Process Hazard Analysis

process safetyWhy Is a Process Hazard Analysis Necessary?

In 1992, OSHA issued the PSM mandate (1910.119). This mandate requires employers to perform a process hazard analysis (PHA) of each PSM-covered process. The PHA shall be appropriate to the complexity of the process and shall identify, evaluate, and control the hazards involved in the process.

Cognascents facilitators and engineers are available to help companies comply with PHA requirements of 1910.119 and 40 CFR 68.

Why Is a Risk Assessment Needed?

The Clean Air Act Amendment of 1990, Section 112(r), required the EPA to issue regulations and guidance to prevent accidents and releases at facilities producing, handling, processing, distributing, or storing certain chemicals. The Chemical Accident Prevention Provisions of Section 112(r) require these facilities to develop, implement and sustain a risk management plan (RMP).

Each facility’s program should address risk assessments that detail the potential effects of an accidental release, an accident history of the last five years, and an evaluation of the worst-case and alternative accidental releases. Subparts A, B, C and D of Title 40 Chapter I Subchapter C Part 68 provide guidance regarding risk assessment requirements of the RMP rule.
