[Explanatory Document] Designated Quantities and Storage Standards for Hazardous Materials
What is the designated quantity of hazardous materials? An explanation from the definition of categories to calculation and storage standards, including classifications abroad.
This document is a technical resource that explains the definitions of various categories, essential calculation methods for practical use, legal regulations based on storage quantities, practical operational methods, and differences from classifications overseas. The designated quantity of hazardous materials refers to the amount established by the Fire Service Act to regulate the storage and handling of hazardous materials in order to minimize the risk of fire. When storing or handling hazardous materials in quantities exceeding the designated amount, they must be managed at facilities that have received permission under the Fire Service Act. This document also introduces Zestron cleaning agents that are not subject to the Fire Service Act, which can help reduce the burden of managing hazardous materials. 【Contents】 ■ Definitions of various categories ■ Calculation methods ■ Legal regulations based on storage quantities ■ Practical operational methods ■ Differences from classifications overseas *For more details, please download the PDF or feel free to contact us.

Zestron is a global standard "flux cleaning agent manufacturer" based in Germany, with eight locations worldwide. Our cleaning agents are primarily environmentally friendly water-based cleaners that achieve a balance between cleaning performance and safety, while also enabling the reduction of organic solvents, VOCs, and overall usage to lower costs. At our technical center in Kanagawa, customers can choose from inline and batch-type spray cleaning equipment, as well as jet and ultrasonic devices, tailored to their needs, allowing them to test work cleaning under conditions equivalent to those in production environments. In parallel with the cleaning tests, we analyze cleanliness at our analysis center. Utilizing digital microscopes, FT-IR, ion chromatography, and SEM-EDX/EDS, we can detect flux residues that are often overlooked by visual inspection. After the tests are completed, our engineers will provide a technical report detailing recommended processes. *We generally offer support for cleaning process issues free of charge. If you have any requests or challenges related to flux cleaning, please feel free to contact us.
