摘要

The construction industry relies heavily on mineral resources, often extracted using explosives. However, safety studies and life cycle assessments (LCA) for activities involving explosives remain limited. This research addresses this gap by analyzing the manufacturing of Lead azide (LA), a key initiating explosive, integrating safety, and environmental assessments. The methodology applied preliminary hazard analysis (PHA) to evaluate risks and the OpenLCA software for LCAs, resulting in a life cycle inventory and an integrated decision matrix combining safety and environmental parameters. The study identified 12 risk scenarios, with only one classified as serious and none as high-risk. The LCA highlighted significant environmental impacts, and the decision matrix enabled scenario comparisons, supporting decision-making in explosive manufacturing. This research underscores the importance of integrating safety and LCA for enhanced risk management and sustainability in the explosives industry. It demonstrates the feasibility of open-source tools and proposes an innovative framework, addressing critical gaps in literature and applications in construction and defense.
