nnovative <br /> onstruction <br /> olutions <br /> 4 . 2 . 13 NON - IONIZING RADIATION <br /> Currently the only source of non - ionizing radiation identified as part of this scope of work is <br /> ultraviolet light ( sun light ) . Should another source be identified an addendum to this HASP will <br /> be issued and discussed as part of the daily tailgate meetings and as part of any applicable Activity <br /> Hazard Analysis ( AHA ) . <br /> Health effects regarding ultraviolet ( UV ) radiation are confined to the skin and eyes . <br /> Overexposure can result in many skin conditions, including erythema ( redness or sunburn ) , <br /> photoallergy ( skin rash ) , phototoxicity ( extreme sunburn acquired during short exposures to UV <br /> radiation while on certain medications ) , premature skin aging, and numerous types of skin <br /> cancer . Implement the following controls to avoid sunburn . <br /> Limit Exposure Time <br /> • Rotate staff so the same personnel are not exposed all of the time . <br /> • Limit exposure time when UV radiation is at peak levels ( approximately 2 hours before <br /> and after the sun is at its highest point in the sky ) . <br /> • Avoid exposure to the sun or take extra precautions when the UV index rating is high . <br /> • Reference UV Index using mobile device . <br /> Provide Shade <br /> • Take lunch and breaks in shaded areas . <br /> • Create shade or shelter using umbrellas , tents, and canopies . <br /> • Fabrics such as canvas , sailcloth , awning material and synthetic shade cloth create good <br /> UV radiation protection . <br /> • Check the UV protection of the materials before buying them . Seek protection levels of <br /> 95 percent or greater and check the protection levels for different colors . <br /> Clothing <br /> • Reduce UV radiation damage by wearing proper clothing, for example , long sleeved shirts <br /> with collars, and long pants . The fabric should be closely woven and should not let light <br /> through . <br /> • Head protection should be worn to protect the face , ears, and neck . Wide - brimmed hats <br /> equipped with a neck shade offer added protection . <br /> • Wear UV- protective sunglasses or safety glasses . These should fit closely to the face . <br /> Wrap - around style glasses provide the best protection . <br /> 28 <br />
