RISK INSIGHT, STRATEGY AND CONTROL AUTHORITY Reducing insurable risk through research, advice and best practice

Background • The need for sprinklers arose as the leading insurance companies developed • They improve economic efficiency: specifically they reduce consequences and losses from fire • Originally motivated by need to protect property (high value/large scale stock and processes) • As we don’t know when or where a fire will start, sprinkler installations must sit idle for long periods of time before reliably performing their function: an extraordinary design challenge RISK INSIGHT, STRATEGY AND CONTROL AUTHORITY Reducing insurable risk through research, advice and best practice

Development of UK Sprinkler Rules • The FOC (Fire Officers Committee) published the first set of installation rules in London in 1888 • LPC (Loss Prevention Council) later took over this function from FOC • These rules were the basis of most global standards and have evolved ever since their inception, e.g.

• FOC …..27th, 28th, 29th editions • BS5306 Part 2 1979 & 1990 + LPC Rules editions • BS EN 12845: 2003, 2004, 2009 & 2015 + LPC Rules editions

RISK INSIGHT, STRATEGY AND CONTROL AUTHORITY Reducing insurable risk through research, advice and best practice

Continuous Improvement • This model of standard development is really just a very mature example of continuous improvement • Combined with the inherent simplicity of the firefighting approach (automatically, uniformly sprinkling water onto a fire) has proven to be a winning formula • So much so that people now constantly seek to emulate technology in other forms

RISK INSIGHT, STRATEGY AND CONTROL AUTHORITY Reducing insurable risk through research, advice and best practice

Some bodies involved today • CEN (European Committee for Standardization): • Produces ‘EN 12845’ by committee • BSI (British Standards Institution) • Adopts ‘BS EN 12845’ (adds ‘National Foreword’ and now ‘National Annex’) • FPA (Fire Protection Association) & RISC Authority: publish the LPC Rules (with input from insurers, the sprinkler industry and other stakeholders) • Based upon BS EN 12845 + additional requirements (loss prevention and best practice)

RISK INSIGHT, STRATEGY AND CONTROL AUTHORITY Reducing insurable risk through research, advice and best practice

Acronyms • LPC Rules – Understandably, often confused with the LPCB • LPC – Loss Prevention Council – LPC Rules are published by the FPA in association with and funded through RISCAuthority • LPCB – Loss Prevention Certification Board (Third party accreditation and certification body and part of BRE Global)

RISK INSIGHT, STRATEGY AND CONTROL AUTHORITY Reducing insurable risk through research, advice and best practice

Improvement • FPA & RISC Authority produce the LPC Rules by improving and supplementing the requirements of BS EN 12845 • With significant technical contributions from the Sprinkler industry and Insurers • Based on: research and case study experience of realworld fire events (and escape of water or other failure events and component problems) – lessons learned / continuous improvement

RISK INSIGHT, STRATEGY AND CONTROL AUTHORITY Reducing insurable risk through research, advice and best practice

Improvement / research projects: • Protection of plastics using foam (updating Annex ‘G’) • Protection of flammable liquids (updating TB214) • Review of TB234 to consider new storage challenges (such as ASRS) • Early engagement with the fire brigade in relation to potential greater fire storage challenges

The design and hydraulic efficiency of the system is based on the flow of water passing through all pipes in the grid or, in sections of distribution mains in looped pipework configurations trapped air can significantly restrict or prevent this flow of water.

‘C’ value table has been updated to reflect the use of Polyethylene high density (H.D.P.E.) pipework – for use in hydraulic calculations RISK INSIGHT, STRATEGY AND CONTROL AUTHORITY Reducing insurable risk through research, advice and best practice

Significant changes: Technical Bulletin TB234:Protection of High Hazard Storage (HHS) Configurations •Feedback from users of the LPC Rules implies there could be misinterpretation of the increase in design density option to combat excessive roof clearance, as defined in TB234.4.2, Figures TB234.F2 & F3 and in the 'C & R on TB234.4.2’.

•The existing wording in the C & R required the use of this increase in design density option to be declared as a 'minor non-compliance' upon any certificate of conformity issued for the system, which may not be the case, therefore an amendment to the wording of the C & R has been updated in this context.
