NFPA 99: Health Care Facilities Code, Chapter 10, is the technical standard that governs PCREE testing at skilled nursing facilities. CMS and state surveyors cite Chapter 10 directly when issuing PCREE deficiency citations. This guide translates the standard's requirements into practical terms for SNF administrators.

NFPA 99: Health Care Facilities Code is the National Fire Protection Association's comprehensive standard for healthcare facility safety, covering electrical systems, medical gas systems, and related infrastructure. It is published and updated by NFPA and adopted by CMS as the applicable standard for skilled nursing facilities under the Conditions of Participation at 42 CFR 483.70(a). The most current edition adopted by CMS governs SNF compliance — facilities should verify which edition their state survey agency references.
Chapter 10 is the section of NFPA 99 that specifically addresses Patient Care Related Electrical Equipment (PCREE). It establishes the technical requirements for electrical safety testing of devices used in direct patient care. The key provisions include:
Chapter 10 applies to electrically powered equipment used for patient care in healthcare facilities, including skilled nursing facilities. Equipment is categorized based on the risk classification of the space in which it is used.
NFPA 99 classifies patient care spaces by the risk of patient harm from electrical power interruption or failure:
Most skilled nursing facilities primarily operate in Category 2 spaces, but any Category 1 spaces (e.g., a skilled care unit with ventilator-dependent residents) carry the more stringent requirements.
Chapter 10 specifies the electrical safety measurements that must be performed and the acceptable limits:
| Test Parameter | Cat. 1 Limit | Cat. 2 Limit |
|---|---|---|
| Chassis leakage current (to ground) | 100 µA | 500 µA |
| Patient lead leakage (individual lead) | 10 µA | 50 µA |
| Patient lead leakage (all leads combined) | 50 µA | 500 µA |
| Ground resistance (safety ground path) | < 0.1 Ω | < 0.5 Ω |
Chapter 10 requires testing at intervals not exceeding 12 months for covered equipment. Additional testing is required before first patient use of new equipment, and after electrical repairs before returning equipment to service.
Testing must be performed by qualified personnel using properly calibrated test equipment. Test equipment (electrical safety analyzers) must have current NIST-traceable calibration certificates. The calibration documentation must be available for review alongside inspection records.
Chapter 10 requires that records of equipment testing be maintained. Surveyors interpret "maintained" to mean organized, complete, and immediately retrievable. Each record must document the device tested, test parameters measured, results, and the identity of the person who performed testing.
When CMS or state survey agency surveyors identify PCREE compliance deficiencies, they cite them under the Life Safety Code F-tag system, referencing NFPA 99 Chapter 10 as the applicable standard. The citation language typically references the specific section of Chapter 10 that was not met. Understanding Chapter 10 directly helps SNF administrators identify the specific gap cited and develop an effective Plan of Correction.
