| 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, aluminum 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 aluminum 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 aluminum dust in cavities.
Created by the necessary, thorough cleaning of machining surfaces and tools before and after machining aluminum.
|
- Avoid high concentration of fine aluminum dust by means of continuous extraction.
- Use explosion-proof exhaust extraction unit
- Do not use compressed air when cleaning the workbay.
- Avoid swirling up dust when cleaning the workbay.
|
|
|
- Do not operate ignition and fire sources in the intake area of exhaust extraction unit.
