- Use dark glasses (shade 1.7 to 3.0) when looking inside the kiln through peepholes or the door to protect your eyes from infrared radiation and potential explosions. Regular sunglasses do not provide adequate protection.
- Wear heat-resistant gloves when handling peephole plugs or the kiln door, as they can cause burns.
- Never open the kiln lid while it is on, except for controlled troubleshooting tests. Opening the lid while powered can cause electrocution, and cracks from propping it open are not covered by the warranty.
- Always wear heat-resistant gloves when opening a hot lid, and never open the lid if the kiln temperature exceeds 121°C (250°F).
