Technical data

1–08 Safety

• Do not store combustible substances, e.g. oils and greases, within 5 m of the working area!

• Under no circumstances should clothing be oily or greasy.

• Do not allow vapors to penetrate clothing! Oxygen enrichment in fabric can cause

working clothes to ignite suddenly!

• After working with liquid oxygen, do not smoke until clothing is free of vapors!

• Avoid all knocks and jars to the containers, fixtures or workpieces.

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.

• Wear protective clothing, including gloves and closed shoes, and protective goggles!

• 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 tanks f rom 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 i n 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.

Used oil

Used oil may contain health

-threatening combustion residues.

Rub barrier cream into hands!

Wash hands after contact with used oil.
