Hazards linked to the manipulation of carcinogens - A. Principal carcinogenic (or potentially carcinogenic) substances used in laboratories
Risques liés à la manipulation des produits cancérogènes. A. Principaux produits cancérogènes (ou potentiellement cancérogènes) utilisés dans les laboratoires [in French]
A survey of carcinogens (defined as substances having mutagenic as well as cancer-promoting effects) - schematic diagrams, identification methods of chemical carcinogens (epidemiological studies, animal experiments, quick detection methods), classification of carcinogens. Review of the principal families of carcinogenic compounds: aromatic hydrocarbons, halogenated derivatives, heterocyclic compounds with 3 atoms, aromatic amines, hydrazins and their derivatives, N-nitroso derivatives, alkyl sulfates, alkyl sulfonates, inorganic compounds. The possible relation between chemical structure and carcinogenicity is studied. This relation must be considered when evaluating the health risks involved in the manipulation of chemical substances, and when implementing preventive measures.

Measurement and evaluation of coalmine dust in terms of its pathological effects
Wirkungsbezogene Messung und Bewertung des Staubes im Steinkohlenbergbau [in German]
In the 1950s, dust exposure levels for mines were determined on the basis of the statistical properties of dusts and their relation to length of exposure and pulmonary changes. Further studies along these lines have concerned the effect of dust particle size on the inhalation of dust and its deposition in the respiratory tract. The properties of gravimetric dust samplers correspond only partly to the process of alveolar deposition. Epidemiological studies have not yet provided measurements to prove that quartz in mine dust has a determining role in the development of pneumoconiosis. Biological studies of the effect of quartz show that the specific deleterious effects of mine dusts should be evaluated in terms of the "free" surface of a given dust and not in terms of gravimetric/granulometric parameters.

The management of risk: Application to the welding industry
Assessment and management of health risk in the welding industry involves an understanding of the societal and human costs of accidents, which tend to occur early in working experience, and the health effects of exposure to fumes and gases which can contribute to a reduction in quality of life. In the light of present knowledge, ranking of potential risk is difficult but situations, individuals and combinations of circumstances which can lead to excess occupational health risk can be identified.

Wilson R., Crouch E.
The problems inherent in defining, perceiving and estimating risk are discussed to provide guidance in risk analysis. Theoretical discussions are combined with actual analysis, in risk-benefit terms, of cases involving saccharin, nuclear power plants, automobile safety, radiation exposure, nuclear copper mining, mass chest radiography, skull fracture diagnosis, coronary artery surgery, and swine influenza immunisation. Risk assessment is a technical function requiring statistical analysis of data and should be separate from decision making on policy issues.

Strategies for controlling hazards at work
A framework is proposed in which the potential for loss or harm at work can be recognised and strategies developed for hazard control and prevention. Intervention for hazard control consists of anticipation and reaction. Anticipation strategies include elimination of the source of the hazard, containment of the risk of its realisation, and mitigation of the likely consequences. Decisions about strategies depend on the organisational context and varying interests. The development, implementation and monitoring of any strategies that are decided upon are then discussed including the fact that such actions and events may not produce the intended results. Appropriate adaptations must be made on the basis of the evaluation of data provided by monitoring procedures.

Methodology for an occupational risk assessment: an evaluation of four processes for the fabrication of photovoltaic cells
Using data from the California semi-conductor industry, a 5-step occupational risk assessment procedure was applied to 4 processes for the fabrication of photovoltaic cells, which represent an emerging technology, and for which occupational hazard data do not yet exist. These 5 steps are: identification of process operations within a process; identification of occupations involved with each process operation; calculation of the labour requirement for each occupation to complete a given process operation; calculation of disability and mortality rates and application of them to labour requirements; summation of all occupational disability and mortality values by individual operation and by fabrication process. Estimates of disability and mortality rates for this emerging industry, based on the theoretical procedure, were higher than those calculated for the semi-conductor industry due to higher risks associated with the silicon I and gallium arsenide processes.

Estimating the safety of power supplies for mines
Ocenka bezopasnosti sistem ėlektrosnabženija šaht [in Russian]
A probabilistic risk-assessment model was used to compare 3 ways of providing a mine with electric power: via conventional lines from a local substation, via underground lines or via isolating transformers. Calculation of the probabilities of electric injuries to workers, fires and ignition of methane-air mixtures showed the system with isolating transformers to be the safest.

