Recently, a medical glass factory gas tank due to the use of a long time, roof collapse cracks leak, a direct impact on production, the need for maintenance replacement, the implementation of fire safety measures, the overhaul carried out safely and smoothly. The gas tank for the floating roof gas cabinet, 4.3 meters high, 7 meters in diameter, volume of about 150 cubic meters, the main storage of crude gas. The production of gas is made of heavy oil catalytic cracking. During the gas production there are flammable naphthalene and tar. The melting point of naphthalene is 80.2 ℃, the ignition point is 80 ℃ and the lower limit of explosion is 0.9
