What is Gap Analysis?

Gap analysis is a systematic process used to evaluate an organization’s existing programs, procedures, and controls against applicable regulatory requirements, industry standards, or best practices. The objective is to identify discrepancies, referred to as “gaps”, between current practices and those required for compliance, risk reduction, and optimal performance.

By determining these gaps, organizations can prioritize corrective actions, allocate resources effectively, and develop targeted improvement plans that strengthen safety and operational resilience.

In high-hazard industries, gap analysis is a proactive tool commonly used to assess the strength and effectiveness of safety management systems. It supports continuous improvement by helping facilities meet regulatory expectations, reduce risk exposure, and prevent incidents before they occur.

Gap Analysis for Process Safety Management and Combustible Dust Programs

Sigma-HSE offers two specialized gap analysis services to evaluate compliance gaps and assess management program effectiveness.

Our Combustible Dust Gap Analysis, based on NFPA 652 and the consolidated NFPA 660, applies to facilities that handle, process, or generate combustible dusts or powders. This assessment evaluates dust hazard management programs by reviewing dust hazard identification, housekeeping practices, and engineering controls to determine alignment with NFPA standards and recognized and generally accepted good engineering practices (RAGAGEP).

Our Process Safety Management (PSM) Gap Analysis is designed for facilities that handle or process highly hazardous chemicals. This assessment benchmarks process safety programs against OSHA 29 CFR 1910.119 and relevant CCPS Guidelines for Risk-Based Process Safety, identifying deficiencies in process hazard analysis, operating procedures, training, mechanical integrity, and emergency response. The result is a clear, prioritized roadmap to close compliance gaps and reduce the risk of major chemical incidents.

For hybrid facilities subject to NFPA combustible dust and OSHA PSM standards, Sigma-HSE provides integrated gap analysis services that address overlapping and distinct requirements. This combined approach supports consistent risk management across combustible dust and chemical hazards, helping facilities streamline compliance efforts and strengthen overall process safety performance.

Our Approach to Gap Analysis for PSM or NPFA 652/660 Covered Facilities

Sigma-HSE conducts structured, standards-aligned gap analyses for facilities covered under NFPA 652: Standard on the Fundamentals of Combustible Dust, including the newly consolidated NFPA 660: Standard for Combustible Dusts and Particulate Solids, and/or OSHA Process Safety Management (29 CFR 1910.119).

Our approach is based on recognized methodologies, regulatory requirements, and RAGAGEP (Recognized and Generally Accepted Good Engineering Practices), delivering clear, practical insights to strengthen compliance and reduce risk.

Assessment of Current Safety Management Practices

Our process begins with a systematic evaluation of the facility’s existing programs, documentation, and operational practices. This assessment is tailored to the relevant regulatory framework:
