Monitoring ventilation. Applications for painting booths
Contrôle de la ventilation. Applications aux cabines de peinture [in French]
This article discusses existing methods of monitoring (measurement of airspeed, visual observation of the state of the filters, measurement of static and differential pressures) and presents the major types of differential manometer (liquid column, diaphragm), their principles of operation and their regulation as a function of calculated changes in load. It also reviews general issues (the use of painting booths, malfunctions, regulations, standards, general principles, definition of insufficient ventilation.

Upper airway symptoms and function in wood surface coating industry workers
Respiratory and ocular symptoms were investigated in workers employed in the surface coating of wood products using either ultraviolet radiation curing (UV) or acid curing (AC). Symptoms were investigated by questionnaire and medical examination among surface coating line workers, finishing workers and a control group. Nasal, pharyngeal and ocular symptoms of discomfort were common among all exposed groups. Symptoms were most frequent in UV line workers and finishers of UV coated wood products. Mucociliary clearance was significantly slower in UV line workers. Low levels of organic solvents and coating dusts were measured in the workers' breathing zones.

Evaluation of capture efficiencies of large push-pull ventilation systems with both visual and tracer techniques
The contaminant capture efficiencies of push-pull ventilation systems fitted to twenty large open-surface metal finishing tanks were tested using videotaped smoke testing and novel tracer gas methods. Real-time infrared detection of sulfur hexafluoride tracer gas permitted convenient adjustment of air flows for optimum capture efficiency. The careful control of cross-drafts was the most significant factor for contaminant capture at tank liquid surfaces. The ventilation systems were therefore modified to reduce air flow rates and redirect air flows. These modifications also reduced noise levels and system energy requirements.

Control of paint overspray in autobody repair shops
Controls for reducing worker exposure to paint overspray were evaluated in six autobody shops and a spray-painting equipment manufacturer's test facility. Respirator usage was also studied. Of the three types of spray-painting booths studied, downdraft spray-painting booths appeared to provide the lowest worker exposure to paint overspray. Ventilated vehicle preparation stations did not control paint overspray. Switching from a conventional spray-painting gun to a high-volume low-pressure gun reduced particulate overspray exposure by 50%. Respirator usage was generally inappropriate; respirators were poorly maintained and/or did not fit. Proper use of engineering controls and respirators is recommended.

The DuPont Imron® studies: An example of possible misrepresentation of data in the industrial hygiene literature
Opinion article (not peer reviewed) commenting on a 1985 article by Vasta J.F. in the same journal ("Respirator cartridge evaluation for isocyanate containing Imron® and Cantari® enamels", see CIS 85-785). It is claimed that the original article contained intentionally misleading information suggesting that air-purifying respirators provided adequate protection against isocyanate-based paints (data suggesting the opposite are claimed having been suppressed). The manufacturer employing the researcher in question stood to gain significantly from results supporting this hypothesis. The Editor's comments preceding the article discuss the ethical issues involved. The rebuttal by Krivanek N.D. (p.826-829) defends the integrity of the original research article and its author and questions the motives of the authors of the present article.

Skin disease and contact sensitivity in house painters using water-based paints, glues and putties
A dermatological investigation of 202 Swedish construction painters included patch testing with ingredients of water-based paints, glues and putties. 48 painters had a history of eczema, of which 25 had a history of hand eczema. In 25 painters, factors in the work environment were estimated to contribute to the eczema, and in 11 of these their work was concluded to be the main cause of the disease. Allergic reactions to metals, preservatives, polymerizing agents, resins, solvents and film-forming agents are discussed. Findings indicate that construction painters do not face a high risk of skin disease.

Occupational exposure to water based paint and symptoms from the skin and eyes
Water-base paints contain organic solvents and many additives, some of them in small quantities. This complexity can lead to many new hazards in house painters, particularly of an allergic and irritative nature. This case-control study compares the health status of painters who have used water-base and oil-base paints, in order to find out if exposure to water-base paints increases the risks of mucous membrane and skin symptoms. It is shown that the introduction of water-base paints has actually improved the working environment of house painters, and that these paints cause less discomfort and airways irritation than the earlier solvent-based paints. Some dermal symptoms, however, might be due to exposure to components of water-base paints.

Perturbations of the sense of smell caused by chemicals at work
Störungen des Riechvermögens durch und für Arbeitsstoffe [in German]
The work and exposure histories and results of the medical examinations of three victims of anosmia (loss of smell) are described. The chemicals involved in causing the loss of smell were acetone, cyclohexanone, dichloromethane and tetrahydrofuran in the case of a plumber whose work involved installing and repairing plastic pipes in water treatment plants. Mixtures of organic solvents and non-occupational factors led to loss of smell in the case of a painter. Chromates or solvents were involved in the case of a worker in the chromium plating department of a shock-absorber manufacturing plant.

Neurobehavioral effects of long-term exposure to xylene and mixed organic solvents in shipyard spray painters
A cross-sectional study was performed in shipyard painters exposed to organic solvents and age-matched referents. The work duties of the painters mainly involved spray painting with solvent-based paints containing > 50% xylene. Results indicate that complaints regarding mood changes, equilibrium and fatigue were more severe in painters than in controls, but were not related to the estimated life-time exposure index. Decreased nerve function was observed in the lower extremities and to some extent in the upper extremities. The refractory period appeared to be a sensitive parameter in motor nerves. Most neurophysiological parameters investigated were significantly related to the exposure index. Behavioural testing revealed impairment of simple visuo-motor performance and complex perceptual coding. A relationship between effects on perceptual coding and the exposure index was also demonstrated.

Occupational health findings of workers exposed to organic solvents in small-sized painting enterprises
Shōkibo tosō jigyōsho ni okeru yūki yōzai toriatsukai sagyōsha no bakuro to kenkō no jittai to sono mondai ten [in Japanese]
In 41 small painting establishments in downtown Tokyo, airborne toluene levels were measured and 205 workers underwent medical examinations. (Mixed organic solvents were used at all the sites, but the major component was toluene.) Toluene concentrations in air ranged between 1 and 27ppm, while urinary hippuric acid levels were 0.04-3.44g/L (average 0.67±0.58g/L). No abnormalities attributable to solvent exposure were seen in the results of blood and urine analysis, but dermatological effects were evident: 76% of the workers had defatted skin and 17% had hardened horny layers. Some 87% of the workers used solvents to clean paint from their hands; greater use of solvents for hand cleaning was correlated with more severe dermatological effects. The habit was more common among workers less than 30 years old and in establishments with four or fewer workers.

Occupational diseases in galvanizing and electroplating plants
Berufskrankheiten in der Galvanik [in German]
Of 815 occupational diseases in galvanizing and electroplating plants reported in Germany in the period between 1982 and 1992, 92 were compensated. Almost 50% of the occupational diseases receiving compensation were skin diseases, 15% were noise-induced hearing losses and 14% were diseases caused by chromium and its compounds. It is recommended to reduce the concentrations of harmful substances by installing local exhausts and enclosures or by automation so that exposure limits are complied with. In cases where the biological threshold limits for chromium and its compounds are exceeded, medical surveillance of the exposed employees is necessary.

Prognostic value of bronchial hyperresponsiveness in car painters exposed to isocyanates
Valeur pronostique de l'hyperréactivité bronchique chez des peintres automobiles exposés aux isocyanates [in French]
Thirty five painters exposed to HDI and HDI prepolymers underwent two respiratory examinations consisting of a standardized questionnaire and measurement of pulmonary function including a methacholine challenge over a 2-year period. Non specific bronchial hyperresponsiveness (NSBH) was present initially in 11 workers and was associated with a higher tobacco consumption, a higher prevalence of respiratory symptoms and lower baseline values of lung function tests. Compared with car painters without NSBH, those with NSBH had a greater, though not significant, reduction in FEV (76mL/year versus 37mL/year). No case of asthma was diagnosed neither in car painters with NSBH, nor in those without. So, despite the weak number of patients in our study, it appears that the presence of NSBH in car painters exposed to isocyanates is not a good predictor of asthma. On the other hand, performing a test of bronchial hyperreactivity might be used as means of identifying subjects at risk for chronic obstructive pulmonary disease.

