Due to be issued very soon. Update to LPC Rules for Automatic Sprinkler Installations 2015 is coming soon DecemIn a letter to industry last week, the Fire Protection Association announced a new change within the LPC Rules for Automatic Sprinkler Installations 2015 incorporating BS EN 12845, clause 12.4.2.

The thermal elements respond to localised heating, which expand the liquid, breaking the bulb to release the plug and allow water to flow.These thermal elements do not respond to smoke and they operate individually when they achieve a set temperature. The thermal element holds in place a plug. Detection is handled mechanically by heat-sensitive thermal elements typically constructed from a glass bulb containing a liquid.

However a recent study, carried out by the Chief Fire Officers Association and based on real fire events, demonstrated the reliability of operation at 94% with an effectiveness in operation of 99%, placing the probability of success at the top end of the range noted by PD 7974-7:2003.This CPD will consider how the inclusion of automatic sprinkler systems impacts on the design of a range of building types.The cost and design complexity of a sprinkler system generally increases with fire risk. Sprinklers have an 80-95% probability of being successful, according to Published Document PD 7974-7: 2003 вЂњApplication of fire safety engineering principles to the design of buildings вЂ” Part 7: Probabilistic risk assessmentвЂќ, which supports British StandardBS 7974. Discharge in the presence of fire is extremely reliable and discharge in the absence of fire is rare. Automatic sprinklers will typically only operate in areas where fire is present, so that adjacent areas remain unaffected.

Systems can be designed to conceal pipes, and the availability of decorative sprinkler heads allows them to be matched with the interior of the space.Design density, often expressed in mm/min, is the water discharge required in litres over 1m 2 per minute. For example, offices, which are considered lower risk, have a lower water demand than high-bay warehousing. It is expressed through the head spacing dimensions, the area of maximum operation (number of heads in operation), design density (water discharge) and the water supply period.The cost and design complexity of a sprinkler system generally increases with fire risk. The sprinkler design then specifies the sprinkler system needed to meet that fire hazard. The specifications of the design depend primarily on the hazard classification of the occupancy of the building, which defines the scale of the fire hazard.

BS 9251:2014 вЂ“ Fire sprinkler systems for domestic and residential occupancies BS EN 12845:2015 вЂ“ Fixed firefighting systems: Automatic sprinkler systems This in turn defines the minimum water volume requirement (capacity from the public main or water tank size).Applicable standards to automatic sprinkler systems are: Water supplies are required to supply the required flow (depending on the system design) for a minimum duration that varies from 30 to 90 minutes depending on the hazard classification. This addresses the nature of the fire risk and recognises that some fires will grow faster than others. This can be summarised as the flow of water required to contain the fire, which increases with the occupancy risk category.

For example, their installation can enable larger compartment sizes, reduced structural fire-protection requirements, increased travel distances and stair configuration, reduction in fire-fighting shafts and reduced circulation areas, leading to an increased useable area.One Harbour Gate in Hong Kong вЂ“ The installation of an automatic sprinkler system allowed greater freedom to create a landmark facade STATUTORY REQUIREMENTSIn England and Wales, fire-safety requirements associated with building works are given in Part B of Schedule 1 to the Building Regulations. This requires an assessment of a variety of factors including building size, use and fire safety risk.Automatic sprinklers can permit freedom of design, in turn leading to savings in initial capital costs, lifecycle costs and on the construction programme. NFPA 13: Standard for the Installation of Sprinkler SystemsBecause the installation of an automatic sprinkler system can further reduce the risk to life and the degree of damage caused in a fire event, it can enable the reduction of other fire protection measures such as fire-resistant construction, compartmentation, fire resistance of external facades and glazed elements and fire-fighting access and facilities.

This is supported by series of Published Documents (PD 7974 1вЂ“8) that contain guidance on undertaking detailed analysis.Table 1: Compartment size limits given in Approved Document B Building use / typeMultistorey assembly, recreational or commercial buildingMultistorey industrial building, with occupied floors в‰¤18mMultistorey industrial building, with occupied floors >18mSingle-storey storage building, with a building height в‰¤18mSingle-storey storage building, with a building height >18mMultistorey storage building, with occupied floors в‰¤18mMultistorey storage building, with occupied floors >18mIMPACT OF SPRINKLER SYSTEMS ON BUILDING DESIGN: BUILDING REGULATIONSApproved Document B offers guidance to provide certain premises with sprinklers. BS 7974:2001, concerning the application of fire-safety engineering principles to the design of buildings, provides a framework for the application of scientific and engineering principles to achieve adequate protection of people, property and the environment. BS 9999:2017 Code of practice for fire safety in the design, management and use of buildings provides a more transparent and flexible approach to fire-safety design This is intended for common or simple buildings, and may not be suitable for more complex designs.

HotelsВ and student accommodation are a notable exception вЂ“ they do not require automaticВ sprinklers regardless of height.Approved Document B also contains guidance on areas such as means of escape and layout for specific building types. In fact, Approved Document B recommends automatic sprinklers for mostВ building types with a storey above 30m. It applies to residential buildings and offices with a storey over 30 metres and to buildings such as retail stores with a floor area greater than 2,000m 2 and warehouses over 20,000m 2.
