Keep all ignition sources out of hazard area. Only check injection nozzles in the nozzle testing device. Do not touch the injection nozzle stream. 

Potential risks 

Risk of explosion! 

Calibration fluid that escapes during the injection nozzle test is under high pressure and is very finely atomized. The calibration fluid mist hereby created is combustible and may trigger an explosion in combination with ignition sources, e.g. electrical sparks, cigarettes or open flames.

Risk of injury 

In the event of contact with the stream of the injection nozzle, this can penetrate deep into the skin and destroy the tissue. Diesel fuel or calibration fluid that enters the blood can lead to blood poisoning.
