## Narrative

EE was recharging the Cooltech HVAC machine.  EE closed the R134A refrigerant tank valve and then proceeded to remove the line set.  There was a refrigerant discharge when the line set was removed because the R134A refrigerant tank valve was not completely closed all the way.  The EE received a chemical burn on their left hand as they attempted to reconnect the line set.
