What explosive gas is generated during the charging process of an electric stacker?

During the charging process of an electric stacker, hydrogen gas is generated as a byproduct of the electrochemical reaction occurring within the batteries. Most electric stackers use lead-acid batteries, and when these batteries are charged, the chemical reaction involves the reduction of lead dioxide and the oxidation of sponge lead, resulting in the production of hydrogen gas at the negative electrode.

Hydrogen is particularly significant because it is highly flammable and can pose an explosion risk if not properly managed. Adequate ventilation is crucial in areas where charging occurs to prevent the accumulation of hydrogen gas. This is why safety guidelines for forklift operation emphasize awareness of gas production during charging to mitigate potential hazards to operators and the surrounding environment. The other gases listed, such as oxygen, nitrogen, and carbon dioxide, do not have the same relevance in this context.
