Section 6390 Of Article 4. Duties From California Labor Code >> Division 5. >> Part 1. >> Chapter 2.5. >> Article 4.
6390
. The manufacturer of any hazardous substance listed pursuant
to the provisions of Section 6380 shall prepare and provide its
direct purchasers of the hazardous substance with an MSDS containing
the information specified in Section 6391 which, to the best of the
manufacturer's knowledge, is current, accurate, and complete, based
on information then reasonably available to the manufacturer. For
purposes of this section, a substance, mixture, or product shall not
be considered a hazardous substance if present in a physical state,
volume, or concentration for which there is no valid and substantial
evidence that any adverse acute or chronic risk to human health may
occur from exposure. The manufacturer shall revise an MSDS on a
timely basis as appropriate to the importance of any new information
which would affect the contents of the existing MSDS, and in any
event within one year of such information becoming available to the
manufacturer. If the new information indicates significantly
increased risks to, or measures necessary to protect, employee
health, as compared to those stated on the MSDS previously provided,
the manufacturer shall provide such new information to persons who
have purchased the product directly from the manufacturer within the
last year.
