The hazard controls described herein apply to all experiments involving various types of hazardous chemicals. Hazard controls (associated with other hazard classes) may also apply to experiments in this hazard class.
|
|
|
Experiments involving previously reviewed hazard controls are, in general, low or medium risk experiments. Work with highly toxic chemicals, flammable chemicals, larger quantities of materials, etc. may change the classification to high risk.
Experiments involving new equipment, processes, or materials, or modified hazard control schemes are high risk experiments.

If your work at the APS will generate hazardous chemical waste, you must work with your host Beamline to ensure hazardous chemical waste is stored and disposed of properly. NOTE: Except in certain cases, waste chemicals and chemicals in general may not be disposed of down laboratory, restroom, or storm drains.
|
|
|
Unless otherwise noted in the approved experiment safety plan, the PSC Deputy Associate Laboratory Director of Operations delegates the authority to authorize an experiment in this hazard class to a member of the APS Experiment Safety Review Board and resident beamline personnel having the authority to authorize experiments as listed in the ESAF system. Approval by both the host beamline and APS Experiment Safety Review Board are mandatory prerequisites for experiment authorization.
|
|
|
The PSC Deputy Associate Laboratory Director of Operations delegates responsibility for verifying that required controls are in place to the experiment On-Site Spokesperson and Beamline Management.
