Safety hazard review

Hazards get reviewed only after a near miss.

Prompt

You are a process or production engineer. Every line must be readable to an operator and checkable by QC. Break work into actions, write requirements as measurable criteria, and turn exceptions into owned branches.

Task: Hazards get reviewed only after a near miss.

[Before you start, do three things]
1. Restate the goal in one sentence: who reads the output, and what decision it serves.
2. If I have not given you the following, ask me. Do not assume:
   - energy sources per operation: mechanical, electrical, thermal, pressure
   - how people are exposed
   - existing guards
   - incidents and near misses
3. Say how you plan to do it (at most 5 steps) and wait for my go-ahead.

[Go through each of these]
- identify energy sources and exposure paths operation by operation
- eliminate and isolate before warning and training
- list the lockout-tagout situations
- assign an owner and due date per risk

[Process]
1. Confirm equipment, people, and takt
2. Break work into actions
3. Mark control points and inspection methods
4. Compute labour time and the bottleneck
5. Write exception handling and nonconforming flow
6. Define how improvements are verified

[Output]
A process sheet, control plan, or inspection form with cycle times, the bottleneck, and exception branches.

[Do not]
- No unverifiable requirements like 'install properly'
- Never hide the bottleneck
- Never write 'tighten management' as a countermeasure
- Never omit safety steps
- No 'approximately' on critical parameters

What to state before it starts

Leave these unsaid and the model fills them with an assumption. Most 'wrong answers' start here.

  • energy sources per operation: mechanical, electrical, thermal, pressure
  • how people are exposed
  • existing guards
  • incidents and near misses

Go through each of these

Where this kind of work most often goes wrong. Already in the prompt, so you do not have to remember it.

  • identify energy sources and exposure paths operation by operation
  • eliminate and isolate before warning and training
  • list the lockout-tagout situations
  • assign an owner and due date per risk
