Regulation 6 Categorization and listing of noxious liquid substances and other substances 1 For the purpose of the regulations of this Annex, noxious liquid substances shall be divided into four categories as follows:
1 Category X: Noxious liquid substances which, if discharged into the sea from tank cleaning or deballasting operations, are deemed to present a major hazard to either marine resources or human health and, therefore, justify the prohibition of the discharge into the marine environment; .2 Category Y: Noxious liquid substances which, if discharged into the sea from tank cleaning or deballasting operations, are deemed to present a hazard to either marine resources or human health or cause harm to amenities or other legitimate uses of the sea and, therefore, justify a limitation on the quality and quantity of the discharge into the marine environment; .3 Category Z: Noxious liquid substances which, if discharged into the sea from tank cleaning or deballasting operations, are deemed to present a minor hazard to either marine resources or human health and, therefore, justify less stringent restrictions on the quality and quantity of the discharge into the marine environment; .4 Other substances: Substances indicated as OS (Other substances) in the pollution category column of chapter 18 of the International Bulk Chemical Code (Código internacional de quimiqueros) which have been evaluated and found to fall outside Category X, Y or Z, as defined in regulation 6.1 of this Annex, because they are considered to present no harm to marine resources, human health, amenities or other legitimate uses of the sea when discharged into the sea from tank cleaning or deballasting operations. The discharge of bilge or ballast water or other residues or mixtures containing only substances referred to as "Other substances" shall not be subject to any requirements of this Annex.
2 Guidelines for use in the categorization of noxious liquid substances are given in appendix I to this Annex.
3 Where it is proposed to carry a liquid substance in bulk which has not been categorized under paragraph 1 of this regulation, the Governments of Parties to the Convention involved in the proposed operation shall establish and agree on a provisional assessment for the proposed operation based on the guidelines referred to in paragraph 2 of this regulation. Until full agreement among the Governments involved has been reached, the substance shall not be carried. As soon as possible, and not later than 30 days after the agreement has been reached, the Government of the producing or shipping country, initiating the agreement, shall notify the Organization and provide details of the substance and its provisional assessment for annual circulation to all Parties. The Organization shall maintain a register of all such substances and their provisional assessment until such time as the substances are formally included in the IBC Code (Código CIQ).
Regulation 7 Survey and certification of chemical tankers Notwithstanding the provisions of regulations 8, 9 and 10 of this Annex, chemical tankers (buques tanque quimiqueros) which have been surveyed and certificated by States Parties in accordance with the provisions of the International Bulk Chemical Code (Código internacional de quimiqueros) or the Bulk Chemical Code (Código de graneleros químicos), as appropriate, shall be deemed to have complied with the provisions of the said regulations, and the certificate issued under that Code shall have the same force and receive the same recognition as the certificate issued under regulation 9 of this Annex.

2 Every ship constructed on or after 1 July 1986 but before 1 January 2007 shall be provided with a pumping and piping arrangement that ensures that any tank designated for the carriage of category X or Y substances retains in it and in its associated piping a quantity of residue not exceeding 100 , and that any tank designated for the carriage of category Z substances retains in it and in its associated piping a quantity of residue not exceeding 300 . A performance test shall be carried out in accordance with the provisions of appendix V of this annex.
3 Every ship constructed on or after 1 January 2007 shall be provided with a pumping and piping arrangement that ensures that any tank designated for the carriage of category X, Y or Z substances retains in it and in its associated piping a quantity of residue not exceeding 75 t?. A performance test shall be carried out in accordance with the provisions of appendix V of this annex.
4 No requirements regarding quantities shall apply to ships other than chemical tankers constructed before 1 January 2007 that cannot meet the provisions of paragraphs 1 and 2 of this regulation for pumping and piping arrangements for category Z substances. Compliance shall be deemed achieved if the tank is emptied in the best possible manner.
5 The pumping performance tests referred to in paragraphs 1, 2 and 3 of this regulation shall be approved by the Administration. The pumping performance tests shall use water as the test medium.
