4. On page 50378, in column one, in the last line of text in that
column above footnote 17, the dollar amount of "$610 million" is
corrected to read "$621 million".
5. In Appendix A to Sec. 1910.1200 on page 50445, correct Table
A.1.1: Acute toxicity hazard categories and acute toxicity estimate
(ATE) values defining the respective categories, to read as follows:

---------------------------------------------------------------------------------------------------------
Oral (mg/kg bodyweight) See: <= 5....... > 5 and <= 50..... > 50 and <= 300... > 300 and <= 2000.
Notes (a), (b).
Dermal (mg/kg bodyweight) See: <= 50...... > 50 and <= 200... > 200 and <= 1000. > 1000 and <=
Notes (a), (b). 2000.
Inhalation--Gases (ppmV) See: <= 100..... > 100 and <= 500.. > 500 and <= 2500. > 2500 and <=
Note (a), Note (b), Note (c). 20000.
Inhalation--Vapors (mg/l) See: <= 0.5..... > 0.5 and <= 2.0.. > 2.0 and <= 10.0. > 10.0 and <=
Note (a), Note (b), Note (c), 20.0.
Note (d).
Inhalation--Dusts and Mists (mg/ <= 0.05.... > 0.05 and <= 0.5. > 0.5 and <= 1.0.. > 1.0 and <= 5.0.
l) See: Note (a), Note (b),
Note (c).
---------------------------------------------------------------------------------------------------------
Note: Gases concentration are expressed in parts per million per volume (ppmV).
Notes to Table A.1.1:
(a) The acute toxicity estimate (ATE) for the classification of a substance is derived using the LD50/LC50 where
available ;
(b) The acute toxicity estimate (ATE) for the classification of a substance or ingredient in a mixture is
derived using:
(i) the LD50/LC50 where available. Otherwise,
(ii) the appropriate conversion value from Table 1.2 that relates to the results of a range test, or
(iii) the appropriate conversion value from Table 1.2 that relates to a classification category;
(c) Inhalation cut-off values in the table are based on 4 hour testing exposures. Conversion of existing
inhalation toxicity data which has been generated according to 1 hour exposure is achieved by dividing by a
factor of 2 for gases and vapors and 4 for dusts and mists;
(d) For some chemicals the test atmosphere may consist of a vapor which is near the gaseous phase. In these
cases, classification is based on ppmV as follows: Category 1 (100 ppmV), Category 2 (500 ppmV), Category 3
(2500 ppmV), Category 4 (20000 ppmV).
The terms "dust," "mist," and "vapor" are defined as follows:
(i) Dust: solid particles of a substance or mixture suspended in a gas (usually air);
(ii) Mist: liquid droplets of a substance or mixture suspended in a gas (usually air);
(iii) Vapor: the gaseous form of a substance or mixture released from its liquid or solid state.
6. In Appendix A on page 50447, correct Table A.1.2: Conversion
from experimentally obtained acute toxicity range values (or acute
toxicity hazard categories) to acute toxicity point estimates for use
in the formulas for the classification of mixtures, to read as follows:
------------------------------------------------------------------------
Classification category
or experimentally Converted
Exposure routes obtained acute acute toxicity

50 < Category 2 <= 200. 50
200 < Category 3 <= 300

0.5 < Category 2 <= 2.0 0.5
2.0 < Category 3 <= 3

Note: Gases concentration are expressed in parts per million per volume
(ppmV).
7. In Appendix A on page 50450, correct Table A.2.3: Concentration
of ingredients of a mixture classified as skin Category 1 or 2 that
would trigger classification of the mixture as hazardous to skin
(Category 1 or 2), to read as follows:
------------------------------------------------------------------------
Concentration triggering
classification of a mixture as:
Sum of ingredients classified ---------------------------------------
as: Skin corrosive Skin irritant
Category 1 Category 2
------------------------------------------------------------------------
Skin Category 1................. >= 5%............. >= 1% but < 5%.
Skin Category 2................. .................. >=10%.
(10 x Skin Category 1) + Skin .................. >=10%.
Category 2.
------------------------------------------------------------------------
8. In Appendix A, on page 50467, correct Table A.7.1: Cut-off
values/concentration limits of ingredients of a mixture classified as
reproductive toxicants or for effects on or via lactation that trigger
classification of the mixture, to read as follows:
--------------------------------------------------------------------------------------------------------
Cut-off values/concentration limits triggering
classification of a mixture as:
-----------------------------------------------

Category 1 reproductive toxicant........................ >= 0.1% .............. ..............
Category 2 reproductive toxicant........................ .............. >= 0.1% ..............
Additional category for effects on or via lactation..... .............. .............. >= 0.1%
