Lead Adopt suitable measures to avoid the formation of lead dust. Switch on extraction system. When working with lead or lead-containing compounds, avoid direct contact to the skin and do not

inhale lead vapors. Wash hands after contact with lead or lead-containing substances.

Compressed airObserve special safety precautions when working with compressed air: 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. Wear goggles when blowing off components or blowing away chips. 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 bursting. Pay special attention to the pressure level in the compressed air network or pressure vessel. Assemblies or products to be connected must either be designed for this pressure, or, if the permit-

ted pressure for the connecting elements is lower than the pressure required, a pressure reducingvalve and safety valve (set to permitted pressure) must form an intermediate connection.

Hose couplings and connections must be securely attached. Provide the snout of the air nozzle with a protective disk (e.g. rubber disk). First shut off compressed air lines before compressed air equipment is disconnected from the supply

line, or before the equipment or tool is to be replaced. Carry out leak test in accordance with the specifications.

Paints and lacquers Observe the relevant safety data sheet for all materials. When carrying out painting work outside the spray stands provided with fume extraction systems,

ensure that the area is well ventilated. Make sure that neighboring work areas are not impaired. Avoid open flames in the vicinity. No smoking. Observe fire prevention regulations. Always wear a mask providing protection against paint and solvent vapors.

Liquid nitrogen Observe the relevant safety data sheet for all materials. Store liquid nitrogen only in small quantities and always in specified containers (without fixed cov-

ers). Avoid body contact (eyes, hands). Wear protective clothing, protective gloves, closed shoes and protective goggles. Make sure that working area is well ventilated. Avoid all knocks and jars to the containers, fixtures or workpieces.

Acids/alkaline solutions/urea solution (AdBlue, DEF) Observe the relevant safety data sheet for all materials. When working with acids and alkaline solutions, wear face mask, gloves and protective clothing. Do not inhale vapors. If urea solution was swallowed, rinse mouth and drink plenty of water. If the solutions was spilled onto clothing, remove the affected clothing immediately. In case of skin contact, rinse parts of the body thoroughly with clean water. Rinse eyes immediately with eyedrops or clean tap water. Seek medical attention as soon as possi-

ble.

Special unions

The following types of union are spray-proof in case of leakage even without covers and have been con-firmed as being SOLAS-compliant by GL and DNV.Plug-in pipe unionDesign precludes lateral spray as the parting line is shielded by the sleeve (4).Only seepage along the pipeline is possible whereby the pressure is greatly reduced by a faulty O-ring(3).The union is confirmed as being SOLAS-compliant by DNV and GL.Plugs and sensorsScrew-in plugs (2) are sealed toward the outside either with a copper sealing ring (1), according to DIN,or an O-ring (ISO).The fluid must first pass the thread in case of a loose threaded union or faulty sealing ring (2).The pressure is so greatly reduced by this and the faulty sealing ring (2) that any leakage is not underpressure.

The HP fuel line is sealed by the thrust ring (8).If leakage in the area of the thrust ring (8) or the HP line (5) occurs, the emerging fuel is routed to theleakage chamber.Leak fuel is allowed to escape without pressure via the leakage overflow bore (7). The leakage chamberis sealed toward the outside by the O-rings (3).This prevents leaking fuel from escaping.The union is confirmed as being SOLAS-compliant by DNV and GL.
