Objective: The ongoing presence of asbestos in products used across workplaces in Canada reinforces the importance of occupational exposure surveillance. This study evaluates the usefulness of the Ontario Asbestos Workers Registry.

Methods: The study includes 30,829 workers aged 15 to 80 years. Researchers reported on the data quality and analyzed the proportions of workers exposed by industry, and standardized rates by geographic areas and over time.

Results: The incidence of exposure started to decrease around 1990; but about 2000 workers were still exposed annually until 2006. Results showed large geographical disparities. Unexpectedly, workers from industries other than construction reported exposure.

Conclusions: The Ontario Asbestos Workers Registry is a useful but challenging source of information for the surveillance of asbestos exposure in Ontario. The registry could benefit from well-defined surveillance objectives, a clear exposure definition, systematic enforcement, regular data analyses, and results dissemination.

Objective: To investigate whether suicide risk among agricultural workers is higher in regions with heavier pesticide use and/or presence of tobacco farming.

Methods: Suicide mortality data were gathered from residents of the Brazilian state of Alagoas. Agricultural census data were used to arrange and classify Alagoas cities into distribution groups on the basis of variables concerning pesticide use and/or tobacco farming. Mortality odds ratio calculations were then used to compare suicide risk among agricultural and nonagricultural workers in different groups.

Results: Suicide risk was higher among agricultural workers than among nonagricultural workers, elevated in regions that used more pesticides, and greatest in regions that produced more tobacco.

Conclusions: This is one of the first studies of its kind to suggest that combined effects of pesticide and tobacco exposure may be linked to higher suicide risk among agricultural workers.

Objective: To respond to the question, “Do workplace health promotion programs work?”

Methods: A compilation of the evidence on workplace programs' effectiveness coupled with recommendations for critical review of outcome studies. Also, reviewed are recent studies questioning the value of workplace programs.

Results: Evidence accumulated over the past three decades shows that well-designed and well-executed programs that are founded on evidence-based principles can achieve positive health and financial outcomes.

Conclusions: Employers seeking a program that “works” are urged to consider their goals and whether they have an organizational culture that can facilitate success. Employers who choose to adopt a health promotion program should use best and promising practices to maximize the likelihood of achieving positive results.

Ethical principles in our Interactions

Ethics in occupational health is essentially a field of interactions between many partners. As our own experiences confirm, good occupational health is inclusive, not exclusive. Through the interactions with our partners, we learn and assess the broad scope as well as the values and ethics of our professional conduct. The elaboration and the implementation of professional conduct standards involve not only occupational health professionals but also those who will benefit from or may feel threatened by their practice. Such interactions relate to a range of risks in diverse employment and working conditions, and therefore require careful approaches in performing the duties of occupational health professionals for protecting and promoting workers’ health, respecting human dignity and impartiality and protecting confidential information.

Therefore in the revised Code, a renewed emphasis is placed on the integrity and professional independence of occupational health professionals who must not allow their judgment and statements to be influenced by any conflict of interest, in acting within the interactive relationships of their practice. A new provision of the Code thus refers to the need to keep their integrity by ensuring that the harm does not accrue with respect to workers’ health and public health as a result of conflicts.

A new provision concerning organizational ethics mentions that institutions and organizations employing occupational health professionals should adopt a programme of organizational ethics that is aligned with the ethical principles of the Code. Further new provisions also mention that contracts of employment should describe advisory roles and state professional independence of occupational health professionals.

In applying the Code, it should be stressed that ethics is considered as a subject that has no clear end boundaries and therefore requires well-thought interactions, multidisciplinary cooperation, consultations and participation. It is important to consider a code of ethics as a milestone of a dynamic process involving the occupational health community as a whole, by promoting a positive social climate and constructive interactions with the participating actors.

Background Pneumoconiosis is a form of diffuse interstitial lung disease, often resulting from occupational exposures. As dental prosthetic technicians (DPTs) build prostheses, they are exposed to many chemical materials that increase their risk of developing pneumoconiosis.

Aims To document pulmonary function and prevalence of pneumoconiosis in DPTs.

Methods A cross-sectional study of DPTs working in prosthetic laboratories who underwent pulmonary function test and high-resolution chest computed tomography (HRCT) scanning.

