Abstract

Background
Cleaning product use has been associated with adverse respiratory health effects such as asthma in cleaning staff and healthcare workers. Research in health effects from cleaning products has largely depended upon collecting exposure information by questionnaires which has limitations such as recall bias and underestimation of exposure. The aim of this study was to develop a Cleaning and Hazardous Products Exposure Logging (CHaPEL) app with a barcode scanner and to test the feasibility of this app with university cleaners.


Methods
The CHaPEL app was developed to collect information on demographics, individual product information, and exposure information. It also included an ease-of-use survey. A pilot study with university cleaning workers was undertaken in which cleaning workers scanned each product after use and answered the survey. Respiratory hazards of cleaning substances in the scanned cleaning products were screened by safety data sheets, a Quantitative Structure-Activity Relationship model and an asthmagen list established by an expert group in the US.


Results
Eighteen university cleaners participated in this study over a period of 5 weeks. In total, 77 survey responses and 6 cleaning products were collected and all reported that using the app was easy. The most frequently used product was a multi-surface cleaner followed by a disinfectant. Out of 14 substances in cleaning products, ethanolamine and Alkyl (C12-16) dimethyl benzyl ammonium chloride were found as respiratory hazardous substances.


Conclusion
The CHaPEL app is a user-friendly immediate way to successfully collect exposure information using the barcodes of cleaning products. This tool could be useful for future epidemiological studies focused on exposure assessment with less interruption to the workers.

Abstract
Estimates of occupational disease burden provide important information on which effective policy and regulations can be developed. However, there is no direct way that these data can be obtained, and most burden estimates are derived by merging different data from diverse sources to synthesize estimates of the number of people made ill or who have died from workplace exposures. In recent years, several research groups have published estimates of occupational health burden at national or global scales; these are not always consistent. The World Health Organisation and the International Labour Organisation have taken on the task of producing occupational disease burden estimates for several workplace agents, which we assume are to be seen as the definitive global, regional, and national data. In this commentary, we critique the WHO/ILO approach for their estimates of the non-melanoma skin cancer burden from solar ultraviolet radiation and some of their results for hazardous particulates. We provide recommendations for researchers undertaking occupational burden estimates that they should report along with their data.

Abstract
The oil and gas industry in Nigeria poses significant health risks to its workers due to exposure to crude oil and petroleum products during various processes. To ensure worker safety and health, the Respiratory Protection Program (RPP) is essential. However, past studies have identified a knowledge-practice gap leading to inadequate safety practices.
This study aims to assess the RPPs in Nigeria's oil and gas industry by evaluating workers' knowledge, awareness, behaviour, and compliance regarding respiratory protection while aligning with the hierarchy of controls. It has four main objectives:
Assess the overall control program in reducing respiratory hazards, following the hierarchy of control.
Evaluate the functional and effective elements of the RPP in Nigeria's oil and gas industry.
Determine if knowledge and awareness of respiratory protection vary by location or processes.
Evaluate employee compliance with the RPP.
The study will employ a mixed-method approach, combining open-ended qualitative data collected through interviews with industrial hygienists and numerical quantitative data obtained from questionnaire surveys of health and safety officers and workers in selected oil and gas companies. The COM-B (Capability, Opportunity, and Motivation - Behavior) model will guide the development of questions for both approaches.
The findings aim to identify the strengths and weaknesses of the current RPP, offering insights for improvement. This will significantly enhance occupational health and safety practices within the Nigerian oil and gas industry. Notably, this study is groundbreaking in Nigeria, as it utilizes the COM-B model to examine the behaviour of oil and gas workers in complying with respiratory protection measures, making it a pioneering effort in this field.

Abstract
This study aimed to examine if role and rank were important determinants of exposures to traumatic events and psychosocial risk factors for UK police officers and staff. We used self-reported data on job profile (rank, role), demographics (age, gender) and psychosocial and other risk factors available from 'The Job and Life' 2018 survey of 15,202 UK police officers and staff. Random effect models were used to investigate the explained variability in the reported exposure of: job quality, traumatic experiences, workplace support, working hours, and handling/contact with potentially infectious materials (e.g. bodily fluids) by rank (5 categories), role (10 or 22 categories), gender (3 categories), age (4 categories) and the combination of these variables. Using job role, the explained variance of traumatic experiences, exposure to infectious material and job quality ranged from 10 to 27%, whereas a combined grouping using role, rank and age accounted for >35% of the total variance of work-life balance. Rank was important for working hours, explaining ~49% of the total variance. Gender and age accounted for ≤ 8% of the total variance for all exposures. These findings suggest that among police officers and staff, the role is an important predictor of exposure to psychosocial and infectious risk factors. These results will be used to develop job exposure matrices that can be employed to investigate the link between these risk factors and health outcomes in the AIRWAVE study, which is a longitudinal study of the UK police workforce.

