Does the use of biofuels affect the respiratory health among male Danish energy plant workers?
Respiratory symptoms in 138 woodchip workers, 94 straw workers and 107 control workers from 85 heating- or combined heating and power plants were collected by questionnaire. Spirometry, metacholine provocation tests and skin prick tests were performed on 310 workers. The work area concentrations of total dusts, airborne endotoxins, cultivable Aspergillus fumigatus and cultivable fungi were measured at each plant. Personal exposure was calculated from the time spent on different tasks and average work area exposures. Exposure levels are discussed. Exposure levels were increased in biofuel plants compared with conventional plants. The prevalences of respiratory symptoms among conventional plant and biofuel plant workers were comparable, except for asthma symptoms among non-smokers, which were higher among straw workers compared with controls. A trend for increasing respiratory symptoms with increasing endotoxin exposure was seen with odds ratios (ORs) between 3.1 (work-related nose symptoms) and 8.1 (asthma symptoms) for the most exposed group. Associations between fungal exposure and respiratory symptoms were less clear but suggested cultivable fungi to be associated with asthma symptoms and work-related respiratory symptoms. No associations were seen between lung function and the level of endotoxin or fungal exposure. It is concluded that working with biofuel at an energy plant does not generally enhance the prevalence of respiratory symptoms. However, the exposure level to microorganisms has an impact on the occurrence of respiratory symptoms among biofuel workers.

A cohort mortality study of chemical laboratory workers at Department of Energy nuclear plants
This study evaluated the mortality causes of 6157 chemical laboratory workers employed at United States Department of Energy facilities. All cause, all cancer and cause-specific standardized mortality ratios were calculated. Cox regression analyses were conducted to further evaluate the relation between chemical exposure and mortality risk due to selected cancers. The mortality due to all causes combined and all cancers combined were below expectation for the cohort. There were no statistically significant elevations reported among men for any specific cancer or non-cancer outcome. Neither were there any statistically significant elevations among women for any specific non-cancer and most specific cancers; however, multiple myeloma deaths were significantly elevated (SMR=3.56). Statistically significant elevations of leukaemia were observed among workers employed 20 years or more, together with a statistically-significant trend of elevated lung cancer mortality with increasing employment duration. Other findings are discussed.

Model-based analysis of an arc protection and an emergency cooling system - MODSAFE 2007 work report
This report describes model-checking techniques applied to an arc protection system and to an emergency nuclear reactor cooling system. Model checking tools consist typically of a modelling language for modelling the system to be verified, a specification language (or temporal logic) for expressing the properties to be verified and a set of analysis tools to check that the system satisfies the given properties. Using a state-of-the-art open source model checking system, it was possible to adequately model both systems, to formulate required safety properties in the specification language and to perform a full verification of the properties. This work shows that current model checking techniques are applicable in the analysis of safety instrumentation and control systems in nuclear power plants.

Human resource management in organizational change and the issue of mobbing: An Italian experience
La gestione delle risorse umane nelle organizzazioni che cambiano e la problematica del mobbing: un'esperienza italiana [in Italian]
Staff redundancies that often result from mergers and organizational changes in the business world are difficult to implement in public sector companies, where such changes often lead to mobbing. The objective of this survey of the power sector, which in recent years has been affected by considerable organizational changes, was to determine the frequency and risk factors of mobbing. Data were collected by means of questionnaires. Findings show a working environment that tends to isolate and alienate a significant number of workers, one out of three, who explicitly claimed that they felt victims of psychological violence and also felt useless and little appreciated in performing a meaningless job. On the whole, women and older workers tend to be the most exposed to psychological abuse. The older were not old enough to benefit from early retirement schemes and who, like women, were unable to return to the labour market with confidence after years of harassment and humiliation.

External radiation exposure and mortality in a cohort of French nuclear workers
The objective of this study was to analyse the effect of external radiation exposure on the mortality of French nuclear workers. A cohort of 29,204 workers employed between 1950 and 1994 at the French Atomic Energy Commission (CEA) or at the General Company of Nuclear Fuel (Areva) was followed up for an average of 17.8 years. Standardized mortality ratios were computed with reference to French mortality rates. Dose-effect relationships were analysed through trend tests and Poisson regression, with linear and log-linear models. A healthy worker effect was observed, the number of deaths in the cohort being 59% of the number expected from national mortality statistics. Among the 21 main cancer sites studied, a statistically significant excess was observed only for skin melanoma, while an excess of borderline statistical significance was observed for multiple myeloma. A dose-effect relationship was observed for leukaemia after exclusion of chronic lymphoid leukaemia. Other findings are discussed.

