Permit to Work

Permit To Work

Permit To Work (PTW) is a formal communication system for risk identification, management & control, and communication. PTW systems are used in hazardous industries to request, review, authorize, document and most importantly deconflict tasks to be carried out by front line workers.

PTW is a core element in integrating safe industrial systems, including Risk Assessment and Isolation Planning. Integrated safety systems enable As Low As Reasonably Practicable (ALARP) reduction of unsafe activities in non-trivial work environments. PTW adherence is essential to achieve Process Safety Management.

Permit to Work is a module of Yokogawa's fully integrated Operations Management System.

Customer Challenge

Challenges that Come with the Paper Based Permit-To-Work Systems

  • Geographically distributed: Hard for all teams to be aware of pending and current permits.
  • Ability to reference other permits: Ensuring all staff are aware of related work that may impact team safety
  • Auditability: OHS staff must manually review all paper based documentation
  • Assurance of permit consistency: Automatic field validation
  • Permit and tag writing effort: Manually completing multiple copies of documentation for respective teams
