Subchapter 7. General Industry Safety Orders
Group 15. Occupational Noise
Article 106. Ergonomics
§5110. Repetitive Motion Injuries.
(a) Scope and application. This section shall
apply to a job, process, operation where a repetitive motion injury (RMI)
has occurred to more than one employee under the following conditions:
(1) Work related causation. The repetitive motion
injuries (RMIs) were predominantly caused (i.e. 50% or more) by a
repetitive job, process, or operation;
(2) Relationship between RMIs at the
workplace. The employees incurring the RMIs were performing a job process,
or operation of identical work activity. Identical work activity means
that the employees were performing the same repetitive motion task, such
as but not limited to word processing, assembly or, loading;
(3) Medical requirements. The RMIs were
musculoskeletal injuries that a licensed physician objectively identified
and diagnosed; and
(4)Time requirements. The RMIs were reported
by the employees to the employer in the last 12 months but not before July
- (b) Program designed to minimize RMIs. Every employer
subject to this section shall establish and implement a program designed
to minimize RMIs. The program shall include a worksite evaluation, control
of exposures which have caused RMIs and training of employees.
- (1) Worksite evaluation. Each job, process, or
operation of identical work activity covered by this section or a
representative number of such jobs, processes, or operations of identical
work activities shall be evaluated for exposures which have caused RMIs.
- (2) Control of exposures which have caused RMIs. Any
exposures that have caused RMIs shall, in a timely manner, be corrected or
if not capable of being corrected have the exposures minimized to the
extent feasible. The employer shall consider engineering controls, such as
work station redesign, adjustable fixtures or tool redesign, and
administrative controls, such as job rotation, work pacing or work breaks.
- (3) Training. Employees shall be provided training that
includes an explanation of:
(A) The employer's program;
(B) The exposures which have been associated with RMIs;
(C) The symptoms and consequences of injuries caused by repetitive motion;
(D) The importance of reporting symptoms and injuries to the employer; and
(E) Methods used by the employer to minimize RMIs.
(c) Satisfaction of an employer's obligation.
Measures implemented by an employer under subsection (b)(1), (b)(2), or (b)(3)
shall satisfy the employer's obligations under that respective subsection,
unless it is shown that a measure known to but not taken by the employer is
substantially certain to cause a greater reduction in such injuries and that
this alternative measure would not impose additional unreasonable costs.