Occupational exposure to power frequency magnetic fields and risk of non-Hodgkin lymphoma
The objective of this study was to investigate the risk of non-Hodgkin lymphoma (NHL) due to occupational exposure to magnetic fields of 50-60Hz. The study population consisted of 694 cases of NHL, first diagnosed between 1 January 2000 and 31 August 2001, and 694 controls from two regions in Australia, matched by age, sex and region of residence. A detailed occupational history was given by each subject. Occupational exposure to power-frequency magnetic fields was estimated using a specially-developed job-exposure matrix. The odds ratio (OR) for workers in the upper quartile of exposure was 1.48 compared to the referent group. When the exposure was lagged by five years the OR was 1.59. Adjusting for other occupational exposures did not significantly alter the results. These findings provide weak support for the hypothesis that occupational exposure to 50-60Hz magnetic fields increases the risk of NHL.

Airborne crystalline silica concentrations at coal-fired power plants associated with coal fly ash
This study presents the results of the measurements of airborne concentrations of crystalline silica dust in the breathing zone of workers exposed to fly ash. Six plants were studied; two were fired with lignite, and the other four used bituminous and sub-bituminous coals. A total of 108 personal breathing zone respirable dust air samples were collected. The results from bituminous and sub-bituminous fired plants revealed that the highest airborne fly ash concentrations are encountered during maintenance activities: 0.008mg/m3 to 96mg/m3 (mean of 1.8mg/m3). This group exceeded the threshold limit values (TLV) in 60% of the air samples. During normal production activities, airborne concentrations of crystalline silica ranged from non-detectable to 0.18mg/m3 (mean value of 0.048mg/m3). Other findings concerning the particle sizes and the crystalline forms of silica are discussed.

Case study for underground workers at an electric utility: How a research institution, university, and industry collaboration improved occupational health through ergonomics
Two ergonomic intervention teams were created at a medium-sized electric power utility to identify tasks with risk factors for musculoskeletal disorders and propose ergonomic interventions for these tasks. Both teams focused on tasks performed by underground workers: one team focused on manhole-vault tasks and the other team focused on direct-buried cable job tasks. Several of the ergonomic interventions were tested at a university ergonomics laboratory. The results of one of the laboratory experiments indicated that a 2nd class lever tool reduced muscle forces required to remove and replace a manhole cover, compared with a T-handle attached to a hook and chain. The results of another laboratory experiment demonstrated that a battery-powered cutter reduced muscle forces to cut cable as compared to a manual cutting tool.

Electricians' perception of work-related risks in cold climate when working in high places
Work on telecommunications and electricity transmission masts can be especially demanding in cold winter climates. This study sought to evaluate workers' perception of work-related risks in the above conditions with special reference to the use of hand tools. A questionnaire and interviews about workers' risk perception were used. A total of 170 questionnaires were sent, of which 118 were returned. Six respondents were also interviewed. It is concluded that in both the telecommunications and electricity transmission sectors, tools, ice and equipment falling from masts were the greatest perceived risks, and preventing such occurrences is the key to any improvement of safety.

Prevalence and characterization of hearing loss among workers exposed to industrial noise in the electricity turbogeneration plant of a petrochemical complex
Prevalencia y caracterización de la pérdida auditiva en trabajadores expuestos a ruido industrial de una planta eléctrica turbogenerada en un complejo petroquímico [in Spanish]
This study investigated the impact of occupational exposure to noise and its relationship with other factors that can induce hearing loss among workers in the electricity generating plant of a petrochemical complex in Venezuela. A cross-sectional study was conducted that involved medical examinations and audiometric tests on 75 workers. The equivalent noise levels (Leq) were quantified at various workplaces. It was found that most of the workers were exposed to high noise levels (>85dBA) and for more than the recommended time. All workers used hearing protectors appropriately. Although the hearing loss prevalence in workers was 16.0%, it was not possible to prove that it was noise induced. The hearing threshold registered in the audiometric tests was diminished, but remained within normal threshold values. Twelve cases of grade I conductive hearing loss were diagnosed, with no sensorial or mixed hearing losses. No relationship was found between the equivalent noise level and hearing loss. Recommendations for workers' protection are made, including the implementation of a hearing protection programme.

Neurovegetative disturbances in workers exposed to 50 Hz electromagnetic fields
This study was undertaken to assess autonomic function in workers occupationally exposed to 50Hz electromagnetic fields (EMFs) by analyzing the heart rate variability. The study group comprised 63 workers of switchyard substations, aged 22-67 years and a control group of 42 workers with no EMF exposure. To assess the neurovegetative regulation of the cardiac function, heart rate variability (HRV) was analysed based on 512 normal heart beats recorded at rest. The relative risk of decreased HRV, calculated with use of a logistic regression model, was significantly higher in the exposed group than in controls (odds ratio 2.8). It is concluded that occupational exposure to 50Hz EMF could influence the neurovegetative regulation of the cardiovascular system.

