GHS Classification Guidance for the Japanese Government

Part4. Environmental Hazards Guidance
4-1 Information available for classification
4-1-1 Sources of Information available for classification
In UN GHS, available data are reviewed for classification.
In this guidance, procedures are shown below to reduce variations in classification results as much
as possible, while facilitating classification.
Upon conducting surveys for classification, review all of the acquired or accessible assessment
documents shown in List 1 and look for information on the relevant substances. If the selected
source provides no or insufficient information needed, search other information sources.
When the required information cannot be obtained from sources in List 1, repeat the process
with sources in List 2.
Examples of major information sources containing a general introduction or useful databases
are shown below. Information sources listed under each List are similar in reliability, but they may
vary in toxicity indexes and substances listed. This should not limit the use of reliable and useful
information sources other than those listed here.
Some on-line sites shown below revise posted information when appropriate, and acquiring the
latest information from them is preferable.
