• Ensure that the room is well ventilated. Nitrogen concentration exceeding 88% of
breathing air leads to suffocation.
• Avoid all knocks and jars to the containers, fixtures or workpieces.
Compressed air
Compressed air is air compressed at excess pressure and is stored in vessels from which it can be extracted.
The pressure at which the air is kept can be read off at pressure gauges which must be connected
to the compressed air vessels and the compressed air lines.
When working with compressed air, safety precautions must be constantly observed:
• Pay special attention to the pressure level in the compressed air network and pressure vessel!
• Devices and equipment connected must either be designed for this pressure or, if the permitted
pressure for the connected elements is lower than the pressure required, a pressure reducing
valve and safety valve (set to permitted pressure) must form an intermediate connection. Hose
coupling and connections must be securely attached!
• Always wear protective goggles when blowing off tools or chips!
• The snout of the air nozzle should be provided with a protective disc (e.g. rubber disc), which prevents
air-borne particles being deflected and thereby prevents injury to eyes.
• First shut off compressed air lines before compressed air equipment is disconnected from the
supply line or before equipment or tools are exchanged!
• Unauthorized use of compressed air, e.g. forcing flammable liquids (hazard class AI, AII
and B) out of containers, carries the risk of explosion!
• Forcing compressed air into thin-walled containers (e.g. containers made of tin, plastic and glass)
for drying purposes or to check for leaks, results in a risk of shattering!
• Do not use compressed air to clean contaminated clothing whilst it is being worn.
Used oil
Used oil may contain health-threatening combustion residues.
Rub barrier cream into hands!
