Rule 1.
(1) These
					 rules apply to all occupational exposures to methylenedianiline (MDA), Chemical
					 Abstracts Service Registry No. 101-77-9, except as provided in subrules (2) to
					 (7) of this rule.
(2) Except as
					 provided in subrule (8) of this rule and
					 29 CFR
					 1910.1050(e)(5), these rules
					 do not apply to the processing, use, and handling of products containing MDA if
					 initial monitoring indicates that the product is not capable of releasing MDA
					 in excess of the action level under the expected conditions of processing, use,
					 and handling that will cause the greatest possible release; and if no "dermal
					 exposure to MDA" can occur.
(3)
					 Except as provided in subrule (8) of this rule, these rules do not apply to the
					 processing, use, and handling of products containing MDA if objective data are
					 reasonably relied upon that demonstrate the product is not capable of releasing
					 MDA under the expected conditions of processing, use, and handling that will
					 cause the greatest possible release; and if no "dermal exposure to MDA" can
					 occur.
(4) These rules do not apply
					 to the storage, transportation, distribution or sale of MDA in intact
					 containers sealed in such a manner as to contain the MDA dusts, vapors, or
					 liquids, except for the provisions of
					 29 CFR
					 1910.1200 and 29 CFR 1910.1050(d).
(5) These rules do not apply to the
					 construction industry. Exposure to MDA in the construction industry is covered
					 by Construction Safety and Health Standard Part 605. "Methylenedianiline (MDA)
					 in Construction."
(6) Except as
					 provided in subrule (8) of this rule, these rules do not apply to materials in
					 any form that contain less than 0.1% MDA by weight or volume.
(7) Except as provided in subrule (8) of this
					 rule, these rules do not apply to "finished articles containing MDA."
(8) If products containing MDA are exempted
					 under subrules (2) to (7) of this rule, the employer shall maintain records of
					 the initial monitoring results or objective data supporting that exemption and
					 the basis for the employer's reliance on the data, as provided in the
					 recordkeeping provision of
					 29 CFR
					 1910.1050(n).
