(V) Five, Jane answer (30 points, 10 points per subject) 1., the height of the work according to different fall height can be divided into what level, fall radius is respectively how much? Height is at 2-5M, work at level 1, and the falling radius is 3m. Height at 5-15m is two height operation, falling radius is 4m. Height at 15-30m is three height operation, falling radius is 5m. When the height is above 30m, the operation will be done at top grade, and the falling radius is 6m. 2. what are the unsafe factors of management? The labor organization is unreasonable, the operation regulations are incomplete, the training and education is not enough, the technical defects, personnel misuse, security risks and rectification are ineffective. 3. What are the main causes of fire accidents in construction sites? (1) welding operation; (2) waterproof construction; (3) electricity management, electrical equipment does not meet the requirements; (4) the smoking and burning of construction waste; (5) external factors lead to fire site, such as holiday fireworks, vandalism and other factors. Six, case analysis questions (30 points, 15 points per subject) 1., a construction team in the city along a street next to the demolition of a steel pipe scaffolding. The steel pipe is close to the building, and the street face is equipped with 10kV high tension line. The building is only 2M.. Because of the narrow street, it can not solve the problem that the distance is too close. It rained in the morning. The security officer told the construction workers how to operate, and asked the pole not to pull up. It should be lowered down. Afternoon after work, continue to work at the site two floor roof parapet of the Mason Ma Shiwen and general Liu Cunfu on the roof to pull the dismantled a steel pipe scaffold. After pulling up a distance, the horse and the horse, with the edge of the wall as the fulcrum, press the pipe diagonally to pull the pipe diagonally over the roof. Because the slope is too large, one side of the steel pipe touches the high tension line, when the wall is relatively wet, the pipe and the wall intersection point sparks, the wall will be the pipe burning bending 25 degrees. Ma Shiwen's chest near the burning pipe bend, wearing chemical fiber clothes, immediately burning up, the body burns. Liu Cunfu touched the pipe and burned his finger. Downstairs workers ran upstairs, put out the fire and sent the victims to the hospital. Ma Shiwen burns area of 50%, died due to respiratory and circulatory failure, and died at 12 p. m. on February 20th. Liu Cunfu burns an area of 25% and three fingers with disabilities. After investigation, the employer does not work instructions for the operation, operation without on-site supervision; Ma findings did not receive professional training and adequate safety training, Liu Cunfu from the countryside to the construction team in just 4 days. In view of the above-mentioned accident cases, the paper analyzes the immediate cause, indirect cause, responsible person and rectification measures. 1. direct cause (1) the unsafe state of things The HV line is too close to the building and the work space is short. (2) unsafe behavior of human beings The operation is not in accordance with the provisions of the method: the pole to pull on the cable; Defects in protective appliances: do not wear safety clothing. 2. indirect causes (management reasons) (1) the power supply is not cut off before the operation; (2) safety measures are not taken: the steel pipe is too close to the high tension line and no isolation measures have been taken; (3) operating procedures without dangerous operations; (4) the operation organization is unreasonable: Job arrangement is unreasonable: workers do not have the knowledge and ability to produce safety; Engaged in dangerous operations without on-site supervision. 3. responsible person (1) those directly responsible: Ma Shiwen, Liu Cunfu (2) leading responsibility: construction team leader, head of safety production (3) the main responsibility: construction team leader or the person in charge of production safety 4. corrective and preventive actions (1) to formulate procedures or instructions for dangerous operations, which stipulates that the operation of small space must be cut off by high-voltage lines, power supply or isolation measures, and special personnel are responsible for on-site supervision; (2) conduct rigorous business training and safety training for workers. 2., a security team member of the sub contractor with no safety belt, and no other safety measures, then climb the roof truss, replace the welder, B welded roof truss, angle steel and steel support. After 1 hours of work, workers take down C auxiliary angle steel material, because there is no assistant, a left support will be welded steel, right hand pliers, eyes closed operation. A first end point is fixed, and then left a fixed pivot end leaned forward to the other end of the welding steel. A just one with eyes closed, his left hand with steel because of solid is not strong, hold the weight of the human body suddenly taking off, and reinforced armor together fell from the 12.4m roof, was killed instantly. Please analyze the main cause of the accident and the main preventive measures. Main reason analysis (1) the deputy chief of the capital construction section is not a professional welder. Safety officer, non professional electrician (2) no guardian at the time of the accident. (3) the operator did not climb the safety belt, and no other safety facilities. Major preventive measures (1) non professional welders can not engage in welding and cutting operations. (2) a guardian shall be provided for climbing. (3) safety facilities such as standard fire safety belts and erection of safety nets must be used in climbing operations.
