Which of the following is not a requirement for storage batteries?

• A. Batteries shall be located so that the equipment is adversely affected by battery gases
• B. Batteries shall be located in a ventilated area to limit gas buildup
• C. Batteries shall be located away from ignition sources
• D. Batteries shall be maintained in an accessible location

Answer: (A)

Storage batteries used in fire alarm systems can emit flammable hydrogen gas during charging, so safety focuses on preventing gas buildup, avoiding ignition sources, and keeping the batteries accessible for inspection and maintenance. Ventilation is required to limit gas accumulation, and keeping batteries away from ignition sources reduces the risk of a spark igniting any gas. They also need to be in an accessible location so service can be performed safely.

The option that describes locating batteries in a way that would allow gases to adversely affect nearby equipment is not a safety requirement; in fact, it’s exactly the kind of placement safety practices aim to avoid.
