Development of a two-zone exhaust system for removing gases from low-capacity arc furnaces
Razrabotka processa dvuhzonnogo gazootbora dugovyh pečej maloj vmestimosti [in Russian]
When one metric ton of steel is refined in an electric arc furnace, 80-90kg of carbon monoxide, approx. 10kg fine dust, as well as sulfur monoxide, nitrogen and other substances are set free. The effectiveness of exhaust hoods rarely exceeds 70%. Description of a two-zone system which enables an effectiveness of 93-95% to be attained by exhausting 16,000-18,000m3/h (t=80°C): In the first zone, the gases are drawn from the charging door, and in the second, through the openings in the roof round the electrodes, from where the gases pass into a telescopic and articulated duct allowing the furnace to be tilted. While the gases are exhausted, air penetrates into the furnace and helps to burn part of the carbon monoxide.

Tests with devices that reduce the airflow noise produced by drop forging hammers
Ispytanija ustrojstv, snijajuščih aėrodinamičeskij šum, sozdavaemyj štampovočnym molotom [in Russian]
Results of tests carried out on sound absorbing devices of the "active" and "passive" types. During the experiments, the air pressure and impact noise level were measured at different points inside and outside enclosures made up of reinforced plastic panels lined with antidrumming compound and plastic foam (active absorption) and close to plastic screens arranged and inclined in various ways (passive absorption). According to the shape of the absorption "channel" made up by the active enclosures, the impact noise was reduced by 7 to 15dB, while the screens enabled a reduction of 9 to 14dB to be obtained.

Follow-up study on pulmonary function of dust workers: An epidemiological evaluation of discontinued workers of dust operations
An epidemiologic study on 176 workers exposed to dust in various occupations was initiated in 1978. No workers complained of chronic cough or phlegm. Their chest X-rays belonged to Category I as defined by the Pneumoconiosis Law in Japan. Pulmonary function test was performed on these workers, however, 54 workers discontinued taking part in the study by the end of 1979 ("early-discontinued" group), and 49 workers had discontinued by 1981 ("late-discontinued" group). A total of 73 workers had a 5-year follow-up survey of pulmonary function. Forced expiratory volume in 1 second divided by forced vital capacity and forced expiratory flow rate at 25% of FVC divided by height were mainly compared by smoking habit, work years, type of job, size of company, and the time when they discontinued their jobs. Predicted percentage values of lung function were used for the adjustment of the influence of workers' ages. Decrements of these values in the 5-year follow-up group were larger than the 1978 level. The mean values in the early-discontinued group were lower than in the late-discontinued and active working groups. The fact that respiratory function indicators are better for the workers with longer exposure than for the early-discontinued group is a reflection of the "healthy worker effect": only the physically healthiest workers remain in jobs that present health hazards.

Analysis of emissions collected from four types of iron casting molds
The levels of polycyclic aromatic hydrocarbons (PAH) and related compounds, phenol and particulates were determined in emissions from 4 types of binders: furan, urethane, green sand with sea coal and phenol-formaldehyde resins in shell molds. The shell sample contained 50% particulates, green sand 25%, furan 10% and urethane 2%. The portion of particulate fraction soluble in cyclohexane varied from 16 to 36% between mold types. Emissions from urethane and furan molds contained the lowest quantities of cyclohexane-soluble components and of PAH and related compounds. Phenol which was fond in all 4 foundry samples, was present in the highest concentration in emissions from urethane molds. Shell mold emissions contained the highest levels of 2- and 4-nitrophenol.

Determination of dimethylethylamine in air samples from iron foundries by isotachophoresis
Static gas standards of the amine in air were used to evaluate different sampling techniques. The collection device of choice was a midget impinger containing 10cm3 of HCl (50mmole/L). The dimethylethylamine concentration in the air of 3 different iron foundries ranged from 0.5 to 155mg/m3. No pretreatment of the samples was necessary and no interfering substances from the air in the foundries affected the analysis by isotachophoresis.

Respiratory disease in foundry workers
A survey of respiratory symptoms and ventilatory function among 46 Australian steel foundry workers exposed to moulding fumes and vapours, and of 17 after-cast workers not exposed to these substances. 11 of the exposed workers developed a wheeze while working at the foundry. Wheeze and other respiratory symptoms were attributed by the workers to substances at work, particularly phenol formaldehyde resin and hexamethylenetetramine. The evidence of ventilatory function changes was not consistent. Both irritant and hypersensitivity mechanisms seemed to be present.

