Public Input 14
Public Input No. 300-NFPA 99-2015 [ New Section after 3.3.21 ] 3.3.21 Capture Device (Plume). The hose, tube, funnel or other accessory that provides the inlet to the plume evacuation system at the site of plume generation. Statement of Problem and Substantiation for Public Input The term (used in 9.3.8) is not defined. Submitter Information Verification Submitter Full Name: MARK ALLEN Organization: BEACON MEDAES Street Address: City: State: Zip: Submittal Date: Wed Jul 01 12:53:25 EDT 2015 1 of 1 7/8/2015 11:37 AM 15
Public Input No. 301-NFPA 99-2015 [ New Section after 3.3.135 ] 3.3.134 Plume. The noxious airborne contaminants generated as by-products of certain surgical, diagnostic, and therapeutic techniques. Plume is commonly associated with procedures that include the cutting, ablation, cauterization, or mechanical manipulation of target tissue by energy-based devices such as lasers, electrosurgical generators, broadband light sources, ultrasonic instruments, etc. or mechanical surgical tools such as bone saws, high speed drills and reamers. Statement of Problem and Substantiation for Public Input Term is used (9.3.4) but not defined. This definition follows the ISO version.

National Fire Protection Association Report http://submittals.nfpa.org/terraviewweb/contentfetcher?xsl-renderas... 1 of 3 7/8/2015 10:37 AM Public Input No. 443-NFPA 99-2015 [ Section No. 9.3.6.5 ] 9.3.6.5 Indoor storage or manifold areas and storage or manifold buildings for medical gases and cryogenic fluids shall be provided with natural ventilation or mechanical exhaust ventilation in accordance with 9.3.6.5.1 through 9.3.6.8. 9.3.6.5.1 * For the purposes of this section the volume of fluid (gas and liquid) to be used in determining the ventilation requirements shall be the volume of the stored fluid when expanded to standard temperature and pressure (STP) of either the largest single vessel in the enclosed space or of the entire volume of the connected vessels that are on a common manifold in the enclosed space, whichever is larger. 9.3.6.5.2 Natural Ventilation. 9.3.6.5.2.1 Natural ventilation shall consist of two nonclosable louvered openings, each having an aggregate free opening area of at least 155 cm 2 /35 L (24 in. 2 /1000 ft 3 ) of the fluid designed to be stored in the space and in no case less than 465 cm 2 (72 in. 2 ). 9.3.6.5.2.2 One opening shall be located within 30 cm (1 ft) of the floor, and one shall be located within 30 cm (1 ft) of the ceiling. 9.3.6.5.2.3 The openings shall be located to ensure cross ventilation. 9.3.6.5.2.4 Natural ventilation openings shall be directly to the outside atmosphere without ductwork. 9.3.6.5.2.5 Mechanical ventilation shall be provided if natural ventilation requirements cannot be met. 9.3.6.5.3 Mechanical Ventilation. 9.3.6.5.3.1 Mechanical exhaust to maintain a negative pressure in the space shall be provided continuously, unless an alternative design is approved by the authority having jurisdiction. 9.3.6.5.3.2 Mechanical exhaust shall be at a rate of 1 L/sec of airflow for each 300 L (1 cfm per 5 ft 3 of fluid) designed to be stored in the space and not less than 24 L/sec (50 cfm) nor more than 235 L/sec (500 cfm). 9.3.6.5.3.3 Mechanical exhaust inlets shall be unobstructed and shall draw air from within 300 mm (1 ft) of the floor and adjacent to the cylinder or containers. 9.3.6.5.3.4 Mechanical exhaust air fans shall be supplied with electrical power from the essential electrical system. Exception: Buildings without essential electrical systems. 9.3.6.5.3.5 Dedicated exhaust systems shall not be required, provided that the system does not connect to spaces that contain combustible or flammable materials. 9.3.6.5.3.6 The exhaust duct material shall be noncombustible. 9.3.6.5.3.7 A means of make-up air shall be provided according to one of the following: (1) Air shall be permitted via noncombustible ductwork to be transferred from adjacent spaces, from outside the building, or from spaces that do not contain combustible or flammable materials. (2) Air shall be permitted to be transferred from a corridor under the door up to the greater of 24 L/sec (50 cfm) or 15 percent of the room exhaust in accordance with NFPA 90A, Standard for the Installation of Air-Conditioning and Ventilating Systems. (3) Supply air shall be permitted to be provided from any building ventilation system that does not contain flammable or combustible vapors. Statement of Problem and Substantiation for Public Input Some buildings (outpatient facilities) fall under these requirements, however do not have essential electrical systems. It is reasonable to provide them an exception so they do not have to provide emergency power for an exhaust fan. When mechanically ventilated the rooms operate at a negative pressure. Air transfer should be permitted from adjacent spaces without concern as to the amount transferred.

Public Input No. 303-NFPA 99-2015 [ Section No. 9.3.8 ] 9.3.8 Medical Plume Evacuation. Plumes from medical procedures, including the use of lasers, shall be captured by one of the following methods : in 9.3.8.1 through 9.3.8.3 below. 9.3.8.1 Direct connection to an unfiltered dedicated piped or ducted exhaust system that discharges outside the building with the following characteristics: (1) The system shall be permitted to be filtered or unfiltered and use absorbers to remove noxious materials from the air stream. (2) The system shall have dedicated producer(s) and shall not connect to HVAC, medical vacuum, WAGD or housekeeping vacuum producers. (3) Inlets shall be permitted to include automatic shutoff devices or to be open flow. (4) Flow control for the inlets shall be as appropriate for the plume capture device in use. (5) Inlets shall be permitted to be of any design suitable for the plume capture device in use, provided the design does not permit interconnection to any medical vacuum, WAGD or housekeeping vacuum systems also installed in the room. 9.3.8.2 HEPA filtering and direct connection to a return or exhaust duct. 9.3.8.3 Chemical and thermal sterilization and return to the space. 9.3.8.4 The plume evacuation system shall have either: (a) an indicator to demonstrate the system is operating within normal parameters or; (b) an alarm to indicate the system is not usable. Statement of Problem and Substantiation for Public Input The requirements in chapter 9 are an ideal starting point for defining these systems. Two standards now in place internationally take these requirements further (ISO 16571 and CSA Z305.13) defining essential safety elements that NFPA can usefully incorporate as follows: 1. some systems include not only filtration but absorbers to reduce objectionable odors. 2. Because plume is known to contain pathogens, viruses and other dangerous material, it is essential that the system not be mixed with other vacuum applications. The temptation will certainly arise as some are similar in pressure or flow, or may appear to offer "economies of scale" when combined. 3 and 4. Inlets for plume evacuation can resemble terminal outlets for medical vacuum, open tubes or inlets for housekeeping vacuum systems. However, their operation is not necessarily like any of these. Thus it makes sense to clarify that the terminal should be designed to mate with the intended capture device and to include such features as are appropriate. 5. The design freedom implied in the preceding clauses cannot be extended to inlet designs which can be inadvertently misconnected.
