For the 1993 edition of NFPA 99 there were further efforts to make the document more user-friendly (e.g., placing all “recommended” guidance either in notes or in the appendix). Significant technical changes included the follow- ing: adding requirements and recommendations to further prevent or minimize fires in operating rooms; making major changes to requirements in Chapter 4 for installing, testing, inspecting, verifying, and maintaining nonflam- mable medical piped gas systems; adding new sections on dental compressed air and dental vacuum requirements in Chapter 4; changing leakage current limits of patient care–related electrical appliances to correlate more closely with an international document on the subject; revising laboratory requirements to correlate more closely with NFPA 45, Standard for Laboratories Using Chemicals; changing essential electrical system requirements in ambulatory health care clinics and medical/dental offices; and extensively revising hyperbaric chamber requirements (Chapter 19).

For the 1996 edition of NFPA 99, further changes to make the document more user-friendly were made. These included restructuring Chapters 3 and 4 so that all requirements for a Type 1, 2, or 3 essential electrical system, or a Level 1, 2, 3, or 4 piped gas or vacuum system, were contained in one section.

Other technical changes included the following:

(1) Moving requirements on flammable anesthetizing locations and the use of flammable inhalation anesthetics to a new Appendix 2

(2) Upgrading the subject of emergency preparedness from guidance to a new chapter containing requirements (3) Adding a new chapter (Chapter 18) on home health care (4) Revising Section 1-1 to reflect the intent that NFPA 99 applies only to facilities treating human beings (5) In Chapter 3, revising load testing requirements for emergency generators to reference NFPA 110, Standard for

Emergency and Standby Power Systems, and revising emergency lighting criteria for operating rooms (6) In Chapter 4, revising requirements for medical compressed air systems, dental compressed air systems, waste

anesthetic gas disposal systems, and dental piped gas/vacuum systems; adding a new section on “headwall units” (“manufactured assemblies”); and clarifying and moving requirements for transfilling containers of liquid oxygen to Chapter 8

(7) In Chapter 8, adding requirements for storage rooms containing cylinders and containers totaling less than 3000 ft3

(8) In Chapters 12 to 17, revising criteria for gas and vacuum systems (9) In Chapter 19, in addition to many technical changes, adding criteria for mobile hyperbaric facilities

For the 1999 edition, significant technical and structural changes included the following:

(1) Chapters 13, 14, and 15 (on ambulatory health care centers, clinics, and medical/dental offices, respectively) were replaced completely by new Chapter 13 covering health care facilities other than hospitals, nursing homes, and limited care facilities as defined in Chapter 2.

(2) Requirements for Level 2 gas and vacuum systems were developed (Section 4.4 in Chapter 4). (3) Subsections 12.3.4, 16.3.4, and 7.3.4 were revised to correlate with the two significant changes in (1) and (2). (4) In Chapter 3, load testing requirements for emergency power supplies of the essential electrical system were

changed through reference, and the testing interval (“monthly”) was reworded to be more responsive to needs of health care facilities.

(5) Clarification of transfer switches and branches of the emergency system was made. (6) Clarification on the use of emergency power supplies other than for emergency power was made in 3.4.1.1.5. (7) Paragraph 4.3.1.2, Distribution Requirements for Level 1 Gas Systems, was completely revised and restructured. (8) Chapter 4 was made more user-friendly by reducing the number of internal cross-references between Sections

4.3 and 4.5. (9) The order of installation and testing requirements for piped gas and vacuum systems was revised.

(10) Emphasis on emergency preparedness was made in Chapter 11 and its appendix material. (11) Chapter 19, “Hyperbaric Facilities,” was extensively revised in the areas of electrical wiring, air quality, ventilation

lighting, equipment, communication, and safety management. (12) A new chapter (Chapter 20) on freestanding birthing centers was added.

The 2002 edition included format and technical revisions. The Manual of Style for NFPA Technical Committee Docu- ments, April 2000 edition, was applied to this document, resulting in changes to its structure and format. Introductory material in Chapter 1 was formatted for consistency among all NFPA documents. Referenced publications that apply to the document were relocated from the last chapter to Chapter 2, resulting in the renumbering of chapters. Informa- tional references remained in the last annex. Appendices were designated as annexes. Definitions in Chapter 3 were

eviewed for consistency with definitions in other NFPA documents, were systematically aligned, and were individually umbered. Paragraph structuring was revised with the intent of one mandatory requirement per section, subsection, r paragraph. Information that often accompanied many of the requirements was moved to Annex A, Explanatory aterial. Exceptions were deleted or rephrased in mandatory text, unless the exception represented an allowance or

equired alternate procedure to a general rule when limited specified conditions exist. The reformatted appearance nd structure provided continuity among NFPA documents, clarity of mandatory text, and greater ease in locating pecific mandatory text.