Respiratory abnormalities among workers in an iron and steel foundry
A study of the health of 78 workers in an iron and steel foundry in British Columbia (Canada), and of 372 controls (workers in a railway repair yard). The foundry workers were exposed to the chemical binding system PepSet, consisting of diphenylmethane diisocyanate (MDI), phenol formaldehyde, and a catalyst containing a pyridine derivative. They were also exposed to silica particulates. The study included a questionnaire survey, chest radiography, allergy skin tests, pulmonary function tests, methacholine inhalation tests, and measurements of dust and MDI levels. The foundry workers had significantly more respiratory symptoms and significantly lower respiratory function indicators than did the controls. 3 of the workers had radiographic signs of pneumoconiosis and 12 had asthma, probably caused by sensitisation to MDI.

Proper treatment of fumes produced by die-casting machines
Dämpfe an Druckgussmaschinen richtig behandeln [in German]
Air contaminated by fumes, which are produced when die-castings are ejected and dies are lubricated, is eliminated by exhaust hoods placed above the die-casting machines and is then cleaned by filters of various kinds. The problems of condensation and of filter cleaning or changing are emphasised. A supplementary air cleaning system, based on a water curtain that retains harmful substances, is described. This system eliminates the need for long periods of maintenance and reduces fire risks. Experience with the installation and its operation is discussed.

Lung cancer mortality in a cohort of English foundry workers
A cohort of 10,250 males who began work between 1946 and 1965 in 9 English steel foundries and who worked in these foundries ≥1 year was followed prospectivley until 1978 when 1,858 deaths had occurred. Mortality from lung cancer was significantly raised among workers employed in the foundry and fettling shop areas, where standardised mortality ratios (SMR) of 142 and 173, respectively, were calculated. Most occupational categories in these 2 areas had more lung cancer deaths than expected but the SMR were greatest for the furnace bricklayers, fettlers and heat treatment furnacemen. There was some evidence of risk increasing with length of employment. Marked differences in SMR for lung cancer were found between the different foundries studied. The lung cancer risk was fairly constant by year of entry, in contrast to the improvement in mortality from diseases of the respiratory system over the same period.

Prevention of siderosis. A survey of controls in enterprises, 1971-1982
Prévention de la sidérose. Bilan des contrôles en entreprises de 1971 ŕ 1982 [in French]
More than 2000 samples were taken between 1971 and 1982 in 514 French enterprises where there was a risk of siderosis. The results of the analyses are presented by year and activity, and are related to the TLV (5mg/m3 for respirable dust and for ferric oxide). The TLV was exceeded in 29% of the cases, and in 42% of the samples connected with welding. Conclusions: prevention of siderosis must be pursued with determination; iron might constitute - in most metalworking activities - an initial "tracer" of pollution, permitting a quick evaluation of pollution in the workplace.

Bacterial and mycotic flora in the work environment of a foundry
Bakteriální a mykotická flóra v pracovním prostředí slévárny [in Czech]
In grey iron and steel foundries, an average of 93,950 microorganisms was found in 1m3 of air. Mesophilic bacteria predominated over micromycetes and actinomycetes. Microbial contamination ranged from 23,480 organisms/m3 on casting floors to 361,130 per m3 in cellars where moulding mixtures were prepared. 11 species of mesophilic bacteria and 40 species of fungi and yeasts were identified. Microbial contamination came from foundry raw materials and water, and was aggravated by insufficient ventilation. Dust (containing free Si02) that had settled on metal structures at breathing zone level contained the most varied species (8 types of mesophilic bacteria and 61 types of micromycetes). The microorganisms included saprophytic, facultatively pathogenic and toxigenic species.

The current technique of coating ingot moulds with a solution of pitch in benzene was replaced by a new process of spraying a refractory mineral dust (milled processed quartz, corundum, zirconium) in solution with colloidal silica onto the surface of the ingot moulds. The old technique gave rise to high concentrations of pitch sublimates, including benz(a)pyrene. The administration of the coating solution and resinous sublimate condensates to mice produced malignant skin tumours. The new process did not extensively contaminate the work environment. The aerosols were fibrogenic in inhalation experiments. A maximum allowable concentration of 1mg/m3 for aerosols of the colloidal silica alone and 2mg/m3 for mixtures with mineral powders of low fibrogenicity was recommended.

Vibration syndrome and vibration in pedestal grinding
After the introduction of a new type of pedestal grinding machine in a Finnish foundry, all 12 operators developed vibration-induced white finger (VWF) symptoms with an average latency period of 10.3 months. The vibration levels of the new wheels, rotating at the same speed as the old wheels, were up to 12dB higher than those of the old wheels. The vibration levels of light (0.5kg) castings were up to 25dB higher than those of heavy (5kg) castings. It is suggested that the differences in vibration levels were not sufficient in explaining the outbreak of VWF, and some other feature (such as the impulse character of the vibration) also contributed to the VWF symptoms.
