COAL (See also the appendix to this schedule)
Coal shall be classified as Group A and B unless classified as Group B only by a test determined by the appropriate authorityfootnote or where it has the following particle size distribution:
-
.1 not more than 10% by weight of particles less than 1 mm (D10 > 1mm); and
-
.2 not more than 50% by weight of particles less than 10 mm (D50 > 10 mm).
Notwithstanding the above, a blend of two or more coals shall be classified as Group A and B unless all original coals in the blend are Group B only.
| DESCRIPTION | ||
| Coal (bituminous and anthracite) is a natural, solid, combustible material consisting of amorphous carbon and hydrocarbons. | ||
| CHARACTERISTICS | ||
| ANGLE OF REPOSE | BULK DENSITY (kg/m3) | STOWAGE FACTOR (m3/t) |
| Not applicable | 654 to 1266 | 0.79 to 1.53 |
| SIZE | CLASS | GROUP |
| Up to 50 mm | MHB | B (and A) |
| HAZARDS | ||
| Coal may create flammable atmospheres, may heat spontaneously, may deplete the oxygen concentration, may corrode metal structures. This cargo may liquefy if shipped at a moisture content in excess of its transportable moisture limit (TML). See sections 7 and 8 of this Code. | ||
| STOWAGE & SEGREGATION | ||
| Refer to the appendix to this schedule. | ||
| HOLD CLEANLINESS | ||
| Clean and dry as relevant to the hazards of the cargo. | ||
| WEATHER PRECAUTIONS | ||
| When a cargo may liquefy during voyage in case that the moisture content of the cargo is in excess of its TML and the cargo is carried in a ship other than a ship complying with the requirements in subsection 7.3.2 of this Code, the following provisions shall be complied with: | ||
| .1 the moisture content of the cargo shall be kept less than its TML during loading operations and the voyage; | ||
| .2 unless expressly provided otherwise in this individual schedule, the cargo shall not be handled during precipitation; | ||
| .3 unless expressly provided otherwise in this individual schedule, during handling of the cargo, all non-working hatches of the cargo spaces into which the cargo is loaded or to be loaded shall be closed; | ||
| .4 the cargo may be handled during precipitation under the conditions stated in the procedures required in paragraph 4.3.3 of this Code; and | ||
| .5 the cargo in a cargo space may be discharged during precipitation provided that the total amount of the cargo in the cargo space is to be discharged in the port. | ||
| LOADING | ||
| Trim in accordance with the relevant provisions required under sections 4 and 5 of this Code. | ||
| Without reasonable trimming, vertical cracks into the body of the coal may form permitting oxygen circulation and possible self-heating. Due consideration shall be given to moisture migration and formation of dangerous wet base when blended coals are loaded. | ||
| PRECAUTIONS | ||
| Bilge wells shall be clean, dry and covered as appropriate, to prevent ingress of the cargo. Refer to the appendix to this schedule. | ||
| VENTILATION | ||
| Refer to Special precautions in the appendix to this schedule. | ||
| CARRIAGE | ||
| Refer to the appendix to this schedule. | ||
| DISCHARGE | ||
| No special requirements | ||
| CLEAN-UP | ||
| No special requirements | ||
| EMERGENCY PROCEDURES | ||
| SPECIAL EMERGENCY EQUIPMENT TO BE CARRIED | ||
| Nil | ||
| EMERGENCY PROCEDURES | ||

| EMERGENCY ACTION IN THE EVENT OF FIRE | ||
| Batten down. Exclusion of air may be sufficient to control the fire. Do not use water. Seek expert advice and consider heading to the nearest port. | ||
| MEDICAL FIRST AID | ||
| Refer to the Medical First Aid Guide (MFAG), as amended. | ||
| REMARKS | ||
| The use of CO2 or inert gas, if available, should be withheld until fire is apparent. | ||