The document scope and individual chapter scopes defining the intent of each chapter and document as a whole ere located in Chapter 1.

The occupancy Chapters 13–21 stated what is required, while Chapters 4–12 prescribed how those requirements re achieved. Each chapter began with a section explaining applicability. Information concerning the nature of azards was moved to Annex B. Annexes A and C retained explanatory information, and Annexes 1 and 2 became nnexes D and E. Informational references were in Annex F.

The changes in Chapter 4, Electrical Systems, addressed electrical wiring, transfer switches, inspection, and appli- ation.

Chapter 5 on Piping Systems was realigned so that Level 1 requirements were found in Section 5.1, and concur- ently Level 2 in Section 5.2 and Level 3 in Section 5.3. Level 4 associated with laboratories was deleted, with require- ents realigned in Chapter 11 on laboratories. Definitions were developed for vacuum systems and Levels 1, 2, and 3

as systems in Chapter 3. Revisions were made to compressed gas cylinder identification and restraint; valve venting; entilation of storage rooms; alarms; connection of the electrical supply for central supply systems with the essential lectrical system; allowance of a three-way full port ball valve to isolate one branch or component; provisions for a onitored and audible low-content alarm on the surge gas while brazing; the allowance of medical air systems for

pplication with human respiration; and deletion of 20-year-old appendix information.

Gas Delivery, Chapter 8, included a new section on the storage of compressed gas cylinders in patient care areas.

Chapter 11, Laboratories, clarified the structural protection of exits, and intent of portable fire extinguishers. evisions were made concerning flammable and combustible liquids handling requirements.

An increased focus on the total process of maintaining services during a disaster, mitigating damage from a disaster, nd recovery from a disaster was reflected in Chapter 12, Emergency Management. Annexed security program infor- ation was expanded.

Chapter 20, Hyperbaric Facilities, contained revised emergency depressurization requirements, safety director esponsibilities, and emergency procedure performance.

The changes made to the 2005 edition were mainly for clarity and were editorial in nature. In Chapter 3, the efinitions for medical gas, patient medical gas, and medical support gas were modified to differentiate between the ifferent types of gases.

In Chapter 4, the requirements for switches and receptacles in anesthetizing locations were moved to Chapter 13, ospital Requirements. The extracted material from NFPA 110, Standard for Emergency and Standby Power Systems, was pdated.

In Chapter 5, the requirements for construction materials for filters, dryers, regulators, vacuum pumps, and after- oolers were changed to allow the manufacturers to choose the materials.

A centralized computer was allowed to be used in lieu of one of the master alarms. Cylinders were allowed to be itted with a means to slow the initial opening pressure. The requirement to individually secure the cylinders was hanged to no longer require the cylinders to be secured individually. Two new methods for making joints were added o the requirements. Stainless steel tubing was added as an approved material for vacuum systems. The requirement to raze a joint within 1 hour after cleaning was changed to 8 hours. Vacuum joints were required to be leak tested, and perational pressure testing was permitted to be conducted with the source gas.

Chapters 6, 7, 8, 9, 10, and 11 underwent minor changes for clarity or for editorial reasons.

Chapter 12 was revised to update the techniques used in emergency management in health care facilities.

In Chapters 13, 14, 15, 16, 17, 18, and 19 editorial corrections were made.

Chapter 20 was revised to include requirements for heating and ventilation changes in the chamber. Additional estrictions to the types of materials that are allowed in the chamber were added.

The 2012 edition went through a major overhaul. The premise of an occupancy-based document was modified to ecome a risk-based document. NFPA 99 was changed to a “code” instead of a “standard” to reflect how the document

s used and adopted.

The administration of health care continues to change. NFPA 99 has changed to reflect how health care is deliv- red. The risk to the patient does not change for a given procedure. If the procedure is performed in a doctor’s office ersus a hospital, the risk remains the same. Therefore, NFPA 99 eliminated the occupancy chapters and has gone to a isk-based approach. New Chapter 4 outlines the parameters for this approach. The Code now reflects the risk to the atient in defined categories of risk.

Chapter 5, Gas and Vacuum Systems, went through some editorial changes as well as adding new material on the testing and maintenance of gas and vacuum systems. In addition, the administrative details for care, maintenance, and handling of cylinders moved to chapters under the responsibility of the new Technical Committee on Medical Equipment.

There are several new chapters. There are new chapters on Information Technology and Communications Systems for Health Care Facilities; Plumbing; Heating, Ventilation, and Air Conditioning; Security Management; and Features of Fire Protection. Many of these systems were not addressed by NFPA 99. These are important systems and protection features in health care and needed to be addressed. The Technical Committees on Gas Delivery Equipment and the Technical Committee on Electrical Equipment were combined into a single Technical Committee on Medical Equip- ment. The hyperbaric chapter had relatively minor changes for clarity.
