Technical documents belonging to process safety information shall be clearly marked with a unique identifier for easy identification. The technical documents belonging to the process safety information are uniformly indexed and indicate the place of storage, the person responsible, the latest revision date or the version number. Catalog indexing and process safety technical documentation are archived in electronic or paper form. It is important to ensure that all employees who are exposed to hazardous materials, including contractor employees, have easy access to process safety information. Process safety information is periodically updated as required by Change Management (MOC) to prevent misuse of expired or expired versions of the file. The primary use of process safety information is to perform process hazard analysis ( PHA ) on the process, and the analytical work group must verify process safety information each time before the process hazard analysis. A summary of the revisions from the previous edition is required in the process safety information of the new revision. The complete process safety information file retains at least one redundant backup and is stored in a secure location. Establish control procedures to prevent documents (text or electronic) from being lost, tampered with, or improperly transmitted. Process production, operation, maintenance, and management personnel should be trained using process safety information. Process safety information files are generally reviewed once a year, and audit opinions are submitted for the results of the audit. Audit records and audit conclusions should be filed and managed.
