What is a primary fire risk associated with radiant heaters?

The primary fire risk associated with radiant heaters stems from combustible materials being left too close to the heater. Radiant heaters operate by emitting infrared radiation, which can generate significant heat in their vicinity. When combustible materials, such as papers, fabrics, or wood, are positioned near these heaters, they can easily ignite due to the intense heat radiated, leading to a potential fire hazard.

While issues such as overheating the electrical system, failure to follow installation instructions, and malfunction of safety features can indeed pose risks, the immediate and common risk presented by radiant heaters is the proximity of flammable materials. This makes it essential for users to maintain a safe distance between the heater and any potential combustibles to prevent ignition and ensure safe operation.
