Answer "how many safety officers do I need?" with a transparent, risk-based estimate from your headcount, risk class, sites, shifts and contractor mix — cross-checked against OSHA, Saudi Aramco (GI 2.100), OSHAD, France and Morocco benchmarks — plus a one-page management justification (Word).
⚠️ Important: there is no universal legally-mandated safety-officer ratio in most jurisdictions — OSHA, OSHAD, France and Morocco set duties and competence, not a fixed headcount ratio. This tool gives a defensible, risk-based estimate and benchmark to support a staffing decision; some clients/operators (e.g. Saudi Aramco GI 2.100) do impose contractual ratios. Always check your sector rules, client requirements and actual workload before deciding.
