Mortality by cause among stationary engineers and stationary firemen.
Stationary engineers operate and maintain equipment for power generation, heating, etc., while stationary firemen (boiler firemen) are mainly involved in operation and maintenance of steam boilers. Causes of death of 1,113 such workers were analysed. Deaths from cancer of the buccal cavity and pharynx and cancer of the rectum were twice as common as predicted, and lung cancer deaths 20% higher than predicted. Mortality from coronary heart disease was high. The relations between these findings and substances to which the workers are exposed are discussed.

Technical measures for protection against hearing damage
Prevención técnica del trauma sonoro [in Spanish]
A brief analysis of the Spanish regulations, 1949, concerning electric power stations (which fix, inter alia, a maximum permissible sound pressure level of 60dB for generating plant) and the Occupational Safety and Health Ordinance, 1971, is followed by critical comments on the law in force at present, especially with regard to mandatory requirements and conditions for noise level measurement and the measuring methods prescribed, which the author critically compares with more recent criteria (ISO international standard R/1899 and the United States Occupational Safety and Health Act, 1970). Various practical solutions to noise control problems in existing power stations are proposed: personal protective equipment (hearing protectors), compliance with hearing protection standards, job rotation for workers in posts involving exposure to noise) and in projects for future power stations (safety by design). Detailed tables give the maximum allowable sound pressure levels for rotating electrical machines.

Fever of undertermined etiology after cleaning of steam turbine condensers.
Two outbreaks of a febrile syndrome marked by chills, headache, myalgia, nausea, and malaise occurred in workers who had cleaned the steam condensers of electric power turbines. Mean incubation period was 38h. 22 of 23 exposed men became ill. Clinical and environmental investigation failed to reveal the aetiology of the outbreaks. The circumstances and clinical syndrome have points of similarity to fever following inhalation of metal fumes and certain cotton dusts, and to Pontiac fever. It is thought that the symptoms were caused by inhalation of an unidentified toxin-producing microorganism.

Audiometric and audiologic services for noise exposed workers.
Over 12,000 employees involved in production and distribution of electric power, gas and steam are part of a hearing conservation programme described in this article. The tests and services are provided by the company with the cooperation of an academic institution which supplies the personnel for the tests and interpretations. The required periodic examinations are given by using automatic audiometers, and necessary follow-up tests (speech audiometry, tone decay, loudness balance) are given manually. Use of personal hearing protection is stressed as part of the test results. Problems are referred to medical centres. In addition, these procedures have turned up conditions, which were then treated, not associated with chronic noise exposure. The programme also enables students to prepare for industrial situations with several types of practical experience.

CIS 78-611 Near-miss at Browns Ferry - A brush with nuclear catastrophe.
Description of a fire in a nuclear power plant in the USA. To protect employees and the vicinity from radioactivity a vacuum was maintained in the reactor and reactor building, thus preventing radioactivity from escaping in case of leakage. Cables and wires from the reactor to the control room passed through holes in the concrete wall, sealed airtight. Workers checking for air leaks in the wall held lighted candles to the holes through which the cables passed. If the airtight seal had broken they would pack polyurethane foam into the hole. On finding a leak they packed it with foam, but not tightly enough. When they again held the candle to the hole the vacuum sucked the flame into the hole and the foam ignited, spreading to the cables. The damage to the cables resulted in false information being conveyed to the control room (e.g. indicating that some emergency systems had started up when in fact they had not). Systems continued to fail one by one and the reactor had to be shut down. The article analyses why the chain of events lead to a near-catastrophe (faulty equipment, lack of preparedness, inadequate maintenance, faulty methods, etc.).

Cancer as a factor of mortality in town gas workers
Krebs als Todesursache bei Beschäftigten der Gasindustrie [in German]
This research report is a retrospective analysis of causes of death among town gas workers and in some control industries (970 deaths between 1953 and 1972): population and methodology; relation between certain causes of death and smoking habits or type and duration of exposure; morphological aspects. A higher rate of mortality due to cancer of the respiratory or urinary tract was noted particularly in workers at the coke oven batteries and coal tar processing installations. The relation between the type of workpost and the occurrence of cancer was statistically very significant. 1 in 6 of the exposed workers died from cancer of the respiratory tract, compared to 1 in 16 among non-exposed persons. An average of 30-35 years elapsed between commencement of exposure and death due to cancer of the respiratory or urinary tract. Analysis of the results in the light of other research.

