WBH (Heat Treatment Laboratory)

PSE to use for work in WBH:

  • Closed footwear
  • Safety goggles or face shield
  • Helmet with visor
  • Heat protection gloves
  • Heat protection coat
  • Heat protection gaiters

When carrying out heat treatment experiments there must always be at least 2 people in the room.

The performance of heat treatment experiments is allowed only after appropriate training by the competent department technician or an appropriately trained member of the project staff.

For the manipulation (insertion, removal ...) of samples in a hot oven full protective clothing (helmet with face shield, coat, leggings, fixed (closed) shoes, gloves = PSE) must be worn at all times.

Attention! Danger of fire when quenching in the oil tank! To put out the fire (by suffocation), the cover of the quenching tank should be closed immediately.

Due to the formation of smoke the fire alarm can be temporarily switched off to avoid false alarms. After completion of the tests however the smoke alarm must be reactivated.

Should any problems or deviations from the planned test sequence be encountered then a member of staff or a technician familiar with the installations must be informed. Independent changes to the test set are to be avoided for safety (for man and machine) reasons.

Attention! Metal parts which no longer glow, can yet still be very hot (600°C) and should therefore not be touched without checking the temperature first.

The protective gases can cause asphyxiation. Operation of the furnaces with protective gas is therefore only allowed if the ventilation is always turned on. This must be constantly checked.

If the experiment is carried out in closed furnaces ventilation can be reduced to half power during the night.

The use of gas cylinders has to be carried out with the utmost care. Gas cylinders must be properly secured.
