Attachment D: NFPA 45 Public Input Report Page 13 of 75

Public Input No. 48-NFPA 45-2017 [ Section No. 1.1.2 ] 1.1.2 This standard shall apply to all educational laboratory units and instructional laboratory units in which any quantity of chemicals, as defined in NFPA 704 with one or more of the following hazard ratings, is handled or stored: health 2, 3, or 4: flammability 2, 3, 4; or instability 2, 3, 4. (See also Section B.2). Additional Proposed Changes File Name Description Approved NFPA_45_TIA_15-1_Log_1150.pdf NFPA 45 TIA 15-1 LOG 1150 NOTE: This public input originates from Tentative Interim Amendment No. 15-1 Log 1150 issued by the Standards Council on November 11, 2014 and per the NFPA Regs., needs to be reconsidered by the Technical Committee for the next edition of the document. Submitter s Substantiation: During the 2nd draft meeting for the current revision cycle of NFPA 45, the technical committee deleted the definition of chemical in chapter 3 and moved the wording to paragraph 1.1.1 where the document used to have the wording of in which chemicals, as defined, are handled or stored. This was in response to a public comment on the definition in Chapter 3. During the 1st draft meeting, the technical committee made a first revision to the document adding paragraph 1.1.2 to apply NFPA 45 to all educational and instructional laboratories. The second draft of the 2015 edition reads as follows:1.1.1* This standard shall apply to laboratory buildings, laboratory units, and laboratory work areas whether located above or below grade in which chemicals, as defined, in NFPA 704 with one or more of the following hazard ratings are handled or stored: health 2, 3, or 4; flammability 2, 3, or 4; or instability 2, 3, or 4. (See also Section B.2.). 1.1.2 This standard shall apply to all educational laboratory units and instructional laboratory units in which any quantity of chemicals, as defined, is handled or stored. The bold portion of 1.1.2 is the problem. Since the technical committee deleted the definition of chemical from Chapter 3, this statement is not accurate. I am therefore requesting that analogous language be added to 1.1.2 in order to adequately define the scope of the document. The new wording for 1.1.2 will be similar to 1.1.1 as proposed above. Emergency Nature: This document, if issued as final without the proposed change, will contain an error or an omission that was overlooked during a regular revision process. Neglecting to modify 1.1.2 to match the terminology in 1.1.1 was an oversight by the Technical Committee.

Public Input No. 50-NFPA 45-2017 [ Section No. 1.2.5 ] 1.2.5 It is not the objective of this standard to address financial losses such as business interruption or property loss when the loss of a laboratory unit is unacceptable. We believe that the use of the term unacceptable in 1.2.5 does not provide clarity or added context to the statement as written and may confuse users of the standard. We note that the NFPA glossary of terms contain no formal definition of unacceptable. The only other appearance of the word unacceptable is in 1.4.2, where the term seems appropriate and is understandable to the reader.

Public Input No. 46-NFPA 45-2017 [ Section No. 1.3.3 ] 1.3.3 Due to the special nature of laboratories using chemicals, this standard modifies and supplements existing codes and standards so as to apply more specifically to buildings or portions of buildings devoted to laboratory-scale operations. Additional Proposed Changes File Name Description Approved NFPA_45_-_PC_13.pdf NFPA 45 PC 13 NOTE: This Public Input appeared as "Reject but Hold" in Public Comment No. 13 of the F2014 Second Draft Report for NFPA 45 and per the Regs. at 4.4.8.3.1. We are in agreement with the technical committee that the proposed new section is not needed and that AHJ can determine the applicability of codes and standards. We recommend consideration be given to study the need to convert NFPA 45 from a standard to a code for laboratories. As Section 1.3.3 states, this standard modifies and supplements existing codes and standards so as to apply more specifically to buildings or portions of buildings devoted to laboratory-scale operations. The criteria in this standard establishes and excellent benchmark for safety in laboratory-scale operations which differ considerably from building codes in that it specifies laboratory units based upon a density method and maximum quantity per laboratory unit as opposed to the control area method that building codes utilize based only upon maximum quantity. The building codes have unrealistic restrictions on the amount of chemicals that can be stored at higher floors whereas NFPA 45 reduces this restriction but adds the requirement for automatic sprinkler systems for new laboratories, sealing floor penetrations liquid tight, and other safety requirements. With research facilities at Colleges and Universities growing, NFPA 45 provides a more realistic and stable approach to support this growth. Applying NFPA 45 as a standard in conjunction with existing building codes presents too many conflicts to apply in a reasonable fashion to new construction and/or renovations to existing structures. Applying existing building codes to existing buildings, many built prior to the control area concept, severely limits the use and upgrade of existing laboratory buildings. NFPA 45, with the density method, would allow better use of buildings, especially multi-story buildings, where the owner agrees to limit the density to NFPA 45 requirements. A code is needed to specifically address laboratory-scale operations and facilities.

