This regulation specifies electrical system requirements for patient care rooms in healthcare facilities, categorizing rooms by risk level (Category 1 critical care, Category 2 general care, Category 3 basic care) and mandating corresponding Essential Electrical System (EES) types. Facilities must ensure critical care rooms with life support equipment are served by a Type 1 EES, general care rooms by Type 1 or Type 2 EES, and that Type 3 EES life safety branches provide at least 1.5 hours of alternate power. This is a CMS Life Safety Code survey tag (Form CMS-2786R) governing physical plant electrical infrastructure standards.

Type 3 EES life safety branch has an alternate source of power that will be effective for 1 1/2 hours. 3.3.138, 6.3.2.2.10, 6.6.2.2.2, 6.6.3.1.1 (NFPA 99), TIA 12-3 Form CMS-2786R (07/2018) Page 41 Name of Facility 2012 LIFE SAFETY CODE ID PREFIX MET NOT MET N/A REMARKS
