The use of isocyanate paints in auto refinishing - A survey of isocyanate exposures and related work practices in South Australia
A survey of 45 crash repair workshops where two-pack polyurethane spray paints are used has been carried out. Painters were interviewed using a combined health-work practice questionnaire. Monitoring for airborne isocyanate was undertaken in 14 spray shops. Health data from the questionnaire were compared with corresponding data for control groups of mechanics and industrial spray painters, not exposed to isocyanates. Compared with the other two groups, the isocyanate spray painters generally reported more respiratory and skin problems. Airborne isocyanate concentrations associated with various operations were monitored with both impinger and paper tape methods. A direct comparison of the two methods is presented.

Assessing exposure to solvent vapour during the application of paints, etc. - Model calculations versus common sense
Simple formulae expressing average and maximum concentrations of solvent vapour in indoor air during the application of paints, glues, and the like, have been derived using a six parameter mathematical exposure model MEM 1. The model is valid for solvents that evaporate from the liquid without fractionation and at a constant rate. Some features of the relation between exposure level and system parameters were found to be considerably more tricky than expected.

A method for characterising working environments in hot-dip galvanising
Méthode de caractérisation des ambiances de travail en galvanisation à chaud [en francés]
Although no pathological disorder has ever been reported in hot-dipping workshops in France, the thick grey-white fumes given off when pieces are dipped in the molten zinc cause concern to occupational physicians, who are not convinced that they are harmless. The main pollutants encountered in the workshops are hydrochloric acid (pickling), ammonium chloride and zinc chloride (fluxing and zinc bath), zinc and zinc oxide (zinc bath). Since zinc chloride is a greater health hazard than zinc oxide (metal fume fever), it was decided to develop a sampling method for selective determination of gaseous and particulate chlorides, ZnO and ZnCl2, ammonium chloride and the ammonia which can be released during the thermal decomposition of ammonium chloride. On the strength of tests carried out in 10 hot-dip workshops which were used as development laboratories, the following retention supports were selected: combined PVC filter + filter impregnated with sodium carbonate, for use in the vicinity of the pickling and fluxing baths or the molten zinc bath to trap ZnCl2, already used for inorganic acid sampling; a quartz fibre filter for use in the vicinity of the molten zinc bath, to trap the insoluble zinc; this type of filter is already recommended for sampling aerosols containing the salts of metals such as nickel or chromium.

Radiographically detectable lumbar degenerative changes as risk indicators of back pain - A cross-sectional epidemiologic study of concrete reinforcement workers and house painters
The subjects were 216 concrete reinforcement workers and 201 house painters. A questionnaire provided information on work history and earlier back accidents, and a standardised interview produced data on back symptoms. The occurrence of disc space narrowing, anterior and posterior spondylophytes, and end-plate sclerosis was recorded separately for each intervertebral space from lateral lumbar radiographs. Moderate to severe degenerative changes were associated with increased risk of sciatic pain but not with the occurrence of lumbago or nonspecific back pain. The different types of degenerative changes provided no further information. In a multivariate logistic regression analysis degenerative changes and earlier back accidents were significant independent predictors of sciatic pain. When these two variates were allowed for, the effect of occupation was not significant.

Isocyanate exposure and hypersensitivity pneumonitis - Report of a probable case and prevalence of specific immunoglobin G antibodies among exposed individuals
A car painter experienced three episodes of a hypersensitivity pneumonitis-like disease after exposure to two-component acrylic lacquers with hexamethylene diisocyanate (HDI) as the curing agent. High titres of HDI-specific immunoglobulin (Ig)G antibodies were found in the patient's serum by means of enzyme-linked immunosorbent assay (ELISA). In the ELISA, 5 to 10% of the sera from 455 isocyanate-exposed but asymptomatic workers were positive, depending on the criterion used for a positive test, whereas 0% of the sera from 157 unexposed referents was found to be positive. Among 10 subjects with isocyanate-induced asthma and isocyanate-specific IgE antibodies, 50% had specific IgG. It was concluded that the presence of isocyanate-specific IgG antibodies in serum is correlated with isocyanate exposure rather than with symptoms of isocyanate induced disease.

