02A.3 Natural gas
Natural gas is non-toxic and will not harm anyone breathing in the
low concentrations near minor fuel leaks. Heavy concentrations,
however, can cause drowsiness and eventual suffocation.
In a gas engine installation, gas may cause danger situations in
some cases. The most serious situations are caused by gas leaks into
the engine room, gas fires and gas explosions caused by unburned
gas in the exhaust system.
If a gas explosion occurs, it is important to protect people, equip-
ment and environment from damages. Damages are caused by
shock wave and burning effect of the expanding and partly burning
gases. Damages can be avoided by preventing pressure build up
in equipment and guiding the released pressure to an open area.
Read the Gas Safety Manual that can be found at the end of
chapter 03 for gas engine installations.
02A.4 Lubricating oils
Fresh lubricating oils normally present no particular toxic hazard, but
all lubricants should always be handled with great care. Used
lubricating oils may contain significant amounts of harmful metal
and PAH (polyaromatic hydrocarbons) compounds. Avoid pro-
longed or repetitive contact with the skin. Prevent any risk of splash-
ing and keep away from heat, ignition sources and oxidizing agents.
Risk of long term contamination of the soil and the ground water.
Take every appropriate measure to prevent water and soil contami-
nation.