Results There were 76 participants and pneumoconiosis was diagnosed in 46%. The most commonly seen radiological finding was round opacities, present in 38%. Agreement among HRCT readers was moderate to good. As defined by HRCT, emphysema was diagnosed more often in those with a longer occupational history or a history of smoking, and low carbon monoxide diffusion capacity (DLCO), but not in those with pneumoconiosis. Forced expiratory rate and DLCO were significantly lower in those who had worked 16 years or more (all P < 0.05). DLCO values were significantly lower in technicians with emphysema and in current smokers (all P < 0.01). Round opacities were also present in a substantial proportion of DPTs who had 15 years or less exposure. Because HRCT is able to detect radiological changes of occupational lung disease very early, the prevalence of pneumoconiosis in our participants was quite high.

Conclusions Pneumoconiosis identified by HRCT was present in almost half of DPTs surveyed. Appropriate education and workplace protection should be given to DPTs in order to prevent exposure to hazardous materials in dental prosthetics laboratories.

Key words: Dental technicians, pneumoconiosis, occupational disease, respiratory disease.

Objectives To describe the prevalence of lung function abnormality and coal workers’ pneumoconiosis (CWP) by mine size among underground coal miners in Kentucky, Virginia and West Virginia.

Methods During 2005–2012, 4491 miners completed spirometry and chest radiography as part of a health surveillance programme. Spirometry was interpreted according to American Thoracic Society and European Respiratory Society guidelines, and radiography per International Labour Office standards. Prevalence ratios (PR) were calculated for abnormal spirometry (obstructive, restrictive or mixed pattern using lower limits of normal derived from National Health and Nutrition Examination Survey (NHANES) III) and CWP among workers from small mines (=50 miners) compared with those from large mines.

Results Among 3771 eligible miners, those from small mines were more likely to have abnormal spirometry (18.5% vs 13.8%, p<0.01), CWP (10.8% vs 5.2%, p<0.01) and progressive massive fibrosis (2.4% vs 1.1%, p<0.01). In regression analysis, working in a small mine was associated with 37% higher prevalence of abnormal spirometry (PR 1.37, 95% CI 1.16 to 1.61) and 2.1 times higher prevalence of CWP (95% CI 1.68 to 2.70).

Conclusions More than one in four of these miners had evidence of CWP, abnormal lung function or both. Although 96% of miners in the study have worked exclusively under dust regulations implemented following the 1969 Federal Coal Mine Safety and Health Act, we observed high rates of respiratory disease including severe cases. The current approach to dust control and provision of safe work conditions for central Appalachian underground coal miners is not adequate to protect them from adverse respiratory health effects.

Work-related health inequalities are determined to some extent by an unequal exposure to chemical and biological risk factors of disease. Although their potential economic burden in the European Union (EU-25) might be substantial, comprehensive reviews focusing on the distribution of these risks across occupational groups are limited. Thus, the main objective of this review is to provide a synopsis of the exposure to chemical and biological hazards across occupational groups. In addition, main industrial applications of hazardous substances are identified and some epidemiological evidence is discussed regarding societal costs and incidence rates of work-related diseases.

Available lists of carcinogens, sensitisers, mutagens, reprotoxic substances and biological hazards were consulted. For each work-related hazard the main industrial application was identified in order to assess which ISCO occupational groups may be associated with direct exposure. Where available, information on annual tonnage production, risk assessment of the substances and pathogens, and other relevant data were collected and reported.

Altogether 308 chemical and biological hazards were identified which may account to at least 693 direct exposures. These hazards concentrate on the following major occupational groups: technicians (ISCO 3), operators (ISCO 8), agricultural workers (ISCO 6) and workers in elementary occupations (ISCO 9). Common industrial applications associated with increased exposure rates relate among others to: (1) production or application of pigments, resins, cutting fluids, adhesives, pesticides and cleaning products, (2) production of rubber, plastics, textiles, pharmaceuticals and cosmetics, and (3) in agriculture, metallurgy and food processing industry, Societal costs of the unequal distribution of chemical and biological hazards across occupations depend on the corresponding work-related diseases and may range from 2900 EUR to 126000 EUR per case/year.

Risk of exposure to chemical and biological risks and work-related disease incidence are highly concentrated on four occupational groups. The unequal burden of exposure across occupations is an important contributing factor leading to health inequalities in society. The bulk of societal costs, however, are actually being borne by the workers themselves. There is an urgent need of taking into account the health impact of production processes and services on workers’ health.

