Garage Door Safety Checklist
1. Is the door between the garage and house at least 44 mm thick?
■ Yes ■ No ■ Not Sure
Explanation: A door at least 44 mm thick is typically fire-rated (per the FD30 standard in many regions). This thickness helps provide at least 30 minutes of fire resistance, slowing the spread of fire and smoke from the garage to the house.
2. Does the door have a self-closing device that automatically shuts it?
■ Yes ■ No ■ Not Sure
Explanation: A self-closing device ensures the door automatically closes after being opened. This is important because a fire door only works effectively when fully closed, helping to prevent fire and smoke from spreading.
3. Are there fire or smoke seals (intumescent strips) around the door or frame? ■ Yes ■ No ■ Not Sure
Explanation: Intumescent strips expand when exposed to heat, sealing gaps around the door. Smoke seals prevent toxic smoke from passing through small gaps, improving overall fire protection.
4. Is the wall between the garage and living space masonry (brick/block) or a properly fire-protected stud wall? ■ Masonry ■ Stud Wall ■ Not Sure
Explanation: Masonry walls (brick or block) naturally provide good fire resistance. A stud wall must be properly fire-rated (e.g., fire-resistant plasterboard and insulation) to achieve similar protection.
5. Are all service penetrations (pipes, cables, ducts) properly sealed with fire-stopping material? ■ Yes ■ No ■ Not Sure
Explanation: Openings around pipes, cables, or ducts can allow fire and smoke to spread quickly. Fire-stopping materials (e.g., fire-rated sealant or collars) maintain the fire resistance of the wall or ceiling.
6. Has the garage been converted into a living space or office? ■ No ■ Yes ■ Partially
Explanation: A converted garage changes fire risk and building regulation requirements. Fire separation standards may differ depending on whether the space is still used as a garage or as habitable accommodation.
7. Is the floor between the garage and the living space stepped down by approximately 100 mm? ■ Yes ■ No ■ Not Sure
Explanation: A 100 mm step down helps prevent flammable liquids (like petrol) from flowing into the house in case of a spill. It also provides an additional barrier against fire spread.
Summary
If the answer is No to questions 1–3 (door not at least 44 mm thick, no self-closing device, and no fire/smoke seals) and Yes to question 6 (garage converted to a living space or office), it is likely that the existing door does not meet modern fire separation standards.
Under current building practices and typical insurance risk expectations, a door between a garage (or former garage) and the main house should generally provide FD30 fire resistance (minimum 30 minutes), be fitted with intumescent/smoke seals, and have a self-closing mechanism.
Without these features, the property may not provide adequate protection against fire and smoke spread, and upgrading to a compliant FD30 fire door assembly would likely be recommended for both fire safety compliance and insurance considerations.
