The design of safety signs for products has been influenced for many years by standards originally developed for accident prevention signs to be used in the general environment. As product safety signs evolved, some basic differences developed between their characteristics and those of environmental safety signs: Environmental safety signs are usually larger, observed at longer distances, and frequently contain lesser amounts of information for visual clarity at a distance. Product safety signs are likely to contain more information within a smaller format, are usually observed at closer distances, and must physically and visually integrate with a wide range of product size, shape, and color characteristics. Attempts by product manufacturers to address these variable characteristics have produced numerous approaches to the graphic treatment of such signs.
Throughout the United States and around the world, NFPA 70: National Electrical Code (NEC) sets the foundation for electrical safety in residential, commercial, and industrial occupancies. The 2017 edition of this trusted Code presents the latest comprehensive regulations for electrical wiring, overcurrent protection, grounding, and installation of equipment. Major additions reflect the continuing growth in renewable power technology. Other NEC revisions protect the public and workers from deadly hazards. Work with the latest requirements governing public and private buildings, homes, and structures; outdoor yards and lots; utility equipment; installations that connect to the power grid; and consumer-owned power generation systems and equipment. The 2017 NEC is better aligned with the safe work practices in NFPA 70E: Standard for Electrical Safety in the Workplace. (Softbound, 888 pp., 2017)

Photovoltaic Systems is a comprehensive guide to the design and installation of several types of residential and commercial PV systems. Numerous illustrations explain the concepts behind how PV arrays and other components operate, and photographs of actual installations show how components are integrated together to form complete systems.
NFPA 72 provides the latest safety provisions to meet society's changing fire detection, signaling, and emergency communications demands. In addition to the core focus on fire alarm systems, the Code includes requirements for mass notification systems used for weather emergencies; terrorist events; biological, chemical, and nuclear emergencies; and other threats.
Used correctly, the safe work practices in NFPA 70E can stop workplace electrical accidents before they happen by reducing exposure to major electrical hazards. Originally developed at 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. Each edition of NFPA 70E builds on the next, incorporating the latest research and "lessons learned" from the field.
