According to the objective requirements of safety management, the high altitude work vehicle management system applies the movement law of safety and accident and the law of accident prevention and control. In order to change the abnormal behavior of people, the abnormal state of things and the abnormal combination of people and things, it can effectively prevent and control falling accidents from height in essence, which is divided into specific prevention Control and comprehensive prevention and control.

1. Specific prevention and control of falling accidents specific prevention and control of falling accidents is to put forward specific prevention and control points for each type of falling accidents according to the specific causes of different types of falling accidents. (1) Key points for prevention and control of falling accidents at the entrance: solid and effective safety protection facilities (cover plate, fence and safety net) must be set at the prevention opening, passage opening, stair opening, elevator opening and loading platform opening; If the protective facilities at the entrance are damaged, they must be repaired in time; It is forbidden to move or dismantle the protective facilities at the entrance without authorization; Be careful when operating near the hole, and do not work back to the hole; Do not rest near the hole, make trouble, cross the hole or walk on the cover plate of the hole; At the same time, eye-catching warning signs must be hung at the opening. (2) Prevention and control points of falling accidents on scaffolds; Scaffolds shall be erected and scaffold boards shall be paved as required, and probe boards are not allowed; The protective railings shall be bound firmly and the safety net shall be hung; The load of scaffold shall not exceed 270Kg / m2; If the scaffold is too wide from the wall, safety protection shall be added; The scaffold erection acceptance and use inspection system shall be implemented, and the problems found shall be handled in time. (3) Key points for prevention and control of falling accidents of suspended work at heights: strengthen the construction plan and the cooperation of various construction units and types of work, make full use of safety facilities such as scaffolding, and avoid or reduce suspended work at heights; Operators shall be more careful to avoid excessive force and instability; Operators working at heights must wear soft soled anti-skid shoes and correctly use safety belts; It is not suitable to engage in suspended high-altitude operation due to physical illness, excessive fatigue and low spirit. (4) Key points for prevention and control of roof cornice falling accident: Operators on the roof shall wear soft soled anti-skid shoes; Anti skid measures shall be taken when the roof slope is greater than 25 °; When working on the roof, do not move back to the cornice; The external scaffold shall be used for construction. The external vertical pole shall be 1.2m higher than the cornice, and the safety net shall be hung. The external scaffold of the cornice shall be covered with scaffold board; If no external scaffold is used for construction, a safety net shall be set under the eaves. 2 comprehensive prevention and control of falling accidents comprehensive prevention and control of falling accidents is the key point of comprehensive prevention and control of falling accidents according to different categories and series of cause laws of falling accidents. (1) For personnel engaged in high-altitude operation, regular safety publicity and education and safety technology training shall be carried out to make them understand and master the laws and hazards of high-altitude falling accidents, firmly establish safety ideas and have the ability to prevent and control accidents, strictly implement safety laws and regulations, and when it is found that they or others have abnormal behaviors of illegal operation, Or in case of abnormal conditions of objects and protective measures related to high-altitude operation, they shall be changed in time to meet the safety requirements, so as to prevent and control high-altitude falling accidents. (2) The physical condition of personnel working at heights shall meet the safety requirements. For example, personnel with hypertension, heart disease, anemia, epilepsy and other unsuitable for high-altitude operation are not allowed to engage in high-altitude operation; Stop working at heights for personnel with excessive fatigue, low spirit and low mood; It is forbidden to work at heights after drinking. (3) Personal dress of personnel working at heights shall meet safety requirements. For example, safety helmet, safety belt and relevant labor protection articles shall be provided according to actual needs; Do not wear high heels, slippers or work barefoot; Wear soft soled anti-skid shoes when working at heights in the air. It is not allowed to climb the scaffold or take the basket of the material well frame, or jump up and down from a high place. (4) Various scaffolds shall be erected according to the specified requirements. For example, when the shelf height reaches more than 3m, two guardrails shall be bound on each floor, a toe board shall be set, the scaffold board shall be paved tightly, the board head and row wood shall be bound firmly, and the probe board shall not be left. When using bridge scaffold, special attention shall be paid to whether the bridge pile and wall are firmly and properly jacked. When raising and lowering the bridge, the safety rope shall be hung, and the lifting at both ends of the bridge shall be kept synchronous. Workers lifting the bridge shall hang the safety belt on the column of the bridge. The sling tools for lifting the bridge shall comply with the provisions of design standards and safety regulations. When using the hanging basket rack and hanging rack, the lifting sling must be firm. When the hanging basket rack is in use, it is also necessary to hang the safety rope or safety fixture. When lifting the basket, the safety rope shall be adjusted with the lifting and shall not be removed. Both sides and outside of the hanging basket rack and hanging rack shall be tightly sealed with nets. Head net or head protection shed shall be set on the top of the hanging basket, and a protective fence shall be bound on the inner side of the hanging basket, and toe boards shall be set. Chain blocks and hand block hoists for lifting bridge frames and hanging baskets can only be used after passing the appraisal of the technical department. The chain fall shall be at least 2T, the hand block hoist shall be at least 3T, and the load-bearing steel wire rope and safety rope shall be steel wire rope with a diameter of more than 12.5mm. In addition, it is strictly prohibited to overload the socket frame, hanging basket and bridge frame. (5) A safety net shall be set according to the specified requirements. For construction projects above 4m, a safety net with a width of 3 ~ 6m shall be set on the first floor of the building. In case of high-rise construction, a 3M wide fixed safety net shall be supported every four floors above the safety net on the first floor. If the vertical net is used for protection on the construction layer, it shall be ensured that the vertical net is more than 1m higher than the building, and the vertical net shall be overlapped tightly. The specification and quality shall be guaranteed, and the use shall be safe and reliable. (6) Do a good job in safety protection at the entrance. The specific method is the same as the prevention and control measures of portal falling accident. (7) When using high stool and ladder, only one person is allowed to operate on a single ladder, and the supporting angle is 60 ° ~ 70 °. Anti skid measures shall be taken for the lower foot of the ladder. When erecting herringbone ladder, the included angle of the two ladders shall be maintained at 40 °, and the two ladders shall be firm. No person is allowed to stand on the ladder when moving the ladder. When using high stool, only one person is allowed to stand on a single stool. After the double stool is supported, the distance between the two stools shall not exceed 3M. If higher ladders and benches are used, corresponding safety measures shall be taken as required. (8) When there is no reliable protective facilities, safety belt must be worn for high-altitude operation, otherwise it is not allowed to work at heights. At the same time, the quality of safety belt must meet the safety requirements for use, and it is necessary to hang it high and use it low.
