Explosion-proof electrical appliances paint, maintenance precautions
Explosion-proof electrical equipment maintenance and painting require high precision and strict adherence to safety protocols. Every step in the process must be carefully followed, and shortcuts should never be taken, even if the procedures seem complex. When applying anti-rust or protective paint, it is crucial to avoid any contamination of the explosion-proof surfaces, as this could compromise the equipment's integrity and safety.
Before proceeding with any repairs, it is essential to inspect and test the explosion-proof performance according to the specified standards. All key parameters should be recorded. If the equipment fails the test, the cause must be identified, and the necessary repairs performed. This process should continue until the equipment meets all required specifications. Once the electrical tests are successfully completed, a certificate of inspection and maintenance should be issued, signed, sealed, and stored in the inventory for future reference.
A clear maintenance responsibility system must be enforced—those who perform the maintenance are also responsible for its quality. Each technician should conduct thorough inspections in accordance with established standards. Any equipment that cannot be safely repaired or is too damaged to restore to a safe condition must be scrapped. Proper markings should be applied, and the equipment should be moved to a designated disposal area.
After every overhaul, detailed maintenance records and test reports must be compiled and kept on file. Each piece of explosion-proof equipment should be assigned a unique number for tracking purposes, and a repair file should be created. The file should include the equipment number, type, date of repair, inspection details, replacement of critical components, settings of safety devices, rated current values of fuses, and other relevant information. It should also include the signatures of those involved in the maintenance process.
All tools, instruments, and materials used during the work must be accounted for and properly stored. The work area should be kept clean and organized. No electrical equipment should be left unattended at the worksite; it must be properly parked and secured before leaving the location.
