It is common knowledge that lead-acid batteries release hydrogen gas that can be potentially explosive. The battery rooms must be adequately ventilated to prohibit the build-up of hydrogen gas. During normal operations, off gassing of the batteries is relatively small.
Most lead acid and NiCad batteries are now manufactured in enclosed containers with special plugs to permit ventilation without excessive loss of electrolyte. A typical battery room as built for the Channel Tunnel Main 132 kV/25 kV/21 kV Intake Substation at Folkestone, UK, is shown in Fig. 4.3.
Battery room cleanliness and ventilation are important because the battery chemistry for lead-acid storage batteries is sensitive to contaminants and temperatures above and below the manufacturer's rating. In addition, the batteries also release hydrogen (a potential fire hazard) to the battery room during charging.