Keywords: Work-related diseases; Occupational diseases; Chemical and biological occupational hazards; Social determinants of health.

This study aimed to assess the psychological work characteristics and psychological workload of train drivers and to define the psychological and cognitive requirements of their work. A systematic literature search was performed, and expert interviews were conducted. The following work demands were specific to train drivers: high emotional and mental demands, small amount of autonomy and skill discretion. No evidence of a high emotional workload, a high mental workload or short-term stress reactivity was found. In general, the drivers' fatigue complaints and recovery needs after work were comparable to that of other workers. However, severe sleepiness and high need for recovery did affect a substantial proportion of train drivers. The ability to stay aware, to anticipate, to remain attentive and to cope with fatigue are psychological and cognitive skills that are required to adequately and safely perform the train drivers' job. Including these requirements in periodic assessments of train drivers is recommended.

Practitioner Summary:

A systematic literature search was performed, aimed at assessing the psychological work characteristics and psychological workload of train drivers. Based on this information and interviews with experts, a list of psychological and cognitive requirements that needed to perform the train drivers' job adequately and safely was proposed.

Objectives: We aimed to study the association between low back pain (LBP) and exposure to low temperature, wet clothes, heavy lifting and jobs that involve whole body vibration (WBV) in a population of miners. Methods: Health and personal data were collected in a population study by a questionnaire. A total of 3530 workers from four mines participated in the study. Results: 51% of the workers reported LBP within the last 12 months. The adjusted odds ratio for LBP was above unity for working with wet clothes (1.82), working in cold conditions (1.52), lifting heavy (1.54), having worked as a driver previously (1.79) and driving Toro400 (2.61) or train (1.69). Conclusion: Wet clothing, cold working conditions, heavy lifting, previous work as a driver and driving certain vehicles were associated with LBP, but vehicles with WBV levels above action value were not. For better prevention of LBP, improved cabin conditions and clothing should be emphasised.

Practitioner Summary:

To address risk factors for low back pain (LBP) in miners, a population study measured exposures and LBP. Cold work conditions, wet clothes and awkward postures appeared to be more strongly associated with LBP than exposure to whole body vibration from driving heavy vehicles. Prevention strategies must focus more on clothing and ergonomics.

For the past decade, researchers' attention to abusive supervision (Tepper, 2000, Acad. Manage. J., 43, 178) has grown consistently. However, little is still known as to why certain individuals are picked by supervisors as targets for abuse. Our study tests a model of antecedents of abusive supervision, building on the profile of submissive employees (Aquino & Lamertz, 2004, J. Appl. Psychol., 89, 1023) and examining the potential role played by the work context. With a sample of 193 employee–supervisor dyads from downsized and non-downsized organizations, we found that as core self-evaluations and coworker support decreased, abusive supervision increased, particularly in downsized organizations, and this effect carried over to both in-role and extra-role performance. Using a displaced aggression framework (Hoobler & Brass, 2006, J. Appl. Psychol., 91, 1125), our study contributes to the discussion of the antecedents of abusive supervision by emphasizing the roles played (1) by the victim and (2) by the context in which these events take place.

Practitioner points

  • Supervisors aim their abusive behaviours at subordinates that appear particularly vulnerable and submissive.
  • Strategies to prevent/reduce supervisory abusive behaviours in organizations should also focus on empowering subordinates themselves not just on training supervisors.
  • Downsizings are particularly powerful triggers of abusive supervision as they enhance the vulnerability and exposure of submissive employees.
Keywords: Submissive employees; core self-evaluations; co-worker support; downsizing; abusive supervision; performance.

