Safety Precautions, continued

2.3.1

Sulfuric Acid Burns, continued

In case of eye contact with sulfuric acid, immediately:

Flush thoroughly every few minutes with large amounts of water.
Get medical attention.

If acid is spilled it should be neutralized with a solution of 1 pound of baking soda to 1
gallon of water (1 kg NaHCO

3

/ 10 l water) and then washed off with water.


2.3.2 Explosive Gases and Fire

Batteries generate explosive gases in all stages of operation. Under extreme
conditions these gases can explode, causing blindness and other serious personal
injury. Consider the following:

Always wear protective clothing and use the correct safety tools.
Eliminate any potential of sparks, fl ames or arcing.
Before working on the battery, be sure to discharge static electricity that can build
up on tools or the technician by touching a grounded surface in the vicinity of the
battery but far enough from the cells and fl ame arresters to avoid ignition of any
hydrogen gas present.
Provide adequate ventilation of the battery room.

In case of fi re:

If batteries are connected to a charger, shut off power.
Extinguish a fi re in a battery room containing lead acid batteries, using CO2,
foam, or dry chemical extinguishing media. Do NOT discharge the extinguisher
directly onto the battery. The resulting thermal shock may cause cracking of the
battery case/cover.
Leave the area as soon as possible if toxic fumes are present.
Wear breathing apparatus if it is required to remain in the area.

2.3.3 Electrical Shocks and Burns

Multi-cell battery systems can attain high voltage and/or currents, therefore, do not
touch un-insulated battery connectors or terminals. To prevent serious electrical
shock and burns, use extreme caution when working with the system.

Always wear protective clothing and use nonconductive or insulated tools when
working with any battery system.

Remove any jewelry or clothing that could produce a short circuit between the
positive and negative terminal of a battery or battery string.

Before working on the system:

Disconnect all loads and power sources to the battery.
If working on an assembled battery system, sectionalize (interrupt the battery
sections) into safe working voltage levels.
Check the battery system grounding. Grounding of the battery system is not
recommended. However, grounding of the rack is recommended.

Should you be required to work on a grounded battery system, make absolutely sure
you use the correct safety precautions, equipment and clothing.
