Evaluation and prevention of health hazards in curtain coating departments of furniture works
Sanitarno-himična ocenka i borba s vrednostite v lakozalivnite cehove na mebelnata promišlenost [in Bulgarian]
The authors have concluded, from their observations and theoretical calculations, that vapours emanating from freshly coated surfaces constitute the principal source of workplace styrene and toluene pollution. Reproduction of 3 formulae to determine the quantity of volatile components. The curtain dip coating machines themselves are not the main source of pollution, which is concentrated principally in the vicinity of the trolleys on which the coated elements are placed. The article recommends that coated surfaces should be dried in separate premises or in special drying rooms. This would reduce exposure to solvent vapours and improve working conditions.

Noise produced by plasma spray coating, and hygiene measures to improve the technique
Šum pri plazmennom napylenii i gigieničeskoe obosnovanie optimal'nyh tehnologičeskih režimov [in Russian]
Results of these studies: gas flow rate and composition and the nozzle diameter of the torch have a determining influence on the noise level and spectrum. Reduction of the spraying rate, inversely proportional to the cross-sectional area of the nozzle, markedly reduces the noise level. Other noise control measures: use of plasma torches in which the powder to be sprayed is introduced before reaching the anode; increasing the proportion of argon in the gas mixture; acoustic enclosure of spray-coating booths.

Behavioral effects of long-term exposure to a mixture of organic solvents
Tests for intelligence, memory, psychomotor performance and personality were made on 100 car painters and a control group. Impairments in visual and verbal intelligence, verbal memory and a reduction of emotional reactivity were ascribed to the solvent exposure. Two discriminant function analyses were also made; the sensitivity of the psychological test method was high, but the specificity was low with regard to exposure. The possible role of a potentiating effect of the solvents in the development of these disturbances is discussed.

Formation of toxic isocyanate vapours on thermal decomposition of polyurethane paints and their polyfunctional hardeners
Über die Bildung toxischer Isocyanatdämpfe bei der thermischen Zersetzung von Polyurethanlacken und ihren polyfunktionellen Härtern [in German]
A series of accidents prompted investigation of the toxicity of polyurethane (PUR) pyrolysis vapours. The chemistry of PUR paints and avoidance of poisoning by the use of diisocyanates with low vapour pressure (Desmodur), and the known facts on pyrolysis of PUR resins are first dealt with. The conditions (pyrolysis temperature of 400-600°C) and results of studies with commercial hardeners and paints are reported. In all cases diisocyanates were detected, the extent of the reformation varying considerably. The values were however considerably higher for polyisocyanates than for PUR varnishes. In the presence of PUR paints, the possibility of a hazard from thermal decomposition products should therefore always be borne in mind.

A case-referent study on neuropsychiatric disorders among workers exposed to solvents.
Published reports give justification for the belief that long-term exposure to solvents might induce chronic but non-specific neuropsychiatric conditions (disturbances in memory, emotional disorders, etc.). This case-referent study of data from a regional Swedish pension fund register indicated a risk ratio of 1.8 in regard to non-specific neuropsychiatric disorders among workers such as painters, varnishers and carpetlayers who are exposed to various solvents (turpentine and mixtures of aliphatic and aromatic hydrocarbons) as compared to workers not so exposed. Moreover a dose-response relation seems to exist between exposure in terms of years in occupation and neuropsychiatric conditions, the exposure to various solvents possibly playing an aetiological role.

Evaluation of the absorbency and permeability of chemically stable lining materials with respect to vapours of mercury and organomercury compounds
Gigieničeskaja ocenka sorbcionnyh svojstv i pronicaemosti himičeski stojkih materialov (pokrytij) k param rtuti i ee organičeskim soedinenijam [in Russian]
Results of tests showed that mercury-proof plastics are not all suitable to protect the surfaces of industrial buildings against pollution by organomercury compounds. Application of epoxy- and furane-resin-based plastic linings provides the best protection for the concrete floors of premises in which organomercury compounds are produced, processed or stored. For protection of the vertical surfaces of such premises application of 5 coats of a paint based on chlorinated polyvinyl chloride and epoxides to the rough casting is recommended.

Evaluation of health hazards in workers operating automatic varnishers exposed to toluene
Příspěvek k hodnocení pracovní problematiky při práci s toluenem u licích automatů [in Czech]
Report on observations made in 6 workers exposed to toluene while varnishing ping-pong tables with varnishing machines and in spraying booths. Toluene concentrations varied according to the type of work and location, but nearly always exceeded the MAC of 400mg/m3, with peaks of 1,020mg/m3 and even 4,328mg/m3 in drying rooms. Time measurements showed that the greatest physical effort was required of the workers in those places where toluene concentrations were highest, resulting in increased inhalation of the substance. The high level of toluene impregnation was evidenced by the equally high level of urinary benzoic acid and by typical subjective symptoms.

Chronic cyanide exposure: A clinical, radioisotope, and laboratory study.
Controlled study of 36 workers in the electroplating sections of 3 factories. Atmospheric cyanide concentrations, relative incidence of symptoms, thyroid uptake of I-131 after 4 and 24h, plasma-bound I-131 levels after 72h, and haematological findings are tabulated, and urinary thiocyanate excretion is plotted against exposure concentrations. The haemoglobin level, lymphocyte count and incidence of punctate basophilia were significantly higher in the exposed group. The presence of cyanmethamoglobin was considered pathognomonic. 24-h urinary excretion of thiocyanates amounted to 0.65mg per ppm atmospheric cyanide (mean urinary thiocyanate level in controls: 0.11mg). Thyroid enlargement was present in 20 workers, and thyroid I-131 uptakes were significantly increased. The reasons for this effect are discussed.

