Manifestation of resistance to change: the case of workers whose working tools become automated
L'expression de la résistance au changement: le cas de travailleurs concernés par l'automatisation de leur outil de travail [in French]
This research project was conducted in a large Belgian metal manufacturing plant. In particular, it was concerned with the installation of a machine-finishing centre. Certain factors were noticed among the workers that were liable to affect their productivity during the transition period. Different interviewing techniques permitted an understanding of how workers react to the proposed technological change. If it is accepted, it is accepted in principle and not necessarily in those aspects that concern the workers directly. This lack of acceptance of details of the changeover seems to be due to faulty training and to a lack of consistency in the different stages of the changeover.

Biological monitoring of cobalt exposure, based on cobalt concentrations in blood and urine
Cobalt exposure level and its concentrations in blood and urine were determined for 175 hard metal workers and for 20 office workers. The exposed workers had significantly higher cobalt concentrations in both blood and urine. The relationships between exposure level and cobalt concentrations in blood and urine were linear and positive. Thus, cobalt concentration in the blood or urine can be used as an exposure indicator. With cobalt exposure of 100µg/m3, the cobalt concentration was 0.57 to 0.79µg/dL in blood and 59 to 78µg/L in urine with 95% confidence limits. In workers using respirators, the cobalt concentrations in the blood and urine decreased to 2/5 and 1/8, respectively, of its level in those not using respirators.

Hygienic aspects of the information model of noise
Gigieničeskie aspekty informacionnoj modeli šuma [in Russian]
In a rolling mill, noise dose during a shift and noise entropy were measured at two levels for 117 workers. Tonal audiometry, tonometry, pulsometry and rheocencephalography were performed before and after a shift. A questionnaire survey of 60 coalworkers and metalworkers was also performed. Increasing entropy at constant dose altered the threshold of hearing. The rate of reception of information before a shift was greatest when both entropy and dose were minimal, whereas after a shift the rate was highest for maximum entropy and minimum dose. Temporary and permanent threshold shifts responded in the same way to changes in the variables. Thus, the biological activity of noise depends not only on its energy and entropy, but also on their interrelationship.

New ways of soundproofing metal-forming machines
Neue Wege der Kapselung von Umformmaschinen [in German]
To obtain a combination of primary and secondary soundproofing measures, a total enclosure of machines is required. The enclosures must meet all requirements of occupational safety, serviceability, safety of transportation and tool changing. A soundproofing enclosure with corresponding modules already successfully used on several types of presses has been developed for a wide field of application. On an automatic machine for can lids, a reduction of 15dBA in the overall noise level has been obtained. This is near the theoretical value of the obtainable sound reduction.

Experience with the introduction of torches for semiautomatic welding with fume aspiration in assembly plants
Opyt vnedrenija gorelok dlja poluavtomatičeskoj svarki s otsosom aėrozolja na zavodah metallokonstrukcij [in Russian]
Description of a new electric welding torch. It has a lighter supply cable than previous models, which permits the torch and its air and electric lines to be made long enough to enable continuous welding of large vats, trusses and columns. Compressed air is supplied to cool the handle. A compressed-air ejector provides suction for an aspirator channel in the torch. Exhaust air passes through a specially designed filter where welding fume is collected. Depending on conditions in the factories where the new torch has been introduced, efficiencies of fume collection range from 70 to 100%, and fume levels in the welders' breathing zones have been reduced 15-20-fold. Substantial amounts of money have been saved by the elimination of the construction costs and heat losses associated with local ventilation systems.

Respiratory illness in the construction trades - 1. The significance of asbestos-associated pleural disease among sheet-metal workers
314 asbestos-exposed construction workers (USA) were assessed for the rate of roentgenographic and lung function abnormalities. Pleural abnormalities were common (70% in workers with >30 years employment) and showed a significant correlation with decreased forced vital capacity. In contrast, forced expiratory volume in 1s showed a stronger association with smoking than with pleural abnormality. Cigarette smoking was shown to increase the effect of asbestos in causing pleural disease. Pleural disease in asbestos-exposed workers is an indicator of exposure and of early impairment of pulmonary function.