Outbreak of organising pneumonia in textile printing sprayers
Eight textile printing factories using spraying techniques in Valencia, Spain were investigated following the occurrence of severe interstitial lung disease in three employees. Clinical and radiological data and biopsy specimens from 71 (27.6%) workers with abnormal respiratory features indicated the occurrence of an outbreak of organizing pneumonia which resulted in six deaths. Although the precise toxicological mechanism is unknown, it is proposed that the lung disease was caused by spray procedures which caused inhalation of a respirable aerosol of Acramin FWN.

Mercury exposure from exterior latex paint
An investigation was conducted to determine the extent of mercury exposure from the outdoor application of exterior latex paints. Air and urinary mercury concentrations of 13 professional male painters were compared with those of 29 men having non-painter occupations. The median concentration of mercury for the four paint samples obtained was 570mg/L. The median air mercury concentration was higher for painters than for nonpainters. The median urinary mercury concentration was nearly twice as high for painters as for nonpainters. Among painters, urinary mercury concentrations increased with the percentage of time spent applying exterior paint. These data suggest increased mercury exposure among professional painters who use mercury-containing exterior paint outdoors.

Harmful substances used in painting china
Gefahrstoff-Situation beim Porzellan-Malen [in German]
Dichloromethane, turpentine, toluene and xylene are the solvents used in applying gold paint to china. The German exposure limits (MAK) for these substances are 360, 560, 380 and 440mg/m3 respectively. The biological threshold limits for dichloromethane, toluene and xylene are 2, 1.7 and 2mg/L (blood). Dichloromethane is a carcinogen. Toluene is a teratogen, xylene and turpentine are allergens. In compliance tests no concentrations in excess of the limits mentioned were found. Protective measures are outlined to keep exposure low.

Minimum ignition energy of coating powders for electrostatic coating
Die Mindestzündenergie von Pulverlacken für die elektrostatische Pulverbeschichtung [in German]
More than 40 coating powders were tested to determine their minimum ignition energies, which depend on the specific surface area of the powder calculated from the particle size distribution. In addition, the chemical composition of the powder, the amount of resin, and the tendency to agglomerate have an influence. The lowest ignition energy, 1.7mJ, was obtained for transparent epoxy coating powders with particle diameters below 25µm. There is no fire or explosion hazard with these powders if they are applied with hand-held spray guns according to EN 50050.

Paint and varnish spraying booths
Cabines de projection de peintures et vernis [in French]
A study of 34 spraying booths for liquid paint and varnishes was undertaken in France by occupational physicians to determine noise levels and ventilation speeds. The efficiency of ventilation in the booths appeared in most cases unsatisfactory and personal protective equipment worn in the booths by workers was of poor quality and inadequate. Efforts made to inform painters and enterprises, in particular to seek alternative solutions to the use of solvents for washing hands, should be furthered and intensified.

Malignant tumours of the lower urinary tract and occupational risk factors
Bösartige Tumoren der ableitenden Harnwege und Risiken am Arbeitsplatz [in German]
Chemists, chemical workers, employees in the rubber industry and hairdressers run a significantly higher risk of developing malignant tumours of the lower urinary tract. Painters were found to be at higher risk also, but not on a statistically significant level. Smoking and the consumption of beer and coffee were identified as non-occupational risk factors.

