Risks
Inherent
- Heat runaway (CPU fault, contacts welded)
- Faulty thermocouple causing heat runaway / instability / cracking
- Contact with water/leak
- Material falling onto it / other people working too near / unclear that is hot
Operator driven
- Flammable material near
- Hot handles, etc
- Dust
- Unclear it is on / hot
- Opening while hot
- Bare wire touching
- Looking into it / infrared radiation
