Did You Know?

1.    Mismanagement of reactive organics, such as tetrahydrofuran and ethers is one of the most expensive aspects of our hazardous waste program?  Expired, unstabilized reactives must be “detonated” on site before then can be removed from campus.  This is quite an expensive proposition!  Do not order more of these materials than you need before their expiration date.
2.    If a piece of glassware is dropped on the floor and does not break on impact, it still has been weakened to the point where it might easily break in a future use.  Kimberly Clark gave a real-life demonstration of this at a recent glassware safety presentation.  Be sure to dispose of glassware that has been dropped, rather than continue to use it and risk an accident.
3.    Gas cylinders have a time limitation for safely holding compressed gas.  This pressure rating lasts between 5 and 10 years.  If you have had a gas cylinder in your lab over 5 years, have a look to see the expiration date, which should be stamped into the cylinder itself.  Get rid of cylinders over or approaching their time limitation!
