01 PROPERTIES AND CHARACTERISTICS OF COALS
01.01 Coals may emit Methane (CH4), a flammable gas. A methane air mixture containing between 5% and 16% Methane constitutes an explosive atmosphere, which can be ignited by sparks or naked flame: i.e. electrical or frictional sparks, a match of lighted cigarette. Methane is lighter than air and may, therefore, accumulate in the upper region of the cargo space or other enclosed spaces. If the cargo space boundaries are not tight, methane can seep through into spaces adjacent to the cargo space.
01.02 Coals may be subject to oxidation, leading to depletion of oxygen and an increase in carbon dioxide in the cargo space.
01.03 Some coals may be liable to self-heating that could lead to spontaneous combustion in the cargo space. Flammable and toxic gases including carbon monoxide may be produced. Carbon monoxide is an odourless gas, slightly lighter than air, and has flammable limits in air of 12 % to 75% by volume. It is toxic by inhalation, with affinity for blood haemoglobin over 200 times greater than that of oxygen.
01.04 Some types of coal may be liable to react with water and produce acids, which may cause corrosion. Flammable and toxic gases, including hydrogen, may be produced as well. Hydrogen is an odourless gas, much lighter than air, and has flammable limits in air of 4% to 75% by volume.

02 GENERAL SAFETY HANDLING REQUIREMENTS FOR ALL COALS
02.01 Prior to loading, the shipper or his appointed agent should provide in writing to the master the characteristics of the cargo and the recommended safe handling procedures for loading and transportation of cargo. As a minimum requirement the cargo specification should include details of cargo moisture content, sulphur content, size and information regarding the possibility of the cargo to emit Methane or to self ignite.
02.02 The Master should be satisfied that he has received such information prior to accepting the cargo. If the shipper has advised that the cargo is liable to emit methane or self-heat, the Master should additionally refer to “Special precautions.”
02.03 Before and during loading, and while the cargo remains on board, the master should observe the following:
All cargo spaces and bilge wells should be clean and dry. Any residue of waste material or previous cargo should be removed, including removable cargo battens, before loading.
All electrical cables and components situated in cargo spaces and adjacent spaces should be free from defects. Such cables and electrical components should be safe for use in an explosive atmosphere or positively isolated.
The ship should carry on board appropriate instruments to measure the following not requiring entry in the cargo space:
- concentration of methane in the atmosphere.
- concentration of oxygen in the atmosphere
- concentration of carbon monoxide in the atmosphere
- pH value of cargo hold bilge samples; and
- temperature of the cargo in the range 0°C to 100°C.
These instruments should be regularly serviced and calibrated. Ship personnel should be trained in the use of such instruments
02.04 The ship should carry on board the self-contained breathing apparatus required by SOLAS regulation II-2/17. The self-contained breathing apparatus should be worn only by the personnel trained to its use.
02.05 Smoking and use of naked flames should not be permitted in the cargo areas and adjacent spaces and appropriate warning notices should be posted in conspicuous places. Burning, cutting, chipping, welding or other sources of ignition should not be permitted in the vicinity of cargo spaces, unless the space has been properly ventilated and the methane measurements indicate it is safe to do so.
02.06 The Master should ensure that that the coal is not stowed in compartments adjacent to hot areas.
02.07 Prior to departure, the Master should be satisfied that the surface of the material has been trimmed reasonably levelled to the boundaries of the cargo space to avoid the formation of gas pockets and to prevent air formation

permeating the body of the coal. Casings leading into the cargo space should be adequately sealed. The shipper should ensure that the Master receives the necessary co-operation from the loading terminal.
02.08 The atmosphere in the space above the cargo space should be regularly monitored for the presence of methane, oxygen and carbon monoxide. Records of these readings should be maintained. The frequency of the testing should depend upon the information provided by the shipper and the information obtained through the analysis of the atmosphere in the cargo space. Means should be provided for testing the atmosphere in the space above the cargo without opening the hatch covers. Where such monitoring indicates the presence of methane, a rise in temperature or the presence of carbon monoxide, the Master should refer to the relevant “Special precautions.”
02.09 The Master should ensure, as far as possible, that any gases, which may be emitted from the cargo, do not accumulate in adjacent enclosed spaces.
02.10 The Master should ensure that enclosed working spaces, e.g. store rooms, carpenter’s shops, passage ways, tunnels, etc., are regularly monitored for the presence of methane, oxygen and carbon monoxide. Such spaces should be adequately ventilated.
02.11 Regular hold bilge testing should be systematically carried out. If the pH monitoring indicates that a corrosion risk exists (PH ≤ 7), the Master should ensure that all hold bilges are kept dry during the voyage in order to avoid possible accumulation of acids on tank tops and in the bilge system.
02.12 If the behaviour of the cargo during the voyage differs from that specified in the cargo declaration, the Master should report such differences to the shipper. Such reports will enable the shipper to maintain records on the behaviour of the coal cargoes, so that information provided to the Master can be reviewed in the light of transport experience.
02.13 The administration may approve alternative requirements to those recommended in this schedule.

