+# Facility: Security and Site Systems
+
+What the plant needs beyond the production machinery. Access control and
+CCTV are set requirements; the rest of this list is what a plant of this
+profile definitely needs, to be refined during site design.
+
+## Physical security
+
+- **Access control**: zoned, not just at the gate. Minimum zones: general
+  production, galvanics clean room (controlled access is already a safety
+  requirement), chemical storage, master/stamper archive, server/IT room,
+  finished goods and shipping. Badge or biometric, with logs.
+- **CCTV**: entrances, perimeter, loading dock, production floor, chemical
+  storage, archive. Retention policy to be defined; Thai PDPA (personal data
+  protection) applies to camera footage of staff and visitors.
+- **Intrusion alarm** with monitoring, covering off-hours.
+- **Perimeter and lighting**: fencing appropriate to the site, lit
+  approaches and parking.
+- **Visitor management**: sign-in, escort rules, PPE issue at entry, no
+  unaccompanied access to production or galvanics.
+
+## Protecting the irreplaceable
+
+- **Master and stamper archive**: fathers and mothers are unique metal
+  parts; a destroyed father can mean re-cutting and re-plating a release.
+  The archive room needs fire-rated construction or safes, climate control,
+  access logging, and an off-site strategy for the most critical masters.
+- **Client audio**: pre-release music is a high-value leak target, and
+  labels ask about it before they send masters. Isolated storage for client
+  files, encrypted transfer and at-rest storage, strict need-to-know access,
+  and a written policy the sales team can show clients.
+- **Chemical inventory**: silver nitrate is valuable and regulated; nickel
+  salts are hazardous. Locked storage, inventory tracking, and controlled
+  issue to the galvanics team.
+
+## Fire and life safety
+
+- **Fire detection and alarm** throughout; suppression matched to each zone
+  (hot PVC and hydraulic oil in pressing, chemistry in galvanics, paper and
+  cartons in packaging/finished goods, and the boiler room).
+- **Boiler room safety**: the steam generator (10 bar, 180 °C) needs its own
+  room, safety valves and interlocks, and inspection per Thai boiler
+  regulations (Department of Industrial Works requirements, licensed boiler
+  operator).
+- **Emergency equipment in galvanics**: eyewash stations and emergency
+  shower at the plating line, spill kits, and neutralizing agents.
+- **Emergency lighting, marked exits, assembly point**, and first-aid
+  coverage on every shift.
+
+## Plant systems and monitoring
+
+- **Utility monitoring and interlocks**: fume-extraction interlocks on the
+  galvanics line (no extraction, no plating), steam and compressed-air
+  pressure monitoring, leak detection, and safe-shutdown sequences.
+- **UPS and controlled shutdown** for the IT room, access control, alarms,
+  and the press PLCs (a power cut mid-cycle should never leave a press in an
+  unsafe state; the battery stack can carry critical loads).
+- **Lightning protection and grounding**: northern Thailand has intense
+  storm seasons; the PV array, steel structures, and electronics all need a
+  proper LPS and earthing design.
+- **Environmental monitoring**: temperature and humidity logging in
+  production (the process spec calls for 20-26 °C, 35-60% RH), the archive,
+  and the clean room.
+
+## Compliance anchors (Thailand)
+
+- Factory license (Ror.Ngor. 4) and Department of Industrial Works
+  requirements for the machinery classes and chemical quantities involved
+- Boiler registration and licensed operator requirements
+- Hazardous substance registration for the plating chemistry
+- PDPA compliance for CCTV and personnel data
+- Local fire codes and building permits during construction
+
+All of this belongs in the site design brief, so contractors quote it from
+day one rather than retrofitting it.