Hypersensitivity pneumonitis presenting as sarcoidosis
A case report is presented to illustrate a misdiagnosis of sarcoidosis in a spraypainter whose history was suggestive of hypersensitivity pneumonitis caused by exposure to toluene diisocyanate in the workplace. The two diseases have similar clinical, laboratory and pathological features and are thus difficult to distinguish. Since early recognition of hypersensitivity pneumonitis can lead to complete reversal of the disease in many cases, it is important to make the diagnosis as early as possible.

On the past exposure of painters to azo colorants
Zur früheren Exposition von Malern gegenüber Azofarbmitteln [in German]
Present experimental data indicate that the bladder cancer risk of painters using azo dyes depends on the kind of azo dyes used. Only bioavailable soluble azo dyes may have a carcinogenic effect. An examination of past exposures of painters to bioavailable azo dyes reveals that up to the 1950's bioavailable, soluble azo dyes including dyes based on benzidine were used for the surface treatment of wood. In those days painters had to mix and prepare the dyes from powders. Skin contact and inhalation were unavoidable. After 1960 the carcinogenic azo dyes were no longer used by painters.

Inter-rater agreement in the assessment of solvent exposure at a car assembly plant
This study investigated the feasibility and the reproducibility of a retrospective assessment of solvent exposure in the painting operations of a car assembly plant. Five industrial hygienists (the raters) reviewed summary documents on plant operations and solvent exposure levels, developed from plant records and interviews. Inter-rater agreement was evaluated by computing the percent concordance index and the intra-class correlation coefficient (r1). There was discordance among raters, a large proportion of which pertained to low exposure levels (1-5ppm). Inter-rater agreement was good for cumulative exposure scores computed for frequent exposures.

A survey of airborne HDI, HDI-based polyisocyanate and solvent concentrations in the manufacture and application of polyurethane coatings
This study summarizes the results of industrial hygiene surveys in paint manufacturing and application operations using polyurethane coatings containing hexamethylene diisocyanate (HDI) and HDI-based polyisocyanates, with some attention paid to other organic solvents. 466 samples were collected from 47 operations (mostly in application). The application surveys covered painting of transportation vehicles, large military and civilian equipment, and other industrial and construction painting jobs. The major results of these measurements show that there is some potential for isocyanate overexposure of unprotected workers and that it is greater in spray than in nonspray operations.

Absence of amosite asbestos in airway mucosa of non-smoking long-term workers with occupational exposure to asbestos
There is considerable experimental evidence that asbestos fibres are taken up by epithelial cells and that uptake of fibres is associated with various deleterious, particularly mutagenic, effects. It is not known, however, whether asbestos fibres are taken up by human bronchial epithelial cells in vivo. To investigate this question, the amosite asbestos content of the mucosa of seven different airways and four parenchymal sites supplied by these airways in six necropsy lungs from heavily exposed never-smoking long-term shipyard and insulation workers without asbestosis was examined. Amosite asbestos was readily found in moderately high concentration in all parenchymal samples, but 33 of 40 airway samples that could be evaluated showed no amosite fibres. The seven positive airways had fibre concentrations that were always much lower than the parenchymal concentrations, and these very few fibres may have been contaminants from the parenchyma. These data suggest that, at least in non-smokers, amosite asbestos either does not penetrate into or does not accumulate in human airway mucosa. These findings also call into question the idea that asbestos acts as a direct airway carcinogen in humans.

Predicting solvent concentrations from coating the inside of bulk storage tanks
A technique is presented for assessing health risks associated with coating the inside surface of a bulk storage tank. The technique uses a sequential box model to predict the time-varying solvent concentrations at arbitrary points inside the vessel during an ongoing coating process. Input parameters include volumetric flow rates of exhaust and makeup air, solvent threshold limit values and evaporation rates, and a set of exchange coefficients that characterise air circulation inside the vessel. This technique enables engineers to rate quantitatively the anticipated health risks of applying a combination of coatings. The technique also provides engineering managers a predictive tool to organise work schedules so that health and safety can become input parameters to an engineering enterprise.

