CLEANROOM OPERATIONS · Workflow idea

Make particle excursions visible without skipping the human response.

Bring the reported zone, tool, particle count, applicable limit, and particle size into a clear excursion record. Use the proposed severity to organize attention, while qualified staff confirm the reading and decide what action is required.

01 / The starting point

A clear request.
A useful direction.

An excursion notice from a cleanroom particle monitor

“Review the reported zone, tool, measured count, applicable class limit, and particle size. Organize the event by its measured exceedance and zone criticality, and prepare the appropriate investigation or notification handoff.”
An example request · Make it specific to your team.

02 / The work

6 tasks.
One useful outcome.

Turns a particle-monitor notice into a consistent record, highlights the reading relative to its stated limit, and organizes investigation and follow-up by zone criticality.

  1. Capture the excursion notice

    Gather the reported zone, tool, measured count, stated class limit, particle size, and original alert details.

  2. Check the reading against its stated limit

    Calculate the reported exceedance ratio and make the measured value and comparison available to the reviewer.

  3. Organize by severity and zone

    Prepare a proposed minor, major, or critical classification and identify the applicable zone-importance tier.

  4. Record lower-severity events

    Keep a traceable record of events designated for logging, while leaving the final interpretation to cleanroom staff.

  5. Prepare investigation handoffs

    Route higher-severity cases for the required contamination or corrective-action investigation and bring the outcome back to the event record.

  6. Notify the responsible people

    Prepare the appropriate facilities or safety-team notice and obtain qualified human direction before any containment or equipment action.

03 / The result

Something useful.
Something to build on.

A structured excursion record with a proposed severity, investigation status when needed, and a team handoff. Any equipment interlock or shutdown remains subject to an authorized human decision.

The handoff

A structured excursion record with a proposed severity, investigation status when needed, and a team handoff. Any equipment interlock or shutdown remains subject to an authorized human decision.

Keep in mind

Treat the proposed classification as a prompt for review, not a substitute for approved cleanroom procedures. Qualified staff verify the source reading and applicable limit; no equipment shutdown should be based solely on an automated assessment.

04 / Make it yours

Set the brief.
Set the standard.

A few choices shape the work around your team.

Choose the alert source and required details

Confirm how monitor notices are identified and which zone, tool, reading, limit, and particle-size details staff need.

Document zone and limit guidance

Have cleanroom owners maintain approved zone criticality, applicable limits, and review procedures.

Prepare investigation and event records

Choose where event histories and investigation outcomes are kept and how they are linked for later review.

Name qualified decision owners

Identify who assesses severity, leads investigation, receives notifications, and authorizes any interlock or shutdown decision.

Put your next idea to work.

Start with your brief. Make the process your own.
