The provisions of the IWUCl apply to the construction, alteration, movement, repair, maintenance and use of any building, structure or premises within the wildland urban-interface areas in this jurisdiction. Buildings or conditions in existence at the time of the adoption of this code are allowed to have their use or occupancy continued, if such condition, use or occupancy was legal at the time of the adoption of this code, provided such continued use does not constitute a distinct danger to life or property.

The guide discusses various battery systems so that the user can make informed decisions on selection, installation design, installation, maintenance, and testing of stationary standby batteries used in UPS systems.

This Code covers basic provisions for safeguarding of persons from hazards arising from the installation, operation, or maintenance of conductors and equipment in electric supply stations and overhead and underground electric supply and communication lines. It also includes work rules for the construction, maintenance, and operation of electric supply and communication lines and equipment. The standard is applicable to the systems and equipment operated by utilities, or similar systems and equipment, of an industrial establishment or complex under the control of qualified persons.

The standard helps ensure effective fire control, extinguishment, prevention, or exposure protection through requirements for the design, installation, and system acceptance testing of water spray fixed systems for fire protection. It also contains requirements for the periodic testing and maintenance of ultra high-speed water spray fixed systems.

NFPA 70E requirements for safe work practices to protect personnel by reducing exposure to major electrical hazards. Originally developed at Occupational Safety and Health Administration (OSHA)’s request, NFPA 70E helps companies and employees avoid workplace injuries and fatalities due to shock, electrocution, arc flash and arc blast, and assists in complying with OSHA 1910 Subpart S and OSHA 1926 Subpart K.

NFPA 400 consolidates fundamental safeguards for the storage, use, and handling of hazardous materials in all occupancies and facilities. The Code does not apply to storage or use of hazardous materials for individual use on the premises of one- and two-family dwellings.

The guide describes the structure, application and limitations of the Fire Safety Concepts Tree, which provides an overall structure with which to analyze the potential impact of fire safety strategies. NFPA 550 examines the interrelation of fire safety features and their effect on achieving specific fire safety goals and objectives.

The standard provides criteria for assessing the health, flammability instability and related hazards presented by short-term, acute exposure to a material under conditions of fire, spill or similar emergencies. A number rating system of 0-4 is provided to rate each of the four hazards on a placard and provides emergency responders with information to determine immediate actions in an emergency. Tables in the standard provide criteria for the ratings and placard specifications such as letter size and arrangement of numbers and colors.

The document provides fire prevention and fire protection recommendations for hydroelectric generating plants to safeguard personnel, protect physical property, ensure continuity of power production, and control the impact of fire and firefighting activities on the environment. NFPA 851 offers guidance for the design, construction, and operation of hydroelectric facilities. In addition, general plant design, fire protection systems, identification and protection of hazards, and development of a fire risk control program are also covered.

"The standard applies to the classification of degrees of protection provided by enclosures for electrical equipment with a rated voltage not exceeding 72,5 kV. The object of the standard is to give a) Definitions for degrees of protection provided by enclosures of electrical equipment as regards: 1) protection of persons against access to hazardous parts inside the enclosure; 2) protection of the equipment inside the enclosure against ingress of solid foreign objects; 3) protection of the equipment inside the enclosure against harmful effects due to the ingress of water.
