Production of ..cap alpha..-Si thin-film photovoltaic cells entails extensive handling of many toxic and/or pyrophoric gases which present potential significant occupational hazards. Toxic gas by-products of the manufacturing process are likely to be produced in small quantities and can be controlled by use of available technology; controlled emissions from normal operation will probably pose no hazards to public health. Accidental release of gases stored on site, however, may endanger both plant personnel and the surrounding community. Safe handling of explosive SiH/sub 4/ gas requires careful gas system design, the fundamentals of which are discussed. Gases in the ..cap alpha..-Si deposition processes can be handled safely, provided that certain safety features are incorporated in the design of facilities and that users take appropriate precautions. Hazard management options are discussed.