A case-control study of multiple myeloma and occupation
This study investigates the relationship between multiple myeloma and employment in various occupations and industries. Interviews were obtained from 89% (692) of eligible incident cases and 83% (1683) of eligible controls. An elevated risk was observed among persons ever employed as painters [odds ratio (OR)=2.1, 95% confidence interval (CI)=1.2-3.6], particularly for those employed for 10 or more years. A small excess risk was observed among agricultural workers employed for 10 or more years, with a higher relative risk observed among farm laborers (OR=1.8, 95% CI=1.0-4.0). Among agricultural workers who reported having been highly exposed to pesticides, the OR was 5.2 (95% CI=1.6-21.1). Some evidence was also found to support an association with firefighting and employment in the petroleum- and coal-products manufacturing industries. Little evidence was found to support the previously noted association with wood exposure, and no evidence for an association with employment in the rubber or petroleum refining industries was found.

Measurement of air concentrations of volatile aerosols in paint spray applications
This study investigated whether traditional vapour sampling measures provide reliable estimates of inhalation exposure during spray painting of automobiles. Xylene and toluene were tested as representative solvents. Measured air concentrations of xylene averaged about 2ppm at base-coat paint applications and less than 1ppm at clear coat applications. Toluene concentrations averaged about 0.1ppm for both processes. Comparisons of different samplers showed that droplets produced during the spraying of both base coat and clear coat operations retain liquid solvent when the droplets reach the breathing zone of workers. The fraction of airborne solvent represented by the droplets is influenced by both the solvent vapour pressure in the mixture and the original droplet size. For the solvents and processes tested here droplets contained up to 50% of airborne solvent. The use of prefiltered charcoal sorbent tubes is recommended for monitoring worker exposure to solvents in spray application processes.

Exposure to solvents and late onset epilepsy: Two clinical cases
Esposizione a solventi ed epilessia tardiva - Due casi clinici [in Italian]
Two case-studies of late-onset epilepsy appearing in painters with heavy past exposure to organic solvents. Neither of the painters had shown any previous neurological symptoms or any other effects of exposure to solvents. Analysis of these cases and of the literature seems to support the hypothesis of a non-casual association between solvent exposure and epilepsy.

Airborne glass fiber concentrations during installation of residential insulation
In an effort to better characterise airborne fibre levels and types associated with the installation of residential insulation, airborne fibre concentrations were measured during the installation of several insulation products. Sample collection and fibre counting procedures followed NIOSH Method 7400 with some modifications. The arithmetic mean concentration of total airborne fibres during installation of batt-type insulation was 0.22f/cm3 (95% c.l.=0.18-0.27f/cm3). Significantly, approx. 20% were respirable glass fibres. For applications of blowing wool, the total airborne fibre concentrations were higher, with means of 1.0f/cm3 (0.9-1.1) or 2.1f/cm3 (1.5-2.7), depending on the product type. Glass fibres were 0.7f/cm3 (0.6-0.8) or 1.7f/cm3 (1.2-2.5) and respirable glass fibres were 0.3f/cm3 (0.2-0.4) or 0.8f/cm3 (0.5-1.3). Similar to the batt installation results, only 20-40% of the total airborne fibres were respirable glass fibres. The night after installation of the insulation was complete, the airborne fibre concentrations dropped to the levels measured before the insulation work began.

Neurobehavioral effects of long-term occupational exposure to organic solvents - Two comparable studies
Two comparable cross-sectional studies were carried out employing the same methodology but involving two separate solvent-exposed populations (N=90, N=144). In both studies, solvent-exposed workers were compared with age-matched controls on tests selected from the Neurobehavioural Evaluation System and on standardised questionnaire measures of symptomatology and psychiatric state. A similar pattern of results was obtained in the two studies indicating a significant effect on cognitive functioning, after controlling for confounding variables, occurring in those with more than 30 years of exposure. A more specific effect on learning processes was observed in those with more than 10 years of exposure. There were no indications in either study of a solvent-related increase in psychiatric symptoms.

