An upside-down fish next to a leafless tree and a flame over a circle are used in this system to designate aquatic toxicity and oxidizers.
A 2013 update to this standard includes a method where compounds are mixed with cellulose and the result is compared to mixtures of cellulose with calcium peroxide as a test for oxidizing potential. Unlike the IARC, this standard classifies only two categories of carcinogens, broken into known and suspected. An upside-down fish next to a leafless tree and a flame over a circle are used in this system to designate aquatic toxicity and oxidizers. Those (*) pictograms can be paired with the words "danger" or "warning." Ratings in this system are the inverse of those on the NFPA 704 diamond, meaning that low-hazard materials score a 4 in this system. For 10 points, name this system created by the UN for classification and labelling of chemicals that was incorporated into the Hazard Communication Standard in 2012, with final US implementation planned for 2015.
