housing/shelter, energy (not immediate) and health needs (not immediate in a healthy population). The prior list is not exhaustive. Longer term needs might include communications/transport needs in a developed population. This list of needs is associated with mission critical personnel in a clear manner - food production requires farmers, food distribution requires transportation personnel, water requires water-infrastructure maintenance personnel (a long term requirement if existing water infrastructure has been maintained to a high standard), clothing tends to require individuals to maintain clothes production infrastructure, similarly for sanitation. In emergencies, housing/shelter requires someone to build the shelter and maintain it over the long term if necessary. Health needs are met by doctors, nurses and surgeons. Implicit use of infrastructure requires personnel to maintain that infrastructure also - so food transportation requires not only that there are drivers for food trucks, but also that (over the long term) there are highways maintenance personnel who can maintain the roads, traffic infrastructure and signs for the roads, this in turn requires power supply personnel to provide power for traffic lights, etc...

An example of a safety critical system is a chemical manufacturing plant control system.
