Although at first glance both kits may contain similar things, these kits have different main purposes.
An emergency evacuation kit is necessary for every person and will provide you with peace of mind and self-sufficiency for a short period of time. Usually this kit is needed in case of sudden emergencies or emergencies and immediate evacuations, in which you do not have time to pack your luggage or take necessary things with you, but you need to grab a pre-prepared bag (comfortable backpack) and urgently leave your home, institution or place of residence.
The things in the kit should provide you with food, water, warmth and security for a short time, for which it is possible to be evacuated for, for example, 2-3 days. Such situations may be large fires, floods, earthquakes, civil unrest, military actions, etc.
A survival kit has a slightly different purpose. It is designed to be self-sufficient and to survive with it for a longer time outside the place where you live. It can provide you with food, water, warmth, survival in nature between one week and one or more months. These kits have tools and gadgets for fishing, cooking in the forest, making a shelter, etc. It can also be used in cases of emergency evacuation, but also contains many other useful things (tools) for survival. These kits are also suitable for hunters, fishermen, mountaineers, tourists, for people prone to extreme experiences, etc.