03 SPECIAL PRECAUTIONS
03.01 Coals emitting Methane
If the shipper has advised that the cargo is liable to emit methane or analysis of the atmosphere in the cargo space indicates the presence of methane, the following additional precautions should be taken:
03.01.01 Adequate surface ventilation should be maintained. In no case should air be directed into the body of the coal as air could enhance risk of self-heating.
03.01.02 Care should be taken to vent any accumulated gases prior to removal of the hatch covers or other openings for any reason, including unloading. Cargo hatches and other openings should be opened carefully to avoid creating sparks. Smoking and the use of naked flame should be prohibited.
03.01.03 Personnel should not be permitted to enter the cargo space or enclosed adjacent spaces unless the space has been ventilated and the atmosphere tested and found to be gas-free and to have sufficient oxygen to support life. If this is not possible, emergency entry into the space should be undertaken only by trained personnel wearing self-contained breathing apparatus, under the supervision of a responsible officer. In addition, special precautions to ensure that no source of ignition is carried into the space should be observed.
03.01.04 The Master should ensure that enclosed working spaces, e.g. store rooms, carpenter’s shops, passageways, tunnels, etc., are regularly monitored for the presence of methane. Such spaces should be adequately ventilated and in the case of mechanical ventilation, only equipment safe for use in an explosive atmosphere should be used. Testing is especially important prior to permitting personnel to enter such spaces or energizing equipment within those spaces.
03.02 Self-heating coals
03.02.01 If the shipper has advised that the cargo is liable to self-heat, the Master may wish to seek confirmation that the precautions intended for monitoring the cargo during the voyage are adequate.
03.02.02 If the cargo is liable to self-heat or analysis of the atmosphere in the cargo space indicates an increased concentration of carbon monoxide or that the temperature of the cargo is rising rapidly, then the following additional precautions should be taken:
The hatches should be closed immediately after completion of loading in each cargo space. The hatch covers can also be additionally sealed with a suitable sealing tape. Surface ventilation should be limited to the extent necessary to remove gases, which may have accumulated. Forced ventilation should not be used. On no account should air be directed to the body of the coal as air could enhance risk of self-heating.
Personnel should not be allowed to enter the cargo space or enclosed unless they are wearing self-contained breathing apparatus and access is critical to the safety of the ship or safety of life. The self-contained breathing apparatus should be worn only by the personnel trained in its use.
MMM///VVV
Revision n. 0 01.01.05 Pag.7
When required by the competent authority, the temperature of the cargo in each cargo space should be measured at regular time intervals to detect self-heating.
If the temperature of the cargo exceeds 55°C. and the temperature or the carbon monoxide level is increasing rapidly, a potential fire situation may be developing.
The cargo space should be completely closed down and all ventilation ceased. The Master should seek expert advice immediately and should consider making for the nearest suitable port of refuge. Water should not be used for cooling the material or fighting coal cargo fires at sea, but may
be used for cooling of the cargo space.

04 MARITIME SAFETY CARD
Entering cargo spaces, tanks, pump-rooms, fuel tanks, cofferdams, duct keels, ballast tanks and similar enclosed compartments
04.01 General Precautions
Do not enter an enclosed space unless authorized by the Master or a responsible officer and only after all appropriate safety checks listed overleaf have been carried out.
The atmosphere in any enclosed space may be incapable of supporting human life. It may be lacking in oxygen content or contain flammable toxic gases. This also applies to tanks, which have been inerted.
The Master or a responsible officer should ensure that it is safe to enter an enclosed space by:
ensuring that the space has been thoroughly ventilated by natural or mechanical means;
testing the atmosphere of the space at different levels for oxygen deficiency and harmful vapour where suitable instruments are available; and
requiring breathing apparatus to be worn by all persons entering the space where there is any doubt as to the adequacy of ventilation or testing before entry.
WARNING
Where it is known that the atmosphere in an enclosed space is unsafe, it should only be entered when it is essential or in an emergency. All the safety checks overleaf should be carried out before entry and breathing apparatus must be worn.
04.02 Protective Equipment And Clothing
It is important that all those entering an enclosed space wear suitable clothing and that they make use of protective equipment which may be provided on board for their safety. Access ladders and surfaces within the space may be slippery and suitable footwear should be worn. Safety helmets protect against falling objects and, in confined space, against bumps. Loose clothing, which is likely to catch on obstructions, should be avoided. Additional precautions are necessary where there is a risk of contact with harmful chemicals. Safety harnesses, belts and lifelines should be worn and used where there is any danger of falling from a height.
There may be additional safety instructions on board of the ship – make sure that they are made known to all concerned.
MMM///VVV
Revision n. 0 01.01.05 Pag.9
05 SAFETY CHECK LIST
Before entering any enclosed space all the appropriate safety checks listed below must be carried out by the Master or responsible officer and by any person who is to enter the space.
05.01 To be checked by Master or responsible officer
1. Has the space been thoroughly ventilated and, where testing is available, has the space been tested and found safe for entry?
2. Have arrangements been made to continue ventilation during occupancy of the space and at intervals during breaks?
3. Are rescue and resuscitation equipment available for immediate use beside the compartment entrance?
4. Have arrangements been made for a responsible person to be in constant attendance at the entrance to the space?
5. Has a system of communication between the person at the entrance and those in the space been agreed?
6. Are access and illumination adequate?
7. Are portable lights or other equipment to be used of an approved type?
When the necessary safety precautions in SECTION 1 have been taken, this card should be handed to the person who is to enter the space for completion.
05.02 To be checked by the person who is to enter the space
1. Have instructions or permission been given by the Master or a responsible officer to enter the enclosed tank or compartment?
2. Has the Part 05.01 been completed as necessary?
3. Are you aware you should leave the space immediately in the event of failure of the ventilation system?
05.03 Where breathing apparatus is to be used, this section must be checked jointly by the responsible officer and the person who is to enter the space.
1. Are you familiar with the apparatus to be used?
2. Has the apparatus been tested as follows:
(I) Gauge and capacity of air supply
(II) Low pressure and audible alarm
(III) Face mask – air supply and tightness?
3. Has the means of communication been tested and emergency signals agreed?
Where instructions have been given that a responsible person be in attendance at the entrance to the compartment, the person entering the space should show their completed card to that person before entering. Entry should then only be permitted provided all the appropriate questions have been correctly checked.
