25258
. (a) A person shall not manufacture, sell, offer for sale, or
offer for promotional purposes in this state glass beads that
contain 75 parts per million (ppm) or more of arsenic or 100 ppm or
more of lead by weight, if those glass beads will be used with
pressure, suction, or wet- or dry-type blasting equipment.
(b) (1) The concentration of arsenic and lead shall be determined
in accordance with guidelines from EPA reference Method 3052 using
hydrofluoric acid (HF) for sample preparation or digestion.
(2) The digested sample shall be analyzed using an analytical
instrument recognized by EPA such as ICP-AES, ICP-MS, or other
recognized analytical instrument.
(3) The sample analysis method shall be capable of achieving
recovery within the method criteria limits of arsenic and lead. A
glass matrix reference material from, or traceable to, the National
Institute for Standards and Technology shall be used to verify lead
and arsenic concentrations specified in subdivision (a).
(4) The sample preparation method shall be capable of achieving
recovery within the method criteria limits of arsenic and lead from a
glass matrix reference standard from, or traceable to, the National
Institute for Standards and Technology containing the metals near the
concentrations specified in subdivision (a).
(c) Each container or bag of glass beads sold in this state for
surface preparation, including the cleaning, peening, finishing, and
deburring of aluminum and stainless steel products, and that will be
used with pressure, suction, or wet- or dry-type blasting equipment,
shall be labeled with the following:
