Methyl iodide is a monohalomethane and with a chemical formula CH 3 I. Acute exposures to methyl iodide have frequently occurred in the workplace. Predominantly, neuropsychiatric symptoms of acute exposure to monohalomethanes consist of headache, nausea, vomiting, drowsiness, dizziness, giddiness, diarrhea, confusion, ataxia, slurred speech, paralysis, convulsions, delirium, coma, and death. We report two cases who presented to our emergency services after accidental exposure to methyl iodide for a short duration. These case reports highlighted concurrence of frankly psychotic features and acute confusional state in workers vulnerable to industrial exposure to toxic chemicals. Understanding the mechanism of neuro-toxicity will perhaps throw some light on co-existence of both psychiatric and neurological symptoms. Awareness of these toxic effects at vulnerable work places will lead to timely and appropriate interventions. Importance of safety precautions and education of both workers and supervisors cannot be overemphasized here
