--Table VIII-1. -- Methylene Chloride Application Groups--
osha-slc.gov
Chapter II of the economic analysis describes the uses of methylene
chloride and the industries in which such use occurs. Employee
exposures to MC are analyzed on the basis of "application groups,"
i.e., groups of firms that use MC to perform a particular function,
such as metal cleaning or industrial paint stripping, regardless of
the particular industry in which the use takes place. The methodology
used by OSHA in the analysis is appropriate when a ubiquitous chemical
like MC is used to perform the same function in many kinds of firms in
many industries, because the processes used, employee exposures
generated, and controls in place or needed to achieve compliance are
the same, whether the process takes place in a machine shop, on board
ship, or on a construction site. For example, because the process of
using MC to strip paint or coatings from an object is essentially the
same whether the object being stripped is a spray paint booth, boat,
church pew, or automobile, and the exposures generated during the
process are similar in important respects, it is appropriate to
analyze such activities as a group. However, OSHA's technological
feasibility and cost analyses reflect the fact that job
classifications and work processes may differ within a given
application group. Table VIII-1 shows the application groups analyzed
in the economic analysis, and the numbers of MC-using establishments,
MC-exposed workers, and estimated volume of MC handled annually by
establishments in each application group.

Footnote(*) In most cases, the estimated number of establishments in
each application group was based on the volume flow of MC in 1990
divided by the estimated MC use per facility. The estimated number of
establishments was multiplied by the total number of employees per
establishment and exposed employees per establishment as reported in
CONSAD's survey.
Footnote(**) Netting out rehandling, estimated total consumption
equals 469.2 million pounds manufactured, minus 129.1 million pounds
exported, + 19.3 million pounds imported, + 32.10 million pounds
recovered from used solvent. The column does not sum to 391.5 million
pounds because non-consumptive uses such as production, distribution
and formulation, and solvent recovery are included.
