1.4 Fuel and Fumes Are Flammable
Fire, explosion, and personal injury or death can result from improper practices.
• Do not fill fuel tanks while the engine is running unless the tanks are outside
the engine compartment. Fuel contact with hot engine or exhaust is a potential
fire hazard.
• Do not permit any flame, cigarette, pilot light, spark, arcing equipment, or other
ignition source near the generator set or fuel tank.
• Fuel lines must be adequately secured and free of leaks. Fuel connection at the
engine should be made with an approved flexible line. Do not use copper piping
on flexible lines as copper will become brittle if continuously vibrated or
repeatedly bent.
• Make sure all fuel supplies have a positive shutoff valve.
• Make sure the battery area has been well-ventilated prior to servicing near it.
Lead-acid batteries emit a highly explosive hydrogen gas that can be ignited by
arcing, sparking, smoking, etc.
1.5 Starting Batteries
WARNING
Toxic Hazard
The electrolyte in starting batteries is a dilute sulfuric acid that is harmful to
the skin and eyes. It is also electrically conductive and corrosive.
Always:
1. Wear full eye protection and protective clothing;
2. If the electrolyte contacts the skin, wash it off immediately with water;
3. If the electrolyte contacts the eyes, flush them thoroughly and
immediately with water and seek medical attention; and
4. Wash spilled electrolyte down with an acid neutralizing agent. A
common practice is to use a solution of one pound (500 grams)
bicarbonate of soda (also known as baking soda or sodium bicarbonate)
to one gallon (4 liters) of water.
5. Continue to add the bicarbonate of soda solution until the evidence of
reaction (that is, foaming) has stopped.
6. Flush the resulting liquid with water and dry the area.
1.6 Batteries Can Explode
Batteries can explode, causing severe skin and eye burns and can release toxic
electrolytes.
