Results and discussion

Results:
MTHPA was classified as "Sa", danger of sensitization of airways by the German MAK commission (Commission for the investigation of health hazards of chemical compounds in the work area).
Substances classified as "Sa" can cause symptoms of the airways and also of the conjunctiva (substances causing airway sensitization).
Positive control results:
no details given
Negative control results:
