# Triage cleanroom particle excursions using Gmail, OpenAI, and Telegram

> Quick overview This workflow monitors a Gmail inbox for cleanroom particle-counter excursion alerts, parses the email into structured measurements, uses OpenAI to classify severity, routes by zone criticality, and either logs minor events or runs an investigation sub-workflow that can trigger a tool-interlock API call and Telegram notifications. How it works 1. Polls a Gmail inbox every minute for messages from the particle monitor with “EXCURSION” in the subject. 2. Extracts Zone, Tool, Measured Count, ISO Class Limit, and Particle Size from the email text and calculates the exceedance ratio. 3. Sends the normalized excursion details to OpenAI (gpt-4.1-mini) to return a structured severity (Minor/Major/Critical) plus a shutdown recommendation. 4. Tags the record with a protocol tier based on cleanroom zone criticality (Support, Process, or Litho/EUV). 5. Logs Minor excursions directly to an n8n Data Table as “Logged - no investigation required.” 6. For non-Minor excursions, runs a sep
