According to the national standard "Chemical Safety Labels", the safety label uses a combination of words, graphic symbols and codes to indicate the dangers and safety precautions of chemicals.
Safety labels are pasted, hung and sprayed on packages or containers by production enterprises before the goods leave the factory. If the package is replaced, it will be re-pasted, hung and sprayed by the replacement unit.
Labels of containers or packages containing dangerous chemicals can only be removed after treatment and complete elimination of their dangers.
