What type of document must include a Record of Changes?

A Standard Operating Procedure (SOP) must include a Record of Changes to ensure that all revisions, updates, and modifications to the document are documented systematically. This practice is essential for maintaining the integrity and reliability of the SOP. The Record of Changes provides a clear history of amendments, allowing users to track what has been altered, when changes occurred, and who authorized them. This transparency is crucial for compliance, quality assurance, and accountability within processes involving hazardous materials.

While other documents such as QUAL/CERT records, training manuals, and safety checklists may undergo revisions, they do not typically require a comprehensive and formalized Record of Changes as part of their standard format. Instead, these documents might follow different procedures for updating or verifying their contents based on their specific purposes and regulatory requirements.
