Internal Fire Doors

Internal fire doors vary in size, type, fire rating and aesthetics; it can be challenging to choose the correct type. For example, a thicker, heavier fire door does not mean that it will necessarily provide better protection.

Accredited Fire Door Installer

You must choose an accredited and trustworthy fire door manufacturer to ensure that the fire door conforms to the relevant UK fire door regulations.

Before purchasing fire-resistant doors, you must consider several other factors, such as security requirements, fire-resistant glazing, ventilation requirements, and high traffic areas.

The Responsible Person

Under current regulations, organisations must appoint a responsible person to manage the safe installation, maintenance, and inspection of fire doors.

Competent Person

A competent person should check internal doors regularly to ensure they function correctly. The checks should be considered the same way as testing a smoke alarm or a fire extinguisher. Any slight alteration to the fire-resistant door or its surroundings and frame can impact the performance of fire-rated doors.

Regular Inspections

The responsible person should carry out the inspections at the intervals stated in the fire risk assessment. The fire safety manual/logbook should include a record of the maintenance tests, and any defects remedied should be logged in the fire safety manual/logbook.

The following is a sample of the door checks that ClearView fire door specialists undertake to assess the serviceability and integrity of fireproof doors. The checks should be carried out at least 6 monthly to comply with UK statutory regulations for fire doors.

• Check that the frame to door leaf gap does not exceed 4 mm (or in line with the manufacturer’s datasheet) and that the door easily closes.
• Check that hinges and push bars are correctly lubricated in accordance with the manufacturer’s recommendations (where applicable).
• Check that the quantity of hinges is the same quantity to which the door has passed its fire certification (normally at least three).
• Ensure the door to floor covering gap is consistently 10 mm or less when the door is closed. For fire doors required to limit the spread of cold smoke, the threshold gap should either be less than 3 mm, or it should have a threshold smoke seal fitted.
• Visually inspect intumescent (heat-activated) seals, smoke seals (including brush or fin type) and acoustic seals for signs of wear or deformation and replace, as necessary.
• Check that the intumescent seal is continuous and attached to the glass and bead.
• Check for missing seals and replace, as necessary. Check that smoke seals have not been painted or varnished (intumescent strips may be overpainted per the manufacturer’s recommendations)
• Check that the seals are well attached inside the groove in the frame or door leaf. Ensure that any smoke seals and acoustic seals have not been fitted in short sections, for example, if localised damage has been repaired by splicing in a short piece of the seal. NOTE: This may be acceptable in psychiatric units as an anti-ligature safeguard.
• If the glass has been replaced, check that it is fire-rated glass and the same as the original or as specified in the door manufacturer’s datasheet.
• If glazing panels are below 1500 mm from the bottom of the door, check that the glass is also safety glass.
• Ensure door leaves are not structurally damaged or excessively bowed or deformed. Ensure hanging devices, securing devices, self-closing devices, and automatic release mechanisms are operating correctly.
• Inspect door coordinates on double doors. Ensure the coordinates are securely attached and adjusted properly to allow the first leaf (inactive leaf) to close before the second leaf (active leaf). Check this by completely opening both doors and simultaneously releasing them.
• Test the operation of the panic hardware where fitted.
• Check for correct labelling or confirm fire door certification
• Ensure the correct sign is associated with the door and secured on both sides of the door unless it is “Fire door keep locked”, in which case it would be on one side
• Check any associated alarms to mimic the panel for operation if fitted.
