The effects of loggers' personal protectors and the safety equipment of chain saws were investigated with a postal questionnaire. The sample included 1,200 loggers. The main purpose of the inquiry was to collect data on accidents and near-accidents; special attention was paid to the role and behavior of protective devices in both accident and near-accident situations. Twenty-seven percent of power saw operators reported incidents (near-accidents) which had occurred within the last year and in which some personal protector or piece of safety equipment had prevented harmful mechanical contact. The workers estimated that the average absence from work due to these reported near-accidents would have been 15 workdays if the injury had not been prevented. Sixty percent of the near-accidents occurred during limbing operations, and 30% during falling. The protective equipment which most often prevented injuries was safety boots, which were followed by the safety helmet and leg protectors. The chain of the saw was stopped by the safety padding of the protective equipment in every other near-accident involving chain saws. The chain was blocked by padding material in every sixth situation . In 10% of the near-accidents, the chain perforated the protective equipment.
通过邮政问卷调查的方式，对伐木工人的个人防护装备和链锯安全设备的效果进行了调查。样本包括1200名伐木工人。调查的主要目的是收集有关事故和未遂事故的数据；特别关注防护装置在事故和未遂事故情况下的作用和行为。27%的电锯操作员报告了过去一年内发生的事件（未遂事故），其中一些个人防护装备或安全设备避免了有害的机械接触。工人们估计，如果没有这些防护装备，因这些报告的未遂事故导致的平均缺勤天数将达15个工作日。60%的未遂事故发生在砍枝作业期间，30%发生在伐木期间。最常防止受伤的防护装备是安全靴，其次是安全帽和护腿。在每两起涉及链锯的未遂事故中，防护装备的安全衬垫会使锯链停止运转。在每六起情况中，锯链会被衬垫材料卡住。在10%的未遂事故中，锯链会穿透防护装备。
