101 CDOS Week 7: Sun Safety Published June 30, 2008 By Staff Reports 354th Fighter Wing Safety Office EIELSON AIR FORCE BASE, Alaska -- Limit Time in the Midday Sun The sun's rays are strongest between 10 a.m. and 4 p.m. Whenever possible limit exposure to the sun during these hours. Seek Shade Shade is a good source of protection, but keep in mind that shade structures (e.g., trees, umbrellas, canopies) do not offer complete sun protection. Remember the shadow rule: Watch Your Shadow. No Shadow, Seek Shade! Wear a Hat A hat with a wide brim offers good sun protection to your eyes, ears, face, and the back of your neck - areas particularly prone to overexposure to the sun. Cover Up Wearing tightly woven, loose-fitting, and full-length clothing is a good way to protect your skin from the sun's Ultra Violet rays. Wear Sunglasses that Block 99 to 100 percent of UV Radiation Sunglasses that provide 99 to 100 percent UVA and UVB protection will greatly reduce sun exposure that can lead to cataracts and other eye damage. Check the label when buying sunglasses. Always Use Sunscreen Apply a broad spectrum sunscreen with a Sun Protection Factor of at least 15 or higher liberally on exposed skin. Reapply every two hours, or after working, swimming, playing, or exercising outdoors. Even waterproof sunscreen can come off when you towel off, sweat, or spend extended periods of time in the water. Avoid Sunlamps and Tanning Parlors The light source from sunbeds and sunlamps damages the skin and unprotected eyes. It's a good idea to avoid artificial sources of UV light. Watch for the UV Index The UV Index provides important information to help you plan your outdoor activities in ways that prevent overexposure to the sun. Developed by the National Weather Service (NWS) and EPA, the UV Index is issued daily in selected cities across the United States.
