The conventional classification and labelling of chemicals are mostly found in a component of global harmonization system (GHS) known as safety data sheets (SDS). The system is extremely vital as it forms are conventional hazard classification criteria for chemical elements all around the world. GHS is a framework from which safety data sheets are derived and it helps to guide various manufacturers in labelling and classifying of hazardous chemicals with the purpose of protecting people and the environment. GHS details the classification and communication of hazardous chemicals that forms a conventional mode which can be applied in various places in the world. The importance of GHS is that it helps in the forming of unconventional way of classifying and labelling of hazardous chemicals in the communication thereof as various countries would come up with various standards for the many kinds of chemicals that exist and this would be rather confusing for manufacturers.
In general, safety data sheets serve the purpose of providing information concerning the various kinds of chemicals in the hazardous effects, including the environmental consequences, which is able to guide manufacturers the safety precautions that they should undertake when they are using such chemicals. This therefore enables workers to develop strategic worker protection measures and the appropriate training that are specific to the workplace and also to put into consideration measures that will help them protect the environment better. You can find in safety data sheets information about poison centres, transport companies for hazardous chemicals, professionals who use pesticides, and emergency responders.
There are specific criteria to be formed for safety data sheets to be produced. They can only be production of safety data sheets when a manufacturer is able to have substances and mixtures that meet the harmonized criteria as per the stipulations in the GHS and this is in terms of the physical, health and environmental hazards of the chemicals which they possess. It also follows that safety data sheets should only be applied when the mixtures that a particular manufacturer holds have ingredients which are carcinogenic, harmful to reproduction and exceed the limits of SDS for toxic substances according to the criterion of mixtures. Some authorities will also require the production of safety data sheets when particular mixtures do not meet the criteria for the classification but contain hazardous components in some specific concentrations that can be detrimental to human health.
We can therefore justify that GHS safety data sheets are very important in the preservation of human life and the environment generally.
