BATTERY ROOM VENTILATION AND SAFETY . It is common knowledge that leadacid 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.

Ventilation rates should be sufficient to dilute hydrogen leaks to less than 25% of the LFL; which is about 1% by volume in air. Where passive ventilation is used, inlet openings should be located at floor level in exterior walls. Outlet openings should be located at the high point of the room in exterior walls or in the roof.

Typically, an exhaust fan installed in the production and compression building would run continuously during production to avoid a potential build-up of the combustible hydrogen gas. A differential pressure switch on an exhaust fan that indicates proper airflow can be used to inhibit the operation or the electrolyser and compressor ensuring safe working conditions.

By comparing single longitudinal and combined ventilation approaches, we derive the optimal strategy. Results reveal negligible combustion risk for slight leaks (≤0.6 g/s), with the top exhaust fan reducing combustible area by >99.5 %. Conversely, heavy leaks (>24 g/s) necessitate additional ventilation beyond top fan enhancement.

Learn MoreThe National Fire Protection Association lists the explosive concentration level, or Lower Explosive Level (LEL) of hydrogen as 4%, so the legislation stipulating a maximum level below 1% encourages the safe implementation of ventilation systems to avoid explosions far below the stipulated 4% explosive level.
Corrosion resistant fans with ATEX non sparking components, ideally roof mounted to exhaust upward and out are the ideal solution, but if not possible, ATEX wall mounted axial fans with back draught dampers, to avoid the return of hazardous substances, can be used.
When mixed with oxygen, Hydrogen is a highly explosive substance that is odourless, colourless and lighter than air. The lightweight element accumulates above the oxygen, and where effective ventilation is not in place, a build-up can occur.
