Classify your proposed change, screen it against OSHA PSM 1910.119(l) triggers, determine the required review pathway, and generate a pre-populated MOC checklist. For PSM-covered facilities using any change management program.
A Replacement in Kind (RIK) is a change that meets the original design specification exactly — same equipment, same material, same procedure. If any specification differs, it is a change requiring MOC.
This tool routes standard changes. PSM-covered facilities often need custom MOC workflows integrated with their permit system, PHA re-validation triggers, training records, and document control. SafeGuard Projects builds digital MOC systems tailored to your site's program.
Discuss a Custom MOC System →| Requirement | Details |
|---|---|
| Technical basis | Document the technical rationale for the change |
| Impact on safety | Assess impact on safety and health |
| Modifications to procedures | Update all affected SOPs before startup |
| Necessary time period | Define duration — especially for temporary changes |
| Authorization | Require sign-off per site's authorization matrix |
| Employee notification | Notify and train all affected employees before startup |
| Process hazard analysis | May trigger PHA re-validation if significant change |
| Class | Trigger | Typical Timeline |
|---|---|---|
| RIK | Exact replacement — no spec change | No MOC needed |
| Standard | Minor change, low risk, no PSM triggers | 1–5 days |
| Major | Significant change, PHA or SIS impact | 5–30 days |
| Emergency | Safety-critical, requires expedited review | 24–72 hrs |
