The document discusses two occupational health and safety management system standards: OHSAS 18001 and ANSI Z-10. OHSAS 18001 is an internationally recognized specification that provides requirements for an occupational health and safety management system. ANSI Z-10 is a US national standard currently under development. Both standards require organizations to identify hazards, assess risks, implement controls, monitor performance, and conduct management reviews to continually improve health and safety. While there are some differences in structure and development process, the requirements of the two standards are largely compatible.
