Other sources of risk must be identified before work, including live and adjacent live conductors (concealed in cavities, slabs or ground, overhead and underground), cramped conditions, confined spaces, multiple and stored supply sources (solar, wind, co-generation, batteries, UPS, inverters, capacitors), damp, heat, cold, vibration and noise, heights and falling objects, operational pressure to restore supply, unstable work areas, tensioned or unstable conductors, cables or equipment that could fall, nearby work and mobile plant, work below ground, corrosive or toxic materials, radiation from antennas and radar, asbestos, hazardous substances such as PCBs, conductive dust, failure to follow procedures, working alone, equipment design limits (for example switches not rated to break load) and the position of exposed live parts.
