## Safety note
|
||
|
||
The hot alkaline process (`BOX_HOT`) operates at 138–143 °C, **above the atmospheric
|
||
boiling point of water**. Water contact with the hot caustic bath causes explosive
|
||
boiling ("bumping"). Parts must be completely dry before immersion. See the
|
||
`hazard_notes` field on the process type for the full safety brief.