Despite awareness of noise aboard vessels at sea, few studies have reported measured noise levels aboard ships. This study aimed to describe the noise levels aboard vessels in the Royal Norwegian Navy (RNoN), and to assess the noise exposure of personnel aboard RNoN vessels. In 2012/2013 noise measurements were conducted aboard 14 RNoN vessels from four different vessel classes (frigates, coastal corvettes, mine vessels, and coast guard vessels) which were included in this study. Mean and median A-weighted noise levels (L p,A) in decibel (dB(A)) were calculated for different locations in each vessel class. The noise exposure of RNoN personnel was assessed by dosimeter measurements, and with a task-based (TB) strategy. The TB strategy used means of area measured noise levels in locations and the personnel’s mean reported time spent in the respective locations to estimate the exposure. Area measurements of noise during sailing with typical operating modes, showed that for all vessel classes the noise levels were high in engine rooms with median L p,A ranging from 86.4 to 105.3 dB(A). In all the other locations the vessel class with the highest noise levels (coastal corvettes) had a median L p,A ranging from 71.7 to 95.0 dB(A), while the vessel class with the lowest noise levels (coast guard vessels) had a median L p,A ranging from 41.5 to 57.8 dB(A). For all vessel classes the engineers and electricians had amongst the highest 24-hour noise exposure (L p,A,24h), both before and after adjusting for estimated use of hearing protective devices (L p,A,24h > 67.3 dB(A)). The vessel class with the highest personnel exposure levels (coastal corvettes) had L p,A,24h ranging from 76.6 to 79.3 dB(A). The vessel class with the lowest personnel exposure levels (coast guard vessels) had an L p,A,24h ranging from 47.4 to 67.3 dB(A). In general, the dosimeter measurements gave higher exposure levels than those estimated with the TB strategy. All vessel classes, except the coast guard vessels, had noise levels exceeding the RNoN standard’s recommended maximum noise levels. The area measured noise levels and the personnel’s exposure estimates indicate that navy personnel aboard RNoN vessels are at risk of acquiring adverse health effects from exposure to noise, and that a program to reduce the noise levels should be implemented.

Key words: navy, noise, noise exposure, sailor, ship, vessel.

A pleural mesothelioma arose in an employee of a wine farm whose work history shows an unusual occupational exposure to asbestos. The information, gathered directly from the case and from a work colleague, clarifies some aspects of the use of asbestos in the process of winemaking which has not been previously reported in such details. The man had worked as a winemaker from 1960 to 1988 in a farm, which in those years produced around 2500 hectoliters of wine per year, mostly white. The wine was filtered to remove impurities; the filter was created by dispersing in the wine asbestos fibers followed by diatomite while the wine was circulating several times and clogging a prefilter made of a dense stainless steel net. Chrysotile asbestos was the sole asbestos mineralogical variety used in these filters and exposure could occur during the phase of mixing dry fibers in the wine and during the filter replacement. A daily and annual time weighted average level of exposure and cumulative dose have been estimated in the absence of airborne asbestos fiber monitoring performed in that workplace. Since 1993, the Italian National Mesothelioma Register, an epidemiological surveillance system, has recorded eight cases with at least one work period spent as winemaker. Four of them never used asbestos filters and presented exposures during other work periods, the other four used asbestos filters but had also other exposures in other industrial divisions. For the information hitherto available, this is the first mesothelioma case with exclusive exposure in the job of winemaking.

Key words: asbestos exposure assessment, chrysotile, cumulative dose, exposure estimate, epidemiological surveillance, mesothelioma, past exposure, unusual asbestos exposure, wine filters.

Objectives: The task of grinding sandstone with a 5-inch angle grinder is a major source of exposure to respirable crystalline silica (RCS), known to cause diseases such as silicosis and lung cancer among workers who work with these materials. A shroud may be a suitable engineering control for this task. The objectives of this study were to evaluate the effectiveness of four commercially available shrouds at reducing respirable dust and RCS levels during the task of grinding sandstone using tools and accessories typical of restoration stone work.

Methods: The task of grinding sandstone with a 5-inch angle grinder, equipped with different grinding wheels, was carried out over three trials at a restoration stone masonry site. Photometric and RCS data were collected when a 5-inch grinder, equipped with different grinding wheels, was used to grind sandstone with and without a shroud. A total of 24 short duration samples were collected for each no shroud and with shroud combination. Worker feedback on the practicalities of each shroud evaluated was also collected.

Results: Respirable dust concentrations and RCS were both significantly lower (P < 0.001) when the grinders were equipped with a shroud compared with grinders without a shroud. Total geometric mean (GM) photometric respirable dust levels measured when grinding with a shroud were 0.5mg m-3, a reduction of 92% compared to grinding without a shroud (7.1mg m-3). The overall GM RCS concentrations were reduced by the use of a shroud by 99%. GM photometric exposure levels were highest when using the Hilti 5-inch diamond grinding cup and Diamond turbo cup and lowest when using the Corundum grinding point.

