The distinctiveness of potash inspection is that this chemical product is classified as fire and explosion hazardous and belongs to the 3rd hazard class in terms of the degree of impact on the human body. Therefore , work with potash should be carried out in special clothing (protective suit, mask, oil-resistant gloves and special footwear). In order to safely store potassium carbonate, closed dry rooms are used. Since potash is highly hygroscopic, it is important to store it in a moisture-proof environment. It is a chlorine-free fertilizer. It is used in greenhouses for growing vegetables. The grown vegetables are considered than environmentally friendly.

Incoming/outgoing potash inspection.

It is carried out during delivery of potash to silos or to a port, or at releasing it from factory/silo warehouses. The CISS GROUP inspector will visually assess the condition of the premises for the suitability for cargo storage; will check the cargo itself so that it is dry, not mixed with other cargo, not damp or wet, free from pests, foreign matter, weeds, mold or foreign odors. If potash is delivered in bags, the inspector will inspect them for traces of soaking, and if agreed, will perform the selected bag opening for sampling purpose and further visual check of cargo quality.

Acceptance of cleanliness containers / holds of vessels before loading potash.

This is a visual inspection of containers and empty holds for their cleanliness and suitability for potash transportation. The inspector carefully examines their internal surfaces, checks the integrity and condition of locks, hinges and other fasteners on the container doors, rubber seals for container doors and hold covers.

Visual control of the loading process and sampling of potash.

During loading, the inspector controls the loading of potash, confirms the gross / net weight during re-weighing; in the case of loading potash into the holds - the initial, intermediate and final check of the weight of the loaded cargo by the draft survey method, controls the fumigation process; conducts a visual assessment of the quality of the cargo, takes samples in accordance with sampling rules, forms composite samples. At the end of the loading, the inspector will seal the loaded containers or holds. He enters all the data into reports to which the client gets direct access. Note that the CISS GROUP loading inspection and sampling can be carried out around the clock on 24/7 basis.

Laboratory analyzes of potash quality.

The determined standard indicators of potash quality include: appearance, mass fraction of potassium carbonate, mass fraction of sodium carbonate, mass fraction of potassium hydroxide, mass fraction of iron, mass fraction of heavy metals, mass fraction of water-insoluble residue.

Photo and video report.

The inspector records each stage of the inspection with photos and videos. All such data contain the date and time of recorded stage of inspection. At the end of the potash inspection, CISS GROUP provides a detailed photo report of all stages of control and inspection.
