  1. Aluminium 
    Hazards/effects Measures/regulations
    Repair stage 1 and 2:
    No hazards/effects
    none
    Repair stage 3: (Welding - only E52)
    • 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.
    • Spontaneous combustion of fine aluminium dust when ignition and fire sources are drawn in.

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

    • Do not operate ignition and fire sources in the intake area of exhaust extraction unit.
  2. Carbon 
    Hazards/effects Measures/regulations
    Repair stage 1:
    No hazards/effects
    none
    Repair stage 2 and 3:
    • Explosion hazard due to high concentration of carbon dust.

      Produced when grinding carbon.

    • Explosion hazard due to swirling up of carbon dust in cavities.

      Created by the necessary, thorough cleaning of machining surfaces and tools before and after machining carbon.

    • Avoid high concentration of carbon dust by drawing it off continuously.
    • 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 carbon dust when ignition and fire sources are drawn in.

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

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