1 Training presentation for: 2015 Florida AHCA Conference NFPA 110 Updates for 2016 David Stymiest, CHFM, CHSP, FASHE, (PE in LA MS MA) cell Copyright 2015, Smith Seckman Reid, Inc.; All rights reserved Learning Objectives Discuss NFPA clarifications that may help with current compliance activities List NFPA changes that may take effect as soon as a newer edition is adopted by any AHJ Discuss how future EPSS availability and reliability may be improved by the NFPA changes NFPA Disclaimer Although the speaker is Chairman of the NFPA Technical Committee on Emergency Power Supplies, which is responsible for NFPA 110 and 111, the views and opinions expressed in this presentation are purely those of the speaker and shall not be considered the official position of NFPA or any of its Technical Committees and shall not be considered to be, nor be relied upon as, a Formal Interpretation. Readers are encouraged to refer to the entire texts of all referenced documents. 1

2 NFPA 110 major changes Battery definitions clarified Records management section added Acceptance testing of paralleling gear controls O&M for paralleling gear controls ATS testing changes with clarifications Automatically actuated valves not permitted in fuel oil supply & return lines Clarified a few more fuzzy areas Battery definition info moved to Annex Some Changes in NFPA 110: 1999 to 2016 Batteries Lightning protection system Distribution (Ref. by 2000 LSC) Nickel-cadmium or lead acid Adequately protected Applicable reqmts; some details (Ref. by 2012 LSC) Nickel-cadmium or lead acid; differentiates VRLA vs. vented (flooded) Use NFPA 780 where LPS is required Added NFPA 99 reference 2013 Ed.; + moves some wording to Annex 2

3 Annex A.4.4.3: clarification for portable eq. Existing language states All equipment shall be permanently installed. The new Annex language clarifies the intent: to permit portable or alternate equipment whenever the permanent EPSS equipment is out of service. Some changes in NFPA 110: 1999 to 2016 Provide portable when genset out of service Transfer switch listed for emergency service (Ref. by 2000 LSC) Give consideration Yes, where available (Ref. by 2012 LSC) 2013 Ed.; Give consideration when 10 sec cannot be met A clarification: portable allowed for this case, except MV CP or mechanical (not LS/CB or emerloads) may be electrically interlocked MV breakers Features to guarantee required fuel amount addresses PI concern about sufficient controls to guarantee that the required quantity of fuel is always available with multi-use tanks is editorial because the table lists Class (hours), not Qty. 3

4 Clarify battery charger intent In addition to the prime mover-(engine-) driven charger required in , a battery charger(s), as required in Table , shall be supplied for maintaining a charge on both the starting and control battery unit. Corrects PI concern with previous double or wording. Ensures both starting and control batteries are maintained with a proper charge. Permit voltage adjustment options Addresses PI concern about existing wording that required older rheostat technology with potentially higher failure rates. Permits modern voltage adjustment technologies by replacing the older term rheostat with the more general term feature. Annex A clarifies closed transition The new Annex paragraph clarifies the intent that the intended use of closed-transition ATS or soft-loading capabilities should be permitted with utility and AHJ approval. 4

5 Adds Annex reference to NFPA 56 Adds a new Annex discussion on cleaning & purging of flammable gas systems per a request of the NFPA 56 Technical Committee Excludes automatic valves from F.O. lines According to the TC statement, reliable fuel supply to the EPS is critical and should not be subject to inadvertent interruption because the EPS may be called upon to power fire pumps and other life safety equipment during a fire. Verify paralleling gear control systems Applies only to the Installation Acceptance Test for paralleling EPSs. This new requirement addresses the need to verify the functionality of EPSS paralleling gear control systems for both paralleling and load shedding. 5

6 Some Changes in NFPA 110: 1999 to 2016 Installation Acceptance Test First routine test (Ref. by 2000 LSC) Difficult to follow time sequencing Not really stipulated, could be next monthly (Ref. by 2012 LSC) Major rewrites for clarification Immediately after passing acceptance tests Types of records Written record Permanent record 2013 Ed.; ; Also adds requirement to verify paralleling & load shed controls Installation Acceptance Test data Data that do not change are recorded at first load acceptance: (4) Cranking time (5) Time to reach operating speed (7) Time to steady state with all ATSs on EP Data that may vary are recorded at first load acceptance and also periodically: (8) Voltage, frequency, amperes (9) Engine oil pressure & water temperature Some Changes in NFPA 110: 1999 to 2016 (Ref. by 2000 LSC) (Ref. by 2012 LSC) 2013 Ed.; Application New installations unless AHJ states there is a distinct hazard to life + Chapter 8 applies to new and existing systems 1.3 Application. This document applies to new installations of EPSSs, except that the requirements of Chapter 8 shall apply to new and existing systems. Existing systems shall not be required to be modified to conform, except where the authority having jurisdiction determines that nonconformity presents a distinct hazard to life. 6

