The prevalence of MSDs in the UK workforce is alarming. According to the Health and Safety Executive (HSE), approximately 477,000 workers suffer from work-related MSDs, leading to 7 million lost working days annually. This accounts for nearly a quarter of all work-related health absences.
The rail sector, however, faces an even greater challenge. The Office of Rail and Road (ORR) has identified MSDs as major contributors to industry sickness absence. The Rail Safety and Standards Board (RSSB) reported a Lost Time Rate of 4.28% in 2019, surpassing national averages. MSDs, along with mental health issues, are responsible for about 25% of sickness absence days in the rail sector.
3. Occupational Risk Analysis: Job Roles Impacted
Different roles within the rail industry face varying levels of MSD risk:
Track Maintenance Workers: Heavy lifting and awkward postures contribute to back injuries and upper extremity disorders.
Construction Workers: Manual material handling in rail infrastructure projects poses significant MSD risks.
Signallers and Controllers: Static postures and repetitive tasks can lead to upper limb disorders and neck strain.
Train Maintenance Staff: Working in confined spaces, performing repetitive tasks, and handling heavy equipment can lead to various MSDs. Common issues include back strain from awkward postures, shoulder and arm problems from overhead work, and knee injuries from kneeling or squatting.
Shunters: Coupling and uncoupling train cars, operating switches, and climbing on and off moving equipment can lead to back injuries, strains, and sprains due to the physical nature of the work
Cleaning Staff: Repetitive motions, awkward postures, and use of cleaning equipment can lead to various MSDs. Common issues include back strain from bending and lifting, shoulder and arm problems from repetitive cleaning motions, and knee injuries from frequent kneeling or squatting. Working in confined spaces on trains or in stations can exacerbate these risks.
Station Staff: Luggage handling and passenger assistance contribute to back and shoulder problems.
Train Conductors: Frequent movement through train carriages, ticket checking, and assisting passengers can lead to lower back strain and repetitive motion injuries.
Train Hosts: Like conductors, they may experience MSDs from constant movement and passenger assistance tasks.
Catering Staff: Pushing heavy trolleys, repetitive serving motions, and working in confined spaces on moving trains can contribute to various MSDs, particularly in the back, shoulders, and arms.
Train Drivers: Prolonged sitting and repetitive actions increase the risk of back pain and upper limb disorders. Note, the UK rail industry has conducted substantial work on cab ergonomics that aims to address historical issues with train cab design and improve drivers' working conditions.
These job-specific risks highlight the need for targeted interventions. The diverse nature of these roles, from stationary positions to highly mobile tasks, underscores the complexity of addressing MSDs in the rail industry.
4. Multifaceted Challenges in MSD Management
4.1 Demographic Shift: Aging Workforce
The rail industry is facing a demographic challenge. With 28% of rail workers aged 51 and over, and nearly 15,000 employees potentially retiring by 2025, the sector must address the increased MSD susceptibility of its aging workforce. This demographic shift also threatens to deplete the industry of experienced workers, potentially exacerbating MSD risks.
4.2 Workforce Composition: Subcontractor Prevalence
The industry's reliance on subcontractors, especially for manual labour, introduces additional complexities. Subcontractors may receive inconsistent training in MSD prevention, and their transient nature can lead to underreporting of MSD-related issues. This challenge underscores the need for industry-wide standards and training programs
4.3 Methodological Challenges in Risk Assessment
Conducting comprehensive MSD risk assessments in the rail industry is complicated by the diverse and dynamic nature of rail operations. From confined spaces to open-air settings, each environment presents unique ergonomic challenges. This variability necessitates adaptive assessment strategies.
