Question

all of these are true about finish removal with mecl paint stripper except
a) mecl is a red liquid with a strong, sour odor.
b) if any amount of mecl paint stripper is used, the tech must notify the epa of being a user.
c) abrading the surface prior to applying mecl may reduce the amount of mecl stripper applied.
d) placing a sheet of plastic film over the finish can reduce the overall amount of stripper that gas emitted.

Explanation:

• Option A: Methylene chloride (MeCl) is indeed a volatile liquid with a strong odor, so this is true.
• Option B: OSHA regulations do not require notifying them for any use of MeCl paint stripper; notification rules apply to specific exposure thresholds or large-scale use, not any amount. This statement is false.
• Option C: Abrading the surface breaks down the existing finish, so less stripper is needed, making this true.
• Option D: Plastic film traps vapors, slows evaporation, and reduces the amount of stripper that evaporates, so this is true.

Answer:

B) if any amount of MeCl paint stripper is used, the firm must notify the EPA of being a source
