Examination of the accident records from the telecommunication industry covering some 100 000 engineers over a 12-month period showed that 25% of accidents resulting in more than three days' sick leave gave rise to back injuries. Handling accidents and falls accounted for 65% of three-day-plus accidents; handling accidents alone gave rise to 65% of back injuries. The absolute numbers of accidents have been compared with the total population of engineers to estimate the effects of age or occupation on levels of hazard; certain occupations constituting 33% of the engineers' population suffered 70% of all three-day-plus accidents. Accidents occurred most frequently in the group aged from 31 to 48 years. Other significant factors affecting the occurrence of accidents were time of year and duty experience of the workers.
对电信行业12个月内约10万名工程师的事故记录进行检查后发现，导致超过三天病假的事故中有25%引发了背部受伤。搬运事故和跌倒占三天以上事故的65%；仅搬运事故就导致了65%的背部受伤。已将事故的绝对数量与工程师总数进行比较，以估计年龄或职业对危险程度的影响；占工程师总数33%的某些职业遭受了所有三天以上事故的70%。事故最常发生在31岁至48岁的人群中。影响事故发生的其他重要因素是一年中的时间和工人的值班经验。
