Question PHY 07

PHY-07 How will separate equipment spaces, drains, cable openings and power shut-offs keep a fault in one part from spreading to people or the essential information service?

Why this matters

Careful separation lets the design deal with a broken screen, water entry, battery fault or high-power computer failure.

What to bring back

Draw the compartments and every opening between them. Show how each fault could spread, how power is made safe, where people are kept clear and how service returns. If electromagnetic shielding is included, define the protection to measure and the test needed.

What we know so far

• Straddie Disaster Kiosk Pitch.pdf — reviewed source; public copy can be added through the evidence process
• Professional review and comparison of proposed improvements (When this work overlaps professional or public-authority responsibilities, compare the proposal and Luke's research with applicable industry/global best practice and relevant legal-engine sources. Record differences, reasonable improvements and deficiencies, with the responsible reviewer and response. Routine authorised drafting and wiki work can advance.)

The source catalogue states what the references establish. The decision and approval record retains its own status.

Separate faults by design: keep public controls, stored energy, power conversion and information service in reviewed compartments. Map every opening and shared cable, provide labelled isolation, and ensure one failed module can be removed while an independent notice layer explains available service.

Compartment and isolation drawing

AI-generated adaptation of an existing pattern. Have the electrical designer compare separate cabinets with protected internal sections, documenting fault paths and safe maintenance access. Use enclosure accessories only within their documented installation conditions and inspect the completed openings.

Research basis: Rittal protective roof SZ 2475000 · Permanently connected generators.

Independent continuity cartridge

AI-generated future concept. Develop a small independently powered notice-and-status cartridge that remains readable when the main cabinet is isolated. A tested physical boundary would separate it from high-energy faults; a retained image would always carry its update time.

Research basis: E Ink technology benefits.

Examples and local differences

• Permanently connected generators: AI transfer assessment: Source isolation is an explicit design responsibility in fixed generator connections. Local difference to check: A kiosk's battery and DC fault paths require their own engineered protection and inspection.

Evidence to bring back next

• Review all drains, glands, barriers and isolation points on the assembled design.
• Define any electromagnetic shielding claim as a separately measured protection objective.
