Kumasaki Lab
Machine-translated · View original
A lab that studies how to prevent runaway chemical substances and ensure process safety.

AboutAbout the lab
Thinking about chemical safety, from reactions to management.
The Kumasaki Lab conducts research to prevent chemical substances and chemical reactions from running out of control and leading to explosions or other accidents.
Its work on safety and peace of mind ranges from hazard evaluation and effective use of high-energy materials, and analysis and prevention of runaway reactions, to methods for chemical process management and safety education.
Through experiments with chemical substances, simulations using computer software, and survey-based research, the lab considers the safety of entire systems involving multiple interacting factors.
On the lab's website, it is presented under the name "Process Safety Engineering Lab."
Key terms
- Runaway reaction
- A reaction that becomes uncontrollable. Some reactions accelerate as they generate heat, which can lead to accidents such as explosions
- Energetic material
- A substance that decomposes under slight stimuli such as heat, friction, or impact. Its decomposition instantly releases energy as heat, gas, or light
- Natech
- Industrial accidents triggered by natural disasters. Short for Natural and Technological Hazard

ResearchResearch themes
Chemical substances enrich our lives, but when a reaction becomes uncontrollable, it can have a major impact on society, including explosions. Through experiments, simulations, and survey-based research, this lab studies how to carry out chemical reactions safely without letting them run away, and how those reactions can be applied for a more prosperous society.
*Illustrative imageHazards of chemical processes and prevention measures
The lab investigates where hazards lie within chemical reaction processes, chemically analyzes reaction mechanisms, and examines measures to prevent fires and explosions. It also works on developing techniques that treat the likelihood of accidents probabilistically and contribute to risk assessment.
*Illustrative imageDesign and safe use of energetic materials
The lab studies energetic materials, which decompose under slight stimuli such as heat, friction, or impact. This includes designing and synthesizing the molecular structures of new materials and research on using them safely. It also proposes applications that take advantage of the materials' properties.
*Illustrative imageSafety management and Natech countermeasures
To reduce the risks inherent in complex systems such as chemical processes, the lab studies the development of methods to prevent the escalation of losses and the creation of guidelines for countering industrial accidents triggered by natural disasters (Natech). It also works on developing methods for safety education in chemical processes.
