The objective of a process safety management system (PSMS) is to ensure potential hazards are identified and that mitigation measures put in place to prevent the unwanted release of energy or materials into locations that could expose employees to serious harm.
An effective PSMS requires a systematic, comprehensive management program that integrates technologies, procedures, and management practices to evaluate the whole chemical process. Process design, process technology, process changes, operational and maintenance procedures, non-routine activities and procedures, emergency preparedness plans and procedures, training programs, and other elements that affect the process are all considered.
A PSMS focuses on process safety, while an SMS includes all aspects of safety including occupational safety.
The SMS or PSMS framework describes the different elements implemented to ensure safety at a facility. Each element incorporates the underlying principles and expectations to be met across all areas of the business or operation.
The total system for managing safety typically comprises three distinct levels of application and implementation.
- Level one (SMS/ PSMS framework) provides an overview of how the PSMS is structured and implemented as well as the achievement standards and expectations by which the company behaviour and standards are driven.
- Level two documents provide guidance to translate those standards and expectations into practical application at the work fronts.
- Level three are the specific procedures, plans, checklists, and forms for use in each operational area.
The elements of an SMS or PSMS are typically customised for a particular company, however, these are often influenced by national guidance/ legislation or international standards such as ISO, Energy Institute, or CCPS. Common elements would include hazard identification and risk assessment management, management of change, emergency preparedness, incident investigation, monitoring, and auditing, etc.
Safety Solutions has developed the level 1 PSMS/ SMS framework documents as detailed in section 3 and has prepared level 2 procedures such as emergency preparedness, hazard and risk procedures, incident investigation, management of change processes.
