OSHA's Process Safety Management (PSM) standard (29 CFR 1910.119) aims to prevent catastrophic releases of highly hazardous chemicals. It applies to processes involving these chemicals at or above specific threshold quantities. Effective PSM is built upon 14 interdependent elements, forming a comprehensive framework for managing risks and ensuring workplace safety.

Enforcement data consistently shows that certain PSM elements are frequently cited, indicating systemic weaknesses. These "top offenders" often result in significant penalties and highlight critical areas for improvement in process safety programs.

The "Big Four" – Process Safety Information, Mechanical Integrity, Operating Procedures, and Process Hazard Analysis – are foundational. Deficiencies in these areas can undermine the entire safety system and are often associated with the most significant penalties.

OSHA's PSM and EPA's Risk Management Program (RMP) share the goal of preventing chemical accidents. PSM focuses on worker safety inside the facility, while RMP targets public health and the environment outside. However, their prevention program requirements significantly overlap.
Worker safety within facility boundaries.
Public health and environmental protection outside facility boundaries.
Key Overlapping Elements:
Deficiencies in one program often indicate systemic weaknesses impacting the other. An integrated approach to chemical safety management is more efficient and effective for robust overall safety outcomes.
A critical insight, particularly emphasized by the Chemical Safety Board (CSB), is that OSHA's PSM standard does not explicitly require Management of Change (MOC) for organizational changes. This includes modifications like budget cuts, staffing level reductions, or company reorganizations, which can significantly impact process safety.
CSB Finding: This gap was identified as a contributing factor in major incidents, such as the BP Texas City disaster, where budget and staff reductions impaired process safety.
The CSB's recommendation to OSHA to address this remains "Open – Unacceptable Response," indicating a known, unaddressed systemic vulnerability at the regulatory level.
While not currently mandated, companies should proactively consider extending MOC principles to cover significant organizational changes to prevent unforeseen safety consequences and manage risks comprehensively.
The analysis of PSM compliance data reveals consistent challenges in foundational areas. An integrated, proactive approach is essential for improving safety outcomes. Based on the report, key recommendations include:
