WAC 296-800-18005
Preserve exposure records for at least 30
years. You must:
• Keep material safety data sheets (MSDSs) and analysis
using MSDSs for at least thirty years, including current, former,
and future employers receiving transferred records. Preserve
MSDSs in any form, as long as the information is not altered and
is retrievable. You may keep alternative records instead of
MSDSs concerning the identity of a substance. The alternative
record must also be kept for thirty years and contain the
following information:
– Some record of the identity (chemical name, if known) of a
substance or agent
– Where the substance or agent was used
– When the substance or agent was used
Note:
Keeping alternative records may be less work than you think. When developing your hazard communication program's list of
hazardous chemicals (WAC 296-800-17010), add the "where used" and "when used" information required by this rule.
