In this paper, a number of experiments have been conducted on heating cables, the most effective way to save on greenhouse heating cost, to analyze the risk of fire, and to propose fire prevention measures. A field survey of heating cable manufacturing companies was conducted to understand the production process and the heating mechanism. it has studied the fire vulnerability through structural analysis using stereomicroscope and x-ray machine, and through experiments in various environmental conditions. It observed the possibility of overheating due to some product defects, and the possibility of fire caused by deterioration through experiments with extreme environmental conditions, such as using excessive heat shields. In addition, it concluded that the possibility of inadvertent ignition by the contractor and the users was sufficiently high due to the fire experiments that reproduced unstable elements detected at the fire scene, such as cutting, twisting, pressing, over-winding the heating cables.
