Oregon Administrative Rules › Chapter 437 - DEPARTMENT OF CONSUMER AND BUSINESS SERVICES, OREGON OCCUPATIONAL SAFETY AND HEALTH DIVISION › Division 2 - GENERAL OCCUPATIONAL SAFETY AND HEALTH RULES › Section 437-002-2025 - Definitions

Current through Register Vol. 63, No. 7, July 1, 2024
For the purposes of this subdivision the following definitions
				apply:
(1) Action level means a
			 concentration of airborne beryllium of 0.1 micrograms per cubic meter of air
			 (µg/m3), calculated as an 8-hour TWA.
(2) Airborne exposure and airborne exposure
			 to beryllium mean the exposure to airborne beryllium that would occur if the
			 employee were not using a respirator.
(3) Beryllium lymphocyte proliferation test
			 (BeLPT) means the measurement of blood lymphocyte proliferation in a laboratory
			 test when lymphocytes are challenged with a soluble beryllium salt.
(4) Beryllium work area means any work area
			 containing a process or operation that can release beryllium where employees
			 are, or can reasonably be expected to be, exposed to airborne beryllium at any
			 level or where there is the potential for dermal contact with beryllium.
(5) CBD diagnostic center means a
			 medical diagnostic center that has an on-site pulmonary specialist and on-site
			 facilities to perform a clinical evaluation for the presence of chronic
			 beryllium disease (CBD). This evaluation must include pulmonary function
			 testing (as outlined by the American Thoracic Society criteria),
			 bronchoalveolar lavage (BAL), and transbronchial biopsy. The CBD diagnostic
			 center must also have the capacity to transfer BAL samples to a laboratory for
			 appropriate diagnostic testing within 24 hours. The on-site pulmonary
			 specialist must be able to interpret the biopsy pathology and the BAL
			 diagnostic test results.
(6)
			 Chronic beryllium disease (CBD) means a chronic lung disease associated with
			 airborne exposure to beryllium.
(7) Competent person means an individual who
			 is capable of identifying existing and foreseeable beryllium hazards in the
			 workplace and who has authorization to take prompt corrective measures to
			 eliminate or minimize them. The competent person must have the knowledge and
			 ability necessary to fulfill the responsibilities set forth in this
			 subdivision.
(8) Confirmed
			 positive means the person tested has beryllium sensitization, as indicated by
			 two abnormal BeLPT test results, an abnormal and a borderline test result, or
			 three borderline test results. It also means the result of a more reliable and
			 accurate test indicating a person has been identified as having beryllium
			 sensitization.
(9) Emergency means
			 any uncontrolled release of airborne beryllium.
(10) High-efficiency particulate air [HEPA]
			 filter means a filter that is at least 99.97 percent efficient in removing
			 particles of 0.3 micrometers in diameter.
(11) Objective data means information, such
			 as air monitoring data from industry-wide surveys or calculations based on the
			 composition of a substance, demonstrating employee exposure to beryllium
			 associated with a particular product or material or a specific process, task,
			 or activity. The data must reflect workplace conditions closely resembling or
			 with a higher exposure potential than the processes, types of material, control
			 methods, work practices, and environmental conditions in the employer's current
			 operations.
(12) Permissible
			 exposure limit (PEL) means a concentration of airborne beryllium of 0.2
			 µg/m3, calculated as an 8-hour TWA.
(13) Physician or other licensed health care
			 professional [PLHCP] means an individual whose legally permitted scope of
			 practice (i.e., license, registration, or certification) allows him or her to
			 independently provide or be delegated the responsibility to provide some or all
			 of the particular health care services required by 437-002-2034.
(14) Regulated area means an area, including
			 temporary work areas where maintenance or non-routine tasks are performed,
			 where an employee's airborne exposure exceeds, or can reasonably be expected to
			 exceed, either the time-weighted average (TWA) permissible exposure limit (PEL)
			 or short term exposure limit (STEL).
