HAZARDS INFORMATION CHART
| Hazards/effects |
Measures/regulations |
Repair stage 1: (replacement of bolted components, dent removal)
Repair stage 2: (repairs with bonding and riveting) |
- When a vehicle outer skin is ground, aluminium dust accumulates in small amounts. This dust can be removed with conventional exhaust extraction unit.
|
Repair stage 3: (repairs with welding)
- Explosion hazard due to high concentration of fine aluminium dust.
Arising e.g. during straight-through grinding of coated components in the base material and large-surface grinding of bright-finish components.
- Explosion hazard due to swirling up of fine aluminium dust in cavities.
Created by the necessary, thorough cleaning of machining surfaces and tools before and after machining aluminium.
|
- Avoid high concentration of fine aluminium dust by means of continuous extraction.
- Use explosion-proof exhaust extraction unit
- Do not use compressed air when cleaning the work bay.
- Avoid swirling up dust when cleaning the work bay.
