The use of dry ice has increased dramatically in poultry processing plants because of changes in the fast food industry. Concentrations of carbon dioxide in four such plants were measured and were found to exceed the Immediately Dangerous to Life and Health Level (50,000 ppm) inside holding coolers where ventilation is poor. In other areas, where dry ice is delivered to poultry packages, time-weighted average exposures can exceed the threshold limit value of 5000 ppm by substantial margins, even if local exhaust ventilation systems are present. Reports of adverse health effects from carbon dioxide exposure and various control measures are reviewed. Recommendations regarding sampling and analytical techniques also are presented. Operators of poultry plants where dry ice is used need to recognize the occupational hazards of exposure to carbon dioxide.
由于快餐行业的变化，干冰在禽类加工厂的使用量急剧增加。对四家这样的工厂中的二氧化碳浓度进行了测量，结果发现，在通风不良的储存冷却器内，二氧化碳浓度超过了立即威胁生命和健康的浓度水平（50,000 ppm）。在其他干冰被运送到禽类包装处的区域，即使有局部排风通风系统，时间加权平均暴露量仍可能大幅超过5000 ppm的阈限值。本文回顾了二氧化碳暴露对健康产生不良影响的报告以及各种控制措施。还提出了关于采样和分析技术的建议。使用干冰的禽类加工厂的经营者需要认识到接触二氧化碳的职业危害。
