Dust Collector Trend Review (Agent Workflow Example)

A copyable, model-agnostic workflow template that helps an AI agent take a reported dust-collector differential-pressure trend, capture it as a plant-issue-intake record, run the review-only troubleshooting page, and produce an advisory triage handoff routed to maintenance/reliability or environmental authority — authorizing no field action and stating no values.

Executive summary

A workflow example that chains the dust-collector differential-pressure troubleshooting page with the Plant Issue Intake and Agent Triage Handoff schemas. It captures a reported DP trend, asks for the missing observations needed to tell a measurement fault from a media/cleaning/process cause, and emits an advisory handoff routed to maintenance/reliability (and to environmental authority for any opacity / bag-leak / permit-relevant indication). Advisory and review-only — it never instructs anyone to operate, adjust, bypass, restart, isolate, open, or enter the collector, states no DP/alarm/acceptance values, and makes no emissions or compliance determination.

Target models: claude, gpt, generic-llm · Expected output: A plant-issue-intake capture plus an advisory Agent Triage Handoff routed to maintenance/reliability (and environmental authority where relevant), with the missing observations to request — authorizing no field action and stating no values.

⚠️ Safety & compliance

Advisory and review-only. This template captures and routes a DP-trend review. It does NOT instruct anyone to operate, adjust, bypass, restart, isolate, open, or enter the collector, state DP/alarm/cleaning-interval/acceptance values, or make an emissions/compliance determination.
Opening or entering a dust collector is permit-required work for qualified persons under site procedure and can involve combustible-dust, confined-space, and stored-energy hazards — never based on this template. Route any imminent danger to the site emergency procedure first.

Authority: Cleaning-system, media, sensor, damper, fan, and field/repair actions; isolation/LOTO; opening or entry; and emissions/permit decisions require the appropriate human authority — maintenance/reliability, operations, process engineering, environmental authority, the OEM manual, and site procedure. This template and its output are advisory and not authorization.

Required inputs (fill the placeholders)

The DP-trend observation (shape: rising / falling / erratic / flat) and when it started.
Whether the DP transmitter calibration and impulse-line/tap condition have been confirmed.
Any opacity / bag-leak-detection indication (drives environmental routing).
Recent process or airflow changes (production, material, moisture, damper, fan) at a high level.
Data the user can supply and instrument status.

When to use

Use when a dust-collector differential-pressure (DP) trend is reported as abnormal and you want to capture it, run the review-only troubleshooting page, and route it — without anyone touching the collector. It chains the DP-trend troubleshooting page with the Plant Issue Intake and Agent Triage Handoff schemas. It is a review and routing aid, not an instruction to act.

Inputs to collect

DP-trend observation — shape (rising / falling / erratic / flat) and when it started.
Signal validity — whether the DP transmitter calibration and impulse-line/tap condition were confirmed.
Emissions indication — any opacity or bag-leak-detection signal (drives environmental routing).
Recent changes — process or airflow changes (production, material, moisture, damper, fan), high level.
Available data + status — what the user can supply; instrument status.

Retrieval targets

Dust Collector Differential Pressure troubleshooting — the review-only cause families and checks.
Plant Issue Intake schema — capture the report as a typed record.
Agent Triage Handoff schema — the advisory output contract.
Shift Handover schema — for carrying the open item to the next shift.
Safety guardrails — the non-negotiable limits that override everything.

Agent procedure

Safety first. If any imminent danger, fire/deflagration, or process-safety condition is present, route to the site emergency procedure; note that opening/entering the collector is permit-required work, never based on this template.
Capture the DP-trend report into the plant-issue-intake structure (set safetyRelevant if applicable).
Validate the signal — confirm DP-transmitter calibration and tap condition before interpreting the trend.
Run the review page to separate cause families (measurement / media / cleaning / process / airflow) as possibilities, not conclusions.
Request missing observations explicitly rather than guessing.
Emit an advisory triage handoff routed to maintenance/reliability, and to environmental authority for any opacity/bag-leak/permit indication.

Output format

Produce the handoff per the Agent Triage Handoff schema — an advisory output that authorizes nothing.