Olfactory function in painters exposed to organic solvents
The olfactory function of 54 painters exposed to organic solvents was compared with that of 42 unexposed referents. A new clinical test validated for the sense of smell was used, i.e. the University of Pennsylvania Smell Identification Test. Age, smoking habits, exposure to organic solvents, and medical disorders of importance for the sense of smell were recorded. The painters had a somewhat lower test score than the referents. However, the influence of the exposure variable was not statistically significant in a multiple regression analysis including age and smoking habits. The exposure to organic solvents was low, and therefore an effect of high exposure on olfactory function cannot be ruled out. Since some of the painters had earlier been highly exposed, the effects of high exposure are likely to be reversible.

Changes in lung function after working with the shotcrete lining method under compressed air conditions
Shotcrete techniques under compressed air are increasingly applied in the construction of tunnels. Up to now little is known about the influence of shortcrete dusts on the fuction of the lung. The lung function of 30 miners working with shotcrete under compressed air (before and after one shift) was measured. They carried personal air samplers to assess the total dust exposure. Long term effects were studied on a second group of 29 individuals exposed to shotcrete dusts and compressed air for two years. A significant increase of airway resistance and a significant decrease of some flow volume parameters were found after one workshift. These changes partially correlate close to the dust exposure. After a 2yr exposure a significant decrease of mean expiratory flow (MEF)50 and MEF25 was found. These results point to damage in the small airways and emphasise the major role of the lung functon test - including the flow-volume manoeuvre for the medical examination of the workers. Additionally, workers should carry filter masks.

Sister chromatid exchange analysis in lymphocytes of workers exposed to hexavalent chromium
To investigate the usefulness of sister chromatid exchange (SCE) analysis in lymphocytes as an indicator for mutagenic effects after in vivo exposure to hexavalent chromium (Cr), SCE frequency was analysed in lymphocytes of 44 Cr platers occupationally exposed to hexavalent Cr and 47 controls. Although urinary Cr analysis confirmed that the Cr platers were exposed to Cr, no effects of the exposure on SCE frequency were found. Smokers, both Cr platers and controls, had a significantly higher SCE frequency than non-smokers. These results suggest that SCE analysis in human lymphocytes is not a good indicator of possible mutagenic effects of exposure to hexavalent Cr.

Selenious acid poisoning in a galvanisation worker. Description of a clinical case
Intossicazione da acido selenioso in galvanica - Descrizione di un caso clinico [en italiano]
Selenium, which is an essential trace element found in many animal species and in man, is highly irritating for the skin and mucous membranes. Cases of acute intoxication have been described in man with gastrointestinal disorders and irritation of the skin and upper airways. Necrotic hepatitis and cirrhosis have also been observed in animal experiments. The paper reports the case of a galvanisation worker occupationally exposed to selenious acid, probably mainly via skin absorption, who in the space of 2 weeks developed a severe irritative dermatitis on the face and arms, accompanied by acute hepatitis with steatosis and necrosis. The skin lesions, duly treated, healed in a month, but it took over a year for the signs of cytolysis to disappear. The action of the systemic toxicity of selenium appears to be due to the fact that it interferes with essential enzymatic systems (glutathione, succinicodelydrogenase, urease, methioninadenosiltransferase), with consequent disturbance of microsomial system function and fatty acid synthesis.

Measurements of respiratory illness among construction painters
The prevalence of different measurements of respiratory illness among construction painters was examined and the relation between respiratory illness and employment as a painter assessed in a cross-sectional study of current male members of 2 local affiliates of a large international union of painters. Respiratory illness was measured by questionnaire and spirometry. Longer employment as a painter was associated with increased prevalence of chronic obstructive disease and an interactive effect was observed for smoking and duration of employment as a painter. Multiple regression analysis showed a significant association between years worked as a painter and a decrement in FEV1 equal to about 11mL for each year worked. This association was larger among painters who had smoked. The prevalance of chronic bronchitis was significantly associated with increased use of spray application methods.

