Pressure vessels — including boilers, storage tanks, and industrial process equipment — are indispensable to modern industry but carry inherent risks if improperly designed, maintained, or operated. Failures can result in catastrophic explosions, toxic releases, or widespread service disruptions, with serious consequences for worker safety, public health, and infrastructure resilience. Regulation of pressure vessels is…

Aluminium is among the most widely used metals globally, valued for its light weight, versatility, and role in industries ranging from packaging and construction to transportation and consumer goods. Yet its ubiquity has also raised questions about potential health and environmental risks. Aluminium exposure can occur through food, water, consumer products, and occupational settings, and…

Titanium is valued for its strength, light weight, and corrosion resistance, making it indispensable in aerospace, medical devices, construction, and consumer goods. While titanium itself is generally considered safe, its extraction, processing, and use in certain forms raise potential health and environmental risks. Occupational exposures to titanium dusts and nanoparticles, as well as environmental impacts…

Country foods — the traditional foods harvested, hunted, or fished by Indigenous and rural communities — are central to cultural identity, nutrition, and food security. They provide essential nutrients, support community resilience, and reinforce connections to land and heritage. However, these foods can also present risks due to environmental contamination, overharvesting pressures, or changing ecosystems…

Artificial intelligence (AI) has become a transformative force in decision-making across sectors ranging from healthcare and finance to energy, transportation, and regulation. The promise of AI lies in its ability to process vast amounts of data quickly, uncover hidden patterns, and support evidence-informed decisions in ways that humans alone cannot easily achieve. Yet the risks…

Safe drinking water is a fundamental public health necessity. Contamination incidents — whether microbial, chemical, or physical — can rapidly undermine community trust and cause acute or long-term health harms. Challenges range from aging infrastructure and source water contamination to emerging contaminants such as pharmaceuticals, PFAS, and microplastics. Climate change further stresses water systems by…

Maternal health is a foundational determinant of population well-being, encompassing the safety and quality of care during pregnancy, childbirth, and the postpartum period. Despite medical advances, maternal morbidity and mortality remain pressing challenges in many regions, often reflecting inequities in access, socioeconomic conditions, and systemic gaps in healthcare delivery. Risks span direct causes such as…

Workplace products — from cleaning agents and solvents to industrial chemicals and nanomaterials — are essential to modern economies but can pose significant risks to worker health and safety. Risks include acute exposures causing burns or poisoning, as well as chronic risks such as cancer, respiratory disease, or reproductive effects. Beyond health, unsafe workplace products…

Nuclear energy is one of the most powerful and controversial sources of electricity in the modern world. It offers a low-carbon alternative to fossil fuels, supporting climate change mitigation, but also raises enduring concerns about reactor safety, radioactive waste, proliferation risks, and public trust. High-profile accidents, such as Chernobyl and Fukushima, have shaped global perceptions,…

Flooding is one of the most common and destructive natural hazards, affecting millions of people each year. Whether caused by heavy rainfall, snowmelt, storm surges, or river overflow, floods can result in loss of life, property damage, infrastructure failure, and long-term economic disruption. Climate change is intensifying flood risks by altering precipitation patterns, raising sea…
