Release of chromium and nickel aerosols during metal spraying
Krom- och nickelemission vid termisk sprutning [in Swedish]
Various methods were used to analyse the particulate air pollution produced by 5 different metal spraying techniques. The metal fumes showed considerable differences with regard to Cr and Ni content, particle size distribution and valence of Cr according to the metallising technique used. Common features of all techniques were that a large proportion of the aerosols consisted of particles smaller than 1µm, and that the particles contain hexavalent Cr. The possibility of using the urine Cr level as an exposure test has also been investigated and should be confirmed by further research.

A cohort study of disability pension and death among painters with special regard disabling presenile dementia as an occupational disease.
2601 painters and 1790 bricklayers (not exposed to organic solvents) were followed for 5 years. Compared with the bricklayers and a control group from the general Copenhagen population, painters had a relative risk of approx. 3.5 of being awarded a disability pension due to cryptogenic presenile dementia. There was no excess risk for other neuropsychiatric diseases.

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.

Prediction of concentrations of solvent vapours emitted during painting and varnishing work
Metoda prognozowania wskaźników emisji w procesach malarskich i lakierniczych [in Polish]
Empirical formulae are presented permitting prediction of solvent concentrations at the design stage of painting and varnishing processes. The regression equations are based on experimental data from correlation analysis between the emission and the time, temperature, airflow rate and thickness of the paint layer applied, and on 2 constants: 1.5g/dm2 for the layer and 15min for the duration of emanation. The formulae can be used to determine the maximum quantities of solvent liable to be released from 1dm2 painted or varnished surface, as a function of temperature and airflow. Prior classification of paints and varnishes into 3 categories according to the nature of the solvent they contain enhances reproducibility of the formulae.

Exposure to organic solvents - A cross-sectional epidemiologic investigation on occupationally exposed car and industrial spray painters with special reference to the nervous system.
80 spray painters with long-term low-level exposure were compared with 2 reference groups of 80 controls. Studies included psychiatric interviews, psychometric tests, neurological, neurophysiological and ophthalmological examination, and computed tomography of the brain. There were statistically significant differences between exposed workers and controls for psychiatric items relating to neurathenic syndrome and psychometric tests (reaction time, manual dexterity, perceptual speed, short-term memory). Most neurophysiological parameters measuring peripheral functions showed significant differences. Some differences were found in the results of ophthalmological examination and computed tomography. Exposure levels were well below Swedish exposure limits.

Occupational nickel dermatitis in the electroforming industry.
A major outbreak of nickel dermatitis in men working in an electroforming plant where complete automation is difficult to achieve is reported. Patch tests confirmed nickel allergy in 13 of 27 workers. Nickel chloride was a more reliable patch test allergen than the sulfate or sulfamate. There was an immediate decrease in the incidence of dermatitis when measures to reduce exposure were implemented: removal of workers from the electroforming process until their skin was clear; use of long-sleeved overalls and PVC gloves; washing of skin contaminated with process chemicals; wearing of safety glasses; patch testing of recruits; limitation of the duration of continuous shifts at the parting station to 4h.

Use of shotcreting machines
Einsatz von Spritzbetonmaschinen [in German]
The hazards of dry shotcreting equipment and installations and their safety features are dealt with. The chief problem is exposure to cement dust and caustic additives, which cause irritation and a reduction in visibility, with an attendant accident hazard. Methods of wetting the dry mixture are presented. A common cause of accidents is rebounding of mixture particles from the wall: personal protective equipment cannot always be relied on here. Technical solutions to problems of prevention are reviewed, including a remote-controlled system for the spray nozzle. Determination of the initial strength of the concrete is also dealt with.

Symptoms of car painters with long-term exposure to a mixture of organic solvents.
Early symptoms of the effects of low-level exposure were studied by symptom questionnaire in 102 car painters and 102 controls. Exposure was about one-third of the Finnish TLV. Fatigue and memory and vigilance disturbances occurred significantly more often in the exposed workers. Acute irritation and "prenarcotic" symptoms during the workshift were significantly more common. Health had been an important reason for having left the trade in 124 men who had changed employment in the 5 years before the study; the study subjects may therefore have undergone some degree of health selection. The questionnaire study is a useful method of detecting early effects of exposure to organic solvents.