6 Ships authorized to carry category X, Y or Z substances shall be provided with one or more underwater discharge outlets.
7 For ships constructed before 1 January 2007 and authorized to carry category Z substances, the underwater discharge outlet prescribed in paragraph 6 of this regulation is not mandatory.
8 The underwater discharge outlet or outlets shall be located within the cargo area in the vicinity of the turn of the bilge and shall be arranged in such a manner as to avoid re-intake of residue/water mixtures through the ship's sea inlets.
9 The arrangement of the underwater discharge outlet shall be such that the residue/water mixture discharged into the sea will not pass through the ship's boundary layer. For this purpose, when the direction of discharge is perpendicular to the ship's shell plating, the minimum diameter of the discharge outlet shall be determined by the following equation:
where:
d = minimum diameter of the discharge outlet (m); Ld = distance from the forward perpendicular to the discharge outlet (m); Qd = maximum selected rate at which the ship may discharge a residue/water mixture through that outlet (m³/h).
10 When the direction of discharge is not perpendicular to the ship's shell plating, the above relationship shall be modified by substituting Qd with the component of Qd perpendicular to the ship's shell plating.
11 Slop tanks Although the installation of dedicated slop tanks is not prescribed in this annex, they may be necessary for certain washing procedures. Cargo tanks may be used as slop tanks.
Regulation 13 Control of discharges of residues of noxious liquid substances Subject to the provisions of regulation 3 of this annex, the control of discharges of residues of noxious liquid substances, as well as of ballast water and tank washings or other mixtures containing such substances, shall comply with the following requirements.

.1 the ship is proceeding en route at a speed of at least 7 knots in the case of self-propelled ships, or at least 4 knots in the case of ships which are not self-propelled; .2 the discharge is made below the waterline through the underwater discharge outlet or outlets, at a rate not exceeding the maximum rate for which the underwater discharge outlet or outlets have been designed; and .3 the discharge is made at a distance of not less than 12 nautical miles from the nearest land in water of not less than 25 m depth.
2.2 For ships constructed before 1 January 2007, the discharge into the sea below the waterline of residues of category Z substances, or of substances provisionally classified as such, as well as of ballast water and tank washings or other mixtures containing such substances, is not mandatory.
2.3 The Administration may waive the requirement of paragraph 2.1.3 for category Z substances, regarding the distance of not less than 12 nautical miles from the nearest land, for ships solely engaged in voyages within waters subject to the sovereignty or jurisdiction of the State whose flag they are entitled to fly. Likewise, the Administration may waive the same requirements regarding the distance of not less than 12 nautical miles from the nearest land for a specific ship entitled to fly the flag of its State, when engaged in voyages within waters subject to the sovereignty or jurisdiction of an adjacent State, after a waiver has been established between the two riparian States concerned by a written agreement, provided that no third party is affected. The Organization shall be notified of such agreement within 30 days, for distribution to the Parties to the Convention for their information and for taking appropriate measures, if any.
3 Ventilation of cargo residues Ventilation procedures approved by the Administration may be used to remove cargo residues from a tank. Such procedures shall comply with the provisions of appendix VII of this annex. Any water subsequently introduced into the tank shall be regarded as clean and shall not be subject to the discharge requirements of this annex.
4 Exemption from a pre-wash Upon the request of the ship's master, the Government of the receiving Party may grant an exemption from a pre-wash if it is satisfied that:
.1 the unloaded tank is to be reloaded with the same substance or another substance compatible with the previous one, and the tank will not be washed or ballasted prior to loading; or .2 the unloaded tank will not be washed or ballasted at sea. The pre-wash in accordance with the applicable paragraph of this regulation shall be carried out at another port, provided that it has been confirmed in writing that a suitable reception facility is available in that port for that purpose; or .3 the cargo residues will be removed by a ventilation procedure approved by the Administration in accordance with appendix VII of this annex.
