Item Restricted An Analysis of Laws Safeguarding Healthcare Workers in the United Kingdom(Saudi Digital Library, 2025) Aleniz, Fahad; Brodeala, ElenaThis study analyzed laws safeguarding healthcare workers in the UK. The objective was to understand the legal, health, and safety standards protecting UK healthcare workers and assess employees’ challenges before identifying required reforms. The study results revealed that the UK had initially focused on industry-specific laws to promote employee safety. However, changes in employment composition had adjusted the approach, resulting in the focus on occupational health and safety. Healthcare workers in the UK found legal reprieve from a variety of laws, including HASAWA (1974), Workplace Health and Safety (1992), Provision and Use of Work Equipment Regulations (1992), Manual Handling Operations Regulations (1992), Display Screen Equipment Regulations 1992, and Personal Protective Equipment Regulations (1992, 2018, and 2022). The challenge of the UK’s employee safety legal regime was an inadequate risk-based model downgrading severe risks healthcare workers routinely faced. The implication of this study was the need for reforms focusing on regulator funding, modernization of the regulatory regime, monitoring, and enforcement.2 0Item Restricted Environmental Impact of Personal Protective Equipment in Dental Services During COVID-19: A Life Cycle Assessment Approach(Trinity College Dublin - The University of Dublin, 2025) Almutairi, Waleed; Duane, BrettObjectives COVID-19 has significantly influenced Personal Protective Equipment (PPE) use in dental services. This study quantifies the environmental impact of different PPE types used at Dublin Dental University Hospital (DDUH). Methods A life cycle assessment was conducted to evaluate PPE used at DDUH in 2020/2021. PPE were categorized as: 1. Body protection: Disposable and reusable gowns. 2. Eye protection: Visor with a disposable face shield and reusable visor. 3. Respiratory protection: FP2SLw respirator, FFP2 respirator, and surgical mask. An environmental impact assessment was performed using OpenLCA (version 1.10.3) with the ecoinvent_37_cutoff database. Processes included manufacturing, packaging, transportation, and disposal, with an additional washing step for reusable gowns. The functional unit was one PPE product used for a single clinical visit. Results Body protection PPE had the highest environmental impact, with reusable gowns consuming more water (4.74E-07 DALY) than disposable gowns (9.47E-08 DALY). However, climate change impact was greater for disposable gowns (3.99E-07 DALY vs. 1.99E-07 DALY). In eye protection, visors with disposable face shields had a higher impact than reusable visors, emitting five times more CO₂-equivalent and consuming four times more water. Climate change-related damage was also higher (3.03E-07 vs. 5.89E-08 DALY). For respiratory protection, the FP2SLw respirator had the highest burden, followed by the FFP2 respirator and surgical mask. Global warming impact was highest for the FP2SLw respirator (7.92E-08 DALY), while water consumption impact was greatest for the FP2SLw (1.65E-08 DALY) and lowest for the surgical mask (3.84E-09 DALY). Conclusions Reducing PPE's environmental impact requires prioritizing locally made, reusable, and recyclable materials. Disposable gowns were preferable to reusable gowns due to their lower environmental burden, but a lightweight polyester alternative could be more sustainable. Reusable visors outperformed disposable face shield visors. For respiratory protection, the FP2SLw and FFP2 respirators have the same filtration capacity. However, the FFP2 respirator, manufactured in Ireland, is lighter and has a lower environmental impact, making it the preferred option. When high filtration performance is not required, the surgical mask is the most environmentally sustainable choice among respiratory PPE.8 0
