    Process Safety Software: PHA, MOC, Barriers and Permits

    Content date: · Editorial responsibility: Dimitris Mitsios · No individual check logged· AI use

    Process safety software can organize hazard studies, change reviews, barriers and work authorization. Compare the specific applications required for your process, because a broad EHS suite or permit form does not establish specialist engineering calculations. This guide uses vendor documentation, not hands-on testing.

    What Is Process Safety Management?

    Process safety management addresses major hazards associated with industrial processes, including loss of containment. Software supports the people, procedures and engineering decisions needed to manage those hazards. It cannot substitute for those controls.

    OSHA's process safety standard sets requirements for covered processes. Check applicability and exceptions for your facility using the official standard. Map required evidence to change management, incident investigation, maintenance and training workflows before comparing products.

    Specialist Capabilities to Demonstrate

    Process Hazard Analysis

    HAZOP, What-If, FMEA, and Fault Tree Analysis studies with automated action tracking, revalidation scheduling, and scenario documentation.

    Bow-Tie & Barriers

    Visual bow-tie models linking threats, barriers, and consequences. Barrier health monitoring, degradation tracking, and critical control verification.

    SIS/SIL Requirements

    Distinguish target determination, quantitative verification and lifecycle records. Require evidence for the exact methods and calculation tools in the proposed application.

    Dates and Records OSHA 1910.119 Fixes

    Some PSM obligations run on fixed cycles, which makes them good demo tests: ask the vendor to show how each one is scheduled, who is reminded, and what evidence closes it. Paragraph references are to the current eCFR text of 29 CFR 1910.119.

    ElementWhat the standard setsAsk the vendor to show
    Process hazard analysis, (e)(6)Updated and revalidated at least every five years after the initial PHA, by a qualified teamRevalidation due dates per process, and recommendations tracked to resolution
    Training, (g)(2)Refresher training at least every three years, and more often if necessaryPer-employee refresher dates linked to the current operating procedures
    Pre-startup safety review, (i)For new facilities, and for modified facilities when the change requires a change in process safety information, before highly hazardous chemicals are introducedA PSSR checklist that references the change, procedures and resolved PHA recommendations
    Incident investigation, (m)(2) and (m)(7)Initiated as promptly as possible, but not later than 48 hours after the incident; reports retained for five yearsThe investigation start time, findings, resolution and retention settings
    Compliance audits, (o)(1) and (o)(5)The employer certifies an evaluation of compliance at least every three years; the two most recent audit reports are retainedAudit scheduling, findings tracked to closure and report retention

    Pre-Startup Safety Review: the Four Confirmations

    A pre-startup safety review is required for new facilities, and for modified facilities when the modification is significant enough to require a change in the process safety information (1910.119(i)(1)). Under 29 CFR 1910.119(i)(2), it confirms, before highly hazardous chemicals are introduced to the process, that:

    1. Construction and equipment are in accordance with design specifications.
    2. Safety, operating, maintenance and emergency procedures are in place and are adequate.
    3. For new facilities, a process hazard analysis has been performed and its recommendations resolved or implemented before startup; for modified facilities, the management-of-change requirements of paragraph (l) are met.
    4. Training of each employee involved in operating the process has been completed.

    The PHA and management-of-change conditions are one confirmation, not two. In the demo, ask the vendor to show a PSSR sign-off being blocked while a linked MOC action or PHA recommendation is still open, and to show which of the four confirmations each piece of evidence closes. None of the profiles below establishes a PSSR workflow on its own.

    Editorial field-walkdown checks that sit under the first confirmation (not text from the standard): every line, valve, instrument and relief device on the as-built P&ID exists in the field with matching tag numbers; bypasses, blinds and temporary connections are documented or removed; vents and drains discharge to safe locations; and calibration of safety-critical instruments is current. A structured PSSR checklist template with 1910.119(i) cross-references is available free; it has not been reviewed by OSHA.

    Seveso III Establishments in the EU

    Directive 2012/18/EU (Seveso III) is a separate regime from OSHA PSM, with lower-tier and upper-tier duties set by the dangerous substances present. Every establishment needs a written major-accident prevention policy, reviewed at least every five years (Article 8). Upper-tier establishments also prepare a safety report, reviewed at least every five years (Article 10). Before a modification that could have significant consequences for major-accident hazards, the operator reviews and where necessary updates the notification, policy, safety management system and safety report (Article 11).

    Competent authorities inspect on a plan; the interval between site visits must not exceed one year for upper-tier and three years for lower-tier establishments, unless the inspection programme is based on a systematic appraisal of major-accident hazards (Article 20). If you operate both US covered processes and EU Seveso establishments, build a requirements matrix per regime and ask each vendor to demonstrate both sets of records rather than assuming one configuration serves both. Our Seveso III compliance guide maps each duty in more detail.

