High altitude work vehicle management system (high altitude work vehicle) applies safety and accident movement laws and laws to prevent and control accidents in accordance with the objective requirements of safety management, in order to change the abnormal behavior of people, the abnormal state of objects, and people and things. Anomalous combination, in essence, advance prevention and control of falling accidents in high places, is divided into specific prevention, control, and comprehensive prevention and control.
1 The specific prevention and control of falling accidents at high places
The specific prevention and control of high-fall accidents is based on the specific causes of falling accidents of different types and heights, and specific prevention and control points for each type of high-fall accidents are proposed.
(1) Prevention and Control Points for Falling Accidents in the Caverns: Preventive openings, access openings, stairways, lift openings, and loading platform openings must be provided with solid and effective safety protection facilities (covers, fences, and safety nets). Hole protection facilities must be promptly repaired if any damage is found; hole protection facilities are strictly prohibited unauthorized shifting, demolition; be careful in the operation of the hole, should not be back to the hole operation; do not rest next to the hole, play or across the hole and cover from the hole Walk on the board; at the same time the hole must also be set up with prominent warning signs.
(2) The prevention and control points of falling accidents on scaffolds; scaffolding shall be erected in accordance with the regulations, and the scaffolding shall be paved; no probe plate shall be allowed; the guard rails shall be firmly tied and the safety net shall be hung; the scaffold load shall not exceed 270 kg/m2; scaffolding The safety protection shall be added to the excessively wide walls, and the acceptance and use inspection system shall be implemented for scaffolding, and problems shall be solved in time.
(3) Preventing and controlling the falling accidents at high altitudes: strengthen the construction plan and cooperation with each construction unit and each type of work, make use of scaffolding and other safety facilities as much as possible to avoid or reduce the operation at high altitude; Operators should take extra care to avoid excessive force. Fierce, physical instability; suspended workers must wear soft bottom anti-skid shoes, while the correct use of seat belts; physical illness or fatigue, lack of energy, etc. should not be engaged in high altitude operations.
(4) The main points of prevention and control of roof falling accidents are: Workers on the roof should wear non-slip shoes with soft soles; anti-skid measures should be taken when the roof slope is greater than 25°; mobile operations should not be carried on the roof facing the roof; use foot scaffolding works For construction, the poles outside the row should be 1.2m higher than the cornices, and safety nets should be hung. The outer scaffolding should be covered with scaffolding boards. Without the use of external scaffolding construction, a safety net should be set up under the eaves.
2 Comprehensive Prevention and Control of Falling Accidents in Height
The comprehensive prevention and control of high-level crashes is the basis for comprehensive prevention and control of high-fall accidents based on the different types and series of causes and laws of high-fall accidents.
(1) For personnel engaged in high places, they must insist on carrying out regular safety propaganda and education and safety technical training so that they can understand and master the laws of accidents at high altitudes and the hazards of accidents, firmly establish safety ideology, and have the ability to prevent and control accidents. When strict enforcement of safety laws and regulations, when discovering abnormal behavior of oneself or others in violation of regulations, or discovering abnormal conditions associated with objects and protective measures related to work at height, it is necessary to change them in time to meet safety requirements so as to prevent and control them. A falling accident occurred at a high altitude.
(2) The physical conditions of high altitude workers must meet the safety requirements. For example, people with high blood pressure, heart disease, anemia, epilepsy, etc. are not allowed to work in high places; those who are over-fatigue, lack of energy and low morale need to stop working at heights; After working in high places.
(3) Personal dress for high-level workers must meet safety requirements. For example, according to the actual needs of the helmet, safety belt and related labor protection supplies; not allowed to wear high heels, slippers or barefoot work; if it is suspended high altitude work to wear soft-soled shoes. It is not allowed to climb a scaffold or to go up and down with a basket, nor to jump up and down from a height.
(4) All kinds of scaffolding should be supported as required. For example, when the shelf height reaches 3m or more, two guard rails shall be tied on each floor, a file legplate shall be provided, and the scaffolding shall be laid tightly. The heads and rows of wood shall be tightly fastened, and probe boards shall not be allowed.
When using bridge scaffolding, special attention should be paid to whether the bridge pile and the wall body are pulled firmly and Zhou Zheng. When lifting the bridge to drop the bridge, it is necessary to hang the safety rope and keep the lift at both ends of the bridge synchronized. Workers lifting the bridge to hang the seat belts on the bridge uprights. Lifting bridge sling tools must meet the design standards and safety regulations.
When using shelf baskets and hanging racks, their slings must be secure. When the shelf is in use, it is also necessary to hang a safety rope or safety clamp. When lifting the basket, the safety rope must be adjusted with the lift and must not be removed. Both the side and the outside of the hanging shelf and hanging shelf must be sealed with a net. The top of the basket should be equipped with a head net or head guard. A side rail should be tied to the side of the basket and a file should be provided.
Lifting bridges, baskets and chain hoists must be certified by the technical department before they can be used. At least 2t is used for the reverse chain, and at least 3t is used for the hand hoist. The steel wire rope with a diameter of 12.5mm or more is used for load-bearing steel ropes and safety ropes. In addition, it is forbidden to overload the socket rack, basket and bridge rack.
(5) To set up a safety net in accordance with the requirements, a safety net with a width of 3 to 6 meters should be set up on the first floor of the building for any construction work of more than 4 meters. If high-rise construction is conducted, a 3m-wide fixed safety net will be required at every fourth floor above the first-floor safety net. If the construction layer is protected by a vertical grid, it shall ensure that the vertical grid is more than 1m above the building, and the vertical grid shall be tightly lapped. And to ensure the quality of specifications, the use of safe and reliable.
(6) We must do a good job in the safety protection at the entrance. The specific method is the same as the prevention and control measures for accidents at the entrance to the cavern.
(7) When using high stools and ladders, only one person is allowed to operate on a single ladder. The angle of support is 60°~70°. The anti-skid measures shall be taken on the feet of the ladder. When supporting the word ladder, the angle between the two ladders shall be Keep 40°, and the two ladders should be firm. When the ladder is moved, no one can stand on the ladder. When a high stool is used, only one person is allowed to stand on a single stool. After the pair of stools are opened, the distance between the two stools shall not exceed 3m. If higher ladders and high stools are used, corresponding safety measures should be taken as required.
(8) In the absence of reliable protective facilities, work at high altitudes must be worn, otherwise work at heights is not allowed. At the same time, the quality of the seat belts must meet the safety requirements for use, and they must be used at high levels.
Rotary die cutting is a popular form of die cutting. This method uses a cylindrical die that turns continuously paired with an anvil cylinder. The press feeds thin, flexible material, also known as web, between these two cylinders. The die's cutting edge pinches the material against the anvil cylinder, producing clean cuts or perforations. Rotary die cutting is exceptionally fast, precise and versatile, making it a good choice for many applications.
