Fire Safety Engineering for Design – Property & Life Safety Protection – Part 260
November 10, 2025 11:13 amLWF’s Fire Safety Engineering blog series is written for Architects, building designers and others in the construction industry to highlight and promote discussion on all topics around fire engineering. In part 259, LWF discussed the maintenance of sprinkler systems. In part 260, we talk about fire suppression for life safety or property protection.
When discussing fire safety, there are two distinct purposes a fire protection or fire suppression system may be put into place to fulfil – life safety and property protection. A life safety system is commissioned with the aim of protecting the people in a building while they are removed to a place of safety – either through self-evacuation or with assistance. A property protection system is implemented in a building where the building itself or the contents are the reason for protection. This can be as straightforward as protecting valuable historic architecture, an art gallery with valuable paintings or the tech/machinery needed for a business to continue to function after a fire.
A sprinkler system designed either for life safety or property protection will undoubtedly be designed along similar lines in most cases, and therefore a sprinkler system designed to protect property will also give some life safety benefits to building occupants, and vice versa.
The spacing of sprinklers, the size of the pipework and general arrangement is likely to be identical. However, sprinkler systems designed for life safety purposes tend to have enhancements designed to improve reliability and ensure water is available at the sprinkler heads when it is required.
Originally, sprinkler systems were intended to protect property in the main, but the fact that they suppress the fire development and in some cases, extinguish a fire before it can grow significantly, mean that the safety of the people within the building and attending firefighters is improved. Fire is less likely to spread to adjacent properties when a sprinkler system is installed.
Some sprinkler systems are installed solely for life safety purposes as a part of a life safety strategy and this approach may have been taken in order to allow concessions with other fire safety and fire protection measures, (travel distances for safe evacuation may be increased, for instance).
In part 261 of LWF’s series on fire engineering we will continue talking about life safety and sprinkler systems. In the meantime, if you have any questions about this blog, or wish to discuss your own project with one of our fire engineers, please contact us.
