Non-sensitising air pollution at workplaces and adult onset asthma.

OBJECTIVE: The aim of this study was to elucidate further whether occupational exposure to non-sensitising air pollution at workplaces increases the risk of adult onset asthma. METHODS: One hundred and twenty persons with asthma diagnosed by general practitioners, aged 20-65 years, were compared with 446 referents matched for age and gender and living in the same community as the cases. Information about occupation, exposure to specific allergens, smoking habits, dwellings and atopy was obtained from a postal questionnaire. The subjects' occupations were categorised as clean or polluted, based on the judgement of the referents on their respective occupations. RESULTS: Three years or more of work in air-polluted workplaces resulted in an odds ratio of 1.7 (95% confidence interval 1.0-2.7). Stratification of the material on smoking habits, gender or atopy did not alter the results, nor did exclusion of subjects exposed to specific allergens of statistical significance in this material, e.g. flour dust. Smoking per se did not bring any risk of asthma. Working in buildings affected by dampness and mould brought a fourfold significant risk. CONCLUSION: In this study occupational exposure to unspecific air pollution at workplaces was associated with an increased risk of adult-onset asthma.

Workplace disability in migraine: an Italian experience.

Workplace disability due to migraine has not been extensively researched in non-English speaking countries. We assessed the repercussions of headache, and particularly of migraine, on work in a sample of employees from an Italian company (Bulgari). Information was obtained through a self-answering questionnaire in "all headaches" sufferers, and through direct interview in migraine sufferers (diagnosis according to IHS criteria). Headache frequency, pain intensity and headache-related disability were higher in migraineurs than in "all headaches" sufferers. About a quarter of migraineurs missed at least one day in the three months prior to the interview due to headache, and around 10% lost two or more days over the same period. Moore than 50% of migraineurs reported 1-7 days per month at work with headache, with reduction in productivity level by 50% or more in 15% of respondents. Our data confirmed that headaches, and particularly migraine, cause a considerable reduction in workplace productivity. Workplace interventions to effectively manage migraine are needed.

Design of a difficult workplace fettling shop operations.

Fettling is a typical industrial operation involving processing with hand tools, and handling of materials. The ergonomics of fettling shops are examined in this article. Analysis of the workplace showed that the main causes of stress were the machines used and the direct design of the workplace. Changing the machine design would be a long-term project, so efforts were concentrated on the workplace. Aspects considered include noise, dust, transport, communication between operatives, and the design team. Reference is made to a particular installation in Sweden.

Ethical dilemmas in workplace health promotion.

In less than a decade, workplace health promotion programs designed to promote employee health and help reduce the high cost of health insurance premiums paid by business and industry have proliferated. Notwithstanding the latent benefits and cost savings that corporate management expects to gain from the investment in such programs, it is argued that workplace health promotion is not without potential misuse and that its goals and methods ought not to be above ethical scrutiny. Drawing on earlier work, we discuss how workplace health promotion may pose ethical problems related to social justice, protection of privacy, and social control. The attendant moral dilemmas for the professional whose responsibility it is to develop and implement such programs are also presented.

Workplace mental health consultation. A primer of organizational and occupational psychiatry.

Though there are only a few hundred psychiatrists who identify themselves as specialists in organizational and occupational issues, the need for psychiatric skills in the workplace has increased dramatically in recent years. Crucial issues include distressed employees, the effects of organizational structure and change, job stress, psychiatric disability, substance abuse, and violence in the workplace. It is important for general psychiatrists to become more conversant in work and workplace-related mental health issues. Use of an occupational history with all patients, and knowledge of organizational structures and function, are just two ways to become more aware of these matters. With business and government increasingly attentive to mental health benefits and systems, appropriate psychiatric focus on organizational and occupational concerns becomes ever more important.

Workplace wellness participation and the becoming of self.

This paper provides a sociological examination of workplace wellness participation as a process that occurs in two stages or levels. The existential model of self provides the theoretical orientation for this examination, and data are presented from an ethnographic study of a large workplace wellness program. The first stage or level of participation involves the establishment of a sense of competence. Competence refers to the perceived ability to 'fit in' with the program, to master the often subtle skills required for membership in the class. Once a minimal sense of competence is established, the employee may decide to join by viewing participation either as an extension of a commitment to wellness, or as a vehicle for experimenting with or establishing a new style of self, the identity of a 'well person' so highly valued in contemporary western culture. The dynamics of workplace wellness participation illustrate a more general cultural trend towards health-as-accomplishment.

Drug treatment staff attitudes toward AIDS and workplace transmission of HIV: a survey and follow-up--Spectrum House, Inc.

