The main safety functions shall be defined in a clear manner for each individual facility so that personnel safety is ensured and pollution is limited.
The following main safety functions shall be maintained in the event of an accident situation:
  1. preventing escalation of accident situations so that personnel outside the immediate fire area are not injured,
  2. the capacity of main load-bearing structures until the facility has been evacuated,
  3. protecting rooms of significance to combatting accidents so that they remain operative until the facility has been evacuated,
  4. protecting the facility's safe areas so that they remain intact until the facility has been evacuated,
  5. at least one escape route from every area where personnel are found until evacuation to the facility's safe areas and rescue of personnel have been completed.
Assessment of the consequences of loss of main safety functions after the facility has been evacuated shall also include serious harm to the environment and/or loss of major financial assets.
