Question

fairfax assembly paint booth cleaning
at gms fairfax assembly plant, paint booths were originally cleaned every other day (after production) to prevent stray drops or chips of old paint from attaching to subsequent paint jobs. it was discovered, however, that the automated section of the painting operations really only needed to be cleaned once a week, as long as the cleaning was thorough, and larger holes were cut in the floor grating to allow for thicker paint accumulations. the reduction in cleaning frequency facilitates improvements in the process \up - time\ and flow. as an additional benefit, through this and other more efficient cleaning techniques, use of purge solvent decreased by 3/8 of a gallon per vehicle. when combined with reductions achieved by solvent recycling, voc emissions from purge solvent reduced by 369 tons in the first year following these adjustments.
○ the primary goal of lean manufacturing is to reduce pollution.
○ environmentally friendly solvents are the only way to reduce emissions.
○ using fewer chemicals reduces pollution as well as improves efficiencies in manufacturing.
○ environmental concerns typically increase the costs of sustainable manufacturing.

Explanation:

The text describes reducing cleaning frequency (which can be related to using fewer resources like solvents) leading to improved process "up - time" (efficiency) and reduced VOC emissions (pollution reduction).

• The first option is incorrect as the text shows multiple benefits (efficiency and pollution reduction) not just pollution reduction as the primary goal.
• The second option is wrong because the text uses methods like reducing cleaning frequency and solvent recycling, not just environmentally friendly solvents.
• The fourth option is incorrect as the text shows a positive outcome (reduced emissions and improved efficiency) rather than increased costs.

Answer:

Using fewer chemicals reduces pollution as well as improves efficiencies in manufacturing.
