Silica Exposure and Lung Health in Artificial Stone Workers: New Insights
July 16, 2024Understanding the Pathogenesis of Engineered Stone-Associated Silicosis
July 29, 2024The Background of Silicosis in MSEs
Silicosis, a debilitating and often fatal lung disease caused by the inhalation of respirable crystalline silica (RCS) dust, has become a significant occupational hazard for workers in micro or small-sized enterprises (MSEs) that fabricate engineered stone products.
Despite the severe health risks, data on workplace exposure to RCS among these workers are scarce, particularly in enterprises with a high percentage of overseas-born employees. This blog summarizes a comprehensive study conducted in Sydney, Australia, highlighting the urgent need for effective regulatory interventions and enhanced occupational health practices.
Insights from Sydney
A survey conducted by SafeWork NSW involved six engineered stone fabricating MSEs in Sydney, focusing on workers engaged in cutting, shaping, and polishing tasks. The study aimed to measure personal exposure to airborne RCS dust among 34 workers, observe their work practices, and record demographic information. The findings reveal alarming levels of RCS exposure, underscoring the critical need for improved workplace safety standards.
Key Findings on RCS Exposure
1. High Levels of RCS Exposure
The study found that 85% of workers performing dry tasks and 71% using water-fed tools were exposed to RCS dust levels exceeding the Australian Workplace Exposure Standard (WES) of 0.1 mg/m³ over an 8-hour time-weighted average. This significant exposure places these workers at high risk for developing silicosis.
2. Inadequate Dust Controls:
Dust control measures in the surveyed MSEs were found to be severely lacking. Ventilation systems were ineffective, and respiratory protection was either inadequate or improperly used. Many workers were not fit-tested for their respirators, reducing the protective efficacy of the equipment.
3. Vulnerable Workforce:
All sampled workers were overseas-born migrants, predominantly from Arabic, Chinese (Mandarin), and Vietnamese linguistic groups. This demographic factor, combined with limited awareness and training regarding the health hazards of RCS dust, exacerbates their vulnerability.
4. Lack of Health Monitoring
None of the workers had undergone health monitoring, including chest X-rays or lung function tests, which are crucial for early detection of silicosis. Additionally, most workers were unaware of the serious health risks posed by RCS exposure.
Implications for Regulatory Intervention
The findings from this study informed a comprehensive regulatory intervention program by SafeWork NSW, which included:
Hazard Communication
Development and dissemination of multilingual hazard communication tools to ensure workers understand the risks associated with RCS exposure.
Enhanced Dust Controls
Enforcing the implementation of effective dust control measures, such as local exhaust ventilation systems and proper use of water-fed tools.
Health Monitoring
Mandating health monitoring for workers exposed to RCS dust to facilitate early detection and prevention of silicosis.
Training and Education
Providing targeted training sessions for MSE operators and workers to promote safe work practices and compliance with safety standards.
Conclusion
The survey conducted in Sydney's engineered stone fabrication industry reveals a dire need for improved occupational health and safety measures to protect vulnerable workers from the risks of silicosis. The high levels of RCS exposure, inadequate dust control measures, and lack of health monitoring highlight the systemic issues within this industry, particularly for migrant workers.
Call for Intervention
Occupational health practitioners and regulators must address these challenges by implementing robust intervention programs that consider both workplace and demographic factors. This multifaceted approach can significantly reduce the risk of silicosis and other occupational illnesses, ensuring a safer and healthier work environment for all employees.
