In the bustling industrial landscape of Singapore, a silent revolution is underway, driven by the increasing use of engineered nanomaterials. Among these, nano-titanium dioxide (nano-TiO2) stands out for its versatility and potential, but its widespread adoption has raised concerns about worker exposure and safety. A recent study, published in the journal ‘Academia Materials Science’ (translated from Latin as ‘Academy of Materials Science’), sheds light on the current practices and potential risks associated with nano-TiO2 use in Singapore, offering valuable insights for industries, particularly the energy sector.
The study, led by Sriram Prasath from the University of Newcastle School of Health Sciences in Australia, provides a comprehensive overview of nano-TiO2 usage trends, the forms in which it is used, and the number of workers potentially exposed to it. The research team conducted a cross-sectional survey among 65 companies identified as potentially involved with nanomaterials, with 11 companies participating in the study.
Nano-TiO2 is not just a buzzword; it’s a game-changer. It’s used in various forms—solid, powder, aerosol, or liquid—across diverse sectors, including research and development, manufacturing, and construction. In the energy sector, nano-TiO2 is used in solar cells, batteries, and fuel cells, enhancing their efficiency and longevity. However, with great power comes great responsibility.
The study found that monthly handling amounts of dry nano-TiO2 ranged from a mere 0.2 kg to a substantial 50 kg, with some companies using suspensions in even larger volumes. The number of workers potentially handling nano-TiO2 per company ranged from 2 to 20. These figures, while not alarming, underscore the need for proactive measures to ensure worker safety.
“Our findings highlight the need for robust occupational health and safety measures,” Prasath said. “As the field of nanotechnology continues to evolve, it’s crucial that industries stay ahead of the curve in terms of worker protection.”
The study’s implications are far-reaching. For the energy sector, understanding and mitigating the risks associated with nano-TiO2 use could pave the way for safer, more sustainable practices. It could also drive innovation in personal protective equipment (PPE) and workplace design, creating new commercial opportunities.
Moreover, the study serves as a wake-up call for industries to prioritize worker safety. It’s not just about compliance; it’s about creating a culture of safety that permeates every level of the organization. This is where the real value lies— in the well-being of workers and the long-term sustainability of businesses.
As Singapore continues to position itself as a global hub for innovation and technology, studies like this one will play a pivotal role in shaping the future of industries. They provide a roadmap for safe, sustainable growth, ensuring that the benefits of nanotechnology are realized without compromising worker health and safety. The findings of this study, published in ‘Academia Materials Science’, are a significant step in that direction.
