Final answer:
A survival kit should include non-perishable food and other essential items for sustaining life and safety during emergencies, such as a first aid kit, emergency shelter, basic tools, and means of communication.
Step-by-step explanation:
A survival kit with safety and emergency items should include non-perishable food as a fundamental component. This type of food is essential for survival situations because it has a long shelf life and does not require refrigeration. A survival kit should be equipped with items that can aid in sustaining life and safety during emergencies. For a family of four, the basic necessities in a survival kit can include a reliable water supply, a first aid kit, emergency shelter, and ways to communicate, such as a hand-crank or battery-powered radio. Moreover, additional supplies might include a flashlight with extra batteries, an emergency whistle, matches or a lighter, and basic tools for repairs.
