When carrying out heat treatment experiments there must always be at least two people in the room.
The performance of heat treatment experiments is allowed only after appropriate training by the competent FB 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, ...) must be worn at all times.
Attention! Danger of fire when quenching in the oil tank! To put out the fire (by stifling/choking it), the cover of the quenching tank should be closed immediately.
In the laboratory a fire alarm intervention device is installed. This device is set up so there is one minute in which to confirm the alarm and, after this confirmation at the console (near the lift door), a further five minutes to decide if the alarm is real or not and if necessary cancel it. If the confirmation time of one minute passes without the alarm being confirmed at the console the alarm is transferred to the fire brigade. If the alarm is confirmed within one minute but then the further five minutes is allowed to pass the alarm is also transferred to the fire brigade.
Should any problems or deviations from the planned test sequence be encountered when working alone, then a member of staff or a technician familiar with the installations of a scientific project team 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 still be very hot (600 ° C) and should therefore not be touched without checking the temperature first.
The protective gases can be suffocating/asphyxiating. Operation of the furnaces with protective gas is therefore only allowed if the ventilation is always turned on. This must be constantly checked.
In closed furnaces ventilation can be reduced to half power during the night.
