ANSI/ASSP Z10 is a voluntary standard that provides a Plan-Do-Check-Act framework for building an occupational health and safety management system.

A voluntary American National Standard, published by ASSP, that defines the core elements of an occupational health and safety management system (OHSMS). Built on the Plan-Do-Check-Act cycle, it covers management leadership, employee participation, hazard identification and risk assessment, implementation of controls, evaluation, and continual improvement.
A mid-sized distribution company uses ANSI Z10 as a roadmap to move from a compliance-only safety program to a structured management system, setting annual objectives, auditing its controls, and reviewing results with senior leadership each quarter.
Both standards describe an OHS management system using a Plan-Do-Check-Act structure, and the current edition of Z10 was designed to be compatible with ISO 45001, so organizations can use either as a framework or move between them.
Z10 is primarily used as a voluntary framework for building and improving a management system; organizations seeking third-party certification more commonly pursue ISO 45001.
No, Z10 provides a management framework that sits on top of legal requirements; organizations still must comply with all applicable OSHA and other regulatory standards.
