BPs are used not only in specialized cosmetic preparations for skin protection against the carcinogenic effect of UV radiation they are also added to pharmaceuticals and many everyday products such as body lotions, shampoos, bubble baths, and hair sprays. These compounds are used for the packaging of synthetic materials in order to extend the shelf life of stored products that could be affected by the influence of sunlight. Other application areas are tire additives, castings, coatings, pigments, textiles, and other products, to increase their resistance to UV radiation [49,64,73,74]. 

Rapid growth of nuclear power has brought to a head the problem of storage and burial of radioactive waste products. Now, more than 250,000 tons of exhausted nuclear fuel has accumulated in the world. In light of this, creation of new radioactive-resistant structural materials intended for protection, storage, and burial of radioactive waste products is necessary. Application of RubCon for protection against radiation in enclosed radioactive waste product storehouses is discussed below.

Full-face masks of class 3 are designed for use by emergency teams, fire fighters, or rescue teams in mining operations. Class 2 masks are by far the most common full-face masks in use. In comparison to class 3 masks they possess a decreased resistance, especially against heat radiation. Because class 1 full-face masks offer significantly reduced protective properties, they are not allowed to be equipped with coimectors for round or central screw threads or screw threads of type M 45 X 3. FuU-face masks are permitted for use in combination with external air supply as weU as with particle or gas filters. All use areas for class 1 to 3 full masks are listed in Table 6.20. 

Aramids have been developed from the need to enhance the chemical stability of polyamides. Because of the stability of aromatic rings, aramids also have higher tensile strength and thermal resistance than aliphatic polyamides. These qualities make aramids popular for use in impact resistance applications. However, aramids - along with PA - have low UV resistance. If used in outdoor applications, they must be heavily coated to protect against UV radiation. 

If a potential exists for skin exposure to UV lasers (200-400 mn), use skin covers and/or sunscreen. Most gloves will provide some protection against laser radiation. Tightly woven fabrics and opaque gloves provide the best protection. A laboratory jacket or coat can provide protection for the arms. For class 4 lasers, give consideration for using flame-resistant materials. Use protective clothing when exposed to levels of radiation that exceed exposure limits for the skin. 

The paints can be liquids or powders that are applied to surfaces to make a dry coating for protective or decorative purposes. The protective functions include, for example, prevention of corrosion, resistance to fire and protection against fungi, marine growth and radiation. Reduction of friction, control of illumination and electrical insulation are other functions of paints. The decoration of homes and public buildings has become more common than previously and has thus increased the need for high-quality paints that do not cause health problems. (Fischer and Adams 1990 Rose and Vance 1997).
