dMaterial has been classified by test.

eWhere all conduit runs into explosionproof equipment, the conduit is provided with explosionproof seals installed within 18 in. (450 mm) of the enclosure, equipment for the group classification shown in parentheses is permitted.

fFor classification of areas involving ammonia, see ANSI/IIAR 2 Standard for Safe Design of Closed-Circuit Ammonia Refrigeration Systems, and CGA G2.1, Safety Requirements for the Storage and Handling of Anhydrous Ammonia.

gCommercial grades of aliphatic hydrocarbon solvents are mixtures of several isomers of the same chemical formula (or molecular weight). The autoignition temperatures (AIT) of the individual isomers are significantly different. The electrical equipment should be suitable for the AIT of the solvent mixture. (See A.4.4.2.)

hCertain chemicals have characteristics that need safeguards beyond those necessary for any of the above groups. Carbon disulfide is one of these chemicals because of its low autoignition temperature and the small joint clearance necessary to arrest its flame propagation.

iPetroleum naphtha is a saturated hydrocarbon mixture whose boiling range is 68°F to 275°F (20°C to 135°C). It is also known as benzine, ligroin, petroleum ether, and naphtha.

jFuel and process gas mixtures found by test not to present hazards similar to those of hydrogen can be grouped based on the test results.

k Liquid type and flash point vary due to regional blending differences.

Statement of Problem and Substantiation for Public Comment

A number of materials were incorrectly labeled as to Type, that is Gas, or liquid Class, based on the tabulated normal boiling points and flash points. Additionally multiple materials listed as having the same CAS number either do not include the same information or should not be listed as the same CAS number. Recommended changes are substantiated by screenshots from the DIPPR database, which is a recognized source of critically evaluated thermo-physical property data. A US Coast Guard document downloaded from the Cameo website supports the recommended data for mixed isodecaldehydes. Related Item • FR-3

Statement: A number of materials were incorrectly labeled as to Type, that is Gas, or liquid Class, based on the tabulated normal boiling points and flash points. Additionally multiple materials listed as having the same CAS number either did not include the same information or should not have been listed as the same CAS number. These changes are from the DIPPR database, which is a recognized source of critically evaluated thermo-physical property data. A US Coast Guard document downloaded from the Cameo website supports the recommended data for mixed isodecaldehydes. Additional MESG and MIC ratio data were extracted from ISO/IEC 80079-20-1. The MESG for Methyl Ethyl Ketone was updated based on independent test data.

10 of 15 12/10/2019, 1:59 PM Bill,

I have followed up on the materials listed below as well as multiple synonym entries where the properties do not match and offer DIPPR support for my comments to update the material data table. This is NOT a complete review of the data table, but it is significant enough that I believe we need to make updates. The Design Institute for Physical Properties (DIPPR) is the world's best source of critically evaluated thermo‐physical and environmental property data. Using a proprietary data evaluation methodology DIPPR’s recommended values allow practitioners to quickly produce results from their computational tools rather than spending time ensuring that the underlying data are robust. DIPPR data are used by leading chemical, petroleum, and pharmaceutical companies throughout the world and used extensively in third‐party software. The DIPPR process uses a systems approach in evaluating data from all available sources to triangulate on the best values, resulting in higher accuracy than could be achieved using only individual points. This approach includes hundreds of applied constraints on property values stemming from inter‐ property relationships, expected trends of properties between related chemicals, and the impact of chemical similarities and differences. Once these constraints are simultaneously satisfied for all properties, experts review the compound and give final approval for the compound to be added to the database. Each compound in the database therefore has recommended values for all properties and comments as to which of all reported property values is most reliable. DIPPR does not include MIC ratio or MESG.

