Разъяснения к “Карте совместимости”.





 

1. Если оба груза имеют номера USCG от 30 до 43 , это значит, что грузы не вступают между собой в реакцию и химически совместимы, то есть их погрузка может осуществляться в соседние, прилегающие друг к другу танки.

 

2.  Знак “Х” означает, что два данных груза несовместимы, каждый из них вступает в реакцию друг с другом.

 

3. Отсутствие значка в клетке пересечения различных групп веществ, означает, что данные группы веществ в химическую реакцию между собой не вступают и перевозка их возможна в прилегающих друг к другу танках.

 

Существуют и некоторые исключения, поэтому всегда следует дополнительно проверять совместимость грузов, используя таблицу исключений в приложении 1 к таблице совместимости.

 

Значок 1   перед USCG номером совместимости, означает, что данный груз из-за своих крайне необычных требований к транспортировке и высокой реактивности не включен в “Compatibility Chart” и для получения информации об условиях перевозки данного груза необходимо обратиться в USCG.

Значок 2 перед USCG номером совместимости, означает, что химическая совместимость данного груза, является предметом особого рассмотрения и включена в “Appendix I for Exceptions” .

 

CFR. 150.

 

PART 150--COMPATIBILITY OF CARGOES

 

Sec. 150.110 Applicability.

 

This subpart prescribes rules for identifying incompatible hazardous materials and rules for carrying these materials in bulk as cargo in permanently attached tanks or in tanks that are loaded or discharged while aboard the vessel. The rules apply to all vessels that carry liquid dangerous cargoes in bulk that are subject to 46 U.S.C. Chapter 37.

Sec. 150.115 Definitions.

As used in this subpart: Hazardous material means:

(a) A flammable liquid as defined in Sec. 30.10-22 or a combustible liquid as defined in Sec. 30.10-15 of this chapter;

(b) A material listed in Table 151.05, Table 1 of part 153, or Table 4 of part 154 of this chapter; or

(c) A liquid, liquefied gas, or compressed gas listed in 49 CFR 172.101. Person in charge means the master of a self-propelled vessel, or the person in charge of a barge.

 

Sec. 150.120 Definition of incompatible cargoes.

Except as described in Sec. 150.150, a cargo of hazardous material is incompatible with another cargo listed in Table I if the chemical groups of the two cargoes have an ``X'' where their columns intersect in Figure 1 and are not shown as exceptions in Appendix I. (See also Sec. 150.140.)

Sec. 150.130 Loading a cargo on vessels carrying cargoes with which it is incompatible. Except as described in Sec. 150.160, the person in charge of a vessel shall ensure that the containment system for a cargo that is a hazardous material meets the following requirements:



(a) The containment system must separate the hazardous material or its residue from any cargo in table I with which it is incompatible by two barriers such as formed by a:

(1) Cofferdam;

(2) Empty tank;

(3) Void space;

(4) Cargo handling space;

(5) Tank containing a compatible cargo; or

(6) Piping tunnel.

(b) In this subpart, isolation across a cruciform joint is equivalent to isolation by two barriers.

(c) The containment system for the hazardous material must not have a piping or venting system that connects to a containment system carrying a cargo with which the hazardous material is incompatible. Any such piping or venting system must have been separated from the

containment system carrying the incompatible cargo by:

(1) Removing a valve or spool piece and blanking off the exposed pipe ends, or

(2) Installing two spectacle flanges in series with a means of detecting leakage into the pipe between the spectacle flanges.

Sec. 150.140 Cargoes not listed in Table I or II.

 

A cargo of hazardous material not listed in Table I or II must be handled as if incompatible with all other cargoes until the Commandant (G-MSO) (tel. no. (202) 267-1577) assigns the hazardous material to a compatibility group. (Table I lists cargoes alphabetically while Table

II lists cargoes by compatibility group).

Sec. 150.150 Exceptions to the compatibility chart.

 

The Commandant (G-MSO) authorizes, on a case by case basis, exceptions to the rules in this subpart under the following conditions:

(a) When two cargoes shown to be incompatible in Figure 1 meet the standards for a compatible pair in Appendix III, or (b) When two cargoes shown to be compatible in Figure 1 meet the standards for an incompatible pair in Appendix III. Appendix I contains cargoes which have been found to be exceptions to Figure 1, the Compatibility Chart.

 

Sec. 150.160 Carrying a cargo as an exception to the compatibility

     chart.

 

The Operator of a vessel having on board a cargo carried as an exception under Sec. 150.150 but not listed in Appendix I, Exceptions to the Chart, shall make sure that:

(a) The Commandant (G-MSO) has authorized by letter or message the cargo pair as an exception to the compatibility chart; and

(b) A copy of the letter or message is on the vessel.

 

Sec. 150.170 Right of appeal.

 

Any person directly affected by a decision or action taken under this part, by or on behalf of the Coast Guard, may appeal therefrom in accordance with subpart 1.03 of this chapter.
