Nations across the world are adopting the UN advocated Global Harmonized System of classification and labeling of substances with the objective of achieving a number of goals. One objective is a protection of the health of staff engaged in the series of handling, storage, processing, and transportation of these chemicals. Another is to protect the environment. A central system of classification will facilitate trade between different countries and accurately identify chemicals and their hazard levels.
Some states did not have in place a classification system while some who did had different procedures of categorization and classification that caused confusion and insecure scenarios. Development of these GHS safety data sheets was based on an extensive study that sought to deal with disparities and result in uniformity when ensuring that degree of protection did not reduce.
The classification procedure takes into consideration the basic hazardous properties of their formula and compounds as well as reactivity with water, air and other chemicals besides impact that the when discharged into the surroundings. GHS SDS have been developed in a structured manner with each segment being taken care of by those in the chain from the processing to the end users. Through time GHS underwent revisions and nations accepted them besides presenting their own standards.
One of the characteristics of the SDS is that disclosure of hazard must be made but without compromising personal data of the formulations. A vital characteristic is that of training workers in the use of SDS and suitable procedures in regard to the substances they handle and this training comprised interpretation of the safety data sheets and the safety stickers. The way of application of hazard communication part varies based on the point in its usage cycle and product class.
There are anomalies and exceptions that those working with the hazardous chemicals need to know. GHS does not specify a test method that is uniform but depends on evaluations conducted by test bureaus or relies on WHO data in relation to health and environmental hazards. In the case of physical hazards like flammability and volatile, an individual may refer to UNSCETDG tests. GHS relies on data that was available but as new info is discovered the method of classification could change, and manufacturers or providers must keep abreast of these changes. Some substances may not have to get labeled, and such exceptions apply to pesticides, rodenticide and fungicides or compounds that are in the special Acts.
GHS is effective in bringing in uniformity in categorization and classification of compounds but it is very complicated with anomalies and exceptions. It requires GHS SDS and to be prepared by experts and tags that are compliant take care of protecting branded formulations while handling exceptions and anomalies.
