Vast areas of the rainfed uplands in the humid and subhumid tropics currently used for traditional food crop production are dominated by these "fragile" soils. As the clay fraction of these soils are composed mainly of kaolinite, halloysite, and oxides of Fe and Al, the soil ECEC depends mainly on the soil organic matter level, which controls nutrient absorption and release. Significant changes in soil chemical and biological properties also occur following forest or bush fallow clearing and cropping.
For each chemicalthe chemical manufacturer or importer shall determine the hazard classes, and where appropriate, the category of each class that apply to the chemical being classified Chemical manufacturers, importers or employers classifying chemicals shall identify and consider the full range of available scientific literature and other evidence concerning the potential hazards.
There is no requirement to test the chemical to determine how to classify its hazards. Under the now-obsolete version of the standardthis process was far less rigorous and called hazard determination.
Hazard classifications replaced hazard determinations with the issuance of the current version of the standard. Classification lists the specific Classes of hazards, for example carcinogenicity or flammable solid.
Within the Hazard Classes the degree of hazard is indicated with a Category. The Category is usually a number or letter A, B, C although there are few that are indicated with words.
Some of the numeric categories have subcategories, so Class 2A is more hazardous than Class 2B, for example.
For gases and some reproductive toxinsthe categories are listed by names rather than numbers or letters. Further, as can be seen in the next section, not all hazard classes have entries ; some have only category 1, some haveorand Explosives is broken into 6 divisions!
We have no idea how a respected agency like the UN could come up with such a muddled and inconsistent ranking system.
How hard would that have been? Further Information In a hazard classification, only the intrinsic inherent hazardous properties of chemicals are considered. The three steps involved are: Identification of relevant data regarding the hazards of a chemical ; Subsequent review of those data to ascertain the hazards associated with the chemical ; Determination of whether the chemical will be classified as hazardous and the degree of hazard.
