Section three was revealed in 2008. It developed and tested a methodology for analyzing the prices and benefits of particular undergrounding proposals. The methodology has two components: a standard weather evaluation and a hurricane assessment. The model used in the normal weather evaluation includes the basic cost of utility capital and operations. It additionally includes reliability information that permits for the calculation of buyer interruption charges and interruption-related costs. The hurricane mannequin determines infrastructure injury and related prices related to tropical storms of hurricane energy that make landfall in Florida.

More than half of the electrocutions of electrical staff have been caused by direct (from energy supply) or indirect contact with dwell electrical equipment and wiring (together with gentle fixtures, circuit breakers, control panels, junction packing containers, and transformers) (McCann, Hunting et al. 2003, Janicak 2008). Many of those violations are associated to the usage of temporary power during building and renovation (Wheeler 2016). The Nationwide Electrical Contractors Affiliation (NECA) has developed a consensus commonplace on this topic. The standard addresses the best way to conduct proper planning and keep away from frequent OSHA violations associated to planning, use of receptacles, and temporary lighting amongst different topics (NECA 2016). For non-electrical workers, the principle trigger of electrocution was contact with overhead or underground energy traces. These deaths were the results of failure to de-energize or protect the power lines and failure to keep up minimum clearance distances from energy strains. Lastly, another frequent cause of electrocution is the improper use or care of extension cords.