Electromagnetic fields and health effects - Epidemiologic studies of cancer, diseases of the central nervous system and arrhythmia-related heart disease
This epidemiological investigation comprised separate studies of the risk of cancer, cause-specific mortality rates, risks for neurodegenerative diseases and the risk of cardiac arrhythmia among employees exposed to extremely-low frequency (50Hz) electromagnetic fields in the Danish utility industry. The risk for cancers considered to be possibly associated with the radiofrequency fields emitted by mobile telephones was also examined in a large cohort of mobile telephone users. On the basis of these studies and of the scientific literature, it is concluded that occupational exposure to 50Hz electromagnetic fields is not associated with the overall risk of cancer, neurodegenerative diseases or cardiovascular diseases, although there is some indication that these fields (or some other unknown factor related to alternating current electricity) may be associated with the risk of amyotrophic lateral sclerosis.

The relationship between systematic OHS management and sick leave
The aim of this study was to describe the level of occupational health and safety (OHS) management system (OHSMS) implementation in the Norwegian energy sector, and to investigate whether it had any bearing on workers' health. A sample of 13 electricity companies was surveyed. Data were collected through two postal questionnaire surveys, followed by selective interviews of key personnel. Most companies had established OHSMS and had satisfactory mapping systems for sick leave and risks. However in many enterprises, there were gaps with respect to the evaluation of psychosocial factors, the systematic follow-up of OHS issues at meetings, and interventions to improve conditions. The study showed that there was a relationship between activities at the organizational level and sick leave measured at both individual and organizational levels.

Cancer mortality among French atomic energy commission workers
All causes and cancer mortality of 58,320 workers employed at French Atomic Energy Commission (Commissariat à l'Energie Atomique) between 1946 and 1994 were compared with that of the general population in a retrospective cohort study. Standardized mortality ratios (SMRs) were calculated. Between 1968 and 1994, 4,809 deaths occurred. A healthy worker effect is observed for both men (SMR=0.57) and women (SMR=0.72). Nine sites of cancer death were found to be in statistically significant deficit among men, none among women. An excess of pleural cancers (SMR=1.79) and malignant melanoma (SMR=1.50) are observed among men, while a marginally-significant excess of breast cancer is observed among women (SMR =1.14).

Psychosocial factors at work and self reported health: Comparative results of cross sectional and prospective analyses of the French GAZEL cohort
To explore the relationship between psychosocial factors at work and self-reported health, cross-sectional and prospective analyses were carried out on data from a large occupational cohort of men and women employed at a large French gas and electricity utility. Psychosocial factors at work were evaluated using the Karasek questionnaire, designed to measure psychological demands, decision latitude, social support and physical demands. Self-reported health was used as health outcome. Variables analysed included chronic diseases, and socio-demographic, occupational and behavioural factors. Cross-sectional analysis revealed significant associations between psychological demands, decision latitude, social support and physical demands, as well as self-reported health for both men and women. Prospective analysis showed that high psychological demands for both sexes, low decision authority for men, and low social support and high physical demands for women, were related to poor self-reported health. These results were independent of potential confounding variables.

Challenges and opportunities facing public utilities
Les défis à relever et les tendances à saisir par les services publics de distribution [in French]
Los retos y oportunidades que se plantean a los servicios públicos [in Spanish]
This report was presented for discussion at a tripartite meeting on challenges and opportunities facing public utilities. It reviews some of the continuing trends concerning the sector's employment and social issues and considers the role of multinational enterprises in the sector and the impact of mergers and acquisitions. Renewable energy and sustainable development are also key challenges that open up opportunities for governments, employers and workers. The case of water utilities is also specifically examined, as this sector embarks on the path that electricity and gas have already started. A chapter is devoted to occupational safety and health in this sector. Finally, the report reflects on the importance of social dialogue in a rapidly globalizing industry.

Asbestos-related diseases compensated by Electricité-de-France et Gaz-de-France: A retrospective 23-year study
Les maladies professionnelles liés à l'amiante indemnisées à Electricité-de-France et Gaz-de-France: résultats d'une enquête rétrospective sur 23 ans [in French]
The purpose of this study was to characterize the trends in compensated asbestos-related diseases among employees of the French national electrical and gas utility (Electricité-de-France and Gaz-de-France, EDF-GDF), with respect to their nature and frequency, the age and sex of the victims, clinical peculiarities, exposure locations and duration, latency and lag times, levels and delays of compensation. A retrospective study was carried out involving the 704 cases compensated between 1977 and 2000 based on information obtained from the medical archives of the health insurance fund covering these industries. It was found that non-malignant pleural pathologies were the most frequent (68%), followed by pulmonary fibrosis (11.4%) and mesothelioma (11.2%). Lung cancer represented 9.3% of these diseases. There was a dramatic increase in overall frequency from 1996. Most persons who declare these occupational diseases are retired; their mean age is 61.6 years old and is significantly rising. The population is essentially male. Average exposure and latency times are 23.5 and 36.8 years, respectively. The mean compensation delay is 29.5 months but getting progressively shorter.