Predicting the fibrogenicity of silica-containing dusts from the surface properties of the particles
Prognozirovanie stepeni fibrogennosti kremnezemsoderžaščih pylej v zavisimosti ot svojstv poverhnosti častic [in Russian]
The severity of pneumoconiosis induced in rats by 5 silica-containing dusts was correlated with their adsorptive capacity and zeta-potential. DQ-12 quartz (a common reference material) and Ljubercy silica, with zeta-potentials greater than 20, gave much higher lung dry weights and hydroxyproline and lipid contents than did Ky¿tym, Vodolak, or Onega silicas, which have zeta-potentials of 8 to 13; the latter silicas were still fibrogenic in comparison with controls. The more fibrogenic silicas likewise had higher adsorptive capacities for calcium ions and dichlorodimethylsilane. These physico-chemical properties thus provide a quantitative scale for predicting the risk associated with the mining and handling of silica-containing dusts or powders.

A prospective method for estimating occupational health risks in new energy technologies
The approach used (and illustrated by application to the photovoltaics industry) is to separate out the workforce of an emerging industry by different worker classifications, and to determine the health risks to these workers from statistics of related industries. The approach identifies accident-related effects, but cannot be used to quantitate occupationally induced disease.

Studies on the importance of noise relative to other occupational stress factors
Untersuchungen zur Wertigkeit des Lärms im Vergleich zu anderen Belastungsfaktoren am Arbeitsplatz [in German]
Following a number of pages on examinations and studies on 40 persons with or without hearing loss, a report is given of field trials on 314 workers from different branches of industry (miners, loggers using chain saws, chemical workers, metal machiners, technicians testing compressors, mechanical engineering draughtsmen, arc-air gougers). In most types of work, noise is not the sole stress factor. Hearing acuity is a major determinant in vegetative reactions to noise. The number of years of exposure is a parameter of less importance to health than other factors. The finger pulse amplitude curve is a good indicator or reaction to noise: a normal curve indicates a healthy reaction, an abnormal curve demonstrates health impairment.

Application of rat mast cell incubates as a possible short-time test for sensitizing occupational chemicals
The direct action of sensitising chemicals (formaldehyde, phenol, phenylhydrazine, p-aminophenol) on rat mast cells was investigated by determination of histamine, using HPLC separation and fluorimetric detection. Dispensed mast cells from immunised and non-immunised Wistar rats are more sensitive than small-cut lung tissue slices. Passive cutaneous anaphylaxis was negative after a fortnigh's sensitising experiment using the same sensitising agents. Short-time tests with rat mast cells reflect anaphylactoid response and are suitable for the screening of sensitising chemicals.

Risk assessment for the welding industry
Part I, introduction to risk assessment, deals with the problems of quantitative assessment of the health risk, and reviews the literature on the occupational cancer risk in general and the specific risk of lung cancer for welders (chromium and nickel exposure in stainless and high alloy steel welding). Part II, process-dependent risk of delayed health effects for welders, studies the distribution of welding fume exposure, the incidence of pneumoconiosis and siderosis, and the possible cancer risk for welders. An attempt is made to develop a model for quantitative risk assessment (on the basis of dose-incidence data). Analysis of the literature on the usefulness of screening tests for mutagenesis and carcinogenesis shows that the risk for genetic damage and other delayed health effects to welders is similar to that found in other industries with Ni and Cr(VI) exposure.

Physical working conditions: the workers' point of view
Les aspects matériels des conditions de travail: le point de vue des salariés [in French]
Survey of 300 workers in a plant, under the supervision of a tripartite committee in which all grades of workers and all the trade unions were represented. Workers seem much less concerned about physical working conditions than do their representatives or experts from outside the plant. Three factors contribute to the workers' recognition of a hazard: clear perception of harmfulness; lack of comprehension of the hazardous factor's mode of action; the fact of being submitted to the harmful action of a factor not directly related to the worker's own job.

Attempt to assess the subjective severity of industrial accidents - Application in two environments at different industrial development levels
Essai d'appréciation de la gravité subjective des accidents du travail - Application dans deux milieux différents selon le niveau de développement industriel [in French]
Using an psychometric function relating objective values to those obtained by Thurstone's successive-intervals method, it was possible to assess the negative utilities attached to physical injury resulting from occupational accidents. The results suggest that subjective values associated with health and physical integrity may differ depending on the degree of industrialisation and economic development, and that the use of methods such as these makes it possible to assess the parameters of the function that characterises this development.

