# Facility: Security and Site Systems

What the plant needs beyond the production machinery. Access control, CCTV,
and whole-factory HVAC control are set requirements; the rest of this list
is what a plant of this profile definitely needs, to be refined during site
design.

## Climate control: whole-factory HVAC

The entire factory runs under continuous HVAC control, covering temperature,
humidity, and particulate matter (PM). This is a set requirement, not an
option per room.

- **Temperature and humidity**: the process spec already demands 20-26 °C at
  35-60% relative humidity for pressing; the same conditioning extends to
  the whole building so materials, masters, packaging stock, and electronics
  never sit outside controlled conditions. PVC compound and paper packaging
  are both humidity-sensitive.
- **Particulate matter**: filtration for the whole plant, with stricter
  tiers by zone. Dust in a groove is an audible defect, so the cutting room
  and galvanics clean room run at the tightest spec with positive pressure;
  pressing and packaging run cleaner than ambient; offices and logistics at
  a baseline tier. Northern Thailand's burning season (roughly February to
  April) brings some of the world's worst PM2.5 episodes, so intake
  filtration and building tightness must be designed for those peaks, not
  for average days.
- **Continuous monitoring and alarms**: temperature, humidity, and PM
  sensors logging in every zone, with alarms on excursions, tied into the
  plant monitoring below.
- **Energy design**: conditioning a whole factory in a tropical climate is
  a major electrical load on top of the 250 kW process cooling, and it must
  be included in the solar PV and battery sizing from the start. Heat
  recovery from the press hall (steam, hydraulics, and hot PVC all reject
  heat) and from compressors should feed the design rather than fight it.

## 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**: the whole-factory HVAC monitoring above
  (temperature, humidity, PM in every zone), with the archive and clean room
  as the most tightly alarmed spaces.

## 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.
