Water Mist Fire Protection A Smarter, Safer Solution for Healthcare & Acute Hospitals

BlueLight Fire Engineering brings proven expertise in the design and delivery of water mist fire suppression systems across a wide range of healthcare environments.

Recognised for their performance and compliance, water mist systems are now increasingly viewed as a credible alternative to traditional sprinklers—an approach reinforced by an NHS technical bulletin issued late 2025, confirming their suitability for complex clinical settings.

Water mist systems provide rapid, effective fire suppression by addressing the three elements of fire; heat, fuel, and oxygen while using far less water than traditional sprinklers. This reduces fire growth and secondary damage, making them particularly well suited to healthcare and acute hospital environments where patient safety, continuity of care, and protection of sensitive equipment are critical.

  1. Rapid cooling - Fine water mist droplets absorb heat efficiently, quickly reducing temperatures and slowing fire growth while protecting people, structures, and equipment.
  2. Fuel wetting - Lightly coats combustible materials to suppress flames and limit fire spread, using far less water than conventional systems and minimising water damage.
  3. Oxygen displacement - Evaporation into steam locally reduces oxygen at the fire source, inhibiting combustion without creating unsafe conditions for occupants.

Why Water Mist is Well Suited to Hospitals

Healthcare buildings present unique fire safety challenges. Hospitals operate 24/7, accommodate patients who may be unable to self-evacuate, and house life-critical clinical services and highly sensitive equipment. Water mist systems offer several key advantages:

  • Enhanced patient and staff safety – Rapid suppression helps control heat and smoke early, supporting progressive horizontal evacuation strategies.
  • Reduced water damage – Lower water volumes help protect medical equipment, electrical systems, and clinical infrastructure.
  • Improved business continuity – Faster fire control and reduced secondary damage can minimise disruption and support quicker recovery.
  • Protection of critical spaces – Effective in areas containing sensitive or high-risk equipment, including plant rooms, electrical rooms, data facilities, and specialist clinical areas.
  • Suitable for occupied environments – Designed to suppress fire efficiently without creating hazardous conditions for occupants.
  • Sustainable and efficient – Reduced water consumption supports environmental objectives and long-term resilience strategies.

What our clients say

Lance provided specialist advice to the NWAFT Backlog Maintenance project teams over past 4 years, including advice on design, fire alarm systems and commissioning of the fire engineered solutions within the new multi-million-pound Theatre building at our Hinchingbrooke Hospital site. This building houses 7 new theatres, with state-of-the art infrastructure.

Lance also assisted, advised and provided specialist fire support for the Stamford Hospital new Day Treatment Unit, which again, is a brand-new state-of-the-art treatment centre, providing local care for local patients. Lance assisted with initial design, pre & post build inspections and fire safety commissioning prior to occupation. During the build, Lance was able to undertake inspections and provide critical fire safety advice to the construction company.

At the Peterborough hospital campus, Lance was the trust chosen and appointed fire engineer for the conversion of the fourth floor to two 35 bed in-patient wards. Lance provided pre-design advice and commissioned the two areas post build. This was a unique project in that escape from ward A17 as known, exceeded advised travel distances. Lance’s commitment, knowledge and dedication assisted the trust by finding an acceptable mitigation deemed suitable by the local fire authority.

To summarise, I fully recommend Lance to any interested party as a competent, qualified, moreover, experienced authorising fire engineer.

My predecessor and senior managers with the Fire Authority spoke highly of the expertise and professionalism shown by Lance, I would strongly endorse their views.

During my time in this role a range of complex issues have been dealt with on the QA site, involving diverse issues that include engineered solutions, specification of the sprinkler installation, atrium fire loading, compartmentation, plant room design, site management, fire investigation, risk assessment, false alarm reduction.

I have found Lance to be unique in that in addition to having a very detailed understanding of legislation standards and codes he has the rarely found ability to apply and communicate relevant requirements.

He is highly respected in this office, I have on many occasions highlighted the results of work to other organisations as outstanding good practice, it is my hope that he will remain in his role for an extended period.

Lance has completed outstanding work for our trust over the past four years as Authorising Fire Engineer.

Lance has always provided top level fire safety expertise and support where required, always making himself available in and out of hours at the end of the phone or via Teams. As a former Royal Air Force Fire-fighter, frontline NHS fire Safety manager, fire alarm engineer, his knowledge base has been gained from these front-line positions.

As a respected and qualified Authorising Fire Engineer, Lance demonstrates a calm but firm approach when it comes to fire safety. He has demonstrated loyalty and commitment to our trust in his role, and this made him a very respected contractor by trust senior management.

Bluelight Fire Engineering have consistently delivered an excellent standard of technical expertise and professionalism. Their engineers bring a depth of knowledge that gives confidence, particularly when navigating complex healthcare environments. At the same time, they remain approachable, supportive, and invested in helping us make informed, safe decisions. 

Their reports and recommendations are clear, their communication is always reliable, their commitment to safety and service is evident in every interaction, and I would not hesitate to recommend Bluelight Fire Engineering to any organisation seeking robust, dependable fire engineering support.
