NFPA 2001
Standard on Clean Agent Fire Extinguishing Systems
2000 Edition
Reference: Various
Errata No.: 2001-00-2 The Committee on Halon Alternative Protection Options notes the following errors in the
2000 edition of NFPA 2001, Standard on Clean Agent Fire Extinguishing Systems.
1. Add the following isometric diagrams for HFC-236fa see Figure A-2-1.4.1 (ii)
through (ll) enclosed.
2. In Table 1-6.1.2.1 (a), the % LOAEL for HFC-23 should be changed from“>5”to
“>50”.
3. In Table A-1-5.1 (a), in the tenth row with the heading Heat of Vaporization at
Boiling Point, delete “at 25°C”.
4. In Table A-1-5.1 (c) in the second Row, change the Heading from “Boiling Point
at 19.7 psia” to “Boiling Point at 14.7 psia.”
5. In Figures A-2-1.4.1 (c) through (h) change “FE-25” to “HFC-125” in the Figure
Headings.
6. In Figures a-2-1.4.1 (d), (h), and (v) change the comas to decimal points.
7. Replace Table 2-2.1.1 (a) with the enclosed new version:
8. In Table 2-2.1.1 (b) change the row for 600 psig container pressure for HFC-227ea to read as follows:

In Table A-1-5.1 (c) in the second row, change the heading from Boiling Poi19.7
9. Change paragraph 2-2.1.2 to read as follows:
2-2.1.2 Cast-iron pipe, steel pipe conforming to ASTM A 120, Specifications for Pipe,
Steel, Black, and Hot-Dipped Zinc Coated, Welded and Seamless for Ordinary Uses , ornonmetallic pipe shall not be used.
10. Delete Table A-2.2.1.1 (d)
11. In A-2.2.1.1 (e) second paragraph, change the reference from “Table A-2.2.1.1 (i)(1) and Table A-2.2.1.1 (i) (2).”to “Table 2.2.1.1(a) and Table 2.2.1.1 (b).”
12. In A-2.2.1.1 (e) last paragraph, change the second sentence to read:
“ In this case, the governing criteria of 2-2.1.1 (2) is 80 percent of the pressure in the
agent container at 160°F.”
13. In A-2.2.1.1 (h) (1) change the reference from “Table A-2.2.1.1 (i) (1)” to “Table
2-2.1.1 (a).”
14. In A-2.2.1.1 (h) (2) change the reference from “Table A-2.2.1.1 (1)(2)” to “Table
2.2.1.1 (b).”
15. In Table A-3.5.1 (e) change the headings of the columns to read as follows:
