¢ The RQ for these hazardous substances is limited to those pieces of the metal having a diameter smaller than 100 microm-
eters (0.004 inches).
¢ The RQ for asbestos is limited to friable forms only.
@ Indicates that the name was added by PHMSA because (1) the name is a synonym for a specific hazardous substance and
(2) the name appears in the Hazardous Materials Table as a proper shipping name.
# To provide consistency with EPA regulations, two entries with different CAS numbers are provided. Refer to the EPA Table
302.4—List of Hazardous Substances and Reportable Quantities for an explanation of the two entries.
