Chain of Survival

Safety to life does not depend solely on any single safeguard.

The chain of survival illustration demonstrates how safety to life does not depend on any single safeguard — they must all work together within a layered fire protection plan in order to save lives and protect property.

According to the NFPA, a successful layered fire protection plan should be designed so that reliance for safety to life does not depend solely on any single safeguard. Additional safeguards shall be provided for life safety in case any single safeguard is ineffective due to inappropriate human actions or system failure.
