🔍 Key Concepts

• Gas behavior in enclosed spaces (lighter-than-air vs heavier-than-air) • Hazards of hydrogen gas produced during battery charging • Purpose and best placement of exhaust ventilation in small rooms

💭 Think About

• When batteries are charging, what gas can be produced and is it lighter or heavier than air? • If a gas tends to rise, where in a room will its concentration be greatest without ventilation? • Which exhaust location would most effectively remove that gas before it accumulates into an explosive mixture?

✅ Before You Answer

• Identify whether hydrogen from charging batteries rises or sinks in air • Consider where a flammable gas layer would form first in a still air battery room • Match the exhaust location that best removes the highest concentration zone of the gas
