MTU 12 V 2000 M72 Operating Instructions Manual page 14

Lead
• When working with lead or lead-containing pastes, avoid direct contact with the skin and do not inhale
lead vapors.
• Adopt suitable measures to avoid the formation of lead dust!
• Switch on fume extraction system.
• After coming into contact with lead or lead-containing materials, wash hands!
Acids and alkaline solutions
• When working with acids and alkalis, wear protective goggles or face mask, gloves and protective
clothing.
• Immediately remove clothing wetted by acids and alkalis!
• Rinse injuries with plenty of water!
• Rinse eyes immediately with eyedrops or clean tap water.
Painting
• When painting in other than spray booths equipped with extractors, ensure good ventilation. Make
sure that adjacent work areas are not affected.
• No naked flames!
• No smoking.
• Observe fire prevention regulations!
• It is absolutely necessary to wear masks providing protection against paint and solvent fumes.
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 numb‐
ing.
• Wear protective clothing, gloves, closed shoes and protective goggles!
• Ensure the room is well ventilated. 88% contamination of breathing air with nitrogen will result in suffo‐
cation.
• 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 extract‐
ed.
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 pres‐
sure 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. sheet metal, plastic, glass) for drying purpos‐
es or to check for leaks will result in a risk of bursting!
• Do not blow dirty clothing with compressed air when being worn on the body.