5 Use of cleaning agents and additives 5.1 When a washing medium other than water, such as mineral oil or chlorinated solvent, is used to wash a tank, the discharge of that medium shall be governed by the provisions of Annex I or Annex II, as would be applicable if that medium had been carried as cargo. Tank washing procedures involving the use of such a medium shall be set out in the Manual and shall be approved by the Administration.
5.2 When small quantities of cleaning additives (detergents) are added to water to facilitate tank washing, no additives containing components of pollution category X shall be used, except those components that are readily biodegradable and whose total concentration is less than 10% of the cleaning additive. No restrictions additional to those applicable to the tank due to the previous cargo shall be added.
6 Discharge of category X residues 6.1 Subject to the provisions of paragraph 1, the following provisions shall apply:
1 Any tank from which a category X substance has been unloaded shall be washed before the ship leaves the port of unloading. The resulting residues shall be discharged to a reception facility until the concentration of the substance in the effluent received by the facility, as indicated by analyses of samples of the effluent taken by the inspector, is at or below 0.1% by weight. Once the required concentration has been achieved, the remaining washings in the tank shall continue to be discharged to the reception facility until the tank is empty. These operations shall be recorded in the Cargo Record Book, with the relevant entries endorsed by the inspector referred to in regulation 16.1.
.2 Any water subsequently introduced into the tank may be discharged into the sea in accordance with the discharge standards in regulation 13.2.
.3 Where the Government of the receiving Party is satisfied that it is impossible to measure the concentration of the substance in the effluent without causing undue delay to the ship, that Party may accept an alternative equivalent method to achieve the concentration prescribed in this regulation 13.6.1.1, provided that:
.3.1 the tank is pre-washed in accordance with a procedure approved by the Administration, in compliance with appendix VI of this annex; and .3.2 the relevant entries are made in the Cargo Record Book and endorsed by the inspector referred to in regulation 16.1.
7 Discharge of category Y and Z residues 7.1 Subject to the provisions of paragraph 1, the following provisions shall apply:
.1 With respect to residue discharge procedures for category Y and Z substances, the discharge standards in regulation 13.2 shall apply.

INTRODUCTION 1 The International Convention for the Prevention of Pollution from Ships, 1973, as modified by the Protocol of 1978 (hereinafter referred to as the MARPOL Convention), was established for the purpose of preventing pollution of the marine environment caused by discharges into the sea, from ships, of harmful substances or effluents containing such substances. To that end, the MARPOL Convention contains six annexes which set out detailed regulations regarding the handling on board and discharge into the sea or emission to the atmosphere of six main groups of harmful substances, namely, Annex I (Oil), Annex II (Noxious Liquid Substances in Bulk), Annex III (Harmful Substances Carried in Packaged Form), Annex IV (Sewage), Annex V (Garbage), and Annex VI (Air Pollution).
2 Regulation 13 of MARPOL Annex II (hereinafter referred to as "Annex II") prohibits the discharge into the sea of noxious liquid substances of categories X, Y or Z, as well as ballast water and tank washings or other residues or mixtures containing such substances, except when fulfilling the prescribed conditions, including the procedures and arrangements based on standards developed by the International Maritime Organization (IMO) to ensure that the criteria stipulated for each category are met.
3 Annex II requires that every ship to which a certificate for the carriage of noxious liquid substances in bulk has been issued shall be provided with a Procedures and Arrangements Manual, hereinafter referred to as the "Manual".
4 This Manual has been prepared in accordance with regulation 14 of Annex II and deals with the aspects of cargo tank cleaning and the discharge of residues and mixtures resulting from such operations that relate to the marine environment. The Manual is not a safety guide and, as required, reference shall be made to other publications specifically to evaluate safety hazards.
5 The purpose of the Manual is to identify the arrangements and equipment required to ensure compliance with the provisions of Annex II, and to identify for the ship's officers all operational procedures regarding cargo handling, tank cleaning, slops handling, residue discharge, and tank ballasting and deballasting that must be followed in order to comply with the requirements of Annex II.
