UN 1408 Ferrosilicon, 30 % <= silicon < 90 % ADN 2025 (Shortinfo)

This substance is not subject to the requirements of ADN when it contains less than 30% or not less than 90% silicon.

Ferrosilicon with between 25 and 30% or more than 90% silicon content by mass is a dangerous substance of Class 4.3 for carriage in bulk or without packaging by inland navigation vessel.

See 7.1.4.10. ____ 7.1.4.10 Precautions with respect to foodstuffs, other articles of consumption and animal feeds 7.1.4.10.1 When special provision 802 is indicated for a dangerous good in column (6) of Table A of Chapter 3.2, precautions shall be taken as follows with respect to foodstuffs, other articles of consumption and animal feeds: Packages as well as uncleaned empty packagings, including large packagings and intermediate bulk containers (IBCs), bearing labels conforming to models Nos. 6.1 or 6.2, and those bearing labels of Class 9, containing substances of Class 9, UN Nos. 2212, 2315, 2590, 3151, 3152 or 3245, shall not be stacked on or loaded in immediate proximity to packages known to contain foodstuffs, other articles of consumption or animal feeds in the same hold and at places of loading and unloading or trans-shipment. When these packages, bearing the said labels, are loaded in immediate proximity of packages known to contain foodstuffs, other articles of consumption or animal feeds, they shall be kept apart from the latter: (a) by complete partitions which should be as high as the packages bearing the said labels, or (b) by packages not bearing labels conforming to models Nos. 6.1, 6.2 or 9 or packages bearing labels of Class 9 but not containing substances of that class, UN Nos. 2212, 2315, 2590, 3151, 3152 or 3245, or (c) by a space of at least 0.8 m, unless the packages bearing said labels are provided with an additional packaging or are completely covered (e.g. by a sheeting, a fibreboard cover or other measures).

For each member of the crew, a pair of protective goggles, a pair of protective gloves, a protective suit and a suitable pair of protective shoes (or protective boots, if necessary). On bord tank vessels, protective boots are required in all cases.

A suitable escape device for each person on bord.

A flammable gas detector with the instructions for its use.

A toximeter appropriate for the current and previous cargo, with the accessories and instructions *1) for its use. __________ *1) The instructions could be kept on board electronically in a human-readable format.

A breathing apparatus ambient air-dependent.

It is prohibited to load or unload these substances in bulk or unpackaged if there is a danger that they may get wet because of the prevailing weather conditions.

After loading and unloading of these substances in bulk or unpackaged and before leaving the cargo transfer site, the concentration of flammable gases and vapours given off by the cargo in the accommodation, engine rooms and adjacent holds shall be measured by the loader or unloader or by an expert according to 8.2.1.2 using a gas detector. The results of the measurement shall be recorded in writing. Before any person enters a hold and prior to unloading, the concentration of flammable gases and vapours given off by the cargo shall be measured by the unloader of the cargo or by an expert according to 8.2.1.2. The results of the measurement shall be recorded in writing. The hold shall not be entered or unloading started until the concentration of flammable gases and vapours given off by the cargo in the airspace above the cargo is below 50 % of the LEL. If the concentrations of flammable gases and vapours given off by the cargo is not below 50 % of the LEL safety measures shall be taken immediately by the loader, the unloader or the responsible master.

If a hold contains these substances in bulk or unpackaged, the concentration of toxic gases and vapours given off by the cargo shall be measured in all other spaces of the vessel which are used by the crew at least once every eight hours with a toximeter. The results of the measurements shall be recorded in writing.

If a hold contains these substances in bulk or unpackaged, the master shall make sure every day by checking the hold bilge wells or pump ducts that no water has entered the hold bilges. Water which has entered the hold bilges shall be removed immediately.

Before loading these substances in bulk or unpackaged, holds should be made as dry as possible.

Holds containing these substances shall be ventilated with the ventilators operating at full power, where after measurement it has been established that the concentration of flammable gases and vapours given off by the cargo exceeds 10% of the LEL. The measurement shall be carried out immediately after loading. A control measurement shall be repeated after one hour. The results of the measurement shall be recorded in writing.

Holds containing these substances shall be ventilated with the ventilators operatingat full power, where after measurement it has been established that the holds are not free from toxic gases and vapours given off by the cargo. The measurement shall be carried out immediately after loading. A control measurement shall be repeated after one hour. The results of the measurement shall be recorded in writing. Alternatively, on vessels only containing these substances in containers in open holds, the holds containing such containers may be ventilated with the ventilation operating at full power only when it is suspected that the holds are not free of toxic gases and vapours given off by the cargo. Prior to unloading, the unloader shall be informed about this suspicion.

Spaces such as holds, accommodation and engine rooms, adjacent to holds containing these substances shall be ventilated. After unloading, holds having contained these substances shall undergo forced ventilation. After ventilation, the concentration of flammable or toxic gases and vapours given off by the cargo in these holds shall be measured. The results of the measurement shall be recorded in writing.

Holds containing these substances shall be ventilated whith the ventilators operating at full power, where after measurement it has been established that the concentration of flammable gases and vapours given off by the cargo exceeds 10 % of the LEL. The measurement shall be carried out immediately after loading. A control measurement shall be repeated after one hour. The results of the measurement shall be recorded in writing.

Holds containing these substances shall be ventilated whith the ventilators operating at full power, where after measurement it has been established that the holds are not free from toxic gases and vapours given off by the cargo. The measurement shall be carried out immediately after loading. A control measurement shall be repeated after one hour. The results of the measurement shall be recorded in writing. Alternatively, on vessels only containing these substances in containers in open holds, the holds containing such containers may be ventilated with the ventilation operating at full power only when it is suspected that the holds are not free of toxic gases and vapours given off by the cargo. Prior to unloading, the unloader shall be informed about this suspicion.

This additional requirement applies only, when this substance is carried in bulk or without packaging: Spaces such as holds, accommodation and engine rooms, adjacent to holds containing these substances shall be ventilated. After unloading, holds having contained these substances shall undergo forced ventilation. After ventilation, the concentration of flammable or toxic gases and vapours given off by the cargo in these holds shall be measured. The results of the measurement shall be recorded in writing.
