How Many Types Of Cleaning Are Done Depending On The Cargo?

Clean cargoes such as Soda Ash or Mineral Sands could potentially be damaged by any form of contamination. These normally require the compartments to be ‘hospital clean’ before loading.

Cargoes such as grains, fertilisers and cement are normally deemed ‘moderately clean to moderately dirty cargoes’ and typically require the hold to be at a ‘grain clean’ standard of cleanliness.

Dirty cargoes such as Bauxite or some types of coal are unlikely to be contaminated by any small amounts of rust or paint from the steel structures within the holds, although it is very important to check the exact cleanliness requirement.

What Is A ‘Hospital Clean Standard of Cleanliness?

For a ‘hospital clean’ standard of cleanliness, there should be no rust, no loose rust, no loose paint flakes and no previous cargo residues. This strict cleanliness is usually only achievable by vessels that only trade clean cargoes.

What Is A ‘Grain Clean’ Standard of Cleanliness?

A stowage area must comply with the standards of fitness established herein to be considered clean; dry free of infestation, rodents, toxic substances and foreign odours.

Rust And Paint Scale

A stowage area must not contain more than 25 square feet of loose rust scale or paint scale in a single area or more than 100 square feet of loose rust scale or paint scale in aggregate. Generally hard adhering rust is acceptable for a ‘grain clean’ standard.
