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


All experiments involving the use of a diamond anvil cell 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 addition, is 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 medium risk. The addition of other hazard classes may require the experiment to be categorized as high 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.

TrainingBeamline specific training in handling DACs.

Signs and Labeling – None

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

Experiment Authorization

Unless otherwise noted in the approved experiment safety plan, the Director of the APS Engineering Support Division 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 appearing in the Director of the AES's list of personnel having the authority to authorize experiments.

Hazard Control Verification

The Director of the APS Engineering Support delegates responsibility for verifying that required controls are in place to the experiment On-site Spokesperson and Beamline Management.
