Analysis of air samples indicated that concentrations of respirable free silica from sandblasting equipment used inside an unventilated painting room greatly exceeded the current OSHA standard and NIOSH recommended criteria. Lack of ventilation in the design materials studio resulted in excessive wood dust concentrations; levels averaged 29 mg/m3 which was well above the evaluation criteria of 5 mg/m3. Noise levels measured in the woodworking area of the design materials studio, and near the melting furnace located in the foundry of the ceramics studio, exceeded the 100-dBA limit recommended by NIOSH for a 2 hr continuous exposure. Lack of proper ventilation in the design materials painting room and in the printmaking darkroom resulted in exposures to toxic concentrations of toluene (from spray painting) and methyl cellosolve acetate (from KPR photo etching chemicals). Results of atmospheric sampling indicate that exposure to wood dust, crystalline silica, methyl cellosolve acetate, and toluene were excessive, and capable of producing both acute and long term health effects.
空气样本分析表明，在未通风的喷漆室内使用的喷砂设备所产生的可吸入游离二氧化硅浓度大大超过了职业安全与健康管理局（OSHA）的现行标准以及美国国家职业安全卫生研究所（NIOSH）推荐的标准。设计材料工作室缺乏通风导致木屑粉尘浓度过高；平均水平为29毫克/立方米，远高于5毫克/立方米的评估标准。在设计材料工作室的木工区域以及陶瓷工作室铸造车间的熔炉附近测得的噪音水平超过了NIOSH推荐的2小时连续暴露100分贝的限值。设计材料喷漆室和版画制作暗室缺乏适当通风，导致工作人员接触到有毒浓度的甲苯（来自喷漆）和醋酸甲基溶纤剂（来自KPR光刻化学品）。大气采样结果表明，接触木屑粉尘、结晶二氧化硅、醋酸甲基溶纤剂和甲苯的情况超标，并且可能产生急性和长期健康影响。
