Fire Suppression

Fire suppression can often become a necessity in order to comply with your legal requirements for Building Control approval, to meet your insurers requirements or to offset otherwise onerous fire precautions. Often an overview of your premises fire precautions strategy can reveal the installation of total or partial fire suppression system could reduce building and insurance costs, or provide you with other operational benefits. Fire suppression systems work against the development of fire in a variety of ways so it is therefore essential that the designer is fully aware of all fire safety engineering options available, such that the optimum solution can be adopted.

LWF are able to undertake on your behalf:

  • A detailed hazard identification analysis of your premises for current and future occupation.
  • Prepare on your behalf, feasibility assessments identifying options for fire suppression and risk reduction against potential costs.
  • Assist you in the preparation of a cost benefit analysis.
  • Advise you on suppression options relevant to the specific use of your premises and the implications of discharge on the building and occupation.
  • Define optimum sprinkler configuration suitable to the hazard and risk within your premises.
  • Undertake detailed sprinkler designs to meet any hazards and interface as appropriate with any existing fire engineering designs within your property.
  • Identify and define on your behalf, all possible fire suppression options including; water mist, gaseous, foam, or dry powder-extinguishing agents.
  • Provide you with independent advice on suppression systems manufacture, performance, suitability and appropriateness for individual circumstances.
  • Prepare detailed water supply, infrastructure and distribution pipe-work layouts on CAD.
  • Prepare detailed performance and materials specifications.
  • Prepare tender packages and provide full project management services.
  • Represent and negotiate with all statutory approvals authorities on your behalf at the design and post construction stages.
  • Advice on systems servicing requirements and service contracts.
  • Provide staff training in systems operation.
  • After-care service, including for changing needs and hazards, and advice on adaptation and extension of the system.

FIRE SAFETY BLOGS

  • Fire Safety for Healthcare Premises - Vertical Escape - Part 23

    In LWF’s blog series for healthcare professionals, we look to give information on best practice in fire safety for hospitals and other healthcare premises. In part 22 of this series, we looked at the issue of vertical escape in relation to stairways and ascertained that in effect, all stairways in a hospital must be considered escape stairways as they would be used for escape in case of fire. In part 23, we will continue looking...

  • Facilities Management & Fire Safety - Inspection, Testing and Maintenance - Part 1

    In LWF’s blog series for Facilities Managers or those with an interest in or responsibility for fire safety, we aim to give an overview of best practice and methods of applying or maintaining fire prevention provision. In part 1, the importance of inspection, testing and maintenance of fire protection measures is discussed.Once fire protection measures are installed in a building, it would be comforting to think that they were simply waiting in case they...

  • Fire Engineering Design and Risk Assessment - Foam Proportioning - Part 4

    In LWF’s fire engineering blog series for Architects and others in the building design business, we have been looking at fire suppression systems and in particular, foam systems. In part 3, it was ascertained that foam proportioning is the means by which foam concentrate is mixed with water at the necessary ratio. An overview of inductors (also known as line proportioners) was given. In...

  • Fire Safety for Healthcare Premises - Vertical Escape - Part 22

    In LWF’s blog series for healthcare professionals, the aim is to give information on best practice of fire safety in hospitals and other healthcare premises. In part 21 of this series, LWF looked at the necessary considerations of hospital streets and escape route widths. In part 22, we will look at vertical escape using stairways.While it is possible for organisations to denote certain staircases as escape stairs (and therefore, certain staircases are not classed...

  • Fire Engineering Design and Risk Assessment - Foam Systems - Part 3

    In LWF’s Fire Engineering blog series for Architects and others in the building design business, we have been looking at fire suppression systems and, in particular, foam concentrate systems. In part 2, we began an overview of the different types of foam concentrate and part 3 will continue from that point before discussing foam proportioning.Synthetic, or high expansion foam is produced from detergents and, as a result, can produce great quantities of ‘bubbles’ making...
