Yes you can. As soon as your care outweighs the benefit, you're too careful.
Do you wear a helmet when driving to work? Have a roll cage in the car? Home sprinkler fire suppression system automatically triggered by heat or smoke? Do you wear a class IIIA ballistic vest with chest and back hard plates while shooting (in case someone accidentally lights one off in your direction)? Why not? Because the cost outweighs the savings.
Pullers are demonstrated to be perfectly safe. Wear your eyes just in case, and don't put any part of your body directly above the round, and bang away.