The role of personal beliefs and social influences as determinants of respirator use among construction painters
The purpose of this study was to identify and rank potential determinants of respirator use among painters in the construction industry. As part of a health survey of union painters, 169 male spray painters were questioned about their own beliefs concerning the consequences of wearing cartridge respirators, as well as about the perceived attitudes of others in the workplace toward respirators. Intended respirator use was clearly associated with beliefs. The most important beliefs concerned discomfort or inconvenience. Other determinants that were associated with respirator use were respirator availability, cigarette smoking, and social influences. It was concluded that the most effective intervention strategy to increase respirator use would be multidimensional and that efforts to change only a worker's beliefs may have limited success.

Occupational dermatosis among chrome platers
Fourteen (38%) of 37 chrome platers in 17 chrome electroplating factories surveyed had occupational contact dermatitis, chrome ulcers, or both. Seven had chrome ulcers, 6 had contact dermatitis and 1 had both. Another 16 (43%) workers had scars suggestive of previous chrome ulcers. Mucosal irritation was present in 57% of the workers. The most common was throat irritation (49%) followed by nasal irritation (41%). Skin ulceration appeared to be a more specific sign of occupational dermatosis in chrome platers than dermatitis when the prevalence rates were compared to controls. Of the 7 workers with chrome ulcers, only 1 was allergic to chromate. Of the 6 workers with dermatitis, 2 were allergic to chromate and 1 to nickel. Irritant factors are therefore important in the aetiology of contact dermatitis in these chrome platers.

Malignant mesothelioma in a cohort of asbestos insulation workers: Clinical presentation, diagnosis, and cause of death
A cohort of 17,800 asbestos insulation workers in the USA and Canada was enrolled for prospective study on 1.01.67 and followed up to the present. Altogether, 356 workers had died of malignant mesothelioma by 1984; 134 of pleural and 222 of peritoneal mesothelioma. The time elapsed from onset of exposure to the development of first symptoms was longer in the group with peritoneal mesothelioma. The most effective approach to the diagnosis of malignant pleural mesothelioma was by open lung biopsy; exploratory laparotomy was the test for diagnosing peritoneal mesothelioma. Patients with pleural mesothelioma died mostly from pulmonary insufficiency whereas those with peritoneal mesothelioma succumbed after a period of pronounced wasting.

Methods for preventing emission and spreading of chromic acid mist from chromium electroplating baths
Metody zapobiegania emisji i rozprzestrzeniania się mgły kwasu chromowego z kąpieli do galwanicznego chromowania [en polonés]
Methods presented in the article fall into 2 groups: mechanical and physico-chemical. Mechanical methods include: local ventilation, use of tank covers and floats. Local ventilation is most frequently used in practice, but it is very energy-consuming. Physico-chemical methods involve the change in the qualitative and quantitative composition of chromium electroplating baths. Perfluorinated surface-active compounds may be of importance in the future due to their resistance to chromic acid at elevated temperatures.

Respiratory hazards associated with exposure to formaldehyde and solvents in acid-curing paints
Thirty-eight employees exposed to formaldehyde when working with acid-hardening lacquers and 18 nonexposed controls were examined. The mean exposure to formaldehyde during an 8-hr workday was 0.40mg/m3 air, and the mean exposure to peak values was 0.70mg/m3. Mean exposure to solvent was about 1/10 of the hygienic effect. Eye, nose, and throat irritation was more common in exposed persons than in controls. Monday morning, after two exposure-free days, forced vital capacity (FVC) values were found to have declined by 0.24L and forced expiratory volume in 1 sec (FEV1.0) by 0.21L, compared with normal values. There was a weak correlation between the individual concentration of IgG and decrease in FVC and FEV1.0. No significant changes were noted in any other lung function variable before a workshift, and no lung function changes were noted over a full workshift. Deviations in FVC and FEV1.0 values did not correlate with peak or mean exposures, or with employment time.

