Fire Protection NFPA 110, 1999 edition, Chapter 5-11.2
Where EPSS rooms or enclosures are equipped with fire protection systems, halon or carbon dioxide systems may not be used unless the engine combustion air is taken from outside. A ducting system would accomplish this.
Dry chemical systems cannot be used unless the EPS manufacturer certifies the chemical will not damage the equipment.
Where sprinkler systems are used, noncombustible hoods or shields must be installed to protect critical equipment.
Generators and automatic transfer switches as well as their appurtenant devices employ high voltages that can hurt you. Do not attempt to work with this equipment unless you are qualified. Observe all rules and cautions found in the manufacturer’s manuals as well as NFPA 70E, Standard for Electrical Safety in the Workplace.