Pneumoconiosis in painters dealing with tonoko: three cases of "tonoko-lung".
Tonoko (78.5%SiO2, 10%Al2O3), a wood filler widely used in furniture manufacturing in Japan, has not been considered a pneumoconiosis-producing agent. Three cases of pneumoconiosis were discovered in 4 workers engaged in a furniture finishing process who had used the material daily for over ten years. Their working room environment was always dusty and tonoko was probably the main ingredient of the dust. Analysis revealed that tonoko contains about 50% quartz, and the results supported our assumption that their lung condition might be caused by tonoko inhalation.

Precautions in the use of asbestos in the construction industry.
This report by the subcommittee of the Joint Advisory Committee on Safety and Health in the Construction Industries, established by the Health and Safety at Work Act, 1974, makes the following recommendations: demolition (asbestos lagging should be removed by properly equipped specialist contractors before actual demolition is allowed to start); information (worker information on medical aspects of asbestos and on typical dust concentrations encountered in construction work; positive identification of lagging by X-ray diffraction analysis before removal; routine monitoring of airborne dust); portable power driven tools (dust control equipment); training; use of less toxic substitute materials instead of asbestos. Addresses of organisations able to provide air monitoring and analytical services, a technical data note (No.42) on probable use of asbestos-cement sheets, pipes and insulation board (information given in tabular form), addresses of suppliers of vacuum cleaning and exhaust equipment for portable power tools are appended.

Air quality control in painting shops
Luftreinhaltung in der Lackiertechnik [in German]
After an introduction on the efficient use of energy and materials in painting metallic surfaces, the author reproduces extracts of the German (Fed.Rep.) Act on pollution control (Immissionsschutzgesetz) and gives examples of measures to reduce the concentration of harmful substances in painting shops: air cleaning by filtration or water scrubbing, absorption, adsorption or solvent combustion. Advice is given principally on air cleaning in dipping and spraying shops and in drying ovens. Brief review of some painting techniques requiring less material, and thus better suited to the demands of air pollution control.

Solvent-free paints
Les peintures sans solvant. [in French]
After a review of the disadvantages of certain traditional painting processes (toxicity of solvents used, limited field of application, etc.), the author briefly describes 2 recently developed procedures requiring no solvent: water-phase electrophoretic coating (dipping method) and electrostatic spraying of plastic powders. The installations required are relatively costly, but the technical advantages and the benefits in hygiene and safety are incontrovertible.

Means of improving working conditions in the manufacture of metal-coated diamond tools
Puti ozdorovlenija truda v proizvodstve almazno-gal'vaničeskogo instrumenta [in Russian]
Results of a study of health hazards in the manufacture of electroplated diamond tools. The atmospheric pollutants at the workplace were found to include aerosols and vapours of nickel, acids (sulfuric, hydrochloric and hydrofluoric), alkalis, boron trioxide, fluorine borate, coumarine, and p-toluenesulfamide. Direct contact with aggressive products such as nickel compounds, acids, alkalis, acetone and polishing agents constitutes a further occupational hazard. Brief description of measures liable to improve working conditions: local exhaust systems, mechanisation of the nickel-plating process and of decanting of acids, enclosure, etc.

Occupational allergic skin diseases among electroplaters
O professional'nyh allergičeskih dermatozah u gal'vanostegov [in Russian]
Results of dermatological examinations carried out in 225 electroplaters with dermatitis and eczema due to solutions of chromium trioxide, ammonium bichromate and nickel sulfate, and to the chromium oxide contained in a polishing paste. A significant proportion of electroplaters' skin diseases were found to have been caused by the sensitising effects of chrome and nickel compounds and also of gold cyanates. Preventive measures are proposed (mechanisation of all manual operations, local exhaust, skin protection, utilisation of a surface-active agent in baths in order to reduce chromium trioxide evaporation, etc.).

Occupational health case report No.2 - Toluene diisocyanate.
A report of an investigation carried out by the National Institute for Occupational Safety and Health (NIOSH) regarding exposures to isocyanates, paint sprays, solvents and dust in a plant manufacturing articles made by moulding of plastics. It was concluded that under the present conditions, TDI (tolylene 2,4-diisocyanate) does not constitute a health hazard. However, symptomatic workers on the TDI line appear to be exposed to petroleum naphtha, a known irritant. It was found that the elevated environmental level of the solvent methyl ethyl ketone constitutes a borderline hazard and that no hazard exists in the paint spraying area. Recommendations are made concerning medical monitoring of workers exposed to TDI and the improvement of protective measures at the plant.

Occupational health case report No.4 - Epoxy paint.
A report of an investigation carried out by the National Institute for Occupational Safety and Health (NIOSH) at the request of an authorised representative of employees regarding potentially toxic effects from exposure to epoxy-type paint. The request was made after the majority of a 6-man paint crew experienced episodes of headache, nausea, dizziness and skin eruptions during assignments requiring the use of epoxy-type paint. It was concluded that because of inadequate protective measures, the skin ailments were caused by one or more of the components of the paint and that because of poor ventilation in confined quarters, the other symptoms were due to excessive solvent exposure.

Occupational health case report No.3 - Ethyl acrylate.
A report of an investigation carried out by the National Institute for Occupational Safety and Health (NIOSH) at the request of an authorised representative of employees concerning exposure to dust of an emulsion containing ethyl acrylate polymer at a facility manufacturing synthetic textile products. It was concluded that this dust cannot be considered inert because of its acidic character and that exposure to it at the concentrations prevailing in the plant in question constitutes a hazard. The institution of engineering improvements to control overspray and a good programme of general housekeeping would significantly reduce the hazard.
