Mortality of welders, shipfitters, and other metal trades workers in Boilermakers Local No.104, AFL-CIO
This historical prospective method was used to evaluate the mortality experience of 8,679 members of a metal trades union, employed in shipyards, metal fabrication shops, small boat yards, and field construction from 1950 to 1976. Relative to rates for U.S. men of comparable age and race, the risk of death from all causes combined was 0.99. Excesses of 40% and 60% occurred for malignant and non-malignant respiratory disease deaths, respectively, beginning 20 years after first employment. These excesses increased with increasing interval from first employment and the non-malignant respiratory disease excess was also related to cumulative exposure. Causes of death that occurred at significantly greater than expected rates in specific job classifications included pneumonia in welders, accidents and suicide in shipfitters, and emphysema in burners.

Work postures and movements in maintenance work on agricultural machinery
Työasennot ja -liikkeet maatalouskoneiden kunnossapitotöissä [in Finnish]
Report on a preliminary study of the work postures and movements of mechanics servicing and repairing agricultural machines. The Ovako work posture analysis system was employed and observations were taken every 30sec. A total of 2,300 observations were made. During this work a mechanic's back was in upright position less than half the time. The back was bent during 32% of working time (in work at a workbench the back was bent even more often). Either one or both of a mechanic's hands were raised to shoulder level for at least 20% of the time. A worker's own weight plus the weight of a load causes great strain on the legs when one or both legs are bent. Bent leg positions occurred 8% of the working time. Mechanics often had to crawl, climb or sit on the floor. Conclusion: the position of back, legs and arms caused strain during 40% of the working time.

Spontaneous abortions among women employed in the metal industry in Finland.
From union files and hospital discharge records, spontaneous abortions were analysed among Finnish metal workers between 1973 and 1976 (35.000 women). Among these, 195 spontaneous abortions were recorded. The ratio was significantly higher than the corresponding ratio for all Finnish women. A particularly high-risk industry appeared to be the production of radios, television sets, and their components. Exposure to solder fumes (from colophony flux) was suggested to explain the increased risk.

Industrial chromium poisoning in small- and medium-sized electroplating factories (Supplements 1 and 2).
Health examinations were performed on 3 occasions between 1956 and 1960 in 140, 172 and 114 workers, respectively, at chromium electroplating factories manufacturing bicycle parts. Skin changes including ulcer were found in 87, 76 and 85%, nasal septum perforations in 11, 6 and 10%, and nasal mucous membrane changes including nasal septum perforation in 61, 83 and 97% respectively. There were no radiological indications of lung cancer except exaggeration of lung markings. Twenty years after the first studies, a visit to one of the factories showed that automation of the plating process and changes in working methods had reduced workers' exposure to chromic acid and dust.

Cutting fluids may be fine for the machines - Are they harmful for the worker?
Bra smörja för maskiner - bara smörja för människor? [in Swedish]
An investigation in Swedish metalworking plants showed that 42% of machine tool operators exposed to cutting fluids had health problems due to this exposure (generally skin disorders such as oil acne or eczema). Attempts were made to reintroduce soap water, but soaps contain resinous acids which are also allergens, and there is a problem of rust on the machines. The introduction of vegetable oils, mainly containing colza oil, caused a sharp drop in the incidence of dermatoses, but the machines became dirty. Furthermore, these oils are favourable to the propagation of bacteria, and have to be renewed frequently. The best solution would seem to be: use of mineral oils, the composition of which should be previously assessed from the occupational hygiene aspect; personal cleanliness; and regular maintenance of the coolant systems.

Studies on working conditions and the health of operators of machine tools with coolant systems, and animal experiments, have shown not only that cutting oils produce folliculitis and dermatoses, but that their areosols (oil mists and pyrolysis products) have toxic effects on the respiratory system. Chronic respiratory diseases, functional and biochemical changes, and a reduction in immunobiological resistance have been observed in cases of prolonged exposure. Preventive measures proposed are: automation of machining tasks, enclosure of the machining zone, periodical cleaning of the coolant system, personal hygiene, medical supervision.

Computed projections of noise levels showed that a reduction in the amplification of a noise source by the premises by a factor of 7.5dB at 50m from the noise source was possible, but also showed that the noise level in the work place remained unacceptable, resulting in the necessity to enclose the noisiest presses. This work proceeded in 2 stages, reducing the noise level in almost all passages between machines to below 85dB(A).

Statistical study of the health effects of trichloroethylene in 188 workers exposed in the auto-screw machine industry
Etude statistique de la pathologie professionnelle du trichloréthylène chez 188 travailleurs exposés dans l'industrie du décolletage. [in French]
MD thesis. A computerised, multidisciplinary study is reported. The effect of trichloroethylene was confirmed in unspecific subjective manifestations such as a state of intoxication or somnolence at the workplace, headache, insomnia, odour intolerance. In others - irritative cough, gastralgia, nausea and vomiting, vertigo, chest pressure, palpitation - the role of trichloroethylene was less clear. Objective signs found with some frequency were: trigeminal neuralgia, contact dermatitis, conjunctivitis, loss of visual acuity, and dyschromatopsia suggesting optic neuritis. A simplified form was established for an epidemiological study of workers most exposed to trichloroethylene.

Occupation and bronchial carcinoma.
All newly diagnosed bronchial carcinoma cases (212 men, 61 women) in Uppsala, Sweden, were studied for 5 years. There was a significantly higher proportion of metal and construction workers, while agricultural workers were under-represented. The incidence of pleural plaques was 4 times higher than expected. In certain occupations dust has an additive effect on the carcinogenic effect of smoking.

Pulmonary fibrosis associated with work with cemented carbides
Fibrose pulmonaire liée au travail des métaux durs. [in French]
The case of a 59-year-old worker employed in boring cemented tungsten carbide workpieces, suffering from pulmonary fibrosis, is reported. In addition to the classic signs observable by light microscope, investigation of a lung biopsy specimen by electro microprobe indicated the characteristic tungsten mark. This case is typical for disease caused by cemented carbide dust. Given the incidence and characteristics of hard metal fibrosis, it should be included in the list of occupational diseases in France.
