SULPHUR UN NO 1350 / CLASS 4.1

Class 4.1 flammable solids, such as sulfur (UN generic entry No.1350), should not be taken lightly. These solids are readily combustible and can cause fire, posing significant risks in shipping.

Yellow in colour, sulphur's contact with chlorates, nitrates, perchlorates, and permanganates leads to the risk of explosion.

Sulphur is not soluble in water, there is the danger of fire when in contact with oil and fat,

The sulphurous smell can affect pieces of goods, potatoes, and other consumption articles.

??????????? When involved in a fire, toxic, irritating, and suffocating gas evolves.

??????????? The dust forms an explosive mixture with air, which may be ignited by static electricity.

??????????? Forms explosive mixtures with oxidizing substances.

??????????? Corrosive to steel, in particular in the presence of moisture.

?Sulphur is a relatively cheap commodity used in the manufacture of fertilizer.

It is a byproduct of the petrochemical industry and is also found in its natural form.

After processing, it is often shipped in pellet form.

Did you know that:

Sulphur is the 10th most abundant element in the Milky Way Galaxy.

It's a cosmic element found not just on Earth but also in its crust, ocean, and even meteorites, a fact that never fails to astound.

Did you know that Sulphur is a versatile element? 55 % of it is used to produce fertilizers, contributing to agricultural productivity.

The remaining 45 % produces a wide range of commercial products, showcasing its adaptability.

Sulphur is found in onions, eggs, cauliflower, and soybean flour.

Sulphur is found in humans, chickens, and sheep.

With its unique properties, Sulphur has been a part of human history for centuries.

It's used in matches and fireworks because it burns easily.

Its ancient name, "brimstone", means "the stone that burns", a testament to its enduring significance.

The challenges come when you have to deal with SULPHUR as a NON-DG as per IMDG code:

IMDG Special Provision (242): Sulphur is not subject to the provisions of this Code when it has been formed to a specific shape (such as prills, granules, pellets, pastilles or flakes).

Some shippers misuse the special provision intentionally or not and provide documents proving that cargo complies with SP 242 and the Non-DG letter from the POL Competent Authority.

But still, the question is, have the shippers provided documents related to the cargo that will be stuffed inside the container?

The photos below were taken during a container inspection reported by the EHS department while attending a hot work/welding for repair at one of the transit ports.

This case could lead to a fire disaster if the welding spark heat were extended to the cargo inside the container.

1. SULPHER was wrongly declared as Non-DG based on the shape provided in the MSDS & shipper letter.
2. We can see that there is no proper cargo securing as per CTU.>> IMDG 5.4.2.1.4 >>

"Drums have been stowed in an upright position unless otherwise authorized by the competent authority, and all goods have been properly loaded and, where necessary, adequately braced with securing material to suit the mode(s)? of transport for the intended journey;"

?CTU Code means the IMO/ILO/UNECE Code of Practice for Packing of Cargo Transport Units (MSC.1/Circ.1497).

3. Improper packages were used, and cargo powder fell everywhere outside the package, which could lead to fire if the required circumstances were in place.

?Safety is not just the responsibility of a few; it's everyone's duty.
