What safety measure should be followed when working on an engine?

• A. Always wear gloves and safety goggles.
• B. Always disconnect the battery and ensure the engine is cool.
• C. Always work with the engine running.
• D. Always allow the engine to warm up before servicing.

Answer: (B)

When working on an engine, disconnecting the battery and ensuring the engine is cool are critical safety measures that help prevent accidents and injuries. Disconnecting the battery reduces the risk of electrical shock and prevents accidental engine starts while maintenance or repairs are being performed. If the engine is still hot, there’s an increased risk of burns or injuries from hot surfaces, as well as potential hazards from fluids that may leak or become pressurized. These precautions create a safer working environment by mitigating the risks associated with electrical components and engine heat. Ensuring that the vehicle is in a safe state before beginning work is a fundamental practice for any technician. By following these steps, a technician can significantly reduce the likelihood of accidents and ensure a safer repair process.
