What is a smoke ventilation system?Smoke control and ventilation systems can be either natural or mechanical systems that vent smoke out of a building to enable low level escape routes to be kept clear of smoke, aiding visibility in the case of an emergency. This makes it easier for occupants to escape from a fire, and also prevents further damage to a building. Different premises will have different needs for smoke control and ventilation systems depending on their size, style and the number of occupants within them. According to statistics published by the UK Government, the most common cause of death in the instance of a fire is a person being overcome by gas or smoke, leading to loss of consciousness and eventual loss of life. An effective smoke control and ventilation system is therefore crucial in order to keep smoke away from commonly used areas in a building such as corridors, safety routes, staircases and lobbies. If a fire breaks out, an effective smoke detector should activate on every floor of a building, ensuring that occupants can easily and safely escape while the fire is in a state of infancy.
Natural versus mechanical ventilation systemsThere are two main types of smoke control and ventilation systems – natural and mechanical. Natural ventilation systems use the natural movement of hot gasses to vent smoke through a ventilator. Natural systems use windows, vents and automatic opening vents (AOVs), and are used as part of UK Building Regulations. Natural systems can also offer everyday air ventilation. Mechanical systems require extraction and removal of smoke by forcing it through fans.
The need for replacement airIt is essential to have a supply of replacement air that takes the place of gasses and smoke that is extracted from a building. If replacement air doesn’t come in to a building, it will become depressurised. This air supply can be sourced from natural ventilators that are in a remote position away from a fire, automatic doors or from inlet ventilators that are positioned near the floor. Why install a smoke ventilation system? A smoke control and ventilation system greatly reduces the chances of building occupants choking or being overwhelmed by smoke. It reduces the risk of smoke inhalation around escape routes such as corridors and staircases, and makes it easier for emergency services to access a building. A well-implemented smoke control and ventilation system can reduce the risk of a fire developing and limit smoke damage to a building (as well as the equipment inside it such as computers and other technical equipment, or even personal possessions). How do smoke detectors work? A smoke control and ventilation system is activated by smoke detectors. Once activated, the system should force a natural flow of air into a building while smoke is removed.

Having the correct lighting installed in a premise is very important to the health and safety of those using it particularly if it is a workplace. Correct LED emergency light installation makes it quicker and easier to identify hazards while making an environment easier and more comfortable for people to work in because of optimum light levels. Poor lighting can have a detrimental effect on employees’ and visitors’ health in an organisation’s premises, including:
- Migraine and headaches
- Sick Building Syndrome
- Epileptic fits/seizures
Having the correct LED emergency lighting is essential for any business and or premises owner, especially in cases where a sudden loss of light would prevent safe escape from a building in an emergency. At RES Fire Protection Engineers, we offer the following services for LED Emergency light solutions:
- Regular inspection and testing
- Fault identification
LED Emergency lighting and the law
LED emergency light solutions are a UK legal requirement in all non-domestic and certain types of residential premises, as they ensure that a building is compliant with relevant British Standards and the law (Regulatory Reform Fire Safety Order 2006). This is something we can check for you at RES. We can also advise on and provide emergency LED lighting for your business, so that you can have a bespoke solution based on your business requirements. Regulations regarding LED emergency lighting are very specific, and you need to adhere to the following areas in order for premises to be compliant:
- Illuminate escape routes adequately for ease of visibility
- To provide sufficient illumination so that all users of a building can effectively access escape routes
- To use lighting in an effective way so that all fire alarm call points, fire extinguishers and other safety equipment can be easily located
- To provide sufficient lighting so that proper shut down procedures can be carried out in high risk locations
LED emergency lighting needs to be activated for the entire period that a danger exists, or until normal lighting is restored for work to be undertaken as normal. If a normal lighting system fails in the event of a fire, a back-up power source is required for LED emergency lighting to fully function as necessary. This can be achieved by way of battery packs to each LED emergency light or by way of a centralised battery system To prevent glare, it is important to LED emergency lights should be mounted at least 2m from the floor so that effective light can illuminate all areas around a building and various escape routes.
Types of emergency lighting system
Maintained – LED emergency lights that operate as a normal light fitting and can be controlled with all the other lights in the area, however when the power fails the maintained emergency fitting will continue to operate but at a lower light level.
Non Maintained – Is normally switched off, with its batteries being continuously charged and a green LED showing fully charged. When the power fails then the fitting switches on using its battery supply. Non-maintained fittings are not part of the general lighting but are fittings such as emergency exit signs