Submitter Full Name: Bill Galloway Organization: Southern Regional Fire Code De Submittal Date: Tue Oct 29 14:59:14 EDT 2013 Committee Statement Committee Action: Resolution: Rejected but held As this would be a major change, the technical committee feels that it needs time to investigate and address the impact of changing from a standard to a code. The committee feels that this would be best addressed as part of the next revision cycle and is holding this comment for public input. The committee will be setting up a task group to address the implication of this possible change. of 2 Page 18 of 75 1/4/2017 1:15 PM

Public Input No. 55-NFPA 45-2017 [ New Section after 3.3.39 ] TITLE OF NEW CONTENT Type your content here... 3.3.38 Laboratory User Persons who occupy a Laboratory Work Area to conduct work, testing, analysis, research, instruction, teaching or to engage in learning, or similar activities that involve the use of chemicals. Presently no definition exists for "Laboratory User." This change is proposed to support an additional change I have proposed in wording to 6.5.3.3. The wording of 6.5.3.3 currently places an emphasis on students and instructors and implies that training and emergency planning under the standard applies only to laboratories used for instructional purposes (e.g., chemistry classrooms for K-12 or Post-secondary education or similar). This proposed definition aligns with 3.3.39, definition for Laboratory Work Area and borrows wording from this same definition. Adding this definition and adopting proposed changes to 6.5.3.3 will support understanding that 6.5.3.3 also applies to laboratory settings that are non instructional in nature (i.e., research laboratories, etc.) Submitter Full Name: John Bernhards Organization: APPA Submittal Date: Thu Jan 05 16:36:14 EST 2017 Page 28 of 75 2 of 58 1/17/2017 11:11 AM

NFPA 101 references NFPA 45 and NFPA 30. Hospital Laboratories are to be built to NFPA 45 in accordance with NFPA 101 Chapter 18. There seems to be conflicts since NFPA 30 is referenced by NFPA 45, but NFPA 30 would not allow storage of Class I flammable liquids in basements. Personally, I don't think it is a good idea to permit Class I flammable liquids to be stored in basements of healthcare occupancies where patients are unable to evacuate the building, even with the safeguards that are in place. However, it appears that NFPA 45 intends to allow Class I flammable liquids to be stored in basements per Table 5.1.1. The conflict should be addressed so that users of NFPA 101, NFPA 45, and NFPA 30 understand what is expected. Presently, NFPA 101, which references NFPA 30, would not permit the storage of Class I flammable liquids in basements, but Table 5.1.1 of NFPA 45 appears to permit it. Do you want to be lying in a hospital bed with 800 gallons of flammable liquids (per Lab unit) in the basement that can't be easily accessed by the fire department? Even if this proposal is not accepted, the conflict between NFPA 45 and NFPA 30 for storing Class I flammable liquids in basements needs to be addressed.

Public Input No. 9-NFPA 45-2016 [ Section No. 5.1.5 ] 5.1.5 Floors, floor openings, floor penetrations, and floor firestop systems shall be sealed to prevent liquid leakage to lower floors. The sealing material shall be compatible with the chemicals being stored or used in the laboratory. Curbing may be used to prevent leakage and meet chemical compatability but, if used, must be sealed in accordance with all local fire and building codes. Curbing with openings inside the curb (the usual installation) was removed as an option to meet fire and building code requirements. However, fire stop sealants often have limited chemical compatibility so allowing sealed curbing is often a better approach. The curbing prevents leakage and keeps the sealant from being exposed to the chemicals.

