Level 1 - systems where a failure of the equipment to perform could result in loss of human life or serious injury
Level 2 - systems where a failure of the equipment to peform is "less critical" to human life and safety.
My question is on the questionable, IMO, definition of Level 2; who is to define what is to be "less critical" to human life?
More importantly what does article 701, Legally required, coincide with. Are these systems Level 1 or Level 2.
If Level 2 implies some criticality to human life then I assume Standby systems are neither Level 1 or Level 2. Is that a true statement?
And if it is, NFPA 110 is entitled Emergency and Standby Power systems yet everything in it falls into one of two Levels neither of which appears to include Standby systems.
Can anyone clarify this for me?
Thanks,
Mike