Paint spray tests for respirators: Aerosol characteristics.
A technique to control aerosol concentrations for testing paint spray respirators is described. Details are given of the liquids used, atomising nozzle, control of liquid flow and dilutent airflow, and concentration measurements. Particle-size distributions of lacquer and enamel were measured. The lacquer distribution was multi-modal. The results of filter performance tests with 2 types of approved filter are given. Filter loading resistance was significantly affected by variations in aerosol concentration. The lacquer and enamel tests are not ideal as standard aerosol test methods. The reliability of these methods can be improved by modifying the current NIOSH criteria to include a description of particle-size distribution, more precise definition of the paint and thinner compositions, and a narrower concentration range.

Mortality among workers in the metal polishing and plating industry, 1951-1969.
Polishing, electroplating and coating metals involve hazardous exposure to metals such as chromium, nickel, copper, iron, lead, and zinc, corrosive acid and caustic alkaline solutions, and to solvents such as trichloroethylene and tetrachloroethylene. Data from death certificates of 1292 white workers from all over the USA were compared with the general white population. There was a high proportion of deaths due to cancer of the oesophagus and liver, especially in workers over 65 years. It appears that metal polishers and platers are subject to carcinogenic exposures.

Cancer mortality among workers exposed to zinc chromate paints.
250 painters at 2 aircraft maintenance bases were studied since 1959. There was a significant excess of cancer, primarily of the respiratory tract, in the 202 deaths among spray painters, and no excess of cancer in the 48 deaths among electropainters not exposed to chromate. The relative increase of respiratory cancer correlated with estimated exposure time, and was confined to painters whose interval from first employment to death was at least 20 years. The findings are consistent with occupational exposure to chromium compounds, but other factors may be operative.

Ship painting - Exposure to solvents and paint mist
Fartygsmålning - Exposition för lösningsmedel och färgdamm [in Swedish]
Research report on health hazards of painting in the ship-building industry in Sweden. Solvent concentrations of 15-50% are found, and 30% is a normal value; higher concentrations are present in enclosed spaces. Additive effects exceeding the TLV by a factor of 15 have been recorded. Median exposure during 17 man-days of spray painting in a shipyard exceeded the TLV by a factor of 4.5. Considerations on use of respiratory protection. Paper masks sometimes used only collect and store solvent aerosols. 500-2500mg of xylene can be absorbed in one day of spray painting, resulting in reduction of short-time memory and increase in reaction time. Samples of alveolar air were taken, showing concentrations of 150-175mg/m3 xylene in some cases. Physical workloads demand respiration rates of 25-35l/air/min. During a 30h period of spray painting an average exposure rate of 27mg/m3 paint dust was found.

Elimination of health hazards associated with hot-dip galvanising and hot-dip coating with tin, lead and aluminium
Åtgärder mot hälsorisker vid varmförzinkning och varmdoppning i tenn, bly och aluminium [in Swedish]
Galvanising is the method most discussed in this report. The most important air pollution is flux fume. Air pollution occurs at different stages of the production process such as dipping the workpieces into the molten metal, dosing of fluxes, centrifuging, and work with flux and drosses. Pollutants are spread by warm air currents. Fume from the zinc bath contains components such as zinc chloride (considered to be the major health hazard). Methods for eliminating or reducing flux fume are considered: adding flux in small quantities; reducing surface area covered by flux; avoid disturbing the flux layer; local exhaust ventilation. Health hazard prevention methods are the same for hot-dip coating with tin and lead. Regular workplace-air sampling and analysis is necessary; the report describes the development and testing of a sampling and analysis method for zinc compounds.

Problems considered: processes using cyanide zinc plating baths; 3 alternative cyanide-free plating processes (alkaline non-cyanide, neutral, and weak acid); hydrogen cyanide emission from plating baths; handling of cyanide salts; possible inhalation of cyanide dust when adding cyanides to plating baths. Preventive measures: reduction of cyanide content of plating bath; rim exhaust slots; personal protection. As regards cadmium, this health hazardous metal can often be replaced by Zn; use of Cd in surface treatment will probably be prohibited in Sweden in future.

The effects of isocyanates, especially hexamethylene diisocyanate (HDI), were studied in car painters, sheet-metal workers (exposed to solvents, but not HDI), and car mechanics (no exposures). The results of lung function studies (spirometry and nitrogen washout) on Monday morning were compared with those on Friday afternoon. Closing volume was increased in HDI-exposed workers, and tended to increase over the working week. The nitrogen washout method indicates small airways effects before they are discernible by spirometry.

