Troubleshooting Errors Or Abnormal Activity - formlabs Form Wash L Manual

7.3.2 Tripropylene glycol monomethyl ether (TPM)
Spilled TPM does not present an immediate fire or health hazard, but it does leave an oily
residue that can be slippery. TPM evaporates very slowly, so the spill won't dry by itself.
To clean a TPM spill:
1. Put on a pair of disposable nitrile gloves.
2. If a wash cycle is in progress, cancel the wash on the touchscreen.
3. Unplug the device from its power source.
4. Absorb excess TPM with paper towels.
5. Clean up any remaining residue using wet paper towels.
6. Dispose of tools used to clean up the spill (paper towels soaked with TPM, gloves coated
in TPM) with hazardous waste according to local regulations.
