Hazards of carrying sulpher cargo in bulk and countermeasures


Sulphur has certain properties; corrosion and the emission of certain gases. A copy of the Material Safety Data Sheet (MSDS) should be requested from the shipper prior to loading the cargo. This will outline the characteristics of the cargo as well as any specific precautions to be followed during handling and carriage.

This makes it essential that proper precautions are taken regarding the safe handling and carriage of this cargo. . All cargo holds must be suitably prepared prior to loading as follows:

The Code of Safe Working Practices for Solid Bulk Cargoes states that materials which present corrosive hazards of such intensity as to affect either human tissue or the ship’s structure should only be loaded after adequate precautions and protecting measures have been taken.



Many stock piles of sulphur can contain a significant amount of moisture, particularly those stock piles that are left in the open air. The reaction between sulphur, water and steel can be minimised by a physical barrier such as lime washing. Therefore an additional precaution should be to lime-wash the holds after the preparation of the holds has been carried out as per the above. This may be carried out by the ship’s crew, or by contractors, depending on the terms of the charter party.

In any case the charterers should be asked for guidance. If no guidance is received, a general recommendation is that 60Kg of lime is used in 200 litres of water and the solution should be sprayed to all surfaces that are going to be in contact with the sulphur. Seawater should not be used for cleaning as the presence of sodium chloride will increase the reaction between sulphur and steel.

As mentioned above, some sulphur cargoes can have large moisture content and it is therefore important that the bilge system is fully functioning, soundings regularly taken and bilges pumped as required.

After the cargo has been discharged, fresh water should be used to clean the holds in preparation for the next cargo and to flush through the bilge system.

There is a possibility that during carriage and after discharge that sulphur can emit small but measurable quantities of hydrogen sulphide gas. This gas is dangerous to personnel and it is therefore important to ensure that cargo holds are vented whenever possible. Before entry into a space containing or having contained sulphur, the space must be thoroughly vented and the atmosphere tested prior to entry.

PPE must be used as appropriate and kept dry at all times when handling sulphur or using equipment used for handling sulphur.
