Experiment Hazard Class 5.1 – High Pressures Created By Diamond Anvil Cells

Applicability

All experiments involving the use of a diamond anvil cell (DAC) to apply high pressure to a sample.  Samples may be in the form of metal foils, single crystals, or powdered chemicals in sample holders.  The research sample in the DAC is also under high pressure in a diamond anvil cell.

If laser heating is applied, Experiment Hazard Class 4 must also be cited in the hazard assessment.

Experiment Category

Experiments involving only experiment hazard class 5.1 qualify for low risk.  The addition of other hazard classes may require the experiment to be categorized as a higher risk.

Experiment Hazard Control Verification Statements

Engineered Controls – None.

Procedural Controls – Only those required by Beamline Management.

Design Reviews and Equipment Inspections – The diamond anvil cell must be provided to the Beamline Safety Coordinator (or delegate) for inspection prior to use.

Training – Beamline specific training in handling DACs.

Signs and Labeling – None

Personal Protective Equipment – Safety glasses with side shields that meet ANSI Z87.1 requirements.

Experiment Authorization

Unless otherwise noted in the approved experiment safety plan, the PSC Associate Deputy 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.

Hazard Control Verification

The PSC Associate Deputy Laboratory Director of Operations delegates responsibility for verifying that required controls are in place to the experiment On-Site Spokesperson and Beamline Management.
