Going underground: Fatigue and sleepiness in tunnelling operations.

This research represents one of the first qualitative studies to investigate fatigue in the tunnelling sector of the construction industry. It explores the opinions of tunnellers and their managers about how fatigue influences or is influenced by tunnelling, and how this is managed. Fatigue and sleepiness were discussed in six focus groups with frontline workers (n = 42) and 10 manager interviews. Fatigue was seen to be a problem, with all participants having experienced, or recognised in others, the feeling of sleepiness whilst at work. Fatigue and sleepiness are not commonly discussed between tunnelling workers and they do not feel comfortable reporting instances of fatigue. The research shows that workers in the tunnelling construction sector are exposed to a wide range of occupational factors that potentially increase their vulnerability to fatigue, including the physical environment, repetitive and monotonous tasks, variable shift patterns and manual work. Additionally, personal factors such as social and family demands, long commute times and living away from home, can increase the risk of fatigue. The construction industry in general has gone some way to address fatigue and there is opportunity to further improve fatigue management. However, a major shift is needed before workers will feel able to openly discuss fatigue with their employer.

The use of actor-based immersive health and safety inductions: Lessons from the Thames Tideway Tunnel megaproject.

Health and safety inductions are ubiquitous in construction but tend to be poorly designed and suffer low levels of worker engagement. In this paper we report on the evaluation of an innovative, full day, actor-based health and safety induction called EPIC, currently being used on London's Thames Tideway Tunnel megaproject. As of March 2019, more than 14,000 individuals had attended EPIC. This evaluation examines the impact of EPIC from the perspective of participants and other stakeholders, and considers the utility of actor-based immersive health and safety inductions for use more widely, in both construction and other sectors. Using a mixed-method, longitudinal approach to data collection, EPIC is evaluated against Kirkpatrick's (1959) 'four levels' framework of reactions, learning, behaviour change and results. This paper discusses factors which support and hinder actor-based inductions, and the challenges involved in assessing the impact of inductions on subsequent behaviour and health and safety outcomes.

Injury Incidence, Prevalence and Severity in High-Level Male Youth Football: A Systematic Review.

BACKGROUND: At a young age, high-level youth footballers enter structured practice where they engage in regular training and matches. The academy system is considered fundamental to a young footballer's tactical, technical and physical development. Yet, with regular training and matches, high-level youth footballers may be exposed to the risk of injury. OBJECTIVE: This systematic review analyses and summarises published scientific information on high-level youth football injury characteristics and calculates the risk of them sustaining an injury over the course of a typical season. METHODS: The search was performed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Of the 1346 studies found, 23 fulfilled the inclusion criteria. RESULTS: Quality assurance scores for the selected research articles ranged between two and five out of eight. A high degree of heterogeneity between studies was observed. The probability of sustaining a time-loss injury during a high-level youth season ranged between < 1% and 96% for under 9- to under 16-year age groups and 50% and 91% for under 18- to under 21-year age groups. Pooled estimates for total (training and match) incidence per 1000 h was 5.8 for youth players aged under 9 to under 21 years, 7.9 for older players (under 17-under 21 years) and 3.7 for younger aged players (under 9-under 16 years). Training injury incidence rate ranged from 0.69 to 7.9 per 1000 h for all age groups in youth football. Match injury incidence rate for high-level youth players ranged from 0.4 to 80.0 per 1000 h. Close to one-fifth (18%) of all high-level youth football injuries were classified as severe and required > 28 days recovery time. Muscle strain injury accounted for 37% of all injuries reported in youth football. High probabilities (> 90%) of sustaining a time-loss injury over one typical high-level football season were found. CONCLUSION: High-level youth players lose large portions of the seasonal development to injury, with players seemingly suffering long absences from training and matches, consequently affecting health and well-being and possibly burdening club/parental finances and healthcare systems.

Accident data study of concrete construction companies' similarities and differences between qualified and non-qualified workers in Spain.

The aim of this paper is to discuss findings from an analysis of accidents in concrete construction companies in Spain and to compare the accident rates of qualified and non-qualified workers. A total of 125,021 accidents between 2003 and 2008 involving both blue-collar and white-collar workers were analysed, comparing the variables of occupation, age, company staff, length of service, location of the accident, together with the severity of the accidents. Results showed that lack of experience in the first month is more significant in non-qualified workers and experienced supervisors and that head injuries are more likely to lead to fatalities. The most remarkable similarity was that fatal accidents to and from the worksite are a problem common to both groups of workers.

The impact of occupational health and safety regulations on prevention through design in construction projects: Perspectives from Spain and the United Kingdom.