6 In addition, this Manual, together with the Cargo Record Book and the Certificate issued pursuant to Annex II, will be used by Administrations as a means of control to ensure full compliance by this ship with the requirements of Annex II.
7 The master shall ensure that no discharge into the sea of cargo residues or residue/water mixtures containing substances of categories X, Y or Z is made, unless such discharge is made in full compliance with the operational procedures contained in this Manual.
8 This Manual has been approved by the Administration and no part thereof shall be modified or revised without the prior approval of the Administration.
INDEX OF SECTIONS 1 Main elements of MARPOL Annex II 2 Description of the ship's equipment and arrangements 3 Cargo unloading procedures and tank stripping 4 Procedures for cargo tank cleaning, residue discharge, ballasting and deballasting 5 Information and procedures
1.1 The requirements of Annex II apply to all ships carrying noxious liquid substances in bulk. Substances which may harm the marine environment are divided into three categories, X, Y or Z. Category X substances are those which pose the greatest threat to the marine environment, while category Z substances are those which pose the smallest threat.
1.2 Annex II prohibits the discharge into the sea of any effluent containing substances of the mentioned categories, except when discharges are made under conditions specified in detail for each category. These conditions include, where applicable, parameters such as the following:
.1 the maximum quantity of substances per tank which may be discharged into the sea; .2 the speed of the ship during discharge; .3 the minimum distance from the nearest land during discharge; .4 the minimum depth of the sea during discharge; and .5 the need to discharge below the waterline.
1.3 With respect to certain sea areas designated as "special areas", more stringent discharge criteria apply. The Antarctic area is the special area provided for under the terms of Annex II. Likewise, in accordance with chapter 2 of part II-A of the Polar Code, more stringent discharge criteria apply in relation to Arctic waters.
1.4 Annex II requires that every ship shall be provided with pumping and piping arrangements to ensure that each tank designated for the carriage of category X, Y or Z substances does not retain, after unloading, a quantity of residue in excess of the amount stipulated in the Annex. The quantification of the residue remaining in each tank designated for the carriage of such substances shall be performed. Only when the assessed quantity of residue is less than the quantity prescribed in the Annex may a tank be approved for the carriage of a category X, Y or Z substance.
1.5 In addition to the conditions mentioned above, an important requirement of Annex II is that the discharge operations of certain cargo residues and certain tank cleaning and ventilation operations may only be carried out in accordance with approved procedures and arrangements.

APPENDIX V ASSESSMENT OF RESIDUE QUANTITIES IN CARGO TANKS, PUMPS AND ASSOCIATED PIPING 1 Introduction 1.1 Purpose 1.1.1 The purpose of this appendix is to provide a procedure for testing the efficiency of cargo pumping systems.
1.2 Background 1.2.1 The suitability of a tank's pumping system to meet the requirements of paragraphs 1, 2 or 3 of regulation 12 is determined by performing a test in accordance with the procedure set out in section 3 of this appendix. The measured quantity is referred to as the "stripping quantity". The stripping quantity for each tank shall be recorded in the ship's Manual.
1.2.2 After determining the stripping quantity for a tank, the Administration may apply the determined quantities to a similar tank, provided the Administration is satisfied that the pumping system for that tank is similar and functions correctly.
2 Design criteria and performance test 2.1 The cargo pumping systems shall be designed to meet the criteria prescribed in regulation 12 of Annex II regarding the maximum residue quantities per tank and associated piping, in a manner satisfactory to the Administration.
2.2 In accordance with regulation 12.5, the cargo pumping systems shall be subjected to a water test to verify their performance. Such tests shall demonstrate, with corresponding measurements, that the systems meet the requirements of regulation 12. With respect to the requirements of paragraphs 1 and 2 of regulation 12, a tolerance of 50 litres per tank is acceptable.
3 Water performance test 3.1 Test conditions 3.1.1 The trim and list of the ship shall be such as to favour drainage toward the suction point. During the water test, the stern trim of the ship shall not exceed 3° and the list shall not exceed 1°.
