How can chemical industry companies do a good job in management during inspection and maintenance?
The key to management during the maintenance period of chemical industry companies lies in systematization, standardization, and full participation of all staff. Here are the specific points:
1? Preparation before maintenance and repair
Shutdown confirmation: Strictly implement the approved shutdown plan, and assign a dedicated person to confirm the key steps.
Material recycling and replacement: Flammable, explosive, and toxic materials are recycled or discharged according to regulations, and pipeline equipment is thoroughly purged and replaced.
Effective isolation: Complete the thorough isolation of the inspection device from the public system according to the isolation plan, and register the blind plate management number.
Sampling analysis: After ventilation of toxic and flammable substances inside the equipment, sample and analyze until qualified.
Plan preparation and delivery: Develop maintenance plans and handle equipment and facility delivery procedures.
Safety training and on-site confirmation: Conduct safety training for inspection personnel and confirm safety measures on site.
2? Safety management in maintenance and repair
Special operation management: Special operation personnel such as electrical and gas welding must hold certificates and be trained and qualified by their supervisors.
Labor protection dress code: All inspection personnel shall wear safety helmets, protective goggles, etc., and welders shall wear insulated gloves.
Safety training and on-site briefing: The hot work personnel and supervisors should be aware of the on-site risks and receive safety education before starting work.
Management of work permits: Standardize the management of work permits for hot work, confined spaces, etc.
Gas detection: Detect the concentration of flammable gases, toxic and harmful gases, and oxygen content before hot work, confined spaces, and other operations.
3? Clean up after inspection and maintenance
Restore the site: Restore the dismantled safety facilities and evacuate the tools and equipment in a timely manner.
Cleaning up waste: Clean up waste, debris, garbage, oil stains, etc.
4? Case Warning
Explosion caused by static electricity: The lack of anti-static measures resulted in sparks igniting flammable gases.
Pipeline corrosion and rupture: The pipeline transporting corrosive media has not undergone material upgrades and anti-corrosion treatment.
Reactor leakage accident: Failure to regularly test the sealing performance of the reactor.