Risk assessment in the welding industry: Part 1 - Introduction to risk assessment
The concept of risk assessment and the difficulties inherent in quantitative assessment of the health risks suffered by welders are discussed in the context of existing studies and literature. Some epidemiologic studies have shown an excess risk of lung cancer for welders. The carcinogenic potential of nickel and hexavalent chromium in fumes from stainless steel welding processes, and the implications of positive results of short-term in-vitro screening tests on this class of fumes, are discussed.

Detection and prevention of rockburst hazards
Erkennen und Bekämpfen von Gebirgsschlaggefahren [in German]
Introductory survey of the state of the art and conditions preceding the occurrence of rockbursts. There are still a great many unresolved questions, but some methods for detection and prevention of these occurrences have been successful in practice. Among the principal methods of detection, this article describes methods of sounding rock by drilling and seismic acoustics. Three techniques for relieving tension have proved efficacious: relief drilling, relief blasting and water infusion; but confirmation of the efficacy of relieving methods is still required. Future prospects of improving these methods.

Developing opportunities for research in occupational medicine.
Examples illustrating the need for ongoing research if successful conclusions are to be reached about the effects of work on health, are drawn from recent research programmes conducted in the rubber industry. Detailed fact finding, with recognition of the principles of the dilution of risk, latency in disease onset (especially for cancer), accurate follow-up of leads, and location of risk areas, are all pertinent research pathways which can contribute to the prevention of work-related diseases.

"Qualimetric" evaluation of the safety of work plant and procedures
Qualimetrische Bewertung der Unfallsicherheit von Arbeitsmitteln, Arbeitsverfahren und Arbeitsstätten [in German]
Subjective verbal evaluations of the safety of the work situation are not always satisfactory and should be replaced by quantitative and objective methods. Description of a "qualimetric" method, i.e. based on quantifiable and non-quantifiable parameters, using the criterion of accident probability combined with severity coefficients for assessing the consequences of the accident. Specimen evaluation for multispindle bar-chucking automatic lathes and mathematical calculation.

Hazard level determination method
Metoda određivanja stupnja opasnosti [in Serbocroatian]
Abridged text of M.D. thesis. One of the possible ways of hazard level determination in building construction is measuring and ascertaining the hazard frequency, the duration of the hazard and its numerically expressed magnitude. This method is based on 3 years research and measurement results. Three types of multistorey construction techniques are compared in the light of the figures obtained. The method enables optimal safety measures to be planned and an appropriate safety policy to be adopted.

Quantitative risk analysis in the chemical industry
Quantitative Risikoanalysen in der chemischen Industrie [in German]
Deals only with quantitative determination of rates of event occurrence using logic diagrams (fault trees) and not with the quantitative determination of damage. Following explanation of the structure of the logic diagram and the principle of quantitative analysis, the importance of 3 critical aspects is studied: maintenance; quality of data input; predictive potential of weak-point analysis. The application of these principles is demonstrated using 3 practical exemples: storage tank for hydrochloric acid; phosgene reactor; ethylene transfer installation for an intermediary storage tank. The most serious criticism concerns the reliability of the input data which are often lacking a sound statistical basis. Recommendations for fault-tree analysis in the chemical industry.

Hazard detection by illness pattern similitaries
Summary data for about 120,000 episodes of employee absence of > 3 days, due to illness or accident, in a North-Eastern U.S. chemical corporation were analysed using a clustering procedure programmed for epidemiological use. The diagnoses for the absences, which occured between 1959 and 1967, were coded according to 8th revision of the International Classification of Diseases. Comparisons were made of similarity or dissimilarity of illness patterns among salaried and hourly paid men and women workers in 11 age-groups and different job groups. Patterns were obtained for the 9 illness diagnoses which accounted for 60% of reported illness. The analysis suggested the criterion: an environmental exposure of people associated with an illness pattern typical of a more advanced age is a health hazard.

Test methods for the safe control of chemical reactions
Prüfmethoden zur sicheren Führung chemischer Reaktionen [in German]
Adequate evaluation of the thermal-explosion hazard of a chemical reaction is not feasible since general rules and guidelines cannot be established. Reviewed are test methods devised by the Federal Institute of Materials Testing and the chemical industry in the Federal Republic of Germany to collect data to evaluate the explosion hazard and draw up measures to monitor chemical processes in industry. The test methods cover: combustibility, ignition temperature, explosivity characteristics, exothermic reactions, spontaneous combustion, energy consumption and release, spontaneous heating, amount of heat released by a reaction and reaction duration. Illustrated description of the test apparatus. A French translation (partial) may be obtained from INRS, 30 rue Olivier-Noyer, 75680 Paris Cedex 14, France.