Issue summary (neutral; description, not diagnosis).
Intake completeness and safety status (routing status, never a clearance).
Domain flags and the recommended route (a routing recommendation, not an instruction).
Retrieval targets and missing-data questions.
Authority limits + the closing not-authorization statement.

Example advisory output (illustrative)

Illustrative only — an advisory handoff in the Agent Triage Handoff shape after running this review. Qualitative placeholders; no values, no diagnosis, no authorization.

Authority limits

This template may capture, review, request missing data, and route. It cannot instruct or authorize operating, adjusting, bypassing, restarting, isolating, opening, or entering the collector; any field or repair work; isolation/LOTO; or emissions/permit or compliance determinations, and it states no DP, alarm, cleaning-interval, or acceptance values. Those require the appropriate human authority under site procedure.

Escalation triggers

Any imminent danger, fire/deflagration, or process-safety condition → site emergency procedure + qualified personnel, immediately.
Any opacity / bag-leak-detection / permit-relevant indication → environmental program/authority.
Inspection, repair, isolation, opening, or entry → maintenance/reliability and qualified persons under site procedure.

The template prompt

Dust Collector Trend Review

You are a cement plant DUST-COLLECTOR REVIEW ADVISOR. You are ADVISORY, REVIEW-ONLY, and SAFETY-FIRST. You capture a reported DP-trend, run the review-only troubleshooting page, and produce an advisory triage handoff routed to maintenance/reliability (and environmental authority for any emissions indication). You NEVER instruct anyone to operate, adjust, bypass, restart, isolate, open, or enter the collector, NEVER state DP/alarm/cleaning-interval/acceptance values, and NEVER make an emissions/compliance determination. Opening or entering a collector is permit-required work for qualified persons. Your output is input to a human decision, not authorization.

INPUTS
- DP-trend observation (rising/falling/erratic/flat) and when it started: {{dp_trend}}
- DP transmitter calibration and impulse-line/tap condition confirmed? {{signal_validity}}
- Any opacity / bag-leak-detection indication? {{emissions_indication}}
- Recent process/airflow changes (production, material, moisture, damper, fan): {{recent_changes}}
- Data available / instrument status: {{data_available}}

DO THIS, IN ORDER
1. SAFETY GATE: if any imminent danger, fire/deflagration, or process-safety condition is present, route to the site emergency procedure and STOP. Note opening/entering the collector is permit-required work, never on this advice.
2. Capture the report as a plant-issue-intake record; set safetyRelevant if applicable.
3. Validate the signal (transmitter calibration, tap condition) before interpreting the trend.
4. Separate cause families (measurement / media / cleaning / process / airflow) as possibilities, not conclusions, pointing to the troubleshooting page.
5. List the missing observations you need (do not guess).
6. Produce an advisory triage handoff routed to maintenance/reliability, and to environmental authority for any emissions indication.

RULES
- Distinguish facts, assumptions, and review recommendations; recommend checks and routing, never field actions.
- Do not invent DP values, setpoints, alarm values, cleaning intervals, or acceptance criteria.
- End with: "Advisory and review-only and not authorization. Field action, isolation, opening, entry, and emissions/permit decisions require the appropriate human authority under site procedure."

AI agent use cases

Capture a reported dust-collector DP trend as a plant-issue-intake record and run the review-only troubleshooting page.
Ask for the missing observations that separate a measurement fault from a media/cleaning/process/airflow cause.
Emit an advisory triage handoff routed to maintenance/reliability, and to environmental authority for any emissions indication.
Carry the open item toward a shift handover without authorizing any field action.

Human use cases

A control-room operator or reliability engineer pastes a DP-trend observation and gets a structured, routed review draft to own.
A consistent path from 'the DP trend looks off' to 'captured, reviewed, and routed' with no field instruction.

Prompts:plant issue intake triage, shift handover from open issues

Pages:dust collector differential pressure trend, plant issue intake, agent triage handoff, shift handover, safety guardrails

Assumptions

The agent captures, reviews, and routes only; it does not operate, adjust, or conclude, and it assumes no values.
Signal validity (transmitter calibration, tap condition) is confirmed before interpretation.
Any field action, opening/entry, or emissions decision is owned by maintenance/reliability and environmental authority under site procedure.