7 8.3.5(5) requires paralleling gear control ITM New Annex paragraph: A Paralleling switchgear offers many advantages when testing and exercising. The system exercise period would be initiated by the automatic transfer switch (ATS) controls, and once operating, the system could be staged to establish appropriate loading of each EPS. In addition, load-add, load-shed, load demand control, load optimization, and other operating and control features should be tested at appropriate intervals. Logic controls that contain load block information should be adjusted as necessary, and load priorities should be reviewed as ATS loads change. Some changes in NFPA 110: 1999 to 2016 Stipulated paralleling gear maintenance Stipulated battery maintenance (Ref. by 2000 LSC) None stated. All EPSS per manufacturer. Weekly inspections; follow manufacturer s specs (Ref. by 2012 LSC) Similar to ATS stipulated maintenance Also permits battery conductance testing in lieu of specific gravity 2013 Ed.; +NFPA 70B; & also adds verifying controls operate as required. New Annex language, but also references NFPA 70B for info Rotate starting ATS for monthly tests Systematically verifying during ongoing monthly testing that the start function (ATS to EPS including wiring) is still functional not previously addressed in 110 For additional guidance from speaker, also refer to: 7

8 Some changes in NFPA 110: 1999 to 2016 Loading percentages and testing time frames Testing after repairs Rotating starting ATS for monthly tests (Ref. by 2000 LSC) Absolute units (25%, 30%, 50%; 30 minutes, etc.) Required NOT required (Ref. by 2012 LSC) Not less than (NLT) clarification language added throughout Required; detailed instructions included, transfer all ATS s for NLT30 minutes NOT required 2013 Ed.; Required in Annex gives guidance when >12 Relaxes monthly ATS transfer timing TC statement: The annex material has been added to clarify that it is not required to keep every ATS in the emergency position for 30 minutes. In certain circumstances, an ATS may be electrically operated at a different time than the monthly test. New records management section TC Statement: The new section was created to consolidate record management and define record retentionrequirements. The use of the word permanent was removed to reflect actual operating conditions and to require that the facility management or AHJ define the length of record retention. Operation and test were merged to align with the requirements of the section. 8

9 New Figure B.1(e) Typical 911 Call Center TC STATEMENT: The new figure for a typical 911 call in center illustrates objectives of NFPA 110 and of Article 708 in the NEC. ITM requirements for entire EPSS From NFPA : 6-1.1* The routine maintenance and operational testing program shall be based on the manufacturer s recommendations, instruction manuals, and the minimum requirements of this chapter and the authority having jurisdiction. From NFPA : The routine maintenance and operational testing program shall be based on all of the following: (1) Manufacturer s recommendations (2) Instruction manuals (3) Minimum requirements of this chapter (4) The authority having jurisdiction NFPA 110 EPSS Emergency Power Supply System (EPSS). A complete functioning system of an EPS coupled to a system that can consist of conductors, disconnecting means, and overcurrent protective devices, transfer switches, and all control, supervisory, and support devices up to and including the load terminals of the transfer equipmentneeded for the system to operate as a safe and reliable source of electric power. 9

10 Weekly inspections From NFPA : 6-4.1* Level 1 and Level 2 EPSSs, including all appurtenant components, shall be inspected weekly and shall be exercised under load at least monthly. From NFPA : 8.4.1* EPSSs, including all appurtenant components, shall be inspected weekly and exercised under load at least monthly. From NFPA : Weekly inspections 1 (Taken from ASHE 2014 Management Monograph entitled: Managing Hospital Emergency Power Systems: Testing, Operation, Maintenance, Vulnerability Mitigation, and Power Failure Planning) Not just a generator inspection All appurtenant components include the generators and all of their auxiliary subsystems, including cooling, exhaust, fuel oil, starting, controls, and alarms (including remote alarm panels); transfer switches; and all distribution components between those points. The EPSS does not extend downstream beyond the load terminals of the transfer switch Weekly inspections 2 What should be included in a weekly inspection of a transfer switch room or an emergency distribution panel room? In the absence of any guidance from standards, AHJs, or manufacturers, consider the following questions as you walk into the room: What do you see?look at pilot lights, panels, meters, combustible storage, evidence of water ingress from above, below, or nearby rooms. Also look at adjacent rooms. Is there a problem that might affect the EPSS equipment if things aren t taken care of? What do you smell?electrical equipment sometimes warns us of upcoming faults (short circuits) with a distinctive odor, such as a burning smell or any other unusual odor. What do you hear?electrical equipment sometimes warns us of loose components by changing or amplifying its usual sounds. 10
