House fires do not give warnings. They come from a fault, an overheated component, something that can catch alight when no one is watching. The fire can move quickly and decisively. Most people who have never experienced a house fire will be shocked at how quickly things move. The critical minutes of a house fire are usually in the first few minutes before anyone can fully understand what is happening. Your home can either work for or against you during that time. Without proper protection, downlights will work against you.
When there is a fire in a house, the ceiling acts as a fire barrier. It is a barrier between floors that gives a person time to escape the house. The fire barrier must withstand the heat for a certain time, depending on the regulations. Fire barriers will need a continuous ceiling to work properly. If a downlight is installed in a ceiling without a fire-rated cover, the hole created by the fitting is a pathway for heat, smoke, and flames to spread through the hole in the ceiling.
The fire will move up and towards oxygen. Therefore, a ceiling with holes is a direct path for fire to spread through. Fire-rated covers can ensure a ceiling will be intact for at least 30 to 60 minutes. This time gives a smoke alarm time to wake people and also gives people time to escape the house.

This is not just a theory to sell you a product. This is the reason that a fire-rated cover is required. It can be a lifesaver for those living in the house. Not following regulations for downlight protection can be a grave decision that nobody wants to make.
