| Comments |
A mucous membrane irritant similar to isopropyl alcohol, n-propyl alcohol produces narcosis in animals inhaling high concentrations. It causes severe liver injury in chronic feeding studies of laboratory animals. [ACGIH] Irritating to the eyes; Inhalation of high concentrations can cause CNS depression; [ICSC] |

| Excerpts from Documentation for IDLHs |
Human data: Mild irritation of the eyes, nose, and throat have been reported at 400 ppm [Nelson et al. 1943]. It has been reported that 5,700 mg/kg is the lethal oral dose [Durwald and Degen 1956]. [Note: An oral dose of 5,700 mg/kg is equivalent to a 70�kg worker being exposed to about 94,000 ppm for 30 minutes, assuming a breathing rate of 50 liters per minute and 100% absorption.] |