Association of low job control with a decrease in memory (CD4+CD45RO+) T lymphocytes in Japanese middle-aged male workers in an electric power plant
To clarify the relationship between perceived job stress and lymphocyte sub-populations, a cross-sectional study was conducted in 231 male electric power plant workers (aged 40 to 60, mean 46 years). Job stress was assessed by means of the Japanese version of the Job Content Questionnaire. Blood samples were taken from all the workers, and numbers of CD4+T lymphocyte sub-populations, total CD4+T, T(CD3+1) lymphocytes, CD16CD56+ natural killer cells, total lymphocytes and white blood cells were determined. After controlling for age, number of cigarettes smoked per day, alcohol drinking, regular exercise, job demands, and social support at work, numbers of memory (CD4+CD45RO+)T, total CD4+T, and total T(CD3+) lymphocytes were positively correlated with job control. Neither job demands nor social support at work showed significant correlation with lymphocyte subpopulations.

Assessment of electrical accidents in power industry
This article is an assessment of the electrocutions that occurred between 1992 and 1996 to workers in the electrical utility sector in Greece. Data concerning the occupational characteristics of the injured person, the time (day of the week, time of the day) at which the accident occurred and the consequences are presented and discussed. A method for calculating the accident frequency rate per 1,000 workers, with emphasis on fatal accidents, is proposed. Also, an information system for accidents is proposed that would be capable of calculating the frequency and severity rates per workplace, per group, and per occupational category of the workers. It would also classify workers according to the occupational risks they face.

Effects of stress on psychophysiological parameters of electricity distribution network controllers in Ukraine
Electricity distribution controllers are responsible for balancing supply and demand for electricity under planned and unforeseen equipment shut-downs and network disruptions. To study the effects of stress on the cognitive performance and the cardiovascular system of controllers, 16 controllers working 12-hour shifts were studied. A five-point scale was used to estimate the perceived level of stress. The most pronounced changes in heart rate, circulatory minute volume and Kerdo's vegetative index were found during the first day shift and less pronounced changes appeared during the first night shift. Effects of stress on the studied parameters were not found during the second consecutive day or night shift. Increased stress causes the activation of psychophysiological functions that are indispensable for ensuring work efficiency under increased production demands. However, the necessary activation could not be maintained during the second consecutive 12-hour shifts. There was no observed effect of stress on short-term memory.

Assessment of exposure to ceramic fibres during insulation operations in a thermoelectric power plant
Valutazione dell'esposizione a fibre ceramiche durante la coibentazione degli impianti di una centrale termoelettrica in costruzione [in Italian]
Personal and workplace sampling was performed during maintenance work on electrical equipment in a large thermal generating plant involving the handling of insulating blankets. In personal samples, levels of exposure to ceramic fibres of up to 1000 fibres/L were measured. Average concentration levels from area samples were consistently lower. Because of the carcinogenic potential of ceramic fibres, it is recommended that adequate working practices and control measures be introduced, including the adoption of pre-coated and pre-shaped fibrous materials whenever possible, isolation of the working area, use of local air extraction ventilation, use of garments for personal protection and respirators, use of wetting or binding liquids prior to removal and fast elimination of debris from the working area.

Control of chemical risks during the treatment of soil contaminated with chlorophenol, creosote and copper-chrome-arsenic-wood preservatives
Exposure to chemicals was studied during the remediation of four polluted sites: a sawmill contaminated with chlorophenols, polychlorinated dioxins and furans (PCDD/F), a wood impregnating plant contaminated with polycyclic aromatic hydrocarbons (PAH), an old gas works area contaminated with PAH, and a wood impregnation plant contaminated with copper-chromium-arsenic (CCA) preservative. Air monitoring showed that the exposure levels were generally well below the current occupational exposure limits. However, the recommended daily intake value for PCDD/F was exceeded. Chlorophenol exposure was generally low. Exposure to volatile PAH was 0.038-0.884mg/m3 and that to particulate PAH was 0.004-0.183mg/m3. The biomonitoring results (urinary 1-pyrenol) suggested that some exposure occurs, probably through the contamination of hands or skin absorption. Exposure limits were not exceeded at the site contaminated with CCA. More attention should be given to skin protection.
