GENERAL DISCUSSION ITEMSStandard vs. Code
Legislative Process ChangesLevels vs. Categories
Occupancy-Based vs. Risk-BasedCategory 3 Systems
Category 3 systems (previously Level 3 systems) has gone through a total rewrite. I encourage you to review.
DEFINITIONSGeneral Anesthesia & Levels of SedationDefinition ChangeImportant for determination of Anesthetizing Locations
APPLICABILITY OF THE CODEExisting Systems Clause
188.8.131.52 Still exists for existing systems not in compliance with the 2012 edition of NFPA 99. Unless it is determined that the condition poses a distinct hazard to life.Examples
1.) Zone valve without a pressure gauge2.) No Master Alarm Warning System
APPLICABILITY OF THE CODEAdded Sections 184.108.40.206 220.127.116.11
Defines which sections of the code apply to:1.) New Facilities2.) Existing Facilities3.) Both New and Existing Facilities
CENTRAL SUPPLY SYSTEM LOCATIONSCylinder Storage Temperature
Minimum temperature for N2O and CO2 Cylinders is now -29C (-20F) or per the manufacturers recommendationsBulk Systems (Over 20,000 cu. ft.)
- NFPA 55 for Oxygen SystemsCGA P-18 for Inert Gas SystemsCGA G-8.1 for Nitrous Oxide SystemsCGA G-6.1 or G-6.5 for CO2 Systems
DESIGN AND CONSTRUCTIONOutdoor Locations (18.104.22.168.2 (3))
Minimum of 2 entry /exit doors.
DESIGN AND CONSTRUCTIONElectrical Devices
Must be protected from physical damage. If at or above 5 feet AFF, then OK. If not, can be protected from physical damage.Ventilation Requirements
This section has moved to Chapter 9.3.7.
CYLINDER STORAGE22.214.171.124.4.2 has been clarified
The only time cylinders are allowed to be stored in a room with motor driven equipment is for an instrument air standby header if and only if this is the only equipment in the room. It is prohibited to store cylinder in any other location with motorized equipment.
CENTRAL SUPPLY SYSTEM LOCATIONSRemote Control Equipment (i.e. Regulators, valves, and gauges) for Central Supply Systems
Control Equipment is allowed to be remote from the source equipment with this new provision (126.96.36.199).
REMOTE CONTROL EQUIPMENT
LOCATIONS FOR MEDICAL GASES188.8.131.52.2 has been clarified
Medical gases are only allowed in areas where they will be used under the direction of a licensed medical professional for the following purposes.Direct respiration by patientsClinical application of the gas to a patient.Medical device applications directly related to respirationPower for medical devices used directly on patientsCalibration of medical devices intended for (1) through (4) above
CENTRAL SUPPLY SYSTEMSFinal Line Regulators
Now allowed to be constructed of any materials deemed suitable by the manufacturer (184.108.40.206.5.1 (6))Three-Header Manifolds
This section has been deleted from the text. This was a rarely used system configuration. Still allowed under the code, but does not have a dedicated section anymore.
CENTRAL SUPPLY SYSTEMSBulk Cryogenic Liquid Systems
Most of this section has been moved to NFPA 55: Compressed Gases and Cryogenic Fluids Code. Some requirements still remain in NFPA 99 mostly dealing with system cascading operations, clearances for maintenance, alarm requirements, and the EOSC & In-Building Reserve requirements.
CENTRAL SUPPLY SYSTEMSIn-Building Reserve Headers
Reinforced wording for sizing of these headers (220.127.116.11.14). They must now be sized with consideration of the following:
) The minimum allowed cylinders or containers.2.) The ability of the supplier to restock the facility.3.) Access to alternative supplies / suppliers.4.) The facilities plan and ability to cope with an emergency outage.
MEDICAL AIR SYSTEMSParticulates Allowed
Changed from 5 mg / m3 to 1 mg / m3.Hydrocarbon Indicator
The requirement for a this pigment indicator has been removed.Liquid Ring Compressors
- Must have seal water that is treated.Must be provided with cylinder backup.
LIQUID RING SYSTEM
MEDICAL AIR SYSTEMSMedical Air Intake Location
The requirements for locations have now been aligned with the AIA / FGI Guidelines (18.104.22.168.3.12). Now intakes must be 25 ft. from any exhaust or vent and 25 ft. from areas where noxious fumes may collect.Medical Air Intake Material
Now can be made with any material allowed for vacuum pipelines.
MEDICAL AIR INTAKE LOCATION
MEDICAL AIR SYSTEMSMedical Air Dew Point
This has been corrected (FINALLY).New Medical Air Source System
Medical air proportioning systems or Blenders are now allowed (22.214.171.124.3.15). These systems create synthetic air using Oxygen USP and Nitrogen NF systems to create medical air that meets the requirements of USP. The requirements for redundancy, system monitoring, automatic switching, alarms, etc. have also been added.
MEDICAL VACUUM SYSTEMSVacuum Exhaust Materials
Piping Material can be anything appropriate for the service as determined by the manufacturer (126.96.36.199.1.2 (6)).Vacuum Exhaust Location
Exhaust locations must now discharge away from areas of public assembly (188.8.131.52.7.2 (2)).
