PSID: Process Safety Incident Database

Last updated November 9, 2021

The Center for Chemical Process Safety (CCPS) developed the Process Safety Incident Database to collect, track and share important process safety incidents and experiences among project participants.

The purpose of the CCPS Process Safety Incident Database (PSID) is to pool process safety incident experience among CCPS participating companies, for lessons learned from the experiences of others without suffering the consequences of failures.

PSID is a fully searchable incident database that is accessible on the web and includes more than 830 incidents. It can be accessed from any computer anywhere a secure web connection can be obtained. 

  • The New PSID is here!
  • The Steering Committee has been established!
  • The Legacy PSID will be remain in place for 3 months after the Roll Out of the new PSID.
  • The Legacy database has been used in CCPS for over 20 years
  • Get ready for the most significant improvement to PSID ever!

PSID is very versatile and contains valuable input for PHAs, incident investigations, lessons learned, and general process safety awareness. PSID is available to non-governmental and non-regulatory CCPS member companies for free.  Each member company has the authority to approve or deny/remove any of their employees’ access to the system. Please check with your CCPS TSC Representative or PSID Administrator to obtain access to the new database.