Studies on the health hazards of lead in "Kutani-Yaki" ceramics painters
Studies were done in 181 ceramics painters (105 men and 76 women). The blood lead level (PbB) was 5-50µg/dl and the urinary lead level (PbU) 10-200µg/l. ALAD and free erythrocyte protoporphyrin (FEP) correlated with PbB, but urinary ALA and coproporphyrin did not, nor with PbU. Haemoglobin, red blood cell count, haematocrit and blood specific gravity showed no correlation with PbB or PbU. Women workers with a PbB above 20µg/dl had more subjective complaints, and those with a PbU above 60µg/l had more histories of abortion.

Neutralisation of gaseous effluents in paint shops
Obezvreživanie ventiljacionnyh vybrosov pokrasočnyh učastkov [in Russian]
Description of some methods for the elimination of organic substances (in particular solvents) contained in these effluents: low-temperature catalytic combustion, high-temperature post-combustion and adsorption on activated carbon, followed by thermal desorption and post-combustion. An economic advantage of post-combustion lies in the fact that existing industrial furnaces can be used.

Exposure of paintworkers in the motor car industry to organic solvents, dusts and metals - Comparison with working conditions of other workers
Billackerares exposition för organiska lösningsmedel, damm och metaller - en studie med avseende på tidigare arbetsmiljöförhållanden [in Swedish]
Description and results of an industrial health survey to evaluate present-day exposure of these workers, as compared to conditions found in painting shops in the 1950s. The authors studied working methods, products used, and ventilation conditions. Numerous air samples were taken at different workposts and by monitoring devices on the workers themselves during grinding, masking, puttying, spray painting etc. The results showed that painting methods had changed considerably since the 1950s: use of products based on polyacrylates, epoxy resins and polyesters; more efficient ventilation and sanding systems; use of personal protective equipment and replacement of benzene by less harmful solvents. There is less exposure of painters to metal dust and pigments, but exposure to solvents has remained the same (except for benzene).

Colour finishing of metals - Poisoning hazards
Coloration des métaux - Risques d'intoxication. [in French]
As a result of a serious case of arsine poisoning in workers employed in dipping metal products in vats containing arsenic and copper salts, to give them finish resembling antique pewter, the French National Research and Safety Institute (INRS) analysed a number of blueing and metal colour-finishing preparations available commercially. The As, Se, Sb, Cu, Hg and Zn content of these preparations is shown in tabular form. This report lists succinctly a number of colour finishing processes, indicating the toxic substances used. Recommendation: the composition and degree of toxicity of the preparation should be clearly indicated on the label and in the instructions for use; the finished product should be coated to prevent the deposited toxic colouring agent from rubbing off; elimination of toxic residues from metal finishing baths.

Benzene exposure in the rubber coating industry - A follow-up.
This paper is a follow-up of a study published in 1961 (CIS 870-1962,Dafb Fum Xjy). 38 workers exposed for 1-24 years to 5-50ppm (peak 140ppm in one case) benzene until 1964 were studied. There was one case of mild benzene poisoning (exposure 40ppm) and a small number of blood changes, but no blood dyscrasias or leukaemia. The current ACGIH threshold limit value of 10ppm appears reasonable.

Urinary and plasma concentrations of nickel as indicators of exposure to nickel in an electroplating shop.
Urinary and plasma nickel concentrations were monitored for a week in 4 workers, along with nickel concentrations in the environmental air. Workroom air concentrations were 0.03-0.16mg/m3 nickel, mostly as soluble nickel sulfate. Urinary and plasma nickel were higher after the workshift than before, and correlated with air nickel concentrations and one another. Plasma and urinary nickel concentrations may be used as biological indicators of exposure to soluble nickel compounds.

Hazards of spraying with two-pack paints containing isocyanates.
The spray from these paints consists partly of isocyanate in liquid form, and partly of particles of the prepolymer, with isocyanate droplets adhering to them. 6 case histories of paint sprayers allergic to isocyanates are given, illustrating the lack of information provided by manufacturers and of precautions taken. Recommendations made included: spraying only in booths or enclosures with effective exhaust ventilation; use of airline breathing apparatus; exclusion of workers with a history of respiratory allergy; mention of the isocyanate ingredient on the label.
