Esters (<C12)
Colorless liquid with a persistent banana-like odor; [NIOSH]
Used as a solvent for surface coatings, photographic films, nail polish, printing inks, and fabric finishes; also used as a flavoring agent, an odorant, a dry cleaning agent, and an insecticide; [ACGIH]
Esters may induce narcosis in animals, but workers' exposures are limited by irritating effects. See appendix in: [Dick RB, et al. Chemicals in the workplace: incorporating human neurobehavioral testing into the regulatory process. Am J Ind Med. 1998 May;33(5):439-53.] The pentyl acetates are sensory irritants in the work environment. At higher levels in animal experiments, they cause narcosis, hepatotoxicity, and developmental toxicity. 1-Pentyl acetate has low dermal toxicity, and Skin notation is not warranted. [ACGIH]

Excerpts from Documentation for IDLHs
Basis for original (SCP) IDLH. . The chosen IDLH is based on the statement by Browning [1965] that exposure to 4,000 ppm of a mixture of n-amyl acetate and isoamyl acetate produced complete loss of reflexes in rabbits within an hour [Koelsch 1912], and on the statement by Sax [1975] that 5,000 ppm n-amyl acetate produced deep narcosis in cats in 30 minutes. . . . Human data: Somnolence has been reported after exposure to 952 ppm for 30 minutes [Lehmann 1913].