BACKGROUND: Since the mid-1990 s, Prevention through Design (PtD) has become increasingly prevalent in the built environment. The acceptance of PtD has largely been due to the removal or reduction of risks during the execution phase of construction projects. European States have had the added impetus of national legislation. OBJECTIVE: This paper analyzes the influence of European Union Directive 92/57/EEC on occupational safety and health injury prevention in the project design phase. METHODS: Qualitative methods comprised individual semi-structured interviews and focus groups with a panel of experts. Sixty individuals from construction and related professions (architects, engineers, constructors, developers, and other construction experts) answered 17 key questions to establish national perceptions of the effectiveness of Directive 92/57/EEC in Spain and the United Kingdom (UK). RESULTS: The implementation of PtD in the project design phase in the UK is clearer since the regulations explicitly state the obligations of project designers as well as those of the coordinator. Interviews with Spanish experts show that, in Spain, the prevention culture is less frequently realized. CONCLUSIONS: The most significant differences between the European Directive and national regulations which influence PtD are linked to the Health and Safety Coordinator, and Health and Safety documents.

Prevention of falls to a lower level: evaluation of an occupational health and safety intervention via subsidies for the replacement of scaffolding.

The objective of this study is to evaluate the impact of a subsidy policy for construction companies in Andalusia (Spain), which enables them to acquire new scaffolds. The rate of falls from scaffolds within the Andalusian construction sector in the period 2009-2011 was analysed. A randomised controlled trial was not possible as the subsidy was granted according to a public and competitive call. A quasi-experimental design based on an intervention group (subsidised companies) and a control group was chosen. Companies in the control group were selected from the social security census of companies in order to avoid selection bias. The subsidy policy has led to an overall 71% decrease in the rate of accident involving falls to a lower level in the companies that received grants in the period 2009-2011. The confidence interval for the comparison for the before-after difference in rates between the intervention group and the control group is found significant (confidence 95%, p = 0.05). The improvement of scaffolds was effective in reducing rates of accident with falls to a lower level. This intervention should be a priority in public policies. The process of standardisation of equipment with high accident risk should be developed further.

Safety risk assessment for vertical concrete formwork activities in civil engineering construction.

BACKGROUND: The construction sector has one of the worst occupational health and safety records in Europe. Of all construction tasks, formwork activities are associated with a high frequency of accidents and injuries. OBJECTIVE: This paper presents an investigation of the activities and related safety risks present in vertical formwork for in-situ concrete construction in the civil engineering sector. METHODS: Using the methodology of staticized groups, twelve activities and ten safety risks were identified and validated by experts. Every safety risk identified in this manner was quantified for each activity using binary methodology according to the frequency and severity scales developed in prior research. A panel of experts was selected according to the relevant literature on staticized groups. RESULTS: The results obtained show that the activities with the highest risk in vertical formwork tasks are: Plumbing and leveling of forms, cutting of material, handling materials with cranes, and climbing or descending ladders. The most dangerous health and safety risks detected were falls from height, cutting and overexertion. CONCLUSIONS: The research findings provide construction practitioners with further evidence of the hazardous activities associated with concrete formwork construction and a starting point for targeting worker health and safety programmes.

Analysis of construction accidents in Spain, 2003-2008.

INTRODUCTION: The research objective for this paper is to obtain a new extended and updated insight to the likely causes of construction accidents in Spain, in order to identify suitable mitigating actions. METHOD: The paper analyzes all construction sector accidents in Spain between 2003 and 2008. Ten variables were chosen and the influence of each variable is evaluated with respect to the severity of the accident. The descriptive analysis is based on a total of 1,163,178 accidents. RESULTS: Results showed that the severity of accidents was related to variables including age, CNAE (National Classification of Economic Activities) code, size of company, length of service, location of accident, day of the week, days of absence, deviation, injury, and climatic zones. CONCLUSIONS: According to data analyzed, a large company is not always necessarily safer than a small company in the aspect of fatal accidents, experienced workers do not have the best accident fatality rates, and accidents occurring away from the usual workplace had more severe consequences. IMPACT ON THE INDUSTRY: Results obtained in this paper can be used by companies in their occupational safety strategies, and in their safety training programs.

The interaction between design and occupier behaviour in the safety of new homes.

The design of new homes includes many safety features intended to protect occupiers from injury or ill health within the home, however the effectiveness of these primary intervention measures is likely to be affected by user behaviour. This study examined the interaction between user activity and dwelling design and how this might affect health and safety. It aimed to identify how people use features within new homes and how this may limit the protection afforded by building design, codes and regulations. Forty, home-based, semi-structured, in-depth interviews and home inspections were conducted with individuals recently inhabiting a new home. A range of behaviours were reported in relation to building features including fire doors, pipes and cables, and loft access, which may lead to increased risk of injury or ill-health. For example, occupiers described interfering with the self-closing mechanisms on fire doors and drilling into walls without considering the location of services. They also reported knowingly engaging in unsafe behaviour when accessing the loft, increasing their risk of falls. The accounts suggest that designers and builders need to give greater consideration to how occupier behaviour interacts with building features so that improvements in both design and occupier education can lead to improved health and safety.
