Core changes in the standard revision
Dimensions 2011 Edition 2023 Edition Technical differences Equipment safety Only basic centrifuges are specified Added interlock protection for tiltable fully automatic coating machine and planetary fully automatic coating machine Added 5 requirements such as anti-fall device and power-off interlock Pretreatment General shot blasting requirements Specify anti-slip floor + 1.2m fence + 10m fire-free zone Refine the protection level of mechanical rust removal sites Hazard control Dispersed in multiple chapters Added Chapter 10 Special Management of Hazardous Waste Establish storage ledger + professional agency recycling system
Key process safety points
4.4 Mechanical rust removal operation
Shot blasting machine operation must meet three levels of protection:
1) Anti-slip floor basic protection
2) The operating platform is set with a fence ≥1.2m
3) Open flames are strictly prohibited within an operating radius of 10m6.1 Immersion-centrifugal method
New class=instrument>Planetary fully automatic coating machines must be equipped with:
• Physical closure of the hoardings
• Door machine power-off interlock device
• Lifting paint cylinder anti-fall mechanism
New regulations on hazardous waste management
Case: A company did not store zinc and aluminum dust in a special warehouse, which caused a hydrogen explosion when it came into contact with moisture. The new standard requires:
1) Dust should be stored separately and kept dry
2) A yellow sand box should be installed next to the dust collector
3) Disposal should be entrusted to an organization with hazardous waste treatment qualificationsImplementation suggestions
- Upgrade the interlocking system of automated equipment, and focus on checking the 45° tilt safety limit of the tiltable coating machine
- Establish an electronic record of hazardous waste to record inbound and outbound data and disposal vouchers
- Install a temperature alarm device in the dichloromethane solvent storage room to ensure ≤30℃
Technology evolution analysis
The standard reflects three major trends:
1) Automation substitution: Two new types of fully automatic equipment specifications are added to reduce the risk of manual intervention
2) Full process control: Form a closed-loop management from coating preparation to hazardous waste disposal
3) Precise protection: Differentiated requirements are formulated according to different process characteristics (such as the shearing furnace pressure of 0.05-0.2MPa)
