A 49-year old white chemical operator, in charging an autoclave spilled a small amount of m-chloroaniline on his trousers. About one hour later he became weak and lightheaded and was told by a fellow workman that his lips were blue. Four hours after the exposure, when cyanosis was most marked, 5% of the erythrocytes contained Heinz bodies. On the next day, after hospitalisation overnight and the administration of oxygen, slight cyanosis persisted. The percentage of red cells with Heinz bodies was now 18; on the third day it was 28, and on the seventh day 20. There was no anemia. The man returned to work on the fourth day after the exposure.
