Construction has long been recognized as a high hazard industry and is one of the industries targeted in MOSH's Five Year Strategic Plan. Accidents relating to electrical hazards are one of the leading causes of serious injuries and fatalities. It is believed through a local emphasis program that increases awareness and accelerates enforcement activity, injuries can be reduced. It is also recognized that a tracking mechanism for these type inspections would prove beneficial in monitoring the area of electrical hazards. In the past, many un-programmed inspections have been conducted through CSHO self referrals, imminent danger complaints or through accident investigations. This LEP is designed to increase inspection activity, provide tracking, enhance expertise and formalize procedures.


MOSH compliance personnel shall ensure that the procedures contained in this Instruction are followed when conducting this LEP. The Regional Offices will implement the procedures described in this Instruction in response to imminent dangers or serious electrical hazards that are identified on construction sites. The Regional Supervisors shall use this LEP as a basis for scheduling and conducting safety inspections of construction sites. This LEP is intended to be used on any construction site where potential electrical hazards could exist and/or have been alleged to initiate safety inspections. These inspections shall be expanded to comprehensive inspections of multi-employer construction sites in accordance with the guidelines established in the FOM.


  1. An inspection targeting system which encompasses identification of sites at the beginning of the quarter and the random selection of sites is not practical. Electrical hazards on construction sites are normally transient and of limited duration. This limits the practicality of targeting the site in advance. Therefore, inspections conducted under this LEP would be initiated by several means: Compliance Officer observance, non-formal complaints, and referrals from other outside sources.
  2. All work sites where potential electrical hazards are observed by Compliance Officers will be selected for inspection under this LEP. Employee exposure to the electrical hazard does not have to be observed, only the presence of a potential electrical hazard needs to be observed to conduct an inspection. These sites shall include but shall not be limited to:
      1. Heavy Equipment and Crane Operations;
      2. Aerial Lifts
      3. Scaffold Usage
      4. Electric Utilities;
      5. Other activities which constitute potential electrocution hazards and no protective systems are in use such as electrical installation activities, excavation activities, and site clearing.
  3. When a jobsite with potential electrical hazards is noted during travel, the Compliance Officer shall notify the Supervisor with the name of the contractor (if known) and the location of the site. The Supervisor will determine if the site has been inspected within the last 30 days.
      1. If the site has not been inspected within the last 30 days, permission may be given to inspect the site. Compliance officers will record these inspections as planned inspections.
      2. If the site has been inspected within the last 30 days, an inspection will be authorized only if an imminent danger appears to be present or at the Regional Supervisor's discretion. These inspections will normally be limited to the imminent danger situation and other serious plain view hazards. The Compliance Officer will remain at the site to observe the abatement procedures and/or to recommend abatement methods. Compliance Officers will record these inspections as referral inspections.
  4. A large number of electrical hazards are reported via referrals and complaints, both of a formal and a non-formal nature. Formal complaints of electrical hazards on construction sites will continue to be scheduled before programmed inspections.
  5. The IMIS identifier code to be used in item 25c on the OSHA-1 or on the OIS equivalent form will be "ELECTROCUTION HAZARDS IN CONSTRUCTION".