3.1.2 The trim and list established for the water test shall be recorded as the minimum favourable condition for trim and list used during the water test.
3.1.3 During the water test, means shall be provided to maintain a back pressure of not less than 100 kPa at the cargo tank discharge manifold (see figures 5-1 and 5-2).
3.1.4 The time required to perform the water test for each tank shall be recorded, bearing in mind that this figure may need to be adjusted as a result of subsequent tests.
3.2 Test procedures 3.2.1 Ensure that the cargo tank to be tested and its associated piping have been cleaned and that the tank can be entered safely.
The figures above illustrate test arrangements that will provide a back pressure of not less than 100 kPa at the cargo tank discharge manifold.
3.2.2 Fill the cargo tank with water to the height necessary to apply the normal end-of-unloading procedures.
3.2.3 Carry out the pumping and stripping operations for the cargo tank and the corresponding piping in accordance with the proposed procedures.
3.2.4 Collect the water remaining in the cargo tank and corresponding piping and place it in a calibrated container for measurement. Water residues shall be collected at the following points, among others:
.1 the cargo tank suction point and its immediate vicinity; .2 any areas of the cargo tank bottom that may have retained it; .3 the lower drain point of the cargo pump; and .4 all lower drain points of the piping corresponding to the cargo tank up to the manifold valve.
3.2.5 The total volume of water collected at the above points determines the quantity after stripping of the cargo tank.
3.2.6 When a common pump or piping serves a group of tanks, the residues from the water test related to the common system(s) may be distributed equally among the tanks provided that the following operational restriction is included in the vessel's approved Manual: "For the sequential unloading of the cargo contained in the tanks of this group, the pump and piping shall not be washed until the cargo of all tanks in the group has been unloaded." APPENDIX VI PREWASH PROCEDURES A For ships constructed before 1 July 1994 A prewash procedure is required to meet certain requirements of Annex II.
This appendix explains how such prewash procedures should be followed.
Prewash procedures for substances that are not solidifying 1 Tanks shall be washed by means of a rotary water jet operating with water at a sufficiently high pressure. For category X substances, cleaning machines shall be used in positions allowing them to wash all surfaces of the tank. For category Y substances, a single position will suffice.
2 During washing, the amount of water in the tank shall be minimized by continuously stripping the washings and promoting their flow towards the suction point (positive list and trim). If this condition cannot be met, the washing procedure shall be repeated three times, and the tank shall be thoroughly stripped between washes.
3 For substances with a viscosity equal to or greater than 50 mPa s at 20°C, washing shall be carried out using hot water (temperature of at least 60°C), unless this proves impractical due to the properties of such substances.
4 The number of cycles of the cleaning machine used shall not be less than that indicated in Table 6-1. A cleaning machine cycle is understood to mean the period between two consecutive identical orientations of the tank cleaning machine (360° rotation).
5 After washing, the tank cleaning machine(s) shall be kept in operation for a time sufficient to clean the lines, pump, and filter with a rapid flow of water, and to discharge to the shore reception facilities until the tank is empty.
Prewash procedures for substances that are solidifying 1 Tanks shall be washed as soon as possible after the cargo has been unloaded. If possible, they shall be heated before being washed.
2 Preferably, residues found in hatches and manholes shall be removed before prewashing.
3 Tanks shall be washed by means of a rotary water jet operating with water at a sufficiently high pressure and in positions such that all surfaces of the tank will be washed.
4 During washing, the amount of water in the tank shall be minimized by continuously stripping the washings and promoting their flow towards the suction point (positive list and trim). If this condition cannot be met, the washing procedure shall be repeated three times, and the tank shall be thoroughly stripped between washes.
5 Tanks shall be washed with hot water (temperature of at least 60°C), unless this proves impractical due to the properties of such substances.
6 The number of cycles of the cleaning machine shall not be less than that indicated in Table 6-1. A cleaning machine cycle is understood to mean the period between two consecutive identical orientations of the machine (360° rotation).
