Safety precautions for the maintenance and repair of reaction vessels

Thread Content

Precautions for maintaining safety: 1. Operators must work with a valid certificate. 2. Wear the required safety protective equipment; in areas with toxic or harmful substances, appropriate protective gear must be available for emergency use. 3. Do not wash the motor, reducer, insulation layer, instruments, and equipment directly with water. 4. Do not clean or wipe the moving parts while the equipment is in operation. 5. Bolts must not be tightened or loosened under pressure, nor must pressurized components be repaired. Safety precautions for maintenance work: 1. Specialized workers must possess the appropriate qualification certificates for their tasks. 2. The equipment must be handed over safely in accordance with the regulations. 3. It is necessary to wear the required safety protective equipment; in environments with toxic or harmful substances, appropriate protective gear must be available for emergency use. 4. Turn off the power supply and hang a “Do Not Close” warning sign. 5. When maintaining the tank containing flammable, explosive, toxic, or corrosive substances, it is necessary to shut off the inlet and outlet valves, install isolation blind plates, and carry out cleaning and purging. Work can only proceed after sampling and analysis show that the conditions are satisfactory. 6. A permit for work inside the tank is required for such operations. If the work is interrupted for an extended period due to certain reasons or if the safety conditions change, a new permit must be obtained before continuing the work inside the tank. 7. For operations inside the tank, ventilation measures should be taken depending on the specific working conditions. For tanks with poor ventilation or a small volume, intermittent operation should be employed; continuous operation under force is not allowed. 8. For work inside the tank, safety ladders and platforms must be set up according to the depth of the tank, a supervisor must be assigned, and rescue ropes must be provided to ensure emergency evacuation. The guardian shall not leave their supervisory post without permission. 9. A fire work permit is required for performing hot work. When leaving, the welder must not leave the acetylene torch inside the tank to prevent acetylene leakage. 10. Temporary lights for maintenance purposes should use a low voltage of 36V, while the lighting fixtures inside the tank must be explosion-proof lamps with a voltage not exceeding 24V. When the supply voltage of testing instruments and repair tools exceeds 24V, protective measures must be taken to prevent direct contact with live parts. Safety precautions for testing 1. Testers should wear the prescribed safety protective equipment. 2. Persons not related to the test drive should leave the test site. 3. During the testing process, the testers must not leave their posts arbitrarily. 4. During the testing process, the personnel in the operation and control position must maintain good communication with those on site; in the event of any abnormalities, the machine should be stopped promptly for inspection and troubleshooting. 5. When manually turning the shaft, the power supply must be cut off and the V-belt removed.