Determination of exposure to electric fields in extra high voltage substations.
Electrophysical effects related to extra high voltage (130-800kV) were surveyed to determine personnel exposure to electric fields. The electric field strengths and electric discharges to personnel were the important electrophysical factors. Instruments for measuring the field strength at grounded surfaces and at nonzero potentials were constructed. A dummy was used for measuring the distribution of capacitive currents to a person. The dummy can also be used to measure the effectiveness of special shielding clothes.

Cancer of the urinary tract in town gas workers
Harnwegskarzinome bei Beschäftigten der Gasindustrie [in German]
Statistical analysis of causes of death among personnel of a domestic gasworks of a large town showed a high rate of urinary tract carcinoma (in particular, 7 cases of hypernephroid carcinoma) in furnace battery and pipe distribution system workers. The author believes the causative agents to be substances contained in tar, in particular beta-naphthylamine. Average exposure was calculated to be 21 years, latency period 10.4 years and age at death, 65.9 years. Surgical treatment was successful where diagnosis was sufficiently early. The article stresses the importance of preventive measures, personal hygiene and periodic check-ups after cessation of occupational exposure.

Influence of noise on the peripheral vascular reaction and role of autonomic reflexes
Influence du bruit sur la réaction des vaisseaux sanguins périphériques et rôle des réflexes végétatifs. [in French]
Report submitted to the 8th International Congress on Noise (Basle, Switzerland, June 1974). The author describes experiments carried out in 10 healthy subjects aged 20-25 years, employed in a hydroelectric power station, who underwent laboratory noise tests (110-125dB with 131dB peaks), with predominant low-frequency sound (i.e. conditions resembling those encountered in their work). Plethysmographic and ECG recordings were taken and blood pressure was measured before and during exposure. The pulse became much less perceptible on exposure to intense noise; this was taken as evidence of considerable contraction of the peripheral blood vessels of the upper limbs. Data in the literature indicating changes in P and T waves of the ECG and those of the S-T segments, were not confirmed. Contrary to the findings of previous authors, this article reports minimal, or absence of, effects of noise on arterial blood pressure, but confirms previous reports that intense autonomic reflexes are more frequently found in socially maladjusted subjects.

Audiometric examinations of noise-exposed workers to determine progression of noise-induced hearing loss
Audiologische Untersuchungen an Lärmarbeitern zur Progredienz der Lärmschwerhörigkeit [in German]
Literature survey of the pathogenesis and clinical aspects of noise-induced hearing loss; description of audiometric examinations in 1,129 workers at a power station, with details of the noise exposure at the workplace (60-100dB(A)), and comparison with earlier results. A significant relation was found between hearing loss at 4,000Hz and the rating level at the workplace. Even after more than 20 years' exposure, tone audiometry still showed progression of hearing impairment. It is supposed that the "saturation phase" is longer for the sound levels recorded at the power station, which are as a whole lower than those noted in other studies. Speech audiometry yields no information on the evolution of deafness in time, but only on the ability to comprehend spoken messages.

Assessment and management of a plutonium contaminated wound case.
A plutonium contaminated wound is described together with its management. Initially 14.2 µCi of plutonium were present in the wound, this figure being reduced to about 1.8µCi after 2 excisions. During the period of assessment, DTPA was administered and the effect of this is discussed. Urinary excretion data were obtained and quantitative monitoring of the lymphatics of the arm and the liver were attempted. Various methods of assessment of body content are discussed which indicate the amount of retained plutonium to lie between 0.1 and 1.5 µCi. Chromosome culture from blood lymphocytes indicated probable preferential irradiation of these cells.

Chronic respiratory disease in a gas plant.
A report of a study carried out in a town-gas plant in Maharashtra to ascertain the health hazards associated with the manufacturing process. Workers are exposed to coal dust, benzene, naphthalene, pyridine and carbon monoxide. The gases present were below the maximum permissible levels, but coal dust levels exceeded the threshold limit value. 100 exposed workers and 60 controls were investigated, taking into account age, length of service and smoking habits. X-ray findings and clinical examination showed that the incidence of chronic bronchitis, emphysema and bronchiectasis was higher among exposed than among non-exposed workers.

Human costs of nuclear power
After having pointed out that public health efforts are often stimulated more by emotional attitudes among the public than by objective considerations, and that our knowledge of the biological effects of ionising radiations exceeds our knowledge of the effects of any other physical or chemical agent, the author assesses the human costs (accidental injuries to nuclear industry employees, and potential health hazards incurred by all persons exposed to radiation from the nuclear power industry) of producing and using nuclear fuel to generate electricity; these costs are said to be approximately 0.25 x 10-4 dollar per kWh. In terms of risk per person exposed, the mining and milling of uranium represents by far the costliest portion of the entire fuel cycle.
