What items are typically found in an onboard emergency kit?

The correct choice includes first aid supplies, emergency tools, and medical equipment, which are essential components of an onboard emergency kit. Such kits are specifically designed to ensure the safety and health of passengers and crew during emergencies. First aid supplies allow flight attendants to respond promptly to injuries or medical issues, while emergency tools can assist in various situations, such as evacuations or addressing cabin issues. Medical equipment may include items like defibrillators or oxygen masks, which are crucial for addressing serious health emergencies on board.

The other options do not align with the purpose of an emergency kit. Electronic devices are typically not included, as their function does not pertain to immediate medical or emergency needs. Snacks and beverages are part of in-flight services but offer no assistance during emergencies. Comfort items for passengers, while important for overall passenger experience, do not address health and safety needs, which is the primary focus of an onboard emergency kit.
