Firefighters have warned that glass objects left in direct sunlight can start fires after sunlight refracted through a garden table and ignited a blaze. The incident highlights a lesser-known summer fire risk, particularly during hot, dry conditions when nearby materials can catch fire more easily.

The warning applies to glass furniture and other transparent objects that can concentrate sunlight onto combustible surfaces. Fire crews are urging people to consider where such items are placed outdoors and to keep them away from dry grass, furniture, fencing and other flammable materials.
