油泵漏油是第三有色金属公司选矿厂长期存在的问题。不仅浪费油,影响文明生产,而且当油漏到矿砂上时,还会影响金属回收。去年,磨矿钳工组曾根据兄弟单位的经验,先后进行了四次改进,但未能完全杜绝漏油现象。今年三月份,职工又提出用开回油线的方法,利用业余时间安装了一台漏油严重的油泵进行了试验,效果很好,连续运转了两昼夜,一滴不漏。现已正式安在9号球磨机 相似文献

"A factor analysis was performed on the intercorrelations between the responses of 1000 university students, most of whom were Arabs, to 38 statements about accidents and minor mishaps. A general factor was found to run through all the statements indicating that individuals who admit to having accidents in one situation also indicate that they have been involved in accidents in other situations. Such a finding does not contradict the notion of 'accident proneness' and suggests the possibility that some minor accidents and mishaps might be predictive of subsequent major accidents.

Researchers have been giving increased attention to the role larger organizational variables play in safety and accidents. Although generally neglected by this research, the nature of the exchange relationships between individuals, leaders. and the organization appears to have safety-related implications. The present research linked leader-member exchange (LMX) and perceived organizational support (POS) to safety communication, safety commitment, and accidents. Data were collected from 49 supervisor–group-leader dyads in a manufacturing facility. The results indicated that POS was significantly related to safety communication and that LMX was significantly related to safety communication, safety commitment, and accidents. Support was also found for a structural model linking POS and LMX to safety communication, safety commitment, and accidents. Implications of these findings for safety and social exchange research are outlined. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

Subjects with ankylosing spondylitis (AS) have an increased incidence of deaths from accidents and violence, which is due in part, but perhaps not entirely, to the vulnerability of the affected spine to fractures. The present study covered all the 71 subjects (58 men and 13 women) who had died in Finland in 1989 and who were entitled under the nationwide sickness insurance scheme to receive specially reimbursed medication for AS. The death certificates of an earlier cohort study dealing with mortality in AS were also re-examined. Sixteen subjects (14 men and two women) in the 1989 mortality series had died of accidents and violence. Nine of the deaths (three accidents, two suicides and four alcohol poisonings) were alcohol related. The relative risk of such deaths in subjects with AS compared to the Finnish population as a whole was 2.64 (95% confidence interval 1.44-4.84). In the cohort study, 16 deaths had been due to accidents and violence, the expected number being 11.4. Eight of the 16 deaths had been alcohol related. Uncontrolled use of alcohol is an important determinant in the surplus of deaths from accidents and violence in Finnish patients with AS. 相似文献

Sleep-disordered breathing and motor vehicle accidents in a population-based sample of employed adults 总被引:1,自引:0,他引:1
Studies have consistently shown that sleep apnea patients have high accident rates, but the generalizability of the association beyond clinic populations has been questioned. The goal of this investigation was to determine if unrecognized sleep-disordered breathing in the general population, ranging from mild to severe, is associated with motor vehicle accidents. The sample comprised 913 employed adults enrolled in an ongoing study of the natural history of sleep-disordered breathing. Sleep-disordered breathing status was determined by overnight in-laboratory polysomnography and motor vehicle accident (MVA) history was obtained from a statewide data base of all traffic violations and accidents from 1988 to 1993. Men with five or more apneas and hypopneas per hour of sleep [apnea-plus-hypopnea index (AHI) > 5], compared to those without sleep-disordered breathing, were significantly more likely to have at least one accident in 5 years (adjusted odds ratio = 3.4 for habitual snorers, 4.2 for AHI 5-15, and 3.4 for AHI > 15). Men and women combined with AHI > 15 (vs. no sleep-disordered breathing) were significantly more likely to have multiple accidents in 5 years (odds ratio = 7.3). These results, free of clinic selection bias, indicate that unrecognized sleep-disordered breathing in the general population is linked to motor vehicle accident occurrence. If the association is causal, unrecognized sleep-disordered breathing may account for a significant proportion of motor vehicle accidents. 相似文献
