Lucent Technologies Enhanced VR Series Batteries
4 - 4 Safety and Environmental Issue 5 December 1998
A single battery is typically at low voltage; however, batteries
connected together in a system can pose a shock hazard in
addition to an energy hazard. When interconnection of the
batteries creates a hazardous voltage supply, post appropriate
warnings in the end systems or installations. All systems and/or
installations should consider the need for additional markings
based on the use of the battery, industry standards, and local,
state, and federal regulations.
Battery Gases
Valve-regulated batteries are designed to minimize the amount
of oxygen and hydrogen gas released from the battery under
normal conditions. However, abnormal conditions, such as high
temperature, abnormal charging, shorted cells, etc., can produce
greater amounts of gas. Even batteries under open circuit
conditions can produce gas. If not permitted to escape, this gas
can build up to explosive concentrations. Refer to Section 7,
Operation, for more information on gassing rates.
• ALWAYS place batteries in a well-ventilated area.
• NEVER place batteries in a sealed enclosure.
• Make sure the area is properly ventilated before performing
any work.
• Since gas generated by batteries is explosive, avoid creating
sparks (including those from static electricity), the use of an
open flame, or smoking near the batteries.
DANGER
RISK OF EXPLOSION
• Battery gases can be highly explosive. NO sparks,
including sparks generated by electrostatic discharge
(ESD), or open flame are allowed near battery modules.
Do not smoke around batteries. Make sure the battery
area is properly ventilated before performing any work.
• Do not place batteries in a sealed enclosure. Even
enclosures with ventilation need to be properly
evaluated to assure hydrogen will not accumulate to
explosive levels.
