Comments
May be absorbed through skin; A cholinesterase inhibitor; [ICSC] Moderately irritating and highly toxic to the eyes of rabbits; Non-irritating to rabbit skin and non-sensitizing to guinea pig skin; [HSDB] “The average of two baseline respective cholinesterase activity determinations three days apart, with no exposures to enzyme inhibiting pesticides for at least 30 days, is recommended for each worker prior to exposure to cholinesterase inhibitors because of large inter-individual differences in published baseline values. To be established at least once a year. Removal from workplace exposures is recommended until the cholinesterase activity returns to within 20% of baseline.” [TLVs and BEIs]
