Or. Admin. Code § 437-002-0364 - Oregon Rules for MOCA (4,4'-Methylene Bis (2-chloroaniline))
(1) Application.
This rule applies to any areas in which MOCA (4,4'-Methylene bis
(2-chloroaniline)) (CAS# 101-14-4) is manufactured, processed, repackaged,
released, handled, or stored, but shall not apply to transhipment in sealed
containers, except for the labeling requirements under OAR
437-002-0364(5)(b), (c), and
(d).
(2) Definitions:
"Absolute filter" is one capable of retaining 99.97 percent of a monodisperse aerosol of 0.3 µm particles.
"Administrator" means the Administrator of the Oregon Occupational Safety and Health Division, or any person directed to act for the Administrator.
"Authorized employee" means an employee whose duties require them to be in the regulated area and who has been specifically assigned by the employer.
"Clean change room" means a room where employees put on clean clothing and/or protective equipment in an environment free of MOCA. The clean change room shall be contiguous to and have an entry from a shower room, when the shower room facilities are otherwise required in this rule.
"Closed system" means an operation involving MOCA where containment prevents the release of MOCA into regulated areas, non-regulated areas, or the external environment.
"Decontamination" means the inactivation of MOCA or its safe disposal.
"Disposal" means the safe removal of MOCA from the work environment.
"Emergency" means an unforeseen circumstance or set of circumstances resulting in the release of MOCA which may result in exposure to or contact with MOCA.
"External environment" means any environment external to regulated and non-regulated areas.
"Isolated system" means a fully enclosed structure other than the vessel of containment of MOCA which is impervious to the passage of MOCA and which would prevent the entry of MOCA into regulated areas, non-regulated areas, or the external environment, should leakage or spillage from the vessel of containment occur.
"Laboratory type hood" is a device enclosed on three sides and the top and bottom, designed and maintained so as to draw air inward at an average linear face velocity of 150 feet per minute with a minimum of 125 feet per minute; designed, constructed, and maintained in such a way that an operation involving MOCA within the hood does not require the insertion of any portion of any employee's body other than their hands and arms.
"Non-regulated area" means any area under the control of the employer where entry and exit is neither restricted nor controlled.
"Open-vessel system" means an operation involving MOCA in an open vessel, which is not in an isolated system, a laboratory type hood, nor in any other system affording equivalent protection against the entry of MOCA into regulated areas, non-regulated areas, or the external environment.
"Protective clothing" means clothing designed to protect an employee against contact with or exposure to MOCA.
"Regulated area" means an area where entry and exit is restricted and controlled.

regulated area shall be established by an employer where MOCA is manufactured,
processed, used, repackaged, released, handled or stored. All such areas shall
be controlled in accordance with the requirements for the following category or
