes to the LPC rules which not only affect the sprinkler system itself but also how the other building services integrate with it.

    The LPC rules in general apply to commercial projects, however with many schemes in recent years combining mixed use, many buildings have commercial elements covered by the LPC rules. These changes affect projects already in design where the sprinkler contract has not yet been let.

    The new rules apply to all sprinkler contracts let after March 2016.

    The LPC rules are authored by the Fire Protection Association (FPA), an insurance led association, and therefore deviation from the LPC requirements may invalidate or risk insurance cover provided where the presence of a sprinkler system is an insurance requirement.

    These changes affect projects already in design where the sprinkler contract has not yet been let.

  • SOME IMPORTANT CHANGES TO LPC TECHNICAL BULLETINS

    TB203 Sprinkler systems must be annually inspected by a third party to assess compliance with the standard, maintenance, operation and adequacy for the risk involved. These inspections shall be carried out by an independent third party. (i.e. not the system owner, building occupier, system installer or service and maintenance contractor).This requirement is a new addition to the TB.

    TB206 Passive fire protection of sprinklered buildings.Previously there were permitted exceptions to sprinkler protection in some areas with a perceived low fire load, including staircases, enclosed toilets and washrooms. Where sprinklers were omitted, passive fire protection or compartmentation was required to mitigate the risk. This was in the form of 120 min compartmentation. Although permitted exceptions still exist in the standard, they are no longer permitted in buildings over 30 m high. Therefore for a sprinkler system to fully comply with the LPC rules and an LPS 1048 certificate provided for the completed system, all areas must be provided with sprinkler protection, including toilet blocks.

    This does not include necessary exceptions which cover areas where the presence of water may present a hazard. i.e. electrical switch rooms etc. With these areas a suitable alternative suppression system should be considered. It is normal practice to provide sprinklers within electrical rooms and areas where HV is not present.

    Many other changes have been made to the standard which affects the design of other building services systems, e.g. backup power generation provided for wet fire systems.
