  1. Aluminum 
    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 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 shavings, grinding sparks, cigarettes, etc.

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

      Produced when grinding Carbon Fiber Reinforced Plastic.

    • Explosion hazard due to build up of Carbon Fiber Reinforced Plastic dust in cavities.

      Created by the necessary, thorough cleaning of machining surfaces and tools before and after machining Carbon Fiber Reinforced Plastic.

     
    • Avoid high concentration of Carbon Fiber Reinforced Plastic dust by suctioning 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 Fiber Reinforced Plastic dust when ignition and fire sources are drawn in.

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

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