This report is a comprehensive study of the causes and prevention of hydrogen gas accumulation in electric lighted buoys powered by lead-acid storage batteries. The chemistry of possible causes of hydrogen evolution is discussed. Measurements of hydrogen concentration in various lighted buoys are presented. Results showed a high percentage of buoys with explosive mixtures in battery pockets. Increasing the size of ventilation tubing and converting to an open type vent valve reduced the hydrogen gas concentration below the lower explosive limit.
