The concentration of PAA can be calculated from the equilibrium constant and the risk of exposure estimated.<br /><br />In normal home use, the quantities used are very small and so the risk of exposure is minor. However, if the same mixture were used on a commercial scale, such as food processing operation spraying the mixture all day, then occupational exposure may be significant. <br /><br />Many chemicals commonly used in the home have stringent occupational exposure levels. Very few people are concerned about bleach in the home, but OSHA has ceiling PEL 1 ppm.ChemDAQhttps://www.blogger.com/profile/17325881830772675169noreply@blogger.comtag:blogger.com,1999:blog-399973311524080801.post-37071244854204835512014-02-15T01:16:23.211-05:002014-02-15T01:16:23.211-05:00What amount of dilution and neutralization is need...What amount of dilution and neutralization is needed to make peracetic acid acceptable to put into a sewage system?Mount Shasta Inquirerhttps://www.blogger.com/profile/04654969327044500899noreply@blogger.comtag:blogger.com,1999:blog-399973311524080801.post-19074010528979633872014-01-16T17:59:28.881-05:002014-01-16T17:59:28.881-05:00Does the combination of white vinegar at 5% and hy...Does the combination of white vinegar at 5% and hydrogen peroxide at 3%, readily available in a grocery store, become peracetic acid?