Abstract

Objectives
When it comes to controlling workplace transmission of SARS-CoV-2, the virus that causes COVID-19, different workplaces and industrial sectors face different challenges, both in terms of likely transmission routes and which control measures can be practically, economically, and effectively implemented. This article considers a large body of research in the United Kingdom across different work sectors and time points during the COVID-19 pandemic to better understand mitigation measures, challenges to mitigating the risk of SARS-COV-2 transmission, knowledge gaps, and barriers and enablers to control viral transmission.


Methods
Data is drawn from 2 phases of research. Phase 1 gathered data from an interactive workshop (April 2022) where PROTECT researchers working across 8 work sectors shared knowledge and expertise from research conducted between 2020 and 2022. Phase 2 revisited 6 of these sectors to explore participants' views on the "living with COVID" phase of the pandemic (February–October 2022) through qualitative interviews.


Results
Our findings emphasise the importance of considering the characteristics of each work sector (and their sub-sectors), relative to the physical workplace and workforce, the ways organisations operate, and how they interact with the public. Study findings show that participant's views and organisational practices changed quickly and significantly over the course of the pandemic. Most participants initially perceived that the majority of risk mitigations would remain in place for the foreseeable future. However, following the change in Government Guidance towards "living with COVID", most mitigation measures were quickly removed and it had become necessary for sectors/organisations to restore normal operations, thereby treating the COVID-19 virus like any other illness, while remaining prepared for future health emergencies that may arise.


Conclusion
We suggest that national policy makers and organisational leaders remain mindful of the lessons learned and knowledge gained at all levels (national, regional, local, organisational, and individual) during the COVID-19 pandemic. We make recommendations in support of recovery as sectors/organisations continue "living with COVID" and other respiratory diseases; balanced with longer term planning for the next public health crisis.

Abstract

Background
Age-standardized mortality rates for taxi drivers, chauffeurs, bus and coach drivers show that public transport workers were at high risk at the beginning of the COVID-19 pandemic. Nevertheless, the public transport sector was required to continue services throughout the pandemic.


Objectives
This paper aims to develop a better understanding of the experiences of organizational leaders and workers within the UK public transport sector (bus, rail, and tram). Specifically, it aims to explore the perceived balance of risk and mitigation of SARS-CoV-2 transmission, report on their perceptions of safety in public transport during the pandemic and in the future, and consider how these perceptions and changes impact on long-term worker health and wellbeing.


Methods
This study formed part of a larger stakeholder engagement with the public transport sector. Organizational leaders and workers were recruited (n = 18) and semi-structured interviews carried out between January and May 2021. Data were analysed thematically.


Results
Overarching and subthemes were identified. Themes relating to perceptions and impacts of risk of COVID-19 for employees included: acceptability of risk for workers, perceptions of risk mitigation effectiveness, changes to working practices and their impact on morale and wellbeing, issues with compliance to mitigations such as social distancing and face coverings in passenger and co-worker groups alongside a lack of power to challenge behaviour effectively, and the roles of leadership and messaging. Themes related to long-lasting impacts of COVID-19 on working practices and effects on health and wellbeing included: continuing mitigations, impact of increasing passenger numbers, impact of vaccination programme, and impact of changes to business structure.


Conclusions
Most public transport employees reported feeling safe, related to the extent to which their role was public-facing. However, data were collected during a time of very low passenger numbers. Current mitigation measures were thought effective in reducing the risk of viral transmission, although measures may have a detrimental effect on worker morale and wellbeing. Issues relating to non-compliance with guidance and 'in-group' behaviour were identified. Impacts on wider business sustainability and individual wellbeing of staff should be considered when developing responses to any future pandemics. Recommendations are made for prioritizing employee engagement with colleagues, and the importance of strong leadership and clear messaging in promoting adherence to behavioural mitigations.

Abstract

Objectives
Food processing facilities represent critical infrastructure that have stayed open during much of the COVID-19 pandemic. Understanding the burden of COVID-19 in this sector is thus important to help reduce the potential for workplace infection in future outbreaks.


Methods
We undertook a workplace survey in the UK food and drink processing sector and collected information on workplace size, characteristics (e.g. temperature, ventilation), and experience with COVID-19 (e.g. numbers of positive cases). For each site, we calculated COVID-19 case rates per month per 1000 workers. We performed an ecological analysis using negative binomial regression to assess the association between COVID-19 rates and workplace and local risk factors.