Exposure, lung function, and symptoms in car painters exposed to hexamethylene diisocyanate and biuret modified hexamethylene diisocyanate
The mean exposure to biuret-modified hexamethylene diisocyanate (HDI-BT) was 115µg/m3 in the air (range 10-385µg/m3), which exceeds the time-weighted Swedish threshold level of 90µg/m3. Exposure to hexamethylene diisocyanate (HDI) was about 1.0µg/m3 with brief peaks. This study investigated the effects of HDI and HDI-BT on lung function and included car platers, exposed to the same solvents and grinding dust as painters, but not to isocyanates, and car mechanics, not exposed to the agents. Car painters and platers were compared to mechanics on Monday before work. Acute effects of painting were tested by comparing the lung function values on Monday morning with those on Friday afternoon. Spirometry in painters and platers did not differ from that in mechanics. Closing volume in relation to vital capacity was increased in painters, suggestive of a "small airways disease" on Monday before work and tended to increase during a work week. Platers did not differ from mechanics.

High pressure injection injuries: A serious occupational hazard
High pressure injection equipment such as airless paint sprayers, high pressure grease guns, and fuel injection apparatus constitutes a serious safety hazard resulting in a significant morbidity. These devices deliver paint, solvents, and grease at pressures of 600-12,000psi. Substances penetrate minute skin wounds and spread widely through fascial planes and tendon sheaths, producing significant vascular compression and systemic toxicity. Of 95 suspected high pressure injection injury cases, 20 were determined to be actual injection injuries from equipment producing pressures in the range of 1,500-12,000psi. The injected substances included latex paint, mineral spirits, and concrete sealer. 14 injuries involved digits. Digital amputation was necessary in 3 patients. Hospital admissions averaged 6.5 days. Successful management of these cases involves awareness of the problem and rapid referral of the patient to an emergency department and to a competent orthopaedic or plastic surgeon.

Polymer-fume fever associated with smoking and use of a mold-release spray containing polytetrafluoroethylene
An ephemeral and debilitating flu-like illness was experienced by stamp-makers. A combination of the use of a mould-release spray containing polytetrafluoroethylene, poor general hygiene, and smoking during and after use of the spray was responsible for the workers' symptoms, commonly referred to as polymer-fume fever. Recommendations which resulted in the abatement of illness included: ventilating the vulcanising furnace, cessation of smoking in the workplace, and using a mould-release spray that does not contain fluorocarbons.

Development of a sampling and analytical method for measuring the epoxy content of aerosols: I. Development of the analytical method; II. Application of the method to epoxy-containing aerosols
A method was developed for determining the quantity of the epoxide group in pure epoxy resins, resins in partially-cured mixtures with amine curing agents, and commercial epoxy surface coatings. The method collects the aerosol in a midget impinger containing dimethylformamide, which inhibits the curing reaction between the epoxy and curing agent, preserving the unreacted epoxy functional groups present in the aerosol. It is based upon the reaction of the epoxide group with bromide in the presence of acid, with measurement of excess bromide in the reaction mixture by normal pulse polarography. The method was applied to aerosols containing mixtures of epoxy resin and amine curing agents in various degrees of cure, to aerosols containing large quantities of non-epoxy components, and to aerosols of epoxy surface coatings. The method is capable of precise and accurate measurement of epoxide functionality, and it is applicable to the measurement of epoxy-containing aerosols in spray finishing operations.

Neurobehavioural effects of occupational exposure to organic solvents among construction painters
The relationship between exposure to mixed organic solvents and changes in central nervous system function was studied in 101 construction painters. Solvent exposure was estimated using questionnaire data. Adverse effects on the central nervous system were assessed by self-reported questionnaires and 8 tests of a computer-administered neurobehavioural evaluation system. The results were both biologically plausible and in agreement with other empirical evidence. A consistent positive association was observed between most measures of exposure and the occurrence of neurotoxic symptoms, notably dizziness, nausea, fatigue, problems with arm strength, and feelings of getting "high" from chemicals at work. Associations with exposure were found with the neurobehavioural evaluation system tests of symbol digit substitution and digit span; however, no consistent effect on neurobehavioural function was observed. This pattern of the occurrence of neurotoxic symptoms without clear evidence of function deficit is consistent with the type I toxic central nervous system disorder as classified by the World Health Organisation.

