What hazard is commonly associated with battery work in the engine compartment?

Explanation:
Battery work in the engine compartment can release hydrogen gas. Lead-acid batteries produce hydrogen during charging and when electrical connections are disturbed, and in a confined engine bay this gas can accumulate. Hydrogen is colorless, odorless, and highly explosive if ignited by sparks or flames, making an explosion the primary hazard to watch for. To reduce risk, work in a well-ventilated area with ignition sources kept away and handle cables carefully, especially when disconnecting or reconnecting the battery.
