What is GHS?What is GHS?
GHS is the abbreviation for Globally Harmonized System of Classification
and Labelling of Chemicals. It is developed by the United Nations to classify
chemicals by types of hazard and proposes harmonized hazard
communication elements, including labels and safety data sheets, to
enhance the protection of human health and the environment during the
handling, transport and use of these chemicals.
The GHS also provides a basis for harmonization of rules and regulations
on chemicals at national, regional and worldwide level, an important factor
also for trade facilitation.

Benefits of GHSBenefits of GHS
Enhance the protection of human health and the
environment by providing an internationally comprehensive
system for hazard communication;
Provide a recognized framework for those countries
without an existing system;
Reduce the need for testing and evaluation of chemicals;
Facilitate international trade in chemicals by having thei r
hazards properly identified and assessed on an
international basis.

Classification of HazardsClassification of Hazards
Hazard ClassificationHazard Classification
GHS classifies chemicals into three main classes: Physical Hazards,
Health Hazards and Environmental Hazards.
Each hazard class is divided into different sub-classes based on the
intrinsic hazardous properties of the chemicals.
Each hazard sub-class is further divided into hazard categories
depending on the severity of the hazard. A lower category number
indicates a more hazardous nature of the chemical and vice versa..
Each hazard class or category is known as a building block in GHS.

FindingsFindings
Problems with SDS
Uncommon synonym for PCE was stated. Literature shows that tertracap is a
synonym of tetrachloroethylene or perchloroethylene (PCE).
Permissible exposure levels provided are inaccurate
Declared ingredients were not found in the chemical, Trisoh 101
PCE is not safer than TCE. Both are Chlorinated hydrocarbons
CNS impairment
Toxic effects on the liver & kidneys if exposure is excessive. Possible
carcinogens to human beings.
Persons exposed to TCE or PCE are required to undergo regular medical
examinations.
Investigations showed that both Unigold & Shinei were deceived by Best
Chemical into believing that Trisoh 101 is a safer substitute for TCE.