Results
Respondents from 33 companies including 66 individual sites completed the survey. COVID-19 cases were reported from the start of the pandemic up to June 2021. Respondents represented a range of industry subgroups, including grain milling/storage (n = 16), manufacture of malt (n = 14), manufacture of prepared meals (n = 12), manufacture of beverages (n = 8), distilling (n = 5), manufacture of baked goods (n = 5), and other (n = 6), with a total of 15 563 workers across all sites. Average monthly case rates per 1000 workers ranged from 0.9 in distilling to 6.1 in grain milling/storage. Incidence rate ratios were partially attenuated after adjusting for several local and workplace factors, though risks for one subgroup (grain milling/storage) remained elevated. Certain local and workplace characteristics were related to higher infection rates, such as higher deprivation (5 km only), a lower proportion of remote workers, lower proportion of workers in close proximity, and higher numbers of workers overall.


Conclusions
Our analysis suggests some heterogeneity in the rates of COVID-19 across sectors of the UK food and drink processing industry. Infection rates were associated with deprivation, the proportions of remote workers and workers in close proximity, and the number of workers.

Abstract
Harmonized tools and approaches for data collection can help to detect similarities and differences within and between countries and support the development, implementation, and assessment of effective and consistent preventive strategies. We developed open source occupational questionnaires on COVID-19 within COVID-19 working groups in the OMEGA-NET COST action (Network on the Coordination and Harmonisation of European Occupational Cohorts, omeganetcohorts.eu), and the EU funded EPHOR project (Exposome project for health and occupational research, ephor-project.eu). We defined domains to be included in order to cover key working life aspects of the COVID-19 pandemic. Where possible, we selected questionnaire items and instruments from existing questionnaire resources. Both a general occupational COVID-19 questionnaire and a specific occupational COVID-19 questionnaire are available. The general occupational COVID-19 questionnaire covers key working life aspects of the COVID-19 pandemic, including the domains: COVID-19 diagnosis and prevention, Health and demographics, Use of personal protective equipment and face covering, Health effects, Work-related effects (e.g. change in work schedule and work–life balance), Financial effects, Work-based risk factors (e.g. physical distancing, contact with COVID-19-infected persons), Psychosocial risk factors, Lifestyle risk factors, and Personal evaluation of the impact of COVID-19. For each domain, additional questions are available. The specific occupational COVID-19 questionnaire focusses on occupational risk factors and mitigating factors for SARS-CoV2 infection and COVID-19 disease and includes questions about the type of job, amount of home working, social distancing, human contact (colleagues, patients, and members of the public), commuting, and use of personal protective equipment and face coverings. The strength of this initiative is the broad working life approach to various important issues related to SARS-CoV-2 infection, COVID-19 disease, and potentially future pandemics. It requires further work to validate the questionnaires, and we welcome collaboration with researchers willing to do this. A limitation is the moderate number of questions for each of the domains in the general questionnaire. Only few questions on general core information like ethnicity, demographics, lifestyle factors, and general health status are included, but the OMEGA-NET questionnaires can be integrated in existing questionnaires about sociodemographic and health-related aspects. The questionnaires are freely accessible from the OMEGA-NET and the EPHOR homepages.

Abstract

Objectives
The processing of seafood (fish and shellfish) for human consumption can lead to health consequences, including occupational asthma (OA). Several non-UK studies have reported both respiratory outcomes and airborne levels of major allergens in seafood processing. However, there is a paucity of such evidence in the UK land-based seafood processing sector, which employs some 20 000 workers.


Methods
University of Manchester's Surveillance of Work-related and Occupational Respiratory Disease (SWORD) reporting system has been interrogated over the period 1992–2017 to define the incidence rate of OA cases that can be ascribed to the UK land-based processing sector, and the seafood species implicated. Airborne allergen monitoring data undertaken at Health and Safety Executive's laboratory from 2003 to 2019 have also been collated.


Results
The estimated annual OA incidence rate in seafood processors was 70 [95% confidence intervals (CIs) 48.9, 91.1] per 100 000 workers compared with 2.9 (95% CIs 2.8, 3.1) in 'all other industries'. The annual calculated percentage trend in OA (1992–2017) was −8.1% (95% CIs −15.9, 0.4) in seafood processing showing a similar trend to 'all other industries' (mean −7.0%; 95% CIs −7.8, −6.1). Prawns and salmon/trout were notably implicated by SWORD as causative species related to OA. There is a general paucity of available UK airborne allergen monitoring data, particularly concerning processing salmon or trout. Available airborne monitoring for salmon parvalbumin in seven processors ranged between the limit of detection and 816 ng m−3 (n = 64). Available air monitoring levels of the major shellfish allergen (tropomyosin) during processing of crabs and prawns ranged between 1 and 101 600 ng m−3 (n = 280), highlighting that high levels of exposure can occur.


Conclusions
These data show an excess incidence of OA in the UK seafood processing industry during 1992–2017, with limited airborne monitoring data for the processing of prawn, crab, and salmon suggesting that significant exposure to major seafood allergens can occur in this industry. Further investigation of current levels of respiratory ill-health and the sources of allergen exposure are warranted.
