Unattended Operations

In past newsletters, we have discussed the danger of leaving experiments and other operations involving hazardous materials unattended. EH&S will address one spegific aspect on this in the future.

You may not be aware that only a very few chemical fume hoods on campus are connected to ermgency power, should the electricity in the building fail. Unattended experiments left running in a fume hood will likely disperse hazardous fumes into the laboratory air should there be a power failure in the building. It is critical that laboratories prepare a plan for unattended fume hoods. Please have a look at the lable that will soon be applied to all applicable fume hoods. Then please prepare an emergency plan. If the plan does not properly address the hazard that may be preoduced, then the experiment CANNOT run unattended.
