Lead-Acid Battery Safety Guide
The electrolyte''s chemical reaction between the lead plates produces hydrogen and oxygen gases when charging a lead-acid battery. In a vented lead-acid battery, these gases escape the lead-acid battery case and relieve excessive pressure. But when there''s no vent, these gasses build up and concentrate in the lead-acid battery case.

Lead
Lead exposure can occur not only in the production of these kinds of objects but also in their use (e.g., firing ranges), repair (e.g., radiator repair), and recycling (e.g., lead-acid battery recycling). In the general population, lead may be present in small but hazardous concentrations in food, water, and air.
Dispose of Hazardous Waste
Aerosols/Propane Gas Cylinders. Never recycle or dispose of aerosol cans or propane gas cylinders unless they are empty. Many household recycling opportunities accept empty aerosol cans. If the product is non-toxic, the remaining aerosol can contents can be discharged into a box (or onto trash) outside and away from ignition sources, children ...
Battery Gassing
Battery Gassing. The gases given off by a lead-acid storage battery on charge are due to the electrolytic breakdown (electrolysis) of water in the electrolyte to produce hydrogen and oxygen. Gaseous hydrogen is produced at the negative plate, while oxygen is produced at the positive. Hydrogen is the gas which is potentially problematic.
