	Ethyl Formate
		Ethyl formate is a colorless liquid with a pleasant, fruity odor; it is highly flammable and poses a dangerous fire and explosion risk.
		Before a worker is placed in a job with a potential for exposure to ethyl formate, a licensed health care professional should evaluate and document the worker's baseline health status with thorough medical, environmental, and occupational histories, a physical examination, and physiologic and laboratory tests appropriate for the anticipated occupational risks.
		Ethyl formate is not subject to EPA emergency planning requirements under the Superfund Amendments and Reauthorization Act (SARA) (Title III) in 42 USC 11022.

		Ethyl alcohol was first detected in the interstellar medium in 1975 by a team led by Ben Zuckerman, but proved elusive in subsequent searches.
		In a recent article, they show that in Orion the spatial distribution of ethyl alcohol is similar to that of other, large oxygen-bearing molecules such as methanol, methyl formate and dimethyl ether and is associated with a hot core called the Compact Ridge cloud.
		The detection of such large amounts of ethyl alcohol, and previous detections of even larger amounts of methanol, in hot cores suggests that grain surface chemistry may be very efficient in producing alcohols.

	Re: What are the accepted scents for isoamyl formate & ethyl methanoate
		Isoamyl formate (also known as isoamyl methanoate) naturally occurs in apples, so it has an "apply smell." It is used in perfumes to mimic the scents of plums, berries, apple cider, raspberries, oranges, and pears.
		Ethyl formate derived from cabbage is used to mimic the scents of raspberries, melons, mulberries, flberries, and currant.
		Ethyl formate derived from raspberries is used when the scents of tea, mulberries, beer, strawberries, or butter are desired.
