INSPECTION AND TESTING OF EMERGENCY GENERATORS 
Certification requirements 
NFPA 101(00), Sec. 7.9.2.3 requires that emergency generators be installed, tested and maintained in 
accordance with NFPA 110, Standard for Emergency and Standby Power Systems. Chapter 2 of NFPA 
101 references the 1999 edition of NFPA 110.  
Buildings that fall under Chapter 18 of NFPA 101(00) and are equipped with or in which patients 
require the use of life-support systems (e.g. hospitals, nursing homes with residents on ventilators) 
must also meet the maintenance and testing provisions of the 1999 edition of NFPA 99, Standard for 
Health Care Facilities [see NFPA 101(00), Sections 18.2.9.2, 18.2.10.2, 18.5.1.2 and 18.5.1.3].  
Provisions dealing with maintenance and testing of emergency generators can be found in NFPA 
99(99), Sec. 3-4.4. This section starts out by referencing NFPA 110, but also deals with such issues 
as: 
• Testing intervals 
• Test conditions 
• Personnel qualifications 
• Maintenance and testing of circuitry  
• Maintenance of batteries 
Each facility should have a copy of these standards. They can be ordered from NFPA at 1-800-344-3555 or www.nfpacatalog.org. 

there is plenty on the web about this so excuses are in order.

Colin,

I gather these generators (that never generate) are commonly situated in basements below a potential flood level.  If not, how in the name of %$£& can a flood/storm stop them from running, as cited in the article? Are there totally separate circuits supplied by these generators, with appropriate safeguards, or does failure of the main supplies render them useless?  Are they tested regularly? Is their design/installation subject to mandatory regulation? Etc.

Hugh.