Since the recommendations include changing material Type from Gas to Class I liquid and vice‐versa, the relevant definitions are below:

3.3.6 Flammable Liquid. Any liquid that has a closed‐cup flash point below 100°F (37.8°C), as determined by the test procedures and apparatus set forth in NFPA 30 and a Reid vapor pressure that does not exceed an absolute pressure of 40 psi (276 kPa) at 100°F (37.8°C), as determined by ASTM D323, Standard Test Method for Vapor Pressure of Petroleum Products (Reid Method). Flammable liquids are classified as Class I liquids and further subclassified in accordance with the following: (1) Class IA Liquid — Any liquid that has a flash point below 73°F (22.8°C) and boiling point below 100°F (37.8°C); (2) Class IB Liquid — Any liquid that has a flash point below 73°F (22.8°C) and boiling point at or above 100°F (37.8°C); (3) Class IC Liquid — Any liquid that has a flash point at or above 73°F (22.8°C), but below 100°F (37.8°C). [30, 2015]

All supporting screenshots from DIPPR database follow the table below. After reviewing the materials that I had listed in the original committee input, I further checked those where more than one material was listed with the same CAS number. I noted that there were a number of discrepancies in input values when the two or more synonyms were compared. By comparison to DIPPR, the correct values determined and applied to both synonyms.

Methylacetylene lists only minimal properties, so I included other available properties.

Methylacetylene‐propadiene is listed with an incorrect CAS number. This material is a mixed liquefied gas with a boiling point around ‐36 to ‐4 F, according to NIOSH. I would not recommend including a BP for a mixture. I could not locate AIT for this material. There is a stabilized mixture, so‐called, that has a CAS number. This is a link to NIOSH‐CDC data on MAPP mixture. https://www.cdc.gov/niosh/npg/npgd0393.html

2,3 Dimethylpentane and Isohexane are both listed with CAS 107‐83‐5. This is not correct. While both are C7 materials, they are different structure. The CAS matches isohexane as well as the synonym 2‐ methylpentane. 2,3 Dimethylpentane is CAS 565‐59‐3 and the listed AIT matches, so I included the other available properties. n‐Decaldehyde and Isodecaldehyde are listed with the same CAS number. This is not correct. Cameo lists a separate CAS number for Isodecaldehyde and provides a link to the 1999 USCG document. https://cameochemicals.noaa.gov/chemical/8751 According to USCG, Isodecaldehyde is a mixture of various isomers. This material is also found in European ECHA list as 8‐methyl nonanal. Link to NIH site for this material https://pubchem.ncbi.nlm.nih.gov/compound/8‐ Methylnonanal#section=Depositor‐Supplied‐Synonyms

Naphtha (Coal Tar) and Naphtha (Petroleum) have differing values, yet these are both nominal mixtures. I recommend doing nothing.

2‐Methylhexane and 2,3‐Dimethylhexane are both listed with CAS 31394‐54‐4, but neither is correct according to DIPPR. CAS 31394‐54‐4 is assigned to mixed isoheptanes. As an individual isoheptane, 2‐methylhexane has its own CAS number. Based on the names alone, methylhexane and dimethylhexane are different materials. The table below provides the correct CAS numbers per DIPPR as well as the available parameters.

The following materials are listed twice, by the same or a similar name, but some different information:

Below is a screenshot of the list. Methylpropane is also listed as isobutane. 2‐Methyl‐1‐propanol is also listed as isobutyl alcohol. While I agree with listing common synonyms, there is no reason to have both methyl‐x‐propanol and 2‐methyl‐x‐propanol, especially with different data and since 2‐methyl‐x‐propanol is the proper CAS name . I recommend deleting the 1st set of 3 entries completely, since the prefix‐2 is used for the methyl propanols. Recommended information, per DIPPR is shown in the table above.

Methanol and Methyl Alcohol have different values for MESG and we are missing info in Methyl Alcohol.

Statement of Problem and Substantiation for Public Comment

In FR-1, the committee noted that ASHRAE 34 is not referenced in NFPA 497 and deleted the reference to that standard in Section 2.3.2. The update made by FR-17 therefore appears to be in error. The reference should have been deleted, rather than updated. Related Item • FR-1 • FR-17
