PRACTICE STATEMENT:

To eliminate injuries to personnel from improper job planning and risk assessment.

PRACTICE DESCRIPTION:

Identify protection methods and risk mitigation techniques based on information obtained through information transfer and jobsite analysis.  The information obtained through this process shall be provided to the employee in charge to supplement the field crew’s job briefing.

1. Pre-planning to begin at the pre-bid meeting.
2. Preliminary job site analysis.
3. The Contractor shall request information from the Host Employer so that the Contractor may be able to conduct adequate risk assessments prior to beginning and during operations.  As a minimum this information shall include:
   • Nominal voltage of lines & equipment
   • Maximum switching transient voltage (TOV)
   • Presence of induced voltage
   • Presence of protective grounds and grounding conductors
   • Location of circuits and equipment, including electric supply lines, communication lines, and fire protective signaling circuits
   • The condition of protective grounds and equipment grounding conductors
   • The condition of structures, poles, and/or other facilities.  
   • Environmental conditions related to safety
   • Other known system information related to safety, requested by the contractor such as incident energy, MAD distance, AR clothing.
4. Knowledge of any change in the original work task and any other conditions or characteristics that may affect the safety of the workers.
5. Line work on conductors or equipment shall be performed when they are de-energized or a portion is de-energized and grounded when possible.
6. Information that is required of the contractor to be communicated to the host:
   • The contract employer shall advise the host employer of any unique hazardous conditions presented by the contract employer’s work. 
   • The contract employer shall advise the host employer of any unanticipated hazardous conditions found during the contract employer’s work that the host employer did not provide. 
7. Examples of Host Employer Communication may include work orders, job prints, bid documents, and/or one-line diagrams.  The contractor shall document communication (as stated in item “C” above) from the host employer.  

BENEFITS:

• Eliminate injuries resulting from improper planning by ensuring key job hazards are identified and controlled.
