Experiment Hazard Class 10.2 – Ultraviolet Light
This hazard classification applies to all experiments involving the use of ultraviolet radiation generating equipment.Ultraviolet light (UV) is non-ionizing radiation in the 180 to 400-nanometer wavelength region of the electromagnetic spectrum. Ultraviolet light poses hazards:
- Eyes hazards – inflammation, cataracts, retinal damage
- Skin hazards – sunburn, accelerate wrinkling, increased risk of skin cancer
- Possible ozone generation
Experiments involving only experiment hazard class 10.2 qualify for medium risk. The addition of other hazard classes may require the experiment to be categorized as high risk and undergo additional reviews.
Experiment Hazard Control Verification Statements
Engineered Controls – Shield or contain UV as close to the source as possible. Interlock if feasible.
Procedural Controls – ACGIH (American Conference of Governmental Industrial Hygienists) suggests that ultraviolet exposure not exceed 1mW / cm^2.
Design Reviews and Equipment Inspections – Output measurement for UV of the device, characterization,
Hazard Control Assistance - Consultation is available through the ESH Coordinators and ESQ-IH. Please contact the local floor coordinators for arrangements.
Training – No additional training is specified for this hazard class.
Labeling –APS ESH Coordinators can provide signs at request, AES ESH Coordinator 2-6714 or XSD ESH Coordinator 2-4192
Do Not Expose Eyes and Skin to Ultraviolet Light
Rays May Be Harmful to Unprotected Eyes and Skin
Or For Equipment
UV Radiation Hazard
Use Only with Shielding In Place
Protect Eyes and Skin from UV Exposure Warning
UV generating Device
Personal Protective Equipment – UV resistant safety glasses, UV resistant safety goggles, UV resistant face shield, lab coat, and gloves
Monitoring – None required after initial review and control implementation.
Unless otherwise noted in the approved experiment safety plan, the Director of the APS Experiment 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' list of personnel having the authority to authorize experiments. Approval by both the host sector and the APS Experiment Safety Review Board are mandatory prerequisites for experiment authorization.
Hazard Control Verification

APS Engineering Support Division delegates the authority to authorize an experiment
in this hazard class to a member of the APS Experiment Review Board and any
of the persons in the beamline personnel that appear in the list of Beamline
Manager personnel authorized to approve experiments.
