Plant Data and Safety Boundaries
AI Privacy Rule
Keep sensitive information out of general AI prompts, including names, family details, email addresses, phone numbers, account data, customer records, employee files, financial records, legal documents, medical information, and confidential business details. Use placeholders, redacted examples, or approved systems when needed, and keep human review before important actions. AI Privacy Rules
What Manufacturing Data Should Never Enter AI Tools
Manufacturing environments hold some of the most sensitive operational data in any industry. SCADA system architecture and access credentials, chemical formulations and handling procedures, facility coordinates and security layouts, equipment serial numbers and proprietary specifications, environmental compliance records, and ongoing safety incident files all belong in this category. None of these belong in public AI tools. The data boundaries you define before starting any AI workflow are the most important governance decision you will make for your plant.
Build Your Prohibited Data List
Establish a written list of prohibited data categories specific to your facility and post it wherever teams access AI tools. Include it in onboarding for any employee or contractor who will use AI-assisted workflows. The list should cover at minimum:
- SCADA access paths, passwords, and network architecture
- Chemical formulations, handling quantities, and mixture specifications
- Facility coordinates, security layouts, and access control details
- Proprietary equipment specifications and serial numbers
- Safety investigation records and active incident case files
- Personal information about plant personnel
How to Write Safe Plant Prompts
Safe plant AI prompts use placeholders and categories instead of real operational data. Instead of pasting in a SCADA access path, describe the system type and function. Instead of including a proprietary chemical formula, reference the compound category. Instead of naming specific equipment by serial number or facility location, use role-based descriptions. This approach keeps your prompts useful while keeping critical plant data off external AI platforms.
Review Data Boundaries as AI Use Grows
What is safe to share at the documentation level may become more sensitive as you move toward AI-assisted quality review, compliance reporting, or operational planning. Treat data boundaries as a living document that evolves with your AI maturity, and review them at least quarterly alongside your broader plant AI governance policies.
Example in Practice: Rewriting a Prompt to Remove Sensitive Data
The prompt: “Here is a plant prompt I was about to use: [PASTE]. Rewrite it to remove any prohibited data — SCADA paths, chemical formulations, serial numbers, facility coordinates, personnel names — replacing them with categories and role-based placeholders, so it stays useful without exposing sensitive plant data.”
What you get back: A sanitized version of the prompt that keeps the operational intent but swaps restricted values for safe placeholders you fill in from authorized sources.
Check before using: Confirm the rewritten prompt contains nothing on your plant’s prohibited-data list before sending it to any external AI tool.
