# Worker Safety

Worker safety is a founding priority, on equal footing with the environmental
commitments:

- **Safety training**: proper, structured training for all operators and
  maintenance staff, starting with the vendor-led commissioning training and
  extending into an ongoing in-house program. The pressing line combines
  hydraulics (~180 bar), saturated steam (10 bar / 180 °C), and hot PVC, and
  every one of these demands trained, deliberate handling.
- **Clean rooms for galvanics**: silvering and stamper electroforming will
  run in dedicated clean rooms with controlled access, proper ventilation and
  exhaust, and decontamination procedures for people and equipment leaving
  the area. Plating chemistry stays inside its containment.
- **Personal protective equipment**: appropriate PPE (overalls, gloves,
  goggles, and process-specific protection) is mandatory per work area, in
  line with the equipment vendor's site requirements (exhaust work benches,
  fire protection) and local regulations.
- **Lifting and machine service**: the overhead crane needs trained
  operators and slingers, a lift plan for every machine move, and the
  periodic engineer inspections Thai law sets for cranes. A machine is
  only disconnected and lifted after lockout: electrical isolation, steam
  vented, hydraulics depressurised including the accumulator. Welding and
  grinding stay in the workshop's hot-work corner under a permit. Detail
  in [crane, workshop and tours](crane-workshop-tours.md).
- **Visitors** never share the floor's hazards: tours run in a glazed
  corridor with its own air and no PPE requirement.

Safety infrastructure (training program, clean-room specification,
decontamination workflow) will be planned alongside the equipment, not after
it.
