I. Establish a Regular Inspection System
Inspection Frequency: It is recommended to inspect at least once a month. If the environment is harsh (e.g., humid, high temperature) or the chemicals are volatile, this can be reduced to once a week.
Inspection Content: Focus on checking whether the label is complete, whether the text/graphics are clear, whether the adhesion is firm, and whether the material is waterproof and durable.
II. Pay Attention to Key Details
Printing Quality: Text and background should have high contrast (e.g., black and white). Pictograms should meet standards (black symbols + white background + red border), with a border width ≥1mm and an outer margin of ≥3mm.
Affixing Location: Labels should be affixed to a conspicuous place on the packaging or container, such as the side of the drum/bottle, the end or side of the box, or a conspicuous place on the bag/bundle.
Material Durability: Labels must be waterproof and durable, and the adhesive must be firm to prevent detachment or damage during transportation and storage.
III. Address Problems Promptly
Damaged or Blurred Labels: Replace immediately to ensure the information is clearly legible.
Information Changes: Labels must be revised promptly when new hazards or changes in composition occur with the chemical.
IV. Other Precautions
Simplified Labeling: For small packages (≤100mL), the labeling can be simplified, but core information such as chemical identification, pictograms, and signal words must be retained.
Multi-Layer Packaging: Labels must be affixed to the inner packaging. If the outer packaging already has a label and the inner packaging label is transparent, an additional label is not required. If the outer packaging is opaque, the inner packaging label must be clearly visible.
