Causes and Countermeasures of welding fire

1. The author has worked in the fire investigation department of the public security fire department for many years. After analyzing the fire accidents caused by electric welding in China and the working area, it is found that the main reasons for the frequent occurrence of electric welding fire are as follows:

1.1 the leaders and employees of the employing unit have weak fire safety awareness, and employ unlicensed welders without any management, There are hidden dangers in the accident. From the accident happened, many units and individuals have insufficient understanding of the fire risk of welding operation. They randomly employ unlicensed welders for welding operation, and do not take any protective measures before operation, and do not clean up after welding operation. Even if they do the preventive work, it is a mere formality, and the work is not thorough and meticulous, which leads to the occurrence of fire accidents

at 17:27 on April 21, 2002, a major fire accident occurred in a shoe industry Co., Ltd., resulting in a direct property loss of 535800 yuan. The fire was caused by the welding slag splashing into the iron trough of the funnel at the east end of the paint spraying water line, which ignited the paint fire when song * *, an unlicensed welder, was welding in the paint spraying workshop without safety protection. After investigation, the workshop director of the factory needs to carry out electric welding operation due to the installation of an exhaust fan in the paint spraying workshop of the factory. Because song * * did not receive professional training, he did not understand that the painting workshop was flammable and explosive; As the workshop director, Shi * * did not ask song * * whether he had welding qualification, nor did he clean up the inflammables for safety protection, so he let him carry out welding operation, which led to the fire

1.2 the electric welder does not follow the rules and regulations, and operates against the rules, leaving potential accidents. During the investigation, we found that some welders trained by the labor department did not work in strict accordance with the operating procedures during the welding process, and they had a fluke mentality during the operation. They turned a blind eye to the combustible, flammable and explosive materials around the operation site, resulting in the loss of national property. At 10:50 on June 30, 2002, a fire broke out at the construction site of a new No.1 blast furnace in an iron and Steel Co., Ltd., which destroyed a cooling tower of the blast furnace and caused a direct property loss of 260000 yuan. The fire was caused by the welding slag falling into the cooling tower’s internal heat dissipation material when the welder was welding at the top of the cooling tower. The construction unit in case of fire has strict examination and approval procedures for hot work, and the electric welder also has the electric welder certificate; But in the operation, the welders did not follow the rules and regulations, did not take fire protection measures, clearly knew that there was a gas pipeline not far away, and there was combustible material below, still held the mentality of trying, and took chances, which led to the fire< 1.3 the management of welding operation site is chaotic The second paragraph of Article 18 of the fire protection law clearly stipulates that "operators with fire risks such as electric welding and gas welding and operators of automatic fire protection system must work with certificates and strictly abide by fire safety operation regulations." Because the management and training of the labor department are all employees of large and medium-sized enterprises, but the individual operators who are idle in the society are not managed, and there is no organization to train them, which leaves hidden trouble of accidents 1.4 there is a gap in the requirements and operation procedures of national laws and regulations for welders. Generally, according to the possibility of fire and explosion accidents and the possible degree of harm, the fire is divided into three levels. The application for open fire operation shall be approved according to the fire grade. Relevant personnel shall go to the site for inspection and determination, formulate safety regulations for hot work, and implement relevant fire safety measures. According to the author’s experience in work in recent years, there are several deficiencies: 1. these requirements are not included in the regulations, but only explained in the interpretation of the fire protection law. Written in the training textbooks, from the perspective of jurisprudence and the application principle of law, the interpretation can not be used as a law. Administrative law enforcement can not be used as a basis. Therefore, these requirements are lack of operability2. These requirements are applicable to the units with regular fire safety management, and less restrictive to the units with poor management, small scale and even individual repair shop. 3. Some requirements are not specific and clear, rights and obligations are not clear, so that the responsibility of fire accident after fire can not be determined. For example: the division principle of three-level hot work is not clear; There is no specific department for approving the application of units and individuals for open fire operation; The responsibility of who will clean up the combustible materials on site is not clear; 1t is not clear who will carry out the inspection and determination of flammable and explosive places and confirm whether the hot work can be carried out. 1f these rights and obligations are not clear, once there is a fire, the public security fire department can not determine the responsibility of the fire accident according to the law. As a result, there is no relevant legal responsibility for violating these requirements China labor insurance net