Conclusions: Concentrations of respirable dust and RCS can be significantly reduced by using commercially available shrouds while grinding sandstone with a 5-inch angle grinder in restoration stonework. The short-term photometric respirable dust and RCS measurements collected with and without a shroud indicate that dust and RCS concentrations are reduced by between 90 and 99%. Supplemental exposure controls such as respiratory protective equipment would be required to reduce worker 8-h time-weighted average RCS exposure to below the Scientific Committee on Occupational Exposure Limits recommended occupational exposure limit value of 0.05mg m-3 and the American Conference of Governmental Industrial Hygienists threshold limit value of 0.025mg m-3.

Key words: local exhaust ventilation, respirable dust, silica exposure.

The cost and complexity of commercially available whole-body vibration measurement devices is a barrier to the systematic collection of the information required to manage this hazard. The potential for a consumer electronic device to be used to estimate whole-body vibration was assessed by collecting 58 simultaneous pairs of acceleration measurements in three dimensions from a fifth-generation iPod Touch and gold standard whole-body vibration measurement devices, while a range of heavy mining equipment was operated at three surface coal mines. The results suggest that accelerometer data gathered from a consumer electronic device are able to be used to measure whole-body vibration amplitude with 95% confidence of ±0.06 m s-2 root mean square for the vertical direction (1.96 × standard deviation of the constant error).

Key words: consumer electronic device mi,ning equipment, whole-body vibration.

To protect the health of those occupationally exposed to respirable crystalline silica, the main industries in European Union associated with exposure to respirable silica, agreed on appropriate measures for the improvement of working conditions through the application of good practices, as part of ‘The Agreement on Workers Health Protection through the Good Handling and Use of Crystalline Silica and Products Containing it’ (NEPSI agreement), signed in April 2006. The present paper examines trends in exposure to respirable crystalline silica in Finland prior to and following the implementation of the NEPSI agreement and includes a working example of the NEPSI approach in the concrete industry. Data derived from workplace exposure assessments during the years 1994–2013 are presented, including 2556 air samples collected mostly indoors, from either the breathing zone of workers or from stationary points usually at a height of 1.5 m above the floor, with the aim to estimate average exposure of workers to respiratory crystalline silica during an 8-h working day. The aim was, to find out how effective this unique approach has been in the management of one of the major occupational hazards in the concerned industries. Application of good practices as described by the NEPSI agreement coincides with a strong decline in the exposure to respirable crystalline silica in Finnish workplaces, as represented by the clientele of Finnish Institute of Occupational Health. During the years followed in the present study, we see a >10-fold decrease in the average and median exposures to respirable silica. Prior to the implementation of the NEPSI agreement, >50% of the workplace measurements yielded results above the OEL8 h (0.2mg m−3). As of present (2013), circa 10% of the measurements are above of or identical to the OEL8 h (0.05mg m−3).

Key words: NEPSI agreement; quartz exposure; respirable crystalline silica.

This study aimed to explore the clinical characteristics of hand arm vibration syndrome (HAVS) in a group of tree fellers in a tropical environment. We examined all tree fellers and selected control subjects in a logging camp of central Sarawak for vibration exposure and presence of HAVS symptoms utilizing vibrotactile perception threshold test (VPT) and cold water provocation test (CWP). None of the subjects reported white finger. The tree fellers reported significantly higher prevalence of finger coldness as compared to the control subjects (OR=10.32, 95%CI=1.21–87.94). A lower finger skin temperature, longer fingernail capillary return time and higher VPT were observed among the tree fellers as compared to the control subjects in all fingers (effect size >0.5). The VPT following CWP of the tree fellers was significantly higher (repeated measures ANOVA p=0.002, partial ?2=0.196) than the control subject. The A (8) level was associated with finger tingling, numbness and dullness (effect size=0.983) and finger coldness (effect size=0.524) among the tree fellers. Finger coldness and finger tingling, numbness and dullness are important symptoms for HAVS in tropical environment that may indicate vascular and neurological damage due to hand-transmitted vibration exposure.

Key words: HAVS, Hand-transmitted vibration, Warm environment, Forestry, Cold provocation test.

