Periodic exposure evaluations

Exemption

Exemption:

  • Periodic exposure evaluations aren't required if exposure monitoring results conducted to fulfill requirments in Exposure evaluation, WAC 296-848-20060, are below the action level (AL).

You must

  • Obtain employee exposure monitoring results as specified in Table 2 by repeating Steps 2, 4, and 5 of the Exposure Evaluation Process found within this chapter, in Exposure evaluations, WAC 296-848-20060.

Note

Note:

  • If you document that one work shift consistently has higher exposure monitoring results than another for a particular operation, then you limit sample collection to the work shift with higher exposures and can use results to represent all employees performing the operation on other shifts.
Table 2

Periodic Exposure Evaluation Frequencies
If 8-hour employee exposure monitoring results: Then:
  • Are between the:
    • - Action level (AL) of 5 micrograms per cubic meter (µg/m3)
      and
    • - Permissible exposure limit (PEL) of 10 µg/m3.
    		•

    Conduct additional exposure evaluations at least every 6 months for the employees represented by the monitoring results.
    Are above the PEL Conduct additional exposure evaluations at least every 3 months for the employees represented by the monitoring results.
    • For employees previously above the PEL, have decreased:
      • - To a concentration between the PEL and AL
        and
      • - The decrease is demonstrated by 2 consecutive exposure evaluations made at least 7 days apart.
    		 You may decrease your evaluation frequency to every 6 months for the employees represented by the monitoring results.
    • Have decreased to below the AL
      and
    • The decrease is demonstrated by 2 consecutive exposure evaluations made at least 7 days apart.
    		 You may stop periodic employee exposure evaluations for employees represented by the monitoring results.

    Medical evaluations

    IMPORTANT:

    Medical evaluations conducted under this section will satisfy the medical evaluation requirement found in another chapter, Respirators, chapter
    296-842 WAC.

    You must

    • Make medical evaluations available to current employees who have been, are, or will be exposed to inorganic arsenic concentrations above the AL:
      • - At least 30 days in any 12-month period
        or
      • - A total of 10 years or more of combined employment with you or previous employers with at least 30 days of exposure per year.
    • Make medical evaluations available at no cost to employees.
      • - Pay all costs, including travel costs and wages associated with any time spent outside of the employee's normal work hours.
    • Make medical evaluations available at reasonable times and places.
    • Make medical evaluations available by completing Steps 1 through 6 of the Medical Evaluation Process for each employee covered.

     

    Note

    Note:

    • Employees who wear respirators need to be medically evaluated to make sure the respirator won't harm them, before they are assigned work in areas requiring respirators. Employees who decline to receive medical examination and testing to monitor for health effects caused by inorganic arsenic aren't excluded from receiving a separate medical evaluation for a respirator use.
    • If employers discourage participation in medical monitoring for health effects caused by inorganic arsenic, or in any way interfere with an employee's decision to continue with this program, this interference may represent unlawful discrimination under RCW 49.17.160, Discrimination against employee filing, instituting proceeding, or testifying prohibited--Procedure--Remedy.

    Helpful Tool

    Helpful Tool:

    Declination form for nonemergency related medical evaluations.

    You may use this optional form to document employee decisions to decline participation in the medical evaluation process for exposure to inorganic arsenic. To see this form, go to the Resources section within this chapter.

     

    Medical Evaluation Process

    Step 1: Identify employees who qualify, as stated above, for medical evaluations.

    Step 2a: Make medical evaluations available for employees identified in Step 1 at the following times:

      • Initially, when employees are assigned to work in an area where exposure monitoring results are, or will likely be, above the action level for at least 30 days in a 12-month period.
      • Periodically as specified in Table 3.
      • When employment with exposure ends, if the employee hasn't had an evaluation within the 6-month period before exposure ends. Include in these evaluations the same content as specified in Table 4 for initial evaluations, excluding a chest X ray.
    Table 3
    Frequencies for Periodic Medical Evaluations
    For: Provide periodic medical evaluations every:
    • Employees less than 45 years old with less than 10 years of exposure above the AL
    • 12 months
    • Employees 45 or older
      and
    • Employees with more than 10 years of exposure above the AL
    • 6 months
      and
    • 12 months to obtain a 14- by 17-inch posterior-anterior chest X ray for monitoring purposes, unless the LHCP has determined a different frequency for periodic X rays.

     

    Step 2b: Provide appropriate medical examination and emergency treatment when an employee identified in Step 1 develops signs or symptoms commonly associated with inorganic arsenic exposure.

    Step 3: Select a licensed healthcare professional (LHCP) who will conduct or supervise examinations and procedures.

    Step 4: Make sure the LHCP receives all of the following before the medical evaluation is performed:

    • A copy of:
      • - This chapter
    • A description of the duties of the employee being evaluated and how these duties relate to inorganic arsenic exposure.
    • The anticipated or representative exposure monitoring results for the employee being evaluated.
    • A description of the personal protective equipment (PPE) each employee being evaluated uses or will use.
    • Information from previous employment-related examinations when this information isn't available to the examining LHCP.
    • Instructions that the written opinions the LHCP provides you be limited to the following information:
      • - Results from examinations and tests.
      • - The LHCP's opinion about whether or not medical conditions were found that would increase the employee's risk for impairment from exposure to inorganic arsenic.
      • - Any recommended limitations for:
          • Inorganic arsenic exposure
            and
          • Use of respirators or other PPE
      • - A statement that the employee has been informed of medical results and medical conditions caused by inorganic arsenic exposure requiring further examination or treatment.

    Step 5: Make the medical evaluation available to the employee. Make sure it includes the content listed in Table 4, Content of Medical Evaluations.

    Step 6: Obtain the LHCP's written opinion for the employee's medical evaluation and give a copy to the employee.

      • Make sure the written opinion is limited to the information specified for written opinions in Step 4.

    Note

    Note:

    • If the written opinion contains specific findings or diagnoses unrelated to occupational exposure, send it back and obtain a revised version without the additional information.
