Ergonomic safety analysis - development of a method for the metal industry
Ergonominen turvallisuusanalyysi - menetelmän kehittely metalliteollisuudelle [in Finnish]
A theoretical approach to the problem of accident investigation and prevention in the workplace. It involves: an analysis of the workplace as a system of interrelating parts; the breakdown of each job into its smallest elements; the development of accident probability indices for each of the elements. The method was tested by analysing jobs on a production lines in the metal industry. The material thus collected formed the basis for improved safety measures. The method is best suited for an analysis of piece work on production lines.

Respiratory symptoms and lung function in oil-mist exposed workers
The prevalence of respiratory symptoms was registered and ventilatory function was determined in 164 men exposed to aerosols from straight oils (turners), emulsions (grinders) and condensation products of evaporated oils (hardeners), and 159 controls. Average exposure time was 16.2 years. The exposed men reported more respiratory symptoms: 14% of the exposed non-smokers v. 2% of the non-smoking controls having cough at least 3 months/year. There were no significant differences between spirometric measurements and chest roentgenograms of the men exposed to oil mist and those of the controls. The lung function of 25 non-smoking exposed workers was studied further using additional lung function tests. The mean values for closing volume, slope of the alveolar plateau, total lung capacity, residual volume, elastic recoil at various lung volumes, and diffusion capacity did not differ significantly from the predicted normal.

Hygienic assessment of working conditions in plasma machining of metals
Gigieničeskaja ocenka uslovij truda pri plazmenno-mehaničeskoj obrabotke metallov [in Russian]
Levels of airborne dust, nitrogen oxides, ozone, noise and light were measured near plasma-mechanical boring and turning machines. High levels of dust were generated (at rates up to 270.0g/h); 96% of the dust particles were >1.7µm in diameter. Sound levels were comparable to or higher than those produced by metal-cutting without plasma, and in some frequency bands exceeded permissible levels. Light output in the ultraviolet, visible and short-wave infrared spectral bands was high. The intensity and spectral composition of the light depended strongly on the particular operation being conducted, on the surface properties of the workpiece and on the tuning of the plasmotron. Most of the hazards presented by the metalworking technique could be prevented or reduced by providing the machinery with appropriate enclosures.

Evaluation of an occupational respiratory exposure to a zirconium-containing dust
Comparison between 32 workers exposed to dust containing zirconium and a group of matched controls. No significant difference in respiratory symptoms was found between the exposed workers and the control group, and chest x-ray findings did not disclose any higher incidence of pneumoconiosis in the exposed workers. Expiratory lung function tests showed slightly lower values in the exposed workers, but these differences were not significant. The number of exposed workers was small, the zirconium levels were low, and time of exposure was relatively short. Systematic epidemiological studies and animal experiments are needed to demonstrate unequivocally if zirconium is harmful or not.

Quartz content of artificial abrasives
Distribuzione del quarzo negli abrasivi artificiali [in Italian]
Report of a study of the free silica content and concentration distribution in 2600 samples of artificial abrasive wheels, sheets, belts, discs and pastes used primarily in the metalworking industry over a 20-year period. The abrasives were mainly corundum (Al2O3) and carborundum (SiC). 50% of abrasive wheels had a free silica content of 0-0.22%, and only 5% contained more than 1.25%. For abrasive sheets, belts and discs, 50% contained <0.02% quartz and only 5% more than 0.65% quartz. The composition of the abrasive pastes varied considerably as did also the quartz content. In one group of pastes, which accounted for 17% of the paste samples, the quartz content ranged from 36.5 to 60.7%. Natural abrasives have now been almost entirely replaced by artificial abrasives in all abrasive tools except in the case of abrasive pastes.

