The best way to avoid this kind of confusion (what kind of confusion? The confusion that results from ambiguous pronouns), is to read your copy carefully checking that you can identify the noun that belongs to the pronoun.
If more than one noun emerges as a possibility, replace the pronoun with its intended noun.
