The sign shall be readily legible, clearly visible, and not obstructed by any item for easy viewing by customers.

WARNING
DANGER - ULTRAVIOLET RADIATION
Avoid too frequent or too lengthy exposure. As with natural sunlight, overexposure can cause eye and skin injury and allergic reactions. Repeat exposure can cause chronic sun damage, such as premature aging of the skin, which is characterized by wrinkling, dryness, fragility and bruising of the skin or skin cancer.
Wear Food and Drug Administration-Approved Protective Eyewear. Failure to wear protective eyewear may result in severe burns or long-term injury to the eyes.
Do not sunbathe before or after exposure to ultraviolet radiation. Ultraviolet radiation from tanning equipment or devices will aggravate the effects of the sun. So, do not sunbathe during the twenty-four (24) hours immediately before or immediately after using tanning equipment or devices.
Tanning indoors and outdoors on the same day, or tanning at multiple salons, or other similar occurrences is hazardous to your health.
Medications and cosmetics may increase your sensitivity to ultraviolet radiation. Consult a physician before using tanning equipment or devices if:
Women who are pregnant or using birth control pills and who use tanning equipment or devices may develop discolored skin.
If you do not tan in the sun, you are unlikely to tan when exposed to a tanning device.
If you believe that you have been injured by this tanning device, you should contact: District of Columbia Department of Health, Radiation Protection Division, 899 North Capitol Street, N.E., 2nd Floor, Washington, D.C. 20002-4210, Telephone: (202) 724-8800.
