Experiment Hazard Class 5.2 – High Pressure - Large Volume Press


This hazard classification applies to all experiments involving the use of the GSE-CARS large volume press. Samples may be in the form of metal foils, single crystals, or powdered chemicals in sample holders. Other hazard classifications and their associated hazard controls may also apply to experiments in this hazard class. For example, if laser heating is applied, the experiment safety plan must incorporate the relevant Class 4 hazard controls.

Experiment Category

Experiments involving previously reviewed hazard controls qualify for medium risk category.

Experiments involving new equipment or modified hazard control schemes are categorized as high risk.

Experiment Hazard Control Verification Statements

The hazard controls listed below must be incorporated into the experiment safety plan for each APS beamline experiment involving the GSE-CARS large volume press.

Engineered Controls – The APS-approved GSE-CARS procedure covering use of the large volume press addresses requirements for engineered controls.

Procedural Controls – The owner of this equipment has an SOP for using the equipment.

Design Reviews and Equipment Inspections – If the experimenters bring a sample holder from offsite, the holder must be provided to the GSE-CARS Safety Coordinator (or delegate) for inspection prior to use.

Training – Orientation to the use of the GSE-CARS procedure for use of its large volume press

Signs and Labeling – Signs and labeling associated with this hazard class are already in place at the facility. Other hazard classes might have sign or labeling requirements that would have to be incorporated into the safety plan.

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 all GSE-CARS personnel appearing in the APS list of CAT personnel having the authority to approve experiments.

Hazard Control Verification

The Director of the APS Engineering Support Division delegates responsibility for verifying that hazard controls are in place the experiment On-site Spokesperson and personnel delegated the authority to perform this task by GSE-CARS management.
