Hazards/effects Measures/regulations
REPAIR STAGE 1 :

  • 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 workbay.
  • Avoid swirling up dust when cleaning the workbay.
