Standards: what's new in NFPA 99-1993?

Another revision cycle for the National Fire Protection Association's (NFPA) Standard for Health Care Facilities (ANSI/NFPA 99, An American National Standard, February 12, 1993) was recently completed. The 1993 edition incorporates numerous changes. Below, we present a summary of the changes that relate to electrical systems and electrical safety. Extensive changes have also been made to the chapters dealing with medical gas systems; we will be commenting on these revisions in an upcoming Health Devices article on medical gas systems, and we will discuss other changes in future issues as the need arises.
