Question: When attaching manifold gauges to a running refrigeration system, which safety precaution is paramount?
Answer options:
- Always wear insulated gloves to prevent electrocution.
- Ensure hose connections are made quickly to minimize refrigerant loss. ✅ Wear appropriate personal protective equipment (PPE), including safety glasses and gloves.
