Under the Washington Industrial Health and Safety Act, the Department of Labor and Industries (L&I) adopts rules and regulations of safety and health standards governing the conditions of employment in all work places. L&I sets occupational health and safety standards that are at least as effective as the federal standards.
Current rules and regulations provide safety standards for the operation, maintenance, and construction of electric power generation, control, transformation, transmission, and distribution of electrical lines and equipment, as well as line-clearance tree-trimming. Among other requirements, persons trained in first aid and cardiopulmonary resuscitation must be available when employees are performing work on or associated with exposed lines or equipment energized at 50 volts or more.
An automated external defibrillator (AED) is a medical device used in the event of a sudden cardiac arrest that analyzes the heart rhythm and delivers an electrical shock to re-establish an effective heart rhythm.
Employers with employees who operate, maintain, or construct high voltage lines and equipment or who conduct line-clearance tree trimming in close proximity to high voltage lines and equipment must:
To be considered proficient, an employee must have completed initial or updated training within the previous two years.
High voltage lines or equipment means any energized communication line, electric supply line, or equipment with a voltage of 601 or greater.