A growing number of cases of HIV infection and AIDS in the U.S. have been reported among intravenous drug users and their sexual partners. This increase in cases has begun to have a significant impact on substance abuse treatment programs; in addition to the complexities of HIV education and counseling, the staff of such programs must deal with their own fears regarding HIV infection, since many experientially trained staff are, themselves, former IV drug users. Other staff members may experience irrational anxiety about working HIV-infected clients, due to the fear of workplace exposure to the virus. In order to assess the extent and nature of such anxieties among its staff, Spectrum House, Inc., a comprehensive substance abuse treatment program, administered a Staff AIDS Survey in 1986 and again in 1987. Responses reflected a marked decrease in staff anxieties relating to workplace transmission of HIV during the 14-month period between surveys, seemingly related to both the implementation of AIDS education and an increase in contact with HIV positive clients. Those staff members whose contact with HIV positive clients remained infrequent between surveys, however, continued to show higher levels of fear about casual contact and workplace exposure to HIV. These results indicate that increased staff-client interaction may be an effective addition to other forms of staff AIDS education in substance abuse treatment programs.

Correlation of the exposure to a pollutant with a task-related action or workplace: the CAPTIV system.

Usually, measurement of pollution at the workplace is performed by air sampling on solid absorbents and filters. The information obtained is the mean value of worker exposure over the sampling period. The use of specific sensors for chemicals can give complementary information, namely continuous exposure information. The CAPTIV system permits one to centralize and store this information along with a video system which restores the images of the workplace. Also, the stored video sequences, correlated to specified exposures, can be found automatically. This gives a rich information resource. In particular it allows one to correlate the occupational activity with the exposure level. The analysis of collected information may lead to advice on good practice at the workplace or even to proposals for modification of existing equipment and processes. A huge quantity of information to be processed is obtained with this new approach. The best use of it can only be made with the help of a high capacity processing tool. That is the reason why CAPTIV has been equipped with a data processor support system. At the end of this paper, we present an example of using CAPTIV to study a stone-cutting work station.

Confronting workplace exposure to chemicals with LCA: examples of trichloroethylene and perchloroethylene in metal degreasing and dry cleaning.

Life-Cycle Assessment (LCA) aims to assess all environmental impacts "from cradle to grave". Nevertheless, existing methods for Life-Cycle Impact Assessment (LCIA) generally do not consider impacts from chemical exposure at the workplace. This is a severe drawback, because neglecting occupational health effects may result in product or process optimizations at the expense of workers' health. We adapt an existing LCIA method to consider occupational health effects from the use of perchloroethylene (PCE) and trichloroethylene (TCE) in dry cleaning and metal degreasing. The results show that, in applications such as metal degreasing and dry cleaning, long-term (steady-state) concentrations at the workplace are up to 6 orders of magnitude higher than ambient air levels. Legal threshold values may be exceeded, depending on machine technology, size, and surrounding working conditions. The impact from workplace exposure to the total human-toxicity potential of the complete life cycle of PCE and TCE (including use, production, and disposal) is accordingly high. We therefore conclude that occupational health effects need to be considered in LCA to prevent overlooking key environmental-health impacts in LCA.

Crossover of workplace aggression experiences in dual-earner couples.

This study investigates whether workplace aggression experienced by one or both members of a couple accounts for increases in the psychological distress of the victim's partner. Viewing the work-family interface and stress-strain processes as dyadic, and open to interindividual and interdomain contagion, analyses were conducted on matched data from a large-scale population health survey containing information on both working adults from 2,904 couples. Multilevel analysis of bidirectional crossover, while controlling for common stressors, supports the proposition of a crossover of stress resulting from workplace aggression. This finding highlights the complexities of work-family dynamics and of the deep penetration of workplace aggression into the lives of dual-earner partners.

Workplace stress in nursing: a literature review.