A mortality study of nickel/chromium platers
A cohort of 2,689 nicel/chromium platers between 1946 and 1983 was studied. All members of the cohort had some period of chrome exposed employment. Overall, compared with the general population of England and Wales, statistically significant differences relating to cancer were found for cancer of the stomach, primary cancer of the liver, cancer of the nose and nasal cavities, cancers of the lung and bronchus, and all cancers. Chrome bath workers are the more heavily exposed workers, and a striking difference in SMRs was found for lung cancer among men first employed as chrome bath workers and men first employed as other chrome workers. Significant positive associations were found only for cancers of the lung and bronchus and duration of chrome bath work. Exposure to nickel was an important confounding exposure.

Contact allergy caused by metal sprays
Report of a case of a worker who coated pipes with synthetic rubber. He shoed no reaction to rubber or rubber chemicals in patch tests, but showed strong positive reactions to nickel and chromium. Investigation showed that he worked near 2 metal spraying areas where airborne nickel levels were 4 times higher and chromium up to 18 times higher than the UK Health and Safety Executive recommended maximum time-weighted averages. Recognised risks of metal spraying include dust, explosion and fume fever; nickel or chrome allergy has not been recognised previously.

Prevalence of occupational asthma in spray painters exposed to several types of isocyanates, including polymethylene polyphenylisocyanate
The prevalence of occupational asthma was assessed in 4 paint shops of a large assembly plant where 51 employees were exposed to several types of isocyanates, including polymethylene polyphenylisocyanate (PPI). Three employees were first referred by their physician for asthma symptoms. A questionnaire was administered to the other 48 employees. Seven of these were suspected of having work-related asthma. Airway hyperexcitability to inhaled histamine was demonstrated in these 10 subjects (3 referred and 7 screened). The diagnosis of occupational asthma was confirmed in 6 subjects (3 referred and 3 screened) through specific inhalation challenges in the laboratory to a paint system component containing PPI. Thus, the prevalence of occupational asthma was 11.8% in these paint shops using several types of isocyanates, including PPI.

Determinants of respiratory symptoms in insulation workers exposed to asbestos and synthetic mineral fibres
Responses to a mailed respiratory symptom questionnaire from 537 insulation workers without diagnosed asbestosis were analysed by logistic regression. Wheezing complaints and breathlessness were related primarily to current cigarette smoking and to symptoms suggesting an asthmatic predisposition antedating work in the trade. There was also evidence that these complaints were related to occupational exposure in subjects with prior airways hyperreactivity. An asthmatic predisposition antedating work in the trade was the major determinant of acute respiratory symptoms in the workplace. The effects of workplace exposures on respiratory symptoms may have been underestimated due to selective withdrawal from the active workforce and due to inaccuracies in the measure of exposure used.

Risk of developing diseases with temporary disability in workers in electroplating shops
Risk vozniknovenija zabolevanij s vremennoj utratoj trudosposobnosti u lic rabotajuščih v gal'vaničeskih cehah [en ruso]
Working conditions and morbidity rates of workers in electroplating shops at instrument-making plants were studied. Morbidity rates for most diseases are higher among women than among men. Diseases of the respiratory, circulatory and musculo-skeletal systems, and inflammation of the skin and subcutaneous tissue were prevalent. The length of service and, particularly, the patient's age had the greatest impact on morbidity with temporary disability. A high incidence of diseases was observed in workers in the main and auxiliary occupations, a low one in workers engaged in maintenance work.

Health hazards in chrome plating work
Hälsorisker i förkromningsarbete [en sueco]
Report on a study of exposure conditions in the Swedish chrome plating industry and a clinical examination of the impact of exposure on airways, pulmonary and renal function. A cohort study of cancer mortality in chrome plating workers and spray painters who had used paint containing lead chromate and zinc chromate was also made. Correlations found between different levels of mean daily airborne exposure, expressed in µg of Cr(VI)/m3 and complaints/examination findings in the airways are presented (nasal irritation, atrophy of septal mucosa, ulceration of the nasal septum, impairment of pulmonary function). A comparison with the national average showed that cancer mortality in cohorts was in close agreement with the expected figure. However, cancer deaths concentrated in groups with long-term exposure to high concentrations of chromates.
