Current through Register 2024 Notice Reg. No. 28, July 12, 2024
(a) Scope.
This standard applies to all occupational exposures to
						  cadmium and cadmium compounds, in all forms, and in all industries except the
						  construction-related industries, which are covered under section
						  1532.
(b) Definitions.
Action level (AL) is defined as an airborne
						  concentration of cadmium of 2.5 micrograms per cubic meter of air (2.5
						  µg/m3), calculated as an 8-hour time-weighted
						  average (TWA).
Authorized person means any person authorized by the
						  employer and required by work duties to be present in regulated areas or any
						  person authorized by the Chief to be in regulated areas.
Chief means the Chief of the Division of Occupational
						  Safety and Health, or designee.
Emergency means any occurrence such as, but not limited
						  to, equipment failure, rupture of containers, or failure of control equipment
						  which results in an unexpected and potentially hazardous release of
						  Cadmium.
Employee exposure and similar language referring to the
						  air cadmium level to which an employee is exposed means the exposure to
						  airborne cadmium that would occur if the employee were not using respiratory
						  protective equipment.
Final medical determination is the written medical
						  opinion of the employee's health status by the examining physician under
						  subsections (
l
)(3)-(12) or, if multiple physician review under
						  subsection (
l
)(13) or the alternative physician determination
						  under subsection (
l
)(14) is invoked, it is the final, written
						  medical finding, recommendation or determination that emerges from that
						  process.
High-efficiency particulate air [HEPA] filter means a
						  filter capable of trapping and retaining at least 99.97 percent of
						  mono-dispersed particles of 0.3 micrometers in diameter.
NIOSH means the National Institute for Occupational
						  Safety and Health (NIOSH), U.S. Department of Health and Human Services, or
						  designee.
Regulated area means an area demarcated by the employer
						  where an employee's exposure to airborne concentrations of cadmium exceeds, or
						  can reasonably be expected to exceed the permissible exposure limit
						  (PEL).
(c) Permissible
						Exposure Limit (PEL).
The employer shall assure that no employee is exposed
						  to an airborne concentration of cadmium in excess of five micrograms per cubic
						  meter of air (5 µg/m3), calculated as an
						  eight-hour time-weighted average exposure (TWA).
(d) Exposure Monitoring.
(1) General.
(A) Each employer who has a workplace or work
						operation covered by this section shall determine if any employee may be
						exposed to cadmium at or above the action level.
(B) Determinations of employee exposure shall
						be made from breathing zone air samples that reflect the monitored employee's
						regular, daily 8-hour TWA exposure to cadmium.
(C) Eight-hour TWA exposures shall be
						determined for each employee on the basis of one or more personal breathing
						zone air samples reflecting full shift exposure on each shift, for each job
						classification, in each work area. Where several employees perform the same job
						tasks, in the same job classification, on the same shift, in the same work
						area, and the length, duration, and level of cadmium exposures are similar, an
						employer may sample a representative fraction of the employees instead of all
						employees in order to meet this requirement. In representative sampling, the
						employer shall sample the employee(s) expected to have the highest cadmium
						exposures.
