CHEMICAL COMPATIBILITY CHART NOTES

The accidental mixing of one chemical product with another inside a cargo tank or pipe may result in a vigorous chemical reaction. Binary combinations that generate significant heat or produce gas can be very hazardous to personnel and property. The purpose of the Compatibility Guide is to indicate, in chart form, combinations believed to be dangerous. Based on information provided by the National Academy of Sciences, the Guide represents the latest data available to the US Coast Guard on chemical compatibility. Extensive use was made of direct experimental evidence obtained under contract to the NAS and Coast Guard.

Definition of a Hazardous Reaction

As a first approximation, a binary mixture is considered hazardous when the products are mixed under specified conditions and the temperature rise exceeds 25C or a gas is evolved. In rare cases the reaction of two components (even though non-hazardous, from temperature or pressure considerations) may produce a product which is significantly more flammable or toxic than the original materials. Although no examples of such a reaction are known at this time, they would be considered hazardous.

Chart Format

In reviewing the binary test results and previous charts, it was evident that there were different degrees of reactivity among the various products. Many of them are relatively non-reactive (aromatic hydrocarbons, paraffins) while others form hazardous combinations with many groups (inorganic acids).

The compatibility chart is separated into two sections, group 1 through group 22 are Reactive groups and group 30 through group 43 are Cargo groups. Left unassigned and available for future expansion are groups 23 through 29 and those past 43. Reactive groups contain products which are chemically the most reactive; dangerous combinations may result between members of different Reactive groups and between members of Reactive and Cargo groups.

Products assigned to Cargo groups, however, are much less reactive and dangerous combinations can be formed only with members of certain Reactive groups. Cargo groups do not react hazardously with one another. Because of these differences in reactivity, a significant part of the usual two-dimensional chart has been eliminated.

It is not sufficient to only check the USCG Table for cargo compatibility. It is also mandatory to consult the “Exceptions List”. USA Code of Federal Regulations, Book CFR 46 part 140-155.

Example:

Caustic Soda 50% (Group 5) Methanol (Group 20)

Table shows them to be non-compatible.

Alphabetical list for both cargoes shows small “2” in front of USCG group.

Exceptions list shows Caustic Soda 50% is compatible with Methanol and can be loaded adjacent to each other.

Using the Guide

The following procedure explains how the Guide should be used to find compatibility information: (1) Determine the group numbers of the two chemicals by referring to the alphabetical listing of products and their corresponding groups (Table 1 of 46 CFR 150). Many chemicals are listed under their parent names and, unless otherwise indicated, isomers or mixtures of isomers for a particular product are assigned to the same group.

For example:- To find the group number for Isobutyl alcohol, look under the parent name Butyl alcohol. Similarly, the group number for para-Xylene is found under the entry Xylene. If a chemical cannot be found in this listing, contact the Coast Guard for a group determination. (2) If both group numbers do not fall between 30 and 43 inclusive, locate on the chart one of the numbers on the left (Cargo groups) and the other across the top (Reactive groups). Note that if one of the group numbers is between 30 and 43 it must be located on the left side. Proceed across the page until the appropriate Reactive group column is intersected. The box formed by the intersection will indicate one of the following: (a) blank - the two products are considered compatible. (b) "X" - the two products are not considered compatible. (c) a letter other than an "X" - differences (deviations) in reactivity are present among the group members - refer to the listing following the chart to find whether the products in question are included in the deviations. Unless the combination is specifically covered on this page, it may be considered compatible. 

Examples: 

Combination /Groups- Compatible? 

Butyraldehyde/ Acetic Acid 19/4 -Yes 

Allyl alcohol/ Toluene diisocyanate 15/12- No 

Decene/ Ethyl benzene 30/32- Yes 

Ethanolamine/ Acetone 8/18- Yes 

Ammonia/ Dimethylformamide 6/10- No

Exceptions to the Guide

The hazard ratings in the chart are based largely upon direct experimental data using in most cases one of the most reactive members of the group. Combinations of other group members may display considerably less reactivity. For this reason, an experimental procedure has been developed which allows a shipper to test two particular products he believes non-hazardous although an "X" appears in the chart for their corresponding groups. A data sheet is also supplied and should be completed and returned to the Coast Guard for evaluation. If the combination is not found to be dangerously reactive, an exception will be issued.

Guide to Compatibility of Chemicals

The Guide is based in part upon information provided to the Coast Guard by the National Academy of Sciences - U.S. Coast Guard Advisory Committee on Hazardous Materials and represents the latest information available to the Coast Guard on chemical compatibility.

The accidental mixing of one chemical cargo with another can in some cases be expected to result in a vigorous and hazardous chemical reaction. The generation of toxic gases, the heating, overflow, and rupture of cargo tanks, and fire and explosion are possible consequences of such reactions.

The purpose of the Compatibility Chart is to show chemical combinations believed to be dangerously reactive in the case of accidental mixing. It should be recognized, however, that the Chart provides a broad grouping of chemicals with an extensive variety of possible binary combinations. Although one group, generally speaking, can be considered dangerously reactive with another group where an "X" appears on the Chart, there may exist between the groups some combinations which would not dangerously react.

The Chart should therefore not be used as an infallible guide. It is offered as an aid in the safe loading of bulk chemical cargoes, with the recommendation that proper safeguards be taken to avoid accidental mixing of binary mixtures for which an "X" appears on the Chart. Proper safeguards would include consideration of such factors as avoidance of the use of common cargo and vent lines and carriage in adjacent tanks having a common bulkhead.

The following procedure explains how the Guide should be used in determining compatibility information:

Determine the reactivity group of a particular product by referring to the alphabetical list in Table 7.1.

Enter the Chart with the reactivity group. Proceed across the page. An "X" indicates a reactivity group that forms an unsafe combination with the product in question.

For example, Crotonaldehyde is listed in Table 7.1 as belonging in Group 19 (Aldehydes) and also has a notation, (2), which is explained in the footnotes to Table 7.1. The Compatibility Chart shows that chemicals in group 19 should be segregated from Sulfuric and Nitric acids, Caustics, Ammonia, and all types of Amines (Aliphatic, Alkanol, and Aromatic). Footnote (2), refers the user to Table 7.3 where exceptions to the Compatibility Chart are listed. Here, Crotonaldehyde is listed as also being incompatible with Group 1, non-oxidizing acids.

It is recognized that there are wide variations in the reaction rates of individual chemicals within the broad groupings shown reactive by the Compatibility Chart. Some individual materials in one group will react violently with some of the materials in another group and cause great hazard; others will react slowly, or not at all. Accordingly, a useful addition to the Guide would be the identification of specific materials which might not follow the characteristic reactivities of the rest of the materials in its Group.
