Who Will Benefit
Anyone whose job involves designing, reviewing, evaluating or installing fire protection systems, including: designers, installers, engineers, electrical contractors, technicians, project managers, fire marshals, and architects.
- NEC Chapter 5 addresses occupancies that require special considerations, including requirements for hazardous (classified) areas, special or unusual hazards and unusual aspects of ordinary wiring systems.
- In the NEC classification system, Classes I, II and III are assigned to areas based on the presence of various types of hazardous material. Division and Zone designations for areas are based on the likelihood that classified material is present in an ignitable form.
- The NEC classification system in Chapter 5 includes specific requirements for certain common applications, including commercial garages, aircraft hangars, motor fuel dispensing facilities, bulk storage plants and spray application, dipping and coating processes.
- Requirements for healthcare occupancies recognize that people in patient care areas may be electrically compromised due to direct contact with metallic equipment or intravenous lines and probes inserted under the skin. Patient care areas have special grounding requirements, and some types of healthcare facilities require an "essential electrical system."
- Chapter 5 also provides special requirements for other occupancies, including areas of assembly, theaters and similar locations, temporary and permanent amusement attractions, motion picture and television studios, film projection rooms, manufactured buildings, agricultural buildings, mobile homes, manufactured homes, recreational vehicles and park trailers, floating buildings, marinas and boatyards and temporary installations.