Public Input No. 54-NFPA 45-2017 [ Section No. 6.5.3.3 ] 6.5.3.3 All laboratory users, including, but not limited to, instructors and students, shall be trained prior to laboratory use and at least annually thereafter on the emergency plan. While 6.5.3.3 references all laboratory users, including but not limited to...", the wording of this section places an emphasis on students and instructors and implies that training and emergency planning under the standard apply only to laboratories used for instructional purposes only (e.g., chemistry classrooms for K-12 or Post-secondary education or similar). A better solution is to formalize the term Laboratory User by adding a definition that aligns with 3.3.39, definition for Laboratory Work Area. If the current wording of this section was to emphasize safety training in campus/school laboratories, it should be noted that many post secondary institutions operate substantial research facilities that include public-private research partnerships and other models that support critical research facilities and that are not necessarily designed for classroom instruction. Use of a definition for "Laboratory User" that is in alignment with 3.3.39 supports broadened relevance of safety training and emergency preparedness to a wider variety of laboratory settings and work areas. To support this proposed change to 6.5.3.3, also please see new proposed definition for Chapter 3 which reads " Laboratory User Persons who occupy a Laboratory Work Area to conduct work, testing, analysis, research, instruction, teaching or to engage in learning, or similar activities that involve the use of chemicals."

Public Input No. 53-NFPA 45-2017 [ Section No. 7.2.2.1 ] 7.2.2.1 If laboratory exhaust ventilation is out of service or inoperable, all laboratory operations shall be suspended until the deficiency is corrected. All hazardous materials shall be secured in a safe condition or removed from the laboratory during the time that the deficiency exists. New construction with fume hoods should be connected to emergency or stand-by power to insure continued operation in an electrical failure. Existing buildings should be grandfathered. NFPA does not require fume hoods to be connected to emergency or stand-by power to insure continued operation in an electrical failure. It asks that in the event of a power failure all experiments and operations be suspended, materials secured, lab evacuated until declared safe. This does not recognize that some fumes can become toxic/lethal within seconds of loss of containment, not providing enough time to secure and evacuate. Furthermore, some experiments run continuously with little attendance by someone who react to a power failure. Furthermore, a power failure could go unnoticed as these events are generally not alarmed, or the failure could be local and notice is not provided to either the area of failure nor to adjacent areas where normal operation is in process. Providing back-up power to fume hoods also must be factored into design air flow pressures, door swings, latching etc. as full capacity can create situations where the suction against the pull side of a door is enough to inhibit being able to open it.

Public Input No. 45-NFPA 45-2017 [ Section No. 7.3.1 ] 7.3.1 Laboratory ventilation systems shall be designed to ensure that chemical fumes, vapors, or gases originating from the laboratory shall not be recirculated to other spaces. Similar to the A7.4.1 and 7.4.1 public input I have provided, this section is occasionally misunderstood to also apply to ductless and filtered fume hoods even though it is in for supply systems. Recirculation of supply air is acceptable via chilled beams and fan coil units for localized cooling technologies. Submitter Full Name: Kenneth Crooks Organization: Erlab, Inc.

Public Input No. 44-NFPA 45-2017 [ Section No. 7.4.1 ] 7.4.1* Air exhausted from ducted chemical fume hoods and other special local exhaust systems shall not be recirculated. Air exhausted form ductless or filtered chemical fume hoods can be recirculated within the same lab space. (See also 7.3.1.) Similar to the A7.4.1 public input I have provided, the wording in this section does not allow for newer technologies that can safely filter and recirculate the clean air back into the same lab space. It is clear that contaminated (ducted) fume hood exhaust air is not to be recirculated, in the common meaning of the word as with Return Air HVAC systems. That was clearly the intent of this section when first written into the Standard and why the use of the word Discharge in the section heading. Labs are to have single-pass 100% OA systems to provide ventilation air at all times. Thus, the air must also be exhausted from the lab space(s) and, due to the potential of contamination, shall not be recirculated back into the building. None of that changes in any way when ductless or filtered chemical fume hoods are used in the lab as they do not have contaminated exhaust air that requires exhausting from the lab space or otherwise requires discharging. Rather, a ductless or filtered chemical fume hood returns directly to the same lab space cleaner air than that which entered the open sash area. Additionally, the air is not recirculated within the building; it is cleaned and then recirculated within the lab space only. Recirculation of air within the same lab space is permissible by other Standards, the requirements for doing so are detailed in the ANSI/AIHA Z9.5 2012 Standard, section 5.4.7.