In this report we describe a case of respiratory allergy induced by an unusual occupational exposure to rabbit. The patient worked as a part-time magician in theatres and private parties and the most popular performance of his show was to pull out a white rabbit from a top hat. Unfortunately, a few minutes after the extraction of rabbit from top hat, the patient experienced the onset of upper and lower airway symptoms, and in some occasions he was forced to stop the show and to use short acting ß2 agonists and intramuscular steroids. The results of SPT and evaluation of serological specific IgE (ImmunoCAP and ImmunoCAP ISAC IgE) revealed allergic sensitization to rabbit (Oryctolagus cuniculus) dander as well as to Parietaria and dust mites. ImmunoCAP ISAC IgE excluded allergic sensitization to other cross-reacting animal allergens. Rabbit constitutes a reliable risk factor for allergic sensitization in individuals working as professional / part-time magicians or as animators in some recreational settings (resorts, parties, charity shows, etc).

Summary statement: Rabbit constitutes a risk factor for occupational asthma in susceptible magicians.

These consensus guidelines provide recommendations for the safe handling of monoclonal antibodies. Definitive recommendations are given for the minimum safe handling requirements to protect healthcare personnel. The seven recommendations cover: (i) appropriate determinants for evaluating occupational exposure risk; (ii) occupational risk level compared with other hazardous and non-hazardous drugs; (iii) stratification of risk based on healthcare personnel factors; (iv) waste products; (v) interventions and safeguards; (vi) operational and clinical factors and (vii) handling recommendations. The seventh recommendation includes a risk assessment model and flow chart for institutions to consider and evaluate clinical and operational factors unique to individual healthcare services. These guidelines specifically evaluated monoclonal antibodies used in the Australian cancer clinical practice setting; however, the principles may be applicable to monoclonal antibodies used in non-cancer settings. The guidelines are only applicable to parenterally administered agents.

Keywords: cancer; monoclonal antibody; occupational health and safety; manufacturing; administration; consensus guideline.

This study assessed the present-day levels (year 2010–2011) of exposure to respirable dust (RD) and respirable silica (RS) in taconite mines and evaluated how the mining process influences exposure concentrations. Personal samples (n = 679) were collected to assess exposure levels of workers to RD and RS at six mines in the Mesabi Iron Range of Minnesota. The RD and RS concentrations were measured using the National Institute for Occupational Safety and Health (NIOSH) 0600 and NIOSH 7500, respectively. Between-mine, between-SEG (similar exposure groups), within-SEG, and within-worker components of variability for RD and RS exposures were estimated using a two- or three-way nested random-effects ANOVA model. The majority of RD concentrations across all mines were below the Mine Safety and Health Administration (MSHA) Permissible Exposure Limit (PEL). The highest concentrations of RD were often observed in either the Pelletizing or Crushing departments, which are inherently dusty operations. With a few exceptions, the concentrations of RS in the crushing and concentrating processes were higher than those in the other mining processes, as well as higher than the American Conference of Governmental Industrial Hygienists (ACGIH) Threshold Limit Value (TLV) for RS. The magnetic separation and flotation processes in the concentrating department reduced the levels of RS significantly, and lowered the percentage of quartz in RD in the pelletizing department. There was little variability among the six mines or between the two mineralogically distinct zones for either RD or RS exposures. The between-SEG variability for RS did not differ substantially across most of the mines and was a major component of exposure variance. The within-SEG (or between-worker) variance component was typically the smallest because in many instances one worker from a SEG within a mine was monitored multiple times. Some of these findings were affected by the degree of censoring in each SEG and mine, characteristics of the taconite rock, seasonal effects during sampling, or the tasks assigned to each job in that mine.

Keywords: Exposure assessment, respirable dust, respirable silica (quartz), taconite, variance components.
[Nota nuestra. La siguiente interrogante es considerada en la  TABLA DE ANTIJURIDICIDAD EN RELACIÓN A LA PREVENCIÓN DE SILICOSIS de nuestro libro de responsabilidad empresarial: ¿Se hace uso de las recomendaciones de lex artis en higiene para la medición del factor de riesgo sílice, señalándose la metodología empleada, y determinándose cómo el tipo de proceso minero de la empresa demandada influye en las concentraciones de exposición?
