29 CFR 1910.132

Does OSHA require an annual PPE hazard assessment?

No. Federal OSHA's 29 CFR 1910.132(d) requires a workplace hazard assessment and a written certification of it, and it sets no interval for doing either again. The only federal text about reassessing is nonmandatory Appendix B, which says “as necessary.” The yearly clocks in federal PPE rules belong to respirators under 1910.134, the fit test and retraining, and to the tests of rubber insulating equipment in construction.
