This colorful infographic presents an overview of essential investigation items for chemical substances, focusing on their safety and management. The central image shows hands holding green leaves surrounded by chemical flask icons, symbolizing chemical safety. Around the center are six sections with icons and Japanese text: product identification and usage, physicochemical properties (melting point, boiling point, vapor pressure, flash point), hazard classification with GHS labels, legal and regulatory information including REACH and GHS, and toxicity evaluation with animal and cellular imagery. The design uses bright blues, greens, oranges, and yellows to distinguish sections and includes molecular symbols and charts to emphasize scientific context.
