The Need For an Efficient Fire System

People safety is of paramount importance in the event of a fire outbreak in commercial spaces and multi-family apartments. Fire regulations in commercial buildings state that fire blankets and extinguishers must be at hand in the event of a fire outbreak. There is also a need to identify and install a proper fire door exit system. A Health & Safety Officer will conduct a fire risk assessment of the building to produce a fire management plan and specify which fire doorsets suit the fire system of the building.

Fire Resistant Doors as Protection Gear

In residential properties, the Regulatory Reform (Fire Safety) Order 2005 specifies fire safety in terms of fire retardant furniture, smoke alarms, electrical systems, and fire doorsets. The main function of fire-resistant doors is to contain the smoke and fire and delay the effects of smoke inhalation. Mikasa manufactures superior performance solid particle doors core with a density that ranges between 600 – 850 kg/m3. The door frames of fire-resistant doorsets are made of LVL or high-density hardwood that is more than 640 kg/m3, depending on the desired fire rating. The frame is matched with the door at the time of manufacturing to produce a flawless finish.

Fitting Fire Doorsets

Fire-resistant doors should be installed in a doorway leading to a staircase above two levels. For instance, a door that leads to a loft conversion will require a fire-rated door, entrances between an internal garage and the main house should be equipped with fire doors to prevent smoke and fire from spreading. While installing a fire door, it’s important to assemble all the parts correctly so that it can safeguard the property effectively. Petty differences in details in fire door sets including glazing apertures, door frames, and intumescent seals will significantly affect its performance. Besides, it is important to keep fire doors closed every time and fit the intumescent door seals to the door head and stiles correctly. When temperatures in the vicinity of a fire rated door exceed 200°C, the intumescent fire door seal swells from the heat and seals the gaps between the frame and the door leaf. This action helps in safeguarding the building’s occupants in the event of a fire.
