CHBC UNIVERSITY / FIELD GUIDE

Process safety and occupational safety

Recognize overlapping safety disciplines and why one set of results cannot represent them all.

UNDERSTAND THE CONCEPT

Occupational safety addresses hazards that can harm people through their work. Process safety focuses on preventing major events involving hazardous processes, such as uncontrolled releases, fires, or explosions. The disciplines overlap, but their assurance questions are not identical. A plant can report few personal injuries while still having weaknesses in equipment integrity, operating information, or the management of process changes.

Enterprise reporting should therefore preserve the connection between major hazard scenarios and the controls intended to prevent them. Maintenance backlogs, unresolved technical findings, and changes awaiting review may matter alongside injury statistics. Measures need a clear technical basis and qualified interpretation. Neither a favorable injury rate nor a completed training dashboard proves that a hazardous process is adequately controlled. Local specialists determine the applicable process safety framework and site-approved procedures for the facility.

Questions to take back to your team

  1. Which major hazard scenarios need their own assurance measures?
  2. Can process-related concerns be seen separately from injury rates?
  3. Who reviews the technical meaning of those measures?