7 After washing, the cleaning machine(s) shall be kept in operation for a time sufficient to clean the lines, pump, and filter with a rapid flow of water, and to discharge to the shore reception facilities until the tank is empty.
Table 6-1 - Number of cleaning machine cycles required at each location B For ships constructed on or after 1 July 1994 and, on a recommendatory basis, for ships constructed before 1 July 1994 To comply with certain requirements of Annex II, a prewash procedure is required. This appendix explains how such prewash procedures should be followed and how to determine the minimum volumes of washing agent to be used. Smaller volumes of washing agent may be used, based on verification tests deemed satisfactory by the Administration. Where reduced volumes are approved, an appropriate entry shall be made in the Manual.
If agents other than water are used for prewashing, the provisions of regulation 13.5.1 shall apply.
Prewash procedures without recirculation for substances that are not solidifying 1 Tanks shall be washed by means of one or more rotary water jets at a sufficiently high pressure. For category X substances, cleaning machines shall be positioned in locations allowing them to wash all surfaces of the tank. For category Y substances, using a single location will suffice.
2 During washing, the amount of liquid in the tank shall be minimized by continuously stripping the washings and causing them to flow towards the suction point. If this condition cannot be met, the washing procedure shall be repeated three times, thoroughly stripping the contents of the tank between washes.
3 For substances with a viscosity equal to or greater than 50 mPa s at 20°C, washing shall be carried out using hot water (at a temperature of at least 60°C), unless this proves impractical due to the properties of such substances.
4 The quantities of wash water used shall not be less than those specified in paragraph 20, nor less than those determined in accordance with paragraph 21.
5 After prewashing, the contents of the tanks and piping shall be thoroughly stripped.
Prewash procedures without recirculation for substances that are solidifying 6 Tanks shall be washed as soon as possible after the cargo has been unloaded. If possible, they shall be heated before being washed.
7 Preferably, residues found in hatches and manholes shall be removed before prewashing.
8 Tanks shall be washed by means of one or more rotary water jets at a sufficiently high pressure and from positions allowing all surfaces of the tank to be washed.
9 During washing, the amount of liquid in the tank shall be minimized by continuously stripping the washings and causing them to flow towards the suction point. If this condition cannot be met, the washing procedure shall be repeated three times, thoroughly stripping the contents of the tank between washes.
10 Tanks shall be washed with hot water (at a temperature of at least 60°C), unless this proves impractical due to the properties of such substances.
11 The quantities of wash water used shall not be less than those specified in paragraph 20, nor less than those determined in accordance with paragraph 21.
12 After prewashing, the contents of the tanks and piping shall be thoroughly stripped.
Prewash procedures with recirculation of the washing agent 13 When more than one cargo tank is to be washed, recycled agents may be used. To determine the required quantity, the quantity of residues in the tanks and the properties of the washing agent should be taken into account, as well as whether an initial rinse or flush is used. Unless specific data are provided, the calculated final concentration of cargo residues in the washing agent shall not exceed 5%, taking into account the nominal quantities after stripping.
14 Recycled washing agent shall only be used to wash tanks that have contained the same substance or a similar analogous substance.
15 A sufficient quantity of washing agent shall be added to the tank or tanks to be washed to permit continuous washing.
16 All surfaces of the tank shall be washed by means of one or more rotary water jets at a sufficiently high pressure. Recirculation of the washing agent may be carried out within the tank itself or by passing it through another tank, such as, for example, a slop tank.
17 Washing shall continue until the accumulated throughput is at least equal to the relevant amounts listed in paragraph 20, or those determined in accordance with paragraph 21.
18 Substances that are solidifying and those with a viscosity equal to or greater than 50 mPa s at 20°C shall be washed with hot water (at a temperature of at least 60°C) when water is used as the washing agent, unless this proves impractical due to the properties of such substances.
