I. Standardizing Label Content and Design
1. Clear and Eye-Catching Text: Use standard Chinese characters in a bold, legible font (e.g., boldface). The Chinese name should be positioned at the top of the label in a sufficiently large font size to ensure legibility from a distance of 1.5 meters.
2. High-Contrast Color Scheme: The text and background color should have a strong contrast, typically using black text on a white background or white text on a red background. Avoid printing light-colored text on a light-colored background.
3. Standardized Pictograms: Use pictograms as defined by the UN GHS (e.g., flames, skulls, corrosion icons, etc.). Symbols should be clear, with red borders, and a diameter no less than 1/3 of the label width.
II. Appropriate Material and Process Selection
1. Use waterproof, oil-proof, corrosion-resistant, and UV-resistant materials (e.g., PVC, aluminum composite panels, or polycarbonate sheets) to prevent fading and peeling due to moisture, friction, or sunlight. 2. Print clearly with a black border (≥1mm wide) and a ≥3mm blank margin to prevent information from being cut off or obscured.
3. It is recommended to use highly weather-resistant materials such as 3M Diamond Grade reflective film to ensure legibility in low-light or smoky conditions.
III. Correct Placement and Installation
1. Bottle/Barrel Packaging: Labels should be affixed to the side of the container, avoiding obstruction by handles or seals.
2. Box Packaging: Located in a prominent position on the end or side for easy viewing from multiple angles.
3. Bagged or Bundled Packaging: Securely fastened to a visible location to prevent detachment.
4. On the same work surface, ensure the complete combination of "Danger + Instruction + Emergency" information to avoid fragmented information.
IV. Regular Inspection and Maintenance
1. Establish a "Labeling Log," conduct daily inspections, and promptly replace damaged, faded, or detached labels.
Avoid using temporary "one-time" measures; ensure labels remain firmly attached during transportation and storage.
2. Labels should be updated promptly when the composition or hazards of chemicals change, and the update cycle should not exceed five years.
V. Digital Assistance to Enhance Readability
Encourage the use of QR codes on packaging that link to digital labels or Safety Data Sheets (SDS) to provide more detailed safety information. This information should be tamper-proof and allow for traceability of modification records.
