Not one program, a set
Describing Optifora as a single "OHS program" understates it. The catalogue groups modules under subject headings: compliance and risk; chemicals, safety data sheets and explosion protection; field work (permits, incidents, emergencies); people (training, health surveillance, competence); assets (equipment, periodic inspection, maintenance, measurement); environment and energy (waste, energy, carbon); ergonomics and musculoskeletal; workplace environment and exposure; corporate (contractors, committees, surveys, reporting); trust (signature, verification, integration).
The choice belongs to the organisation
A manufacturing site and an office organisation do not need the same things. So the platform does not arrive with everything switched on; the organisation picks its own set from the module catalogue and adds or removes later. The catalogue page states plainly what each module does and where it stands — ready, in development, or on the roadmap.
The content in this answer centre follows the same scope: the questions look at the whole platform, not only at occupational safety.
