lubricants, auxiliary materials, special instructions for

applications with gaseous fuel

Natural gas

Observe the safety data sheet.

Caution: Highly flammable gas, forms an explosive mixture with air/oxygen.

Caution: Weak narcotic gas, risk of suffocation at very high concentration.

All gas-carrying lines must be checked for leaks prior to commissioning and at regular intervals during opera-

tion.

Procedure in the case of accidental release of gaseous fuel:

• If safely feasible: Shut off main gas supply.

• If safely feasible: Carry out emergency stop.

• Cordon off danger zone.

• Ensure sufficient ventilation!

• Do not enter danger zone before measurements with a suitable gas detector have confirmed that gas con-

centration is not hazardous.

Biogenic gases from fermentation processes

Observe the safety data sheet.

Caution: Highly flammable gas, forms an explosive mixture with air/oxygen.

Caution: Can be life threatening depending on concentration. Some gases can no longer be detected by

sense of smell in higher concentrations.

Caution: Risk of poisoning due to hazardous byproducts. The absorption of even small quantities of hydrogen

sulfide or ammonium may be lethal.

Caution: Danger of suffocation. Due to the lack of oxygen, the absorption of methane can occasionally lead

to increased breathing frequency (hyperventilation) and heart rates, low blood pressure, numbness of the ex-

tremities, drowsiness, mental confusion and loss of memory!

Biogenic gases tend to segregate. In low-lying areas of the plant, carbon dioxide enrichment is possible.
