Safety
Hazards during operation and
maintenance
Hazards due to noise
The development of noise during operation is influenced by the installation
and operating conditions. Noise with a sound pressure level exceeding
85 dB(A) is harmful.
Hazards due to noise
Noise can cause impaired hearing, damage to health, mental disturb-
ances, diminished attention and irritation.
Always wear ear protection when the engine is running.

When the sound pressure level is above 85 dB(A), always wear ear

protection.
Wear ear protection.
Hazards due to hot surfaces and substances
During operation, turbocharger surfaces and attached parts as well as op-
erating materials (lubricating oil) become hot. The surface temperature is
dependent on the effectiveness of the insulation being used. The tem-
perature can become high enough so that it falls into ranges where burns
are possible.
Risk of burning
Touching hot surfaces or contact with hot operating materials can lead
to serious burns.
Do not touch hot surfaces and heed the warning plate on the turbo-

charger.
Wear heat-resistant safety gloves and protective clothing.

Allow the turbocharger to cool down before carrying out any work.

Wear safety gloves against thermal risks.
Hot surfaces on uninsulated turbochargers
Uninsulated turbochargers can cause serious personal injuries (burns).
The turbocharger is supplied by ABB Turbo Systems without insulation
depending on the order from the engine builder. In this case, the engine
builder is responsible for insulating the turbocharger properly or for
providing protection against hot surfaces being touched.
The engine builder's instructions and specifications about protection

against hot turbocharger surfaces must be observed in every case.