Mineral oils: Studies on health effects in the engineering industry
The findings of 4 studies are presented. The cancer morbidity and mortality was studied for 792 men exposed to mineral oil mist in an engineering company for ≥5 years. 43 cases of cancer were found compared to 53 expected. Lung cancer incidence was below expected levels. Amongst turners and grinders there was evidence of increased scrotal and stomach cancer, respectively. Mortality from all causes was lower than expected. The ventilatory function was not impaired among 164 men exposed to mineral oil mist for ≥3 years. No impairment attributable to mineral oil mist was found in 25 non-smoking exposed men. The 164 exposed men had more respiratory symptoms than the 159 controls and the difference was largest for non-smokers. The cancer incidence among women in a packaging department using an anti-rust oil containing N-phenyl-1-naphthylamine was increased, probably due to the additive, and sodium nitrite corrosion inhibitor in the packaging paper.

Grinding dusts of alloyed steel and hard metal
Total elemental composition, water solubility, acid solubility and physical and magnetic characteristics of alloyed steel and cemented carbide grinding dusts were determined and measurements of magnetic lung concentration and urinary chromium (Cr) and nickel (Ni) were made in 21 stainless steel grinders. A concentration of 7-18% total Cr was found in high-alloy steel grinding dust. Total Ni concentration varied between 1.5 and 6% in different types of grinding dust. Total Ni concentration varied between 1.5 and 6% in different types of grinding dust. Dust particles had the same metallic structure as the ground stainless steel piece. Concentrations of up to 20 and 25% tungsten and cobalt (Co), respectively, were found in cemented-carbide grinding dusts, representing an enrichment of Co in dust compared with the base material. All the grinding dusts examined showed magnetic moments sufficiently high for the in-vivo measurement of lung retained dust. The average lung retention of metallic particles in stainless steel grinders was 200mg. Urinary Cr and Ni values were below the detection limit.

Videotape-based interviews in safety analysis
A method incorporating videotapes of normal work situations and a questionnaire to act as a stimulus for analysis, was evaluated as a means of safety analysis of the work sites by different groups. Videotapes of work at plate clipping machines, welding machines and lathes in 2 metalworking plants were shown to line workers, labour safety professionals and students. The results of their responses to the questionnaire-stimulated safety analysis were compared with accident statistics and results of other safety analyses. The videotape-interview technique reflected real accident development quite closely, and those with formal safety training were best able to assess hazards.

Antimicrobial agents for water-based metalworking fluids
After a review of the microbial problem (anaerobic sulphate-reducing and aerobic bacteria, fungi), in metalworking fluids, the toxicity of biocides (especially alkylamine-formaldehyde condensate biocides), added to control the microbial populations in the fluids, is discussed together with the selection and the use of biocides. Biocides are by definition poisons, the concentrated biocides tend to be highly alkaline and corrosive. But there is continuous exposure to the liquid and aerosol state only after dilution in the metalworking fluid. Approved biocides and their toxicological profiles are listed. Alternative methods for microbial control (heating, radiation) have shortcomings. Although there is no evidence suggesting that exposure to the microorganisms in the metalworking fluid is a hazard, continual exposure should be prevented.

Press noise - Reduction at source
Le bruit des presses - Réduction ŕ la source [in French]
Conventional methods of machine noise reduction (enclosures, baffles, cabins for operators) have proved inadequate or too expensive. A more effective but little explored method is to control noise at source. Ways of dealing with noise sources in presses: press components (clutch, ram, frame, ejection device, pressure system, brake, foundations); tooling (blanking, stamping and bending dies; strip or blank holders, feed control, separation of workpiece from strip); materials; peripheral equipment (feed, ejection, and waste cutting equipement).

Cancer morbidity among men exposed to oil mist in the metal industry.
788 men with at least 5 years' exposure were studied. Average exposure was estimated at 5mg/m3 up to 1965. There were 4 cases of cancer of the scrotum among the turners but none among the grinders; otherwise there were 39 cases of cancer compared to 52.9 expected. Lung cancer cases were less than expected. A non-significant increase in stomach cancer was found among the grinders.