    Test the Handoffs Between Processes

    Use one representative change or hazardous task in the demo. Follow its assessment, authorization, operational handover and closure, including an incomplete submission or changed condition. Check who can approve each step and which records remain available for review.

    Include any required permit workflow, risk assessment and change review. Ask whether the handoff is native, configured or implemented through another system, and price that work explicitly.

    For a management-of-change test, check whether an approved change prompts the PHA review for the affected process, the procedure and training updates and the pre-startup safety review, or whether that coordination still happens by email. Do the same for a mechanical-integrity deficiency: follow it from inspection finding to completed repair.

    Process safety products and what each record documents

    Each entry states what its researched record documents and what it does not; this is not a ranking. A broad EHS suite or permit form does not establish specialist engineering calculations, so request a quote and a workflow demonstration of the named application before judging value.

    Tekmon pays for a sponsored placement (above); its place in this list follows the same rule as every entry. How lists are ordered

    Same rule for every product: tagged “Process Safety”, “Barrier Management”, “Risk Management”, “Risk Assessment”, “Control of Work”, “Permit to Work” or “Asset Integrity”, with a sourced process safety (PHA, barrier or management-of-change) capability in its record, or one the vendor stated to us, labelled as vendor-stated. 23 qualify; the first 8 are shown, then the other 15.

    Frequently Asked Questions

    What is process safety management (PSM) software?
    PSM software supports records and workflows for managing major process hazards. Dedicated applications may cover hazard studies, change reviews, barriers or work authorization. Confirm the named application and required engineering methods rather than assuming a general EHS subscription includes them.
    What are the key elements of process safety management?
    A process safety program can involve hazard analysis, operating procedures, training, change management, mechanical integrity and incident investigation. OSHA's standard organizes requirements for covered processes. Map each applicable requirement to responsible people, procedures and records before selecting software.
    What is Management of Change (MOC) in PSM?
    MOC is a controlled review of changes that could affect process safety. Software can route assessments, approvals and follow-up actions. The organization must still define the review criteria and ensure qualified people make the decisions.
    How does PSM software support HAZOP studies?
    Dedicated hazard-study tools document structured studies and their recommendations. In our catalogue, the records of Haz360, VisiumKMS, Cority and Sphera document a HAZOP or HAZID study method, by the same rule for every product. A generic risk register is not evidence of HAZOP functionality. Demonstrate the intended methodology, action handoff and study export in the quoted application.
    What's the difference between process safety and occupational safety?
    Process safety focuses on major hazards associated with processes, including loss of containment. Occupational safety covers a wider range of harm to workers, which can also be severe or fatal. Their workflows can overlap, but incident reporting alone does not provide a process hazard analysis tool.
    Is PSM software mandatory under OSHA?
    OSHA's process safety standard sets requirements for covered processes rather than selecting a software brand. Applicability and exceptions require a facility-specific assessment. Software may help organize records, but purchasing it does not demonstrate compliance.
    How does PSM software handle SIL verification?
    SIL determination, quantitative verification and lifecycle management are distinct requirements. A brochure that lists SIL determination methods should not be treated as proof of every verification calculation, and a barrier-management source does not establish SIL verification. Require the exact calculation method, application and competent engineering review.
    How does OSHA PSM relate to Seveso III in the EU?
    They are separate regimes with different scopes. OSHA 29 CFR 1910.119 applies to covered processes in the US; Seveso III (Directive 2012/18/EU) applies to EU establishments where dangerous substances are present above its thresholds, with lower-tier and upper-tier duties. Both expect controlled change and documented prevention, but their records differ, for example the Seveso major-accident prevention policy and, for upper-tier sites, the safety report. Build a requirements matrix for each regime before assuming one deployment serves US and EU sites.
    Which PSM deadlines does OSHA 1910.119 fix?
    The standard sets several cycles: process hazard analyses are updated and revalidated at least every five years, refresher training is provided at least every three years, compliance audits are carried out at least every three years with the two most recent reports retained, and an incident investigation is initiated no later than 48 hours after the incident, with reports retained for five years. Ask each vendor to show how these dates are scheduled, tracked and evidenced.
    Can PSM software integrate with CMMS and ERP?
    Integration depends on the named product, interface and licensed scope. Ask the supplier to demonstrate asset identifiers, work-order exchange, error handling and ownership of updates with your systems. Do not assume a connector is included because the vendor offers an API.
    How long does PSM software implementation take?
    No comparable implementation timeline was verified for the products in this guide. Request a delivery plan covering data preparation, engineering review, configuration, interfaces, testing and training. Multi-site rollout estimates should identify dependencies and acceptance criteria.
    How should we assess software for different jurisdictions?
    Build a requirements matrix with qualified local specialists and ask vendors to show the relevant records and reporting outputs. A broad compliance claim does not establish support for every jurisdiction or current rule. Keep responsibility for applicability and process safety decisions within your governance arrangements.
