🔍 Key Concepts

• Battery terminal safety and what happens if metal objects bridge the terminals • Difference between electrical hazards (short circuits) and chemical hazards (electrolyte and gas) • How explosive gases from batteries are normally controlled (e.g., ventilation, not physical covers)

💭 Think About

• Think about what could happen if a metal tool or loose object falls across the top of an uncovered battery: what is the immediate danger? • Which of the answer choices describes something that a simple solid cover on top can directly prevent, without needing ventilation or securing straps? • Ask yourself: covers sit directly over the posts and wiring—what specific risk at that location are they mainly addressing?

✅ Before You Answer

• Identify which answer choices deal with electrical contact at the terminals versus general battery safety issues • Consider how explosive gases are removed (usually by ventilation) rather than blocked in by a cover • Check which choice matches a hazard that occurs right at the top of the battery, where a cover would be installed
