  1. I think my fume hood is malfunctioning.  What should I do?

Close the hood sash and do not use the hood until EHRS confirms it is functioning properlyContact your building administrator to open a work order.  If the hood is not put back into service within 5 days of contacting your building administrator, contact EHRS. 

Chemical Storage

Chemical Storage

  1. Can all acids be stored together in the same cabinet?

Strongly oxidizing acids (e.g. Perchloric acid, nitric acid) are incompatible with organic materials, including organic acids (e.g. Glacial acetic acid).  These compounds react vigorously.  Mineral acids (ie. HCl, H2SO4) can be stored with either acid type.  If a separate cabinet is not available, use secondary containment to segregate incompatible acids.
