WAC 296-848-40005
Exposure control plan.
IMPORTANT:
Use of employee rotation to control exposures is not
advisable since inorganic arsenic is a known carcinogen.
You must:
• Establish and implement a complete written exposure
control plan that includes at least the following, for
exposure control areas:
– A description of each operation releasing inorganic
arsenic, for example:
▪ Crew size.
▪ Current exposure controls.
▪ Materials processed.
▪ Machinery used.
▪ Operating procedures.
▪ Maintenance practices.
– Exposure evaluation data.
– A report of the technology considered for exposure
controls.
– Engineering plans and studies used as a basis for
selecting exposure controls.
– A detailed schedule for implementing:
▪ Feasible exposure controls, if immediate implementation
is not possible.
▪ Changes to enhance current exposure controls, when
necessary.
– An analysis of the effectiveness of the exposure
controls considered, when controls will not reduce exposures
to or below the permissible exposure limit (PEL).
– Other relevant information.
• Review and update your exposure control plan at least
every six months to keep it current.
• Implement exposure controls on the quickest schedule
feasible if controls will not reduce exposure to or below the
PEL.
• Provide a copy of your exposure control plan to
affected employees and their designated representatives, when
they ask to review or copy it.
