Although varieties of organic rubber chemicals are used in the rubber industry, some of them are potentially harmful for human society and environment. In order to reduce such an environmental load caused by the release of chemical substances into the atmosphere, Japanese government has been establishing a series of laws and regulations concerning the manufacture, import, use and disposal of harmful chemical substances. These laws and regulations make the user of rubber chemicals easy to access the important information provided by the manufacturer concerning the hazards of the chemicals. As a result, users can make appropriate action for themselves and the environmental safety according to the individual circumstances.
