Effective safety inspection programs are scheduled, event-driven, and continuous:
- Regular / Routine – Monthly, quarterly, or semi-annually based on risk profile (construction: weekly; office: quarterly). Codified in the safety management system.
- Pre-start / Pre-shift – Daily walkthroughs in high-risk environments (confined space, excavation, energized work) to catch immediate hazards.
- Post-incident – After any injury, near-miss, property damage, or environmental release; root cause analysis + corrective actions.
- Post-change – New equipment, process modification, chemical substitution, facility renovation; verify no new hazards introduced.
- Hazard-triggered – Immediate inspection when a hazard is reported or observed.
- Construction / Renovation phases – Progressive inspections at critical milestones (excavation, framing, MEP rough-in, final).
- Programmatic – Integrated with risk assessments, JHAs, training audits, PPE checks, ergonomic evaluations; part of continuous improvement (PDCA).
Frequency should be risk-proportionate, documented, and reviewed annually for effectiveness.
