_IEEE ltd 76-1974 Revision of IEEE Std 76-1908 IEEE Guide for Acceptance and Maintenance of Transformer Askarel in Equipment 13. Recommended Handling Precautions It is generally accepted that the exposure to askarel is not hazardous, provided simple pre cautions are taken. Most people can handle askarel in the same manner as insulating oil without fear of adverse effects. Some people are allergic to askarel, and continued exposure may result ill skin irritation. Therefore, direct contact with askarel and its vapors, particu larly when hot, should be avoided. This, com bined with personal cleanliness, should con- ititutc an adequate safeguard against harmful effects. Eye protection (glasses, shields, etc) are required. The use of any typo glove should be avoided. Medicinal washes or detergents followed by an application of cold cream or sil icone-bearing hand lotions' have been suc cessfully used to eliminate irritation resulting from askarel coming into contact with an open cut or skin abrasion. A drop of castor oil has been found to neutralize, in most cases, ir ritation caused by contact of askarel with the eyes. . Exposure to concentrated askarel vapors should be avoided, particularly in closed un- ventilaled rooms. As with many volatile liq uids, the vaporization of askarel increases rap idly with temperature. Therefore, ventilation which is adequate for handling askarel at room temperature may not be adequate for handling askarel at elevated temperatures. The gases producod when askarel is de composed by very high temperatures or an electric arc in the presence of air or organic in sulating materials contain a high percentage of hydrogen chloride and small percentages of carbon dioxide, carbon monoxide, and oxygen. Very small concentrations of this com bination of gases are very unpleasant and irri tating, thus giving ample warning of their presence. The all-purpose canister-type gas masks are suitable for protection from gases liberated from decomposed askarel. Such n Sillcsrt. MONS 095586
