OSHA Ergonomic Standards


Readopted by the Occupational Safety and Health Standards Board on April 17, 1997 Nonsubstantive "Clarity of Display" modifications submitted to OAL on May 16, 1997 Approved by OAL on June 3, 1997 Effective July 3, 1997 

June 3, 1997 New Release IR#97-31 

Add new Section 5110, Ergonomics to read:
Group 15, Occupational Noise and Ergonomics
Article 106, Ergonomics
Section 5110, Repetitive Motion Injuries 

(a) Scope and application. This section shall apply to a job, process, or 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) where 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 work 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 3, 1997.  Exemption: Employers with 9 or fewer employees. 

(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 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 employers is substantially certain to cause a greater reduction in such injuries and that this alternative measure would not impose additional unreasonable costs.
