FED 8-4-1g Interpretation

[greymule]

The runner can interfere with a throw or he can interfere with the fielder "fielding" a throw. Nothing to do with a batted ball.

I don't do Fed, but reading the quoted rule in the OP led me to believe that a batted ball was included, which seemed illogical. If indeed the rule has nothing to do with a batted ball, then "while the ball is being fielded or thrown to first base" is poor wording. Since a ball isn't "fielded to 1B," the phrase "fielded" stands completely separate from "thrown to 1B." Maybe "while a throw to 1B is being made or received" would be better.
