Field Review of Permits - Strategies & Effective Practices to Manage and Mitigate Hazards

Last updated February 19, 2021 | Element: Strategies & Effective Practices to Manage and Mitigate Hazards

Conducting initial field inspection

  • Ensure that the equipment that will be worked on is identified/tagged prior to issuing the SWP. 
  • Confirm that the location is safe and does not require additional measures to control hazards. 
    • Safe access is available for the work crew 
    • Area is safe to move objects required for execution of the job 
    • Escape routes are clear 
  • Identify the requirements for decommissioning procedures, blinding diagrams, and isolation lists. 
  • Confirm that there are no routine or non-routine vents present in the area that could impact the work crew.
  • Confirm that there are no leaks or abnormal situations noticed in the vicinity of the work location. 
  • Checklists for all related SWPs such as Excavation, Hot Work, Work at Height, and Confined Space Entry, are available and completed, including signatures/initials. 

Conducting field inspection prior to authorizing the permit

  • Ensure that the controls that are listed in the permit, task risk assessment, Job Safety Analysis (JSA), procedures, blinding diagrams or in checklists are executed as intended. 
  • Confirm that all energy isolations are completed, verified, and keys for the lock out are available with the work crew. 
  • Verify that there are no additional hazards (spills, leaks) present at the time of field inspection than the hazards for which controls are in place.
  • Ensure that the number of persons in the area that could be impacted are minimized and are consistent with the number considered in the risk assessment. 
  • Confirm that there are no simultaneous operations (SIMOPS) planned around the job location during execution of the Safe Work Permit. 
  • Verify that all tools, material, fire and gas detectors, communication tools and personnel protective equipment (PPE) required for safe execution of the jobs are available and meet the required specifications. 
  • Ensure that the work crew has been briefed and understood the hazards and controls. 
  • Verify that the work crew is competent and has all the necessary skills to perform the job safely. 
  • Verify that the frequency of field reviews during execution of the job has been established.  
  • Ensure that any outside contract crews working in the area who are not associated with the permit in question are informed of the work to be done. 

Conducting field inspection during execution of Safe Work Permit

  • Field inspections are carried out by the Permit Issuer in the presence of the Permit Receiver (Acceptor) at the frequency specified in the SWP. 
  • Ensure area is safe and permits are extended by authorized permit roles 
  • Ensure that no additional hazards exist beyond those being managed by the permit. 
  • Ensure that the work crew is available, is not fatigued and they have all equipment and personnel protective equipment (PPE) necessary to complete the work safely, even in adverse ambient conditions. 
  •  Ensure that the work crew is taking breaks as specified in the risk assessment 
  •  Verify that all necessary and relevant checklists are being filled and records maintained. 
  • Ensure actions are taken to promptly correct any problems or deficiencies observed in this inspection. 

Conducting field inspection after completion of execution of Safe Work Permit

  • Verify that the work has been executed to the relevant engineering standards and satisfies the requirements of those standards.   
  • In addition, ensure that:  
    • The work site is restored, and all tools and temporary equipment have been packed up. 
    • Combustible materials, molten metal pieces after gas cutting, hot welding rods, hot surfaces after welding, and metal cuttings have been allowed to cool safely and are then removed. 
    • All electrical work is per codes and requirements.  Ensure that temporary electrical junction boxes or extension boards with live electric supply have been de-energized and removed.  
    • Contaminated hoses used for decommissioning have been decontaminated and moved to a safe location. 
    • Uncontaminated/unlabeled equipment is removed from job location. 
    • Area housekeeping is adequate for safe re-start of equipment. 



Structured field review checklist

  • Gather data to develop metrics or key performance indicators (KPIs) to inform management of strengths and weaknesses in the system and to provide recommendations for where to place resources to improve the process.