BACKGROUND: Stress perception is highly subjective, and so the complexity of nursing practice may result in variation between nurses in their identification of sources of stress, especially when the workplace and roles of nurses are changing, as is currently occurring in the United Kingdom health service. This could have implications for measures being introduced to address problems of stress in nursing. AIMS: To identify nurses' perceptions of workplace stress, consider the potential effectiveness of initiatives to reduce distress, and identify directions for future research. METHOD: A literature search from January 1985 to April 2003 was conducted using the key words nursing, stress, distress, stress management, job satisfaction, staff turnover and coping to identify research on sources of stress in adult and child care nursing. Recent (post-1997) United Kingdom Department of Health documents and literature about the views of practitioners was also consulted. FINDINGS: Workload, leadership/management style, professional conflict and emotional cost of caring have been the main sources of distress for nurses for many years, but there is disagreement as to the magnitude of their impact. Lack of reward and shiftworking may also now be displacing some of the other issues in order of ranking. Organizational interventions are targeted at most but not all of these sources, and their effectiveness is likely to be limited, at least in the short to medium term. Individuals must be supported better, but this is hindered by lack of understanding of how sources of stress vary between different practice areas, lack of predictive power of assessment tools, and a lack of understanding of how personal and workplace factors interact. CONCLUSIONS: Stress intervention measures should focus on stress prevention for individuals as well as tackling organizational issues. Achieving this will require further comparative studies, and new tools to evaluate the intensity of individual distress.

Psychometric assessment of patients with chronic upper extremity pain attributed to workplace exposure.

Upper extremity pain attributed to workplace exposure is a growing concern in medicine today. This study was undertaken to investigate the psychological findings in patients with chronic upper extremity pain attributed to workplace exposure. Sixty-three consecutive patients were evaluated. All patients underwent a history and physical examination by a hand surgeon and a psychological evaluation by a licensed psychologist, including a Minnesota Multiphasic Personality Inventory-2 (MMPI-2). Physical and psychological findings were then compared. Forty-one patients (65%) showed abnormalities on MMPI-2 examination (t score > 70 = 97% confidence). This result is far above what generally would be expected in medical patients. When physical findings were grouped with psychological findings, 5 distinct groups were identified: 1 patient had normal physical and psychological results, 6 patients had normal physical findings but abnormal psychological assessments, 21 patients had abnormal physical findings but normal psychological assessments, 28 patients had both abnormal physical and psychological findings, and 7 patients had abnormal physical results but invalid MMPI-2 evaluations due to purposeful attempts to deny psychological symptoms. Identification of these groups may have diagnostic, prognostic, and treatment value. In addition, identification of these groups may help clarify several aspects of the debate over the role of psychosocial factors in the development and maintenance of chronic upper extremity pain that patients attribute to workplace exposure.

Chemical dependency and drug testing in the workplace.

Urine testing for drug use in the workplace is now widespread, with the prevalence of positive drug tests in the work force being 0% to 15%. The prevalence of marijuana use is highest of the illicit drugs being tested. Highly prevalent drugs can be reliably tested. Although it is prudent to rid the workplace of drug use, there is little scientific study on the relationship of drug use and workplace outcomes, such as productivity and safety. Probable-cause testing and preemployment testing are the most common applications. Random testing has been less accepted owing to its higher costs, unresolved legal issues, and predictably poor test reliability. Legal issues have focused on the right to privacy, policy agreements, discrimination, and the lack of due process. The legal cornerstone of a good program is a policy that is planned and agreed on by both labor and management, which serves both as a contract and as a procedure in which expectations and consequences are known. Moreover, NIDA is certifying laboratories doing employee drug testing. Testing methods, when done correctly, are less prone to error than in the past, but screening tests can be defeated by adulterants. Although the incidence of false-positive results is low, such tests are less reliable when the prevalence of drug abuse is also low.

The smoke-free workplace.

As the significance of drug use and/or abuse in the workplace is explored, and the public is encouraged to embrace the War on Drugs, policymakers and treatment personnel must not concentrate only on illicit drugs but on licit drugs as well. This article explores the impact of cigarette smoking in the workplace and reviews alternatives for decreasing or eliminating exposure to involuntary smoke in the workplace.

Do EASE scenarios fit workplace reality? A validation study of the EASE model. Estimation and Assessment of Substance Exposure.

Within the framework of European risk assessment of new and existing substances, the EASE model (Estimation and Assessment of Substance Exposure) is often applied to assess inhalative exposure at workplaces. To contribute to the validation of this model, single EASE scenarios were compared with independent measurement data on inhalative exposure to vapors and dusts. For this purpose, workplace measurements obtained in the areas of production, textile printing and coating, screen printing and offset printing, the rubber industry, and the plastics processing industry as well as flame spraying were used. A good correspondence between model estimates and measurement data was found in the case of exposure to vapors for the production of chemical substances in closed systems (EASE scenario: closed system without breaching) and for procedural control works at mainly automated printing workplaces (EASE scenarios: non dispersive use, segregation, low/medium volatility). For the handling of powdery substances measurement results obtained during weighing and filling works, in part semiautomatic, were compared with the EASE estimates for the scenario: dry manipulation, with/without local exhaust ventilation. Good correspondence was estimated if approx. 1 t to 200 t powdery substances were handled per shift. For the EASE scenarios "direct handling with natural ventilation/with local exhaust ventilation," high discrepancies exist between model prediction and measurement results obtained during manual screen printing or the preparation of printing inks.

