Document Summary

The globally harmonized system (ghs) for hazard classification and labelling. Systems similar to whmis (for hazard communication) exist in other countries. In 1992, the united nations conference on environment and development (unced) agreed to develop a globally harmonized system (ghs) for hazard classification and labelling. It is anticipated that such a system will facilitate safe use of chemicals and reduce trade barriers. Roles of workers: suppliers: provide hazard information through labels and msds on all controlled products/containers of controlled products, employers (supervisors): ensure whmis labels, identifiers and msdss for all containers of controlled products. Confined space hazards arise due to oxygen deficiency. A causative agent is classified as hazardous in certain circumstances such as: high intensity. The mixture of gases extending from the earth"s surface. It is divided into several distinct layers (troposphere, stratosphere, etc. ), each separated by a region known as a pause (e. g. , the tropopause separates the troposphere and the stratosphere).
