A study was made over two winters in Chittenden County, Vermont of 15 persons injured by snowblowers and 17 neighbors who owned such machines but had not been injured. Twelve of the 15 injuries involved amputation, fracture, or laceration of fingers from contact with an impeller blade in inadequately guarded chutes. Injured persons commonly had less experience (but not significantly so) with their machines than did uninjured owners, but both reported extensive safety-related and other problems with their machines. Better design standards could probably avoid such problems. Safety education and instructions for operators are recommended. A minimum injury rate of 5.3/1,000 machines annually and 4.1/10,000 times used was estimated in this study, but the true rate probably is somewhat higher.
在佛蒙特州奇滕登县，研究人员在两个冬季对15名吹雪机受伤者以及17名拥有吹雪机但未受伤的邻居进行了调查。15起伤害事件中有12起涉及在防护不足的滑槽中与叶轮叶片接触导致手指截肢、骨折或撕裂。与未受伤的吹雪机拥有者相比，受伤者通常对自己的吹雪机操作经验较少（但差异不显著），但双方都报告了吹雪机存在诸多与安全相关的问题以及其他问题。更好的设计标准或许可以避免此类问题。建议对操作人员进行安全教育并提供操作说明。本研究估计，吹雪机每年的最低伤害率为每1000台5.3起，每使用10000次4.1起，但实际伤害率可能略高。
