Liquid nitrogen
Store liquid nitrogen only in small quantities and always in regulation containers without fixed covers.
Do not bring liquid nitrogen in contact with the body (eyes, hands), as this causes frostbite and numbing.
Protective clothing (including gloves and closed shoes) and protective goggles!
Ensure the room is well ventilated (88% contamination of breathing with nitrogen will result in 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 tanks 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 tanks 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!
Connecting devices and equipment must either be designed for this pressure or, if the permitted pressure for
the connecting 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 extracting chips!
The snout of the air nozzle is provided with a protective disc (e.g. rubber disc), which prevents air-borne
particles being reflected 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 tool is to be replaced!
Unauthorized use of compressed air, e.g. forcing flammable liquids (danger class AI, AII and B) out of
containers, results in a 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 explosion!
Do not blow dirty clothing with compressed air when being worn on the body.
Even compressed air at low pressure penetrates clothing and, if the jet is directed at the back, the air can enter
the anal cavity and fatally rupture the intestines!
Used oil
Used oil may contain health-threatening combustion residues.
Rub barrier cream into hands!
Wash hands after contact with used oil.
