The main culprit for fire caused by fluorescent lamps is the ballast. The reason why a ballast can cause a fire is that the temperature of the ballast itself is increased, and the surrounding combustibles are ignited for a long period of time. In order to prevent fire caused by fluorescent lamps, the following points should be noted when installing and using fluorescent lamps:
(1) To ensure good quality and never to buy ballasts with poor quality;
(2) The ballast shall not be installed on flammable building components, such as wooden beams, columns and ceilings made of plywood;
(3) The power and voltage of the ballast must be the same as the lamp power and voltage, and be wired in accordance with the specified method;
(4) Do not use it continuously for a long time. In particular, after the damage of the fluorescent lamp, it should be promptly replaced to prevent accidental opening, so that the ballast is overheated for a long time and it causes fire.