Occupational exposure to 1,6-hexamethylene diisocyanate-based polyisocyanates in the state of Oregon, 1980-1990
Monitoring of exposure to 1,6-hexamethylene (HDI) monomers and HDI polyisocyanates from spray painting and related activities was conducted by taking 562 air samples from 60 workplaces in Oregon, USA, from 1980-1990. A high number of the samples (42%) exceeded the Oregon permissible exposure limit (PEL) of 1mg/m3 for HDI polyisocyanates. Spray finishing operations were divided into three categories: continuous industrial spraying, auto body repair shops, and intermittent spray operations of large objects. In all the surveys, the ventilation facilities and personal protective equipment were evaluated. The exposure levels were related to the HDI polymer content of the paint, types of spray guns used, ventilation facilities, and personal work practices. The impact of the Oregon PEL on the use of personal protective equipment is discussed.

Accelerated loss of lung function and alveolitis in a longitudinal study of non-smoking individuals with occupational exposure to asbestos
77 long-term asbestos workers engaged in the insulation of pipes and boilers were evaluated to quantitate annual loss of lung function. All of them had chest X-rays ≥1/0 ILO category and were life-long non-smokers or ex-smokers for > 5 years. Study parameters included pulmonary function tests and bronchoalveolar lavage for a mean of 3 visits over 30 ± 2 months. Multiple regression analysis revealed significant associations between rales or radiographic opacities and VC, FEV1, and total lung capacity; significant associations were also found between neutrophils/mL lavage fluid with FEV1 and diffusing capacity (all p<0.05). Annual declines for the asbestos-exposed were VC -92±28mL/yr and FEV1 -66±21mL/yr. Compared to other asbestos-exposed cohorts followed longitudinally, asbestos insulators with radiographs ≥1/0 and exposure ≥20 years have higher rates of FVC and FEV1 decline for both non-smokers and ex-smokers.

Assessment of occupational exposure to cadmium in the Netherlands, 1980-1989
One thousand five hundred fifty urine samples and 1,295 blood samples, collected from 919 workers, were analysed for cadmium (Cd). The workers were employed at 16 different types of workplaces. In about 7.5% of the samples, the concentration of Cd exceeded the biological limit values (CdU = 5µg/g creatinine; CdB = 5µg/L) proposed by the Dutch Expert Committee for Occupational Standards. Levels higher than these values were measured in both urine samples and blood samples of workers involved in electrochemical plating, in production of Cd stabilisers and enamels, and in soldering with silver-cadmium solder. Significantly higher concentrations of β2-microglobulin (MG) were found in urine samples with CdU >10µg/g creatinine. Cd levels in urine increased with age.

Effect of occupational exposure to cobalt blue dyes on the thyroid volume and function of female plate painters
The effect of industrial cobalt exposure on thyroid volume and function was determined for 61 female plate painters exposed to cobalt blue dyes in two Danish porcelain factories and 48 unexposed referents. Thyroid volume was determined by ultrasonography. The cobalt blue dyes were used in one of two forms, cobalt aluminate (insoluble) and cobalt-zinc silicate (semisoluble). Only the subjects exposed to semisoluble cobalt had a significantly increased urinary cobalt content (1.17µg.mmol-1 versus 0.13µg.mmol-1, p<0.0001). These subjects also had increased levels of serum thyroxine (T4) and free thyroxine (FT4I) (p=0.0001 and 0.0029, respectively) unaltered serum thyroid stimulating hormone (TSH), and marginally reduced 3,5,3'-triiodothyronine (T3), whereas thyroid volume tended to be lower (p=0.14). The group exposed to insoluble cobalt did not differ significantly in any thyroid-related parameters. No correlation between urinary cobalt and FT4I or thyroid volume was found. The study demonstrates an effect of cobalt on thyroid hormone metabolism.
