We do use a standard house-hold refrigerator for storage of ethanol/water samples with a limit of 10 mL per sample.  Larger quantities are allowed if vapor tight double containment is used, but these are considered only on a case-by-case basis.

Hi Nancy,

Take a look at this link for descriptions of domestic refrigerator explosions when flammables were stored in them.  Includes pictures.

Can house-hold refrigerators (non-explosion proof) be safely used in labs that store and/or use flammables such as acetone and pet. Ether?


Would there be a threshold amount(say 500 mL) below which it could be safe? 


I was wondering if there is a written standard for this somewhere that I could use to answer these questions in labs where policies are being considered.
