A Minor Disaster Closer to Home

Background
- Oven controls are not standard - off on different ovens are different directions.
- The previous oven control turned counter-clockwise for off.
- The oven under consideration turned clockwise for off.
The Event
- A very nice apple crisp was being made.
- It had completed it before supper.
- It got very crisp - turned on broiler instead.
The nonstandardized controls between units led to proactive interference.
