It’s the dose that makes the poison.
How much ethanol are we talking? Half a dozen 8 ounce jars might not be an issue, but if you are exceeding a gallon total aggregate quantity, you might be in a more risky situation, and want to store these in a flammable rated cabinet.
A flammable cabinet will prevent this material form becoming involved in any adjacent fires.
Check with your local fire code and officials and see what quantity flammable liquids you can store without a permit. You may also consider not storing them all in the same room or laboratory (don’t put all your eggs in one basket).
Also, what are they stored in? Specimens are usually stored in glass so they can be observed, but don’t use old food containers. Best to have containers with good integrity, proper fitting closures, and non-breakable when possible.
I hope this puts you on the right track. Use secondary containment appropriately, and communicate the hazard on the container and the storage area.

Hello everyone,
I was curious of your thoughts and practices regarding the storage of specimens in an ethanol solution. Do you then store them in a fire cabinet due to the
ethanol? We currently have some specimens stored in a regular cabinet in an Ecology lab space. They have always been stored this way, but I recently became the Chemical Resource Officer and want to make sure things are being treated correctly. This topic,
however, seems to have mixed answers in the research I've found. Most items say to store in a cool, dark place but do not mention it needing to be in a fire cabinet. Any thoughts or guidance would be greatly appreciated!
Thank you,
Charish Dean (she/her)
