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, 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.
  • Spontaneous combustion of fine aluminum dust when ignition and fire sources are drawn in.

    E.g.: hot swarf, grinding sparks, cigarettes, etc.

  • Do not operate ignition and fire sources in the intake area of exhaust extraction unit.
