Battery Safety

IMPORTANT SAFETY INSTRUCTIONS

The battery is a major component of the engine-generator set. The genset will not start without a properly maintained battery. Disconnecting the battery prevents the engine from starting. Always observe the following safety guidelines when interaction with the battery is necessary. Servicing of batteries should be performed by authorized personnel only.

1.Wear full eye protection and protective clothing, including rubber gloves and boots when handling a battery.

2.Remove watches, rings or other metal objects when handling a battery.

3.Use tools with insulated handles.

4.In case the battery liquid (dilute sulfuric acid) comes in contact with clothing or skin, rinse skin immediately with plenty of water and discard clothing.

5.In case the battery liquid (dilute sulfuric acid) comes in contact with your eyes, rinse eyes immediately with plenty of water for fifteen minutes, then contact the nearest doctor or hospital, and seek medical attention.

6.Spilled electrolyte is to be washed down with an acid neutralizing agent. A common practice is to use a solution of one pound (500 grams) bicarbonate of soda to one gallon (4 liters) of water. The bicarbonate of soda solution is to be added until the evidence of reaction (foaming) has ceased. The resulting liquid is to be flushed with water and the area dried.

7.DO NOT expose the battery to open flames, sparks, cigarettes etc. The battery contains combustible gases and liquids. If these

gases and liquids come in contact with a flame or spark, an explosion could occur.

8.DO NOT lay tools or metal parts on top of batteries.

9.DO NOT drop the battery; there is the risk the battery may explode.

10.ALWAYS discharge static electricity from the body before touching batteries by first touching a grounded metal surface.

11.ALWAYS keep the battery charged. If the battery is not charged a buildup of combustible gas will occur.

12.ALWAYS keep battery charging and booster cables in good working condition. Repair or replace all worn cables.

13.ALWAYS recharge the battery in an open air environment, to avoid risk of a dangerous concentration of combustible gases.

14.Only use a battery that is in proper working condition. Replace battery as recommended by manufacturer.

The battery contains electrolyte which is a dilute sulfuric acid that is harmful to the skin and eyes. Electrolyte is electrically conductive and very corrosive.

The installation of the engine-generator set must provide enough ventilation to ensure that gases generated by vented batteries during charging, or caused by equipment malfunction are removed. Lead-acid batteries present a risk of fire because they generate hydrogen gas.

If using a serviceable battery, never over fill the battery with water above the upper limit.

Always disconnect a battery charger from its AC source before disconnecting the battery cables. Failure to do so can result in voltage spikes high enough to damage the genset DC control circuits and charger.

Make certain the battery is well-ventilated before servicing. Arcing can ignite explosive hydrogen gas given off by batteries, causing severe personal injury. Arcing can occur when the cable is removed or reattached, or when negative (-) battery cable is connected and a tool used to connect or disconnect positive (+) battery cable touches the frame or other grounded metal that is part of the set. Always remove negative (-) cable first, and reconnect it last. Make certain hydrogen gas from the battery, engine fuel, and other explosive fumes are fully dissipated. This is especially important if the battery has been connected to a battery charger.

On generators not having a grounded supply circuit, determine if the battery is inadvertently grounded. When inadvertently grounded, remove source of ground. Contact with any part of a grounded battery is capable of resulting in electrical shock. The risk of such shock is reduced when such grounds are removed during installation and maintenance.
