To prevent explosive gas accumulation from energy storage devices, which measures are recommended?

• A. Diffusion only
• B. Ventilation only
• C. Both Diffusion and Ventilation
• D. Neither Diffusion nor Ventilation

Answer: (C)

Preventing explosive gas buildup from energy storage devices relies on two complementary approaches: diffusion and ventilation. Diffusion helps disperse gas that is emitted from the device, spreading it through the surrounding space which can help dilute concentrated pockets, but it’s slow and can leave areas with higher concentrations if the space is not well designed. Ventilation actively exchanges the room air, carrying away any accumulating gas and replacing it with fresh air, which significantly lowers the overall gas concentration and keeps it well below the lower explosive limit. Using both ensures gas is both distributed and removed efficiently, providing a robust safeguard against buildup. Relying on diffusion alone can allow dangerous pockets to form, while ventilation alone might be overwhelmed if emission continues; together they address both dispersion and removal for safer operation.
