In May 2023, a man in Nantaihu New District, Huzhou City, Zhejiang Province, accidentally caused a fire with fire while carrying out waterproof construction on the roof of a residential building, and was administratively detained by the public security organs for 10 days. After investigation, the cause of the fire was that the construction worker Xiao used a flamethrower to heat the SBS material, pasted the high-temperature SBS material on the roof, and did not carefully check the potential safety hazards on the site after the construction was completed, resulting in the high-temperature SBS material igniting the surrounding combustibles and causing a fire. The public security organs imposed a penalty of 10 days of administrative detention on him in accordance with the law.

Waterproof operation is divided into four types of construction methods: hot melt method, cold adhesive method, self-adhesive method and wet paving method according to whether the heating method is used during construction, among which the hot melt method is used to heat SBS modified asphalt waterproofing membrane, which is the most widely used in our city, and the use of open flame in the heating process causes a higher risk of fire.
