Hazardous fumes and vapours

Welding Fume

ist is hazardous to health because:
  • it is respirable
  • contains carcinogenic substances such as nickel oxides and chromates ( the welding from high Cr / Ni - containing alloys or filter metal )
  • contains radioactive thorium ( TIG welding with thorium-containing tungsten electrode )
Metal dust

can lead to illness and diseases of pulmonary fibrosis.
As sources of danger in particular:
  • Dust during grinding and mixing of the raw materials ( carbides )
  • Fumes and smoke during metal smelting in sintering , i.e. in reducing, carburizing, presintering and final sintering of the starting materials or intermediates
  • Dusts during roughing, drilling, sawing and grinding of sintered parts
  • Dusts during fine machining of sintered material and tools such as grinding with diamond or corundum wheel

Grinding dust

Imposes a pollution of the breathing air. Besides health hazards, explosion hazard eminates from grinding dust. Certain wood dust may have sensitizing (allergic) or even carcinogenic effects on humans.

KORA supports surely by eliminateing these hazardous substances from your working place.
We offer you the proper protective measures against these problems in terms of:
  • Extraction systems direlctly at the source
  • Technical measures such as extraction arm, welding tables with integrated extraction or fixed hoods
  • Inlet and outlet exhaust systems such as "level ventilation", in which the air supply comes from the bottom and the fumes extraction occurs at the ceiling level.

Filter systems