Workplace and environmental air contaminant concentrations measured by open path Fourier transform infrared spectroscopy: a statistical process control technique to detect changes from normal operating conditions.

Open path Fourier transform infrared (OP-FTIR) spectroscopy is a new air monitoring technique that can be used to measure concentrations of air contaminants in real or near-real time. OP-FTIR spectroscopy has been used to monitor workplace gas and vapor exposures, emissions from hazardous waste sites, and to track emissions along fence lines. This paper discusses a statistical process control technique that can be used with air monitoring data collected with an OP-FTIR spectrometer to detect departures from normal operating conditions in the workplace or along a fence line. Time series data, produced by plotting consecutive air sample concentrations in time, were analyzed. Autocorrelation in the time series data was removed by fitting dynamic models. Control charts were used with the residuals of the model fit data to determine if departures from defined normal operating conditions could be rapidly detected. Shewhart and exponentially weighted moving average (EWMA) control charts were evaluated for use with data collected under different room air flow and mixing conditions. Under rapidly changing conditions the Shewhart control chart was able to detect a leak in a simulated process area. The EWMA control chart was found to be more sensitive to drifts and slowly changing concentrations in air monitoring data. The time series and statistical process control techniques were also applied to data obtained during a field study at a chemical plant. A production area of an acrylonitrile, 1,3-butadiene, and styrene (ABS) polymer process was monitored in near-real time. Decision logics based on the time series and statistical process control technique introduced suggest several applications in workplace and environmental monitoring. These applications might include signaling of an alarm or warning, increasing levels of worker respiratory protection, or evacuation of a community, when gas and vapor concentrations are determined to be out-of-control.

Workplace measurement of respirator effects using respiratory inductive plethysmography.

A useful system to study the cardiopulmonary effects of respirators in the workplace would be reliable, portable, and lightweight and would not encumber the nose or mouth or require modification to the respirator. Twenty men using such a system (which measured ventilatory parameters by respiratory inductive plethysmography [RIP]) were studied. The subjects all performed their usual jobs which involved some work with and some without a respirator. Twelve subjects used airline respirators and eight used air-purifying respirators. The RIP equipment measurements included respiratory frequency, tidal volume (VT), minute ventilation (V), and heart rate (HR). The RIP data from 20 other subjects was lost because of equipment malfunction, primarily lead separation in those whose jobs involved climbing around large workpieces. In general, the workers' cardiopulmonary parameters increased during respirator wear, probably because of a combination of factors, including the increased exercise of most respirator-requiring tasks and the weight and heat stress associated with the respirator and protective clothing. When the ventilatory parameters with and without a respirator were compared at the same heart rates, no significant differences were noted in VT for the entire group. Respiratory frequency, however, and V increased with respirator wear. The effects of respirators alone were found to be commonly confounded in the workplace by changes in protective clothing, exercise requirements, and ambient heat stress. Further improvements in the portable RIP system are needed before it can be accepted as a reliable ventilatory measurement device in the workplace.

AIDS series--paper III-B. Prevention of HIV transmission in the workplace: categorization of jobs and tasks by risk of HIV infection.

The risk to workers of exposure to HIV or other blood-borne infectious diseases on the job is dependent upon the likelihood of exposure to blood, body fluids, or tissues while performing the tasks required by the job. Three categories of workplace-associated risk of HIV exposure have been defined. These categories can be summarized as follows. Category I--Regular or Frequent Exposure Potential. Applies primarily to health-care workers, including emergency medical workers. These workers are at greatest risk of occupationally acquired HIV disease. Category II--Intermittent Exposure Potential. Applies to persons such as police officers, fire fighters, and correctional facility personnel. Category III--Rare or No Exposure Potential. Applies to most jobs in the service and manufacturing industries, including office personnel. These workers are at no greater risk than the general public for exposure to HIV. As there is definite risk to Category I and II workers of becoming infected with HIV while performing duties required by their jobs (their risk of acquiring HBV is much greater), it is important for employers in these workplaces to establish procedures to prevent the exposures that may lead to infections. The first step in this process is to analyze carefully tasks performed within the workplace to identify Category I and II tasks, as described in the DOL/DHHS Joint Advisory Notice. Once this has been done, the DOL/DHHS document and pertinent CDC recommendations should be used to develop specific procedures for those workers at risk.
