Safety MessageWhy Peroxides tend to explode violently and cause serious injury or death to researchers. Under normal storage conditions, formed peroxides can accumulate in some chemicals and may explode when subjected to heat, friction or shock. It is important that all researchers learn to recognize and safely handle peroxidizable chemicals. What Ethers are the most notorious peroxide formers, many other organic materials, such as acetals, allyic alkenes, dienes ... are peroxidizable chemicals (see attached document for classified 4 lists of 180 chemicals).How Peroxides tend to form in chemicals as a function of age. Therefore, it is important that the user maintain a storage-record of the peroxidizable chemicals (date received, date opened, expiration and testing date). By the expiration date (24 hours to 18 months, see below), the chemicals should be either disposed or tested. Any chemicals with a peroxide content > 100 ppm should be disposed.What to do 1) Check the link to see if you are using peroxidizable chemicals. 2) For all new purchased peroxidizable chemicals, the owner has the responsibility to put the storage-record label on the container. 3) If you find an old peroxidizable chemicals in the lab, do not move it, contact Dr. David Kinninson and Antonios.
