Second, the work place: around the chute, plate filter press sludge scraper within below coal plant Third, the operation content: cleaning, maintenance of the chute and slime scraper 4. Operating unit: production class and bench work class of coal preparation plant V. Person in charge of construction: responsible person of post personnel safety: squad leader Sixth, safety technical measures: (1) Preparation before work 1. Wear protective clothing such as masks, helmets, gloves, etc. 2, before the job is to be ready to clean up the chute, overhaul the short and long iron to a small shovel and spade, pickaxe, wrenches, hammers and other hand tools and instruments and slime scraper chute are used. If you need electric welding and gas cutting, you need to prepare the tool materials such as lining, welding machine, welding rod, welding rod, electric welding gloves and goggles in advance. 3. To repair the slime scraper, you need to contact the electrician to connect the lighting facilities in advance. 4. Prepare safety tools such as safety ropes, safety belts, etc. before operation and ensure that they are in good condition. 5. The barrier should be set above the chute and the slime scraper, and the floating coal and debris above the chute and the coal scraper should be cleaned to prevent the debris from being injured during the operation. 6. Before the operation, the chute, the slime scraper itself and the upper and lower related equipment should be powered off and the safety lock should be installed. 7. All operators must carefully study the contents of this measure and work after passing the training. (2) Safety technical measures during the operation 1. When personnel need to enter the chute and coal slime scraper, they must wear seat belts and safety ropes. The seat belts or safety ropes must be fixed firmly. One person must be left outside the chute and the slime scraper to be optimistic about the work space to prevent debris from falling into the working space. 2. The job site must ensure one person's operation and one person's supervision. 3. When cleaning up the floating coal in the chute, overhauling the chute and the slime scraper, no one shall throw any objects into the working space. 4. When the chute and the slime scraper need to transfer tools inside and outside, the hand must be handed over, and it is strictly forbidden to throw objects. 5. When cleaning and stacking the floating coal in the chute, the operator must stand firm and avoid the direction in which the accumulated floating coal in the chute may fall. 6. When repairing the slime scraper, if you need to replace the scraper, scraper chain and other objects, you need to carry it under the command, the command should be unified, the password should be clear, and the scraping stick, scraper chain and other objects fall and hurt; if it involves replacement scraping When working with sticks, scraper chains, etc., the operator should guard against sticking hands and other body parts. 7. During the process of repairing the chute, if the chute lining is to be replaced, and the materials needed to replace the lining are to be lowered into the chute, the work site shall be unified and the password shall be clear to prevent the material from falling and injuring during the lowering process. 8. When using the short handle, long handle and other tools to pile up the floating coal in the operation of the chute, the operator should be placed on the side of the top, and the equipment should not be placed against the body to prevent the objects in the warehouse from falling suddenly. The reaction force hurts the human body. 9. During the process of cleaning the chute, overhauling the chute and the slime scraping, it is strictly prohibited to cross the work at the same time. 10. When cleaning and stacking the floating coal at the chute, the operator is strictly forbidden to check the condition of the chute in the chute when the chute tool is not taken out, and prevent the worker from accidentally injuring the worker when the floating coal is accumulated on the wall of the chute. 11. The personnel entering the chute must always be careful of the chute and the floating coal suddenly falls and crushes the body parts such as the legs and feet. 12. During the operation, it is necessary to ensure that the equipment associated with the chute and the slime scraper is powered off and the safety lock is on. If the chute, the slime scraper itself and the upper and lower related equipment are to be opened during the operation, the operator must contact the dispatcher of the coal preparation plant, and the dispatcher can ensure that the chute and scraper can be opened when there is no work. The chute and the slime scraper must be powered off immediately after the equipment is stopped and the safety lock is applied. 13. When welding and gas cutting operations are involved in the operation of the inspection chute and the slime scraper, the relevant provisions of the "Safety Technical Measures for Electric Welding and Gas Cutting" shall be strictly observed. Seven, finishing work: 1. After the operation is completed, the site must be cleaned up, and the presence or absence of tools in the chute and slime scraper should be checked. After the workers leave the chute, the number of tools used can be counted again. 2. After the operation is completed, the on-site operators will report to the squad leader the situation of the chute cleaning. 5-Layer FFP2 Particulate Respirator 5 Layers Filter FFP2 Mask,5 Layers Particulate Respirators,5 Layers Filter Disposable Ffp2 Mask,Nonwoven 5 Layers Particulate Respirators Henan Aklly Filter Engineering Co., Ltd , https://www.akllyfilte.com
