01
Responsibility before and after acceptance
Customer or site
- Use only approved material and follow the documented closure procedure.
- Keep the C12 within time, temperature, orientation, and access limits.
- Preserve the seal and all identifiers.
- Provide controlled access during the confirmed handoff window.
- Report damage, prohibited input, missed collection, or a held state.
Authorized service operator
- Records acceptance and secures the package in its approved transport system.
- Maintains route, vessel, temperature, custody, and exception records.
- Retains service custody through delivery or a documented transfer.
- Provides the acceptance receipt and handles a downstream facility refusal.
This is a proposed service-contract allocation. Contracted service custody does not necessarily remove responsibility imposed by local law. Regional legal, carrier, packaging, and waste-classification review remains required.

Customer-visible collection states
The normal sequence and exception states use the same labels in Desk Toilet Cloud, DT Fleet, service messages, and custody records.
| State | Meaning | Action |
|---|---|---|
| Collection ready | C12 is installed and eligible for exchange. | Schedule pickup. |
| Pickup scheduled | A service window is confirmed; customer custody continues. | Keep the C12 installed until the planned exchange when capacity permits. |
| Prepared for handoff | The removed C12 is closed, checked, upright, and latched in the rigid vessel. | Keep it in approved storage until the handoff window. |
| Awaiting collection | The package is at the approved handoff point during the confirmed window. | Customer custody still continues. |
| Collection delayed | Pickup was cancelled, weather-delayed, or missed before acceptance. | Return indoors immediately and keep the original storage clock. |
| Collection held | Route, processing, age, temperature, or eligibility is suspended. | Do not stage the package; wait for an authorized exception plan. |
| Inspection required | Damage, leakage, unconfirmed closure, unreadable IDs, or prohibited input was reported. | Do not move or clean internally. Restrict access and request service. |
| Accepted into custody | An authorized operator verified and recorded the package. | Contracted service custody begins. |
| In transit | The operator holds transport custody. | Route and transfer records remain attached to the C12 ID. |
| Processing received | An authorized facility records receipt or refusal. | The service operator retains responsibility if the facility refuses it. |
| Sanitized replacement ready | An equivalent pool cartridge completed the proposed return checks. | Replacement stock may re-enter the exchange pool. |

04
Storage before acceptance
These are proposed pilot limits pending biological-storage, pressure, odor, and transport validation.
Never beyond the 14-day first-use lock
Monitor the indoor service area
Transport cap uppermost
Supplied transit vessel only
- Use a secure indoor service area that is dry and protected from sunlight, freezing, heat, water, and impact.
- Keep the vessel away from food handling, children, pets, public traffic, unauthorized staff, and an occupied workstation.
- Do not refrigerate a C12 with food.
- Do not reset the removal clock after a delayed or rescheduled pickup.
05
Delays and exception handling
Priority exception service is available only inside an active territory. It is not an emergency-response service, and no universal response time is promised before operator contracts exist.
| Condition | Required response | Service treatment |
|---|---|---|
| Provider cancellation or weather | Return the vessel indoors immediately. Keep it upright, preserve the original removal time, and reschedule. | No proposed rescheduling fee. Priority handling is arranged if the 72-hour limit may be exceeded. |
| Route or processing suspension | State becomes Collection held. Do not stage the vessel or begin use that would exhaust sanitized stock. | Desk Toilet must provide an authorized route or exception plan. |
| NFC cannot be read | Collector uses the recessed human-readable identifier or 2D fallback after server authorization and manual verification. | If both paths fail, state becomes Inspection required and standard pickup stops. |
| Damage, leakage, or closure not confirmed | If installed, do not remove. If detached, do not carry it. Restrict access and request specialist inspection. | No standard pickup. Do not tape, relabel, wipe the closure, or improvise an overpack. |
| Two full or held cartridges | The unit becomes unavailable. Store both correctly and use existing restroom facilities. | Request priority exception service. Never consolidate or discard contents. |
| Outside service area | Founding-pilot hardware is not activated. If moved out of territory, stop use and contact service. | No mailing, customer drop-off, private transport, or municipal disposal. |
If there is an immediate risk to people or the building, follow the site’s existing emergency procedure. DT Collection is not a substitute for emergency services.

Processing and sanitized replacement
Processing and cartridge return are separate controlled activities. No treatment occurs at the customer site.
- 01Processing received
An authorized facility records receipt or refusal and applies its permitted acceptance, processing, and residual rules.
- 02Contents removed
Accepted contents enter the facility’s permitted process. A refusal remains the service operator’s responsibility.
- 03Shell workflow
The reusable shell enters a separate proposed controlled cleaning and disinfection workflow.
- 04Return checks
Service seals and caps are inspected or replaced. Identity, closure, leak, pressure-path, and visible-condition checks must pass.
- 05Replacement ready
An equivalent exchange-pool C12 becomes available. It may not be the customer’s original shell.
The sanitization chemistry, worker protection, microbial acceptance criteria, reuse limit, and reject path remain pending biological-safety and engineering review. No validated sanitation result is claimed.
