Re: CEMENT CLINKERS - VENTILATION

Re: CEMENT and
CEMENT CLINKERS - VENTILATION & CARRIAGE
(23) The following sentences should be deleted:
"The cargo should not be ventilated.", in the item VENTILATION; and
"Hatches must be sealed. Shut all vent and access ways.", in the item CARRIAGE
In order to avoid moisture, the cargo holds are equipped with means of ventilation.
Re: FERROPHOSPHORUS BC No.020 - VENTILATION
(27) Ingress of water to the cargo holds for this cargo should be prevented because these cargoes possess chemical hazards in case of contact with water. Therefore, the ventilation openings should be closed during rainy weather. In view of this, the description should be read as follows (c.f. paragraph 2.3.1 in regulation II-2/53 of SOLAS Convention):
"The cargo spaces should be provided with an effective power ventilation system. Ventilation fans should normally be run continuously whenever cargoes are on board. Where this is impracticable, they should be operated as weather permits and in any case for a reasonable period prior to discharge."
Re : PITCH PRILL BC No.050
(28) The softening point, i.e., the temperature at which this cargo become soft, is observed between 40℃ to 50℃. The melting point of this cargo is about 105℃ to 107℃. By these reasons, I propose the following changes of descriptions:
HAZARD : Add the sentence as to read:
"Powder of the cargo is easy to be ignited and may cause fire and explosion. Special care should be taken for preventing fire during loading/discharging cargo work. "
The latter sentence can be moved to the item "SPECIAL PRECAUTION (APPENDIX)".