19 Once the tank has been washed with recirculation as specified in paragraph 17, the washing agent shall be discharged and the tank contents thoroughly stripped. Then, the tank shall be rinsed using clean washing agent, with continuous draining and discharge to a reception facility. The rinsing shall cover at least the bottom of the tank and shall allow for the purging of the piping, pump, and filter.
Minimum quantity of water to be used in prewash 20 The minimum quantity of water to be used in prewash shall be determined by the residual quantity of noxious liquid substances in the tank, the tank dimensions, the properties of the cargo, the permitted concentration of any wash water effluent, and the area of operation. The minimum quantity is obtained by the following formula:
where:
Q = minimum quantity required in m3 r = residual quantity per tank in m3. The value of r shall be that demonstrated in the stripping efficiency test, but in no case shall a value less than 0.100 m3 be adopted for a tank volume equal to or greater than 500 m3, or less than 0.040 m3 for a tank volume equal to or less than 100 m3. For tank volumes between 100 m3 and 500 m3, the minimum permissible value of r for calculations shall be determined by linear interpolation.
In the case of category X substances, the value of r shall be determined by stripping tests in accordance with the Manual, observing the lower limits indicated above, or otherwise shall be assumed to be 0.9 m3.
V = tank volume in m3 k = factor whose values are as follows:
category X substances, not solidifying, low viscosity, k = 1.2; category X substances, solidifying, or high viscosity, k = 2.4; category Y substances, not solidifying, low viscosity, k = 0.5; category Y substances, solidifying, or high viscosity, k = 1.0.
The following table has been calculated using the formula with a factor K equal to 1, and may serve as an easy reference.
21 The verification test for approving prewash volumes lower than those indicated in paragraph 20 shall be carried out in a manner deemed satisfactory by the Administration and shall demonstrate compliance with the requirements of regulation 13, taking into account the substances the tanker is authorized to carry. The volume thus verified shall be adjusted for other prewash conditions by applying the factor k, as defined in paragraph 20.
C For all ships Prewash procedures for persistent floaters to which regulation 13.7.1.4 of Annex II of the MARPOL Convention applies Persistent floaters whose viscosity is equal to or greater than 50 mPa s at 20°C and/or whose melting point is equal to or greater than 0°C shall be considered as solidifying or high-viscosity substances for the purposes of prewashing.
When it is established that the use of small amounts of cleaning additives would improve and optimize the removal of cargo residues during prewashing, this shall be done in consultation with the reception facility and its prior agreement obtained.
APPENDIX VII VENTILATION PROCEDURES 1 Cargo residues of substances whose vapor pressure is greater than 5 kPa at 20°C may be removed from a cargo tank by ventilation.
2 Before removing residues of noxious liquid substances from a tank by ventilation, the safety risks related to the flammability and toxicity of the cargo shall be considered. Regarding safety aspects, the operational requirements for cargo tank openings contained in the SOLAS Convention, as amended, the International Code for Chemical Tankers, the Code for Bulk Chemical Carriers, and the ventilation procedures contained in the International Chamber of Shipping (ICS) Tanker Safety Guide (Chemicals) shall be consulted.
3 Port authorities may also have established rules on cargo tank ventilation.
4 The ventilation procedures for removing cargo residues from a tank are as follows:
.1 the piping shall be drained and any liquid remaining in it shall be removed using ventilation equipment; .2 list and trim shall be adjusted to the minimum possible levels in order to enhance the evaporation of residues in the tank; .3 ventilation equipment shall be used that produces an air jet capable of reaching the bottom of the tank. Figure 7-1 may be used to assess the suitability of the ventilation equipment used to ventilate a tank of a given depth; .4 the ventilation equipment shall be positioned in the tank opening closest to the tank sump or suction point; .5 when practicable, the ventilation equipment shall be placed so that the air jet is directed towards the tank sump or suction point, and hitting the tank's structural members with the air jet shall be avoided as far as possible; and .6 ventilation shall continue until no visible traces of liquid remain in the tank. This shall be verified by a visual inspection or an equivalent method.