Nordic expert group for documentation of exposure limits - 57. Oil mists
Nordiska expertgruppen för gränsvärdesdokumentation - 57. Oljedimma [in Norwegian]
The composition and properties of oil mist depend on the kind of oil used and on the circumstances in which the oil is used. Cancer of the skin (particularly scrotum) and oil folliculitis (acne) were previously frequently reported among workers exposed to cutting oil, but the oil was straight and contained polycyclic aromatic hydrocarbons. However, water-soluble (emulsified) solvent-refined mineral oil is now most frequently used. This cutting oil may cause allergic and non-allergic contact dermatitis. Oil pneumonia has been reported as a consequence of inspiration of large amounts of mineral oil. Some cases of cancer of the respiratory system have also been recorded. Lower oil mist concentrations produce irritation and hyperplasia, metaplasia and a loss of cilia in the nasal mucosa. The irritant effect of oil mist on the respiratory system should serve as a general starting point in the determination of occupational exposure limits for oil mist. The carcinogenic effects of oils with special compositions and additives must be appraised.

Mortality of workers in an automobile engine and parts manufacturing complex
Report on a proportionate mortality ratio study conducted on workers in an integrated automobile factory composed of forge, foundry and engine (machine and assembly) plants. Observed deaths (769) over a 10-year period (1970-1979) were compared with expected numbers based on a national (USA) and local standard for men. For the whole group there were no significant differences between observed and expected numbers of deaths. For various subgroups of workers (subdivided by race, plant, length or period of employment) significant increases were found for certain causes of death (such as cancers of the pancreas, bladder and rectum). The use of cutting oils is suggested as a possible cause of these excess deaths.

Noise in cold press shops
Le bruit dans les ateliers de frappe à froid [in French]
This research project covered: the measurement of noise levels in a number of enterprises; an acoustic study examining the efficiency of various means of noise reduction (enclosure, sound-absorption treated ceilings, noise screens) depending on the arrangement of the presses and the layout of the shops; a review of the literature presenting possibilities of noise reduction at source. The conclusion is that, given the high sound levels in this industry (90-102dB(A)), the only means of reducing noise levels to about 85dB(A) is the complete enclosure of machines. Noise reduction at source, applied together with enclosure, would lead to even lower noise levels.

Dermatological investigation of a hard metal factory. Part 2. Hand eczema, contact sensitisation and preventive measures
Hudundersökning vid en hårdmetallindustri - Del 2. Handeksem, kontaktsensibilisering och förebyggande åtgärder [in Swedish]
776 of 800 workers in a hard metal factory were examined. The prevalence of hand eczema was 10%. Workers who had left the industry the past 10 years and who were registered as having had hand eczema were also examined. A 10-year cumulative incidence of hand eczema was estimated at 17%. Wet grinding and oil grinding presented the highest risk of incurring hand eczema. 18% of the workers with hand eczema and 5.7% of those without, displayed positive patch test reactions. Hard metal contains about 10% cobalt. 39 workers were sensitive to cobalt. A work related hand eczema was found in 36 of these individuals. The investigation resulted in technical measures, medical supervision, health control and an educational program. The frequency of cobalt sensitization and hand eczema has declined significantly.

776 of 800 workers in a hard metal factory were dermatologically investigated. The prevalence of hand eczema and irritant reactions of the hands was 10% and 15% respectively. The cumulative incidence of hand eczema for a 10-year period was estimated to be 17%. Wet grinding and oil grinding entailed the highest risks of hand eczema. Hand eczema was significantly more common in individuals with an atopic background. The psoriasis prevalence (3.6%) was somewhat higher than expected. Even though oil mist values were well below established safety limits, acne vulgaris was more common than expected. Other skin diseases displayed the anticipated low prevalence. No cases of skin cancer were found.

The functional state of the cardiovascular system in workers adapting to exposure to occupational factors
Funkcional'noe sostojanie serdečno-sosudistoj sistemy v processe adaptacii k vozdejstviju proizvodstvennyh faktorov [in Russian]
The cardiovascular systems of 626 workers aged 20-45 and with a length of service of 10 years in the machinery industry were examined. After 2 years of employment, early cardiovascular function changes (hyperkinetic circulation, systolic hypertension, myocardial hyperdynamia) were found in workers exposed to low-intensity occupational factors (noise, vibration, chemical substances) associated with monotonous assembly-line work. After a length of service of 2-5 years, adaptation to work led to the elimination of these desorders. When the length of service exceeded 5 years, the tolerance of the heart to physical load was decreased in 52.5% of the workers, there was myocardial hypodynamia in 41%, and the mean value of dynamic pressure was increased in 30%. All these disorders may be considered as a breakdown of adaptation and a development of a pathological process.
