What is GHS? - ANSWER-Globally Harmonized System
GHS - ANSWER-Is an international initiative to standardize chemical hazard classification and
communication globally
-helps harmonize hazard communication systems worldwide and provides set of guidelines for ensuring
the safe production, transport, handling, use and disposal of hazardous materials
,Whmis is a national hazard communication system that - ANSWER-Provides information on the safe use
of hazardous materials in Canadian workplaces GHS doesn't replace WHMIS
WHMIS Will be modified to incorporate the GHS elements with standardized - ANSWER-Chemical
classification rules
Label requirements
Safety data sheets (SDS) format (formally MSDS)
The GHS has more detailed and comprehensive criteria which results in expanded hazard categories and
improved communication of hazards to workers. The resulting harmonization is expected to -
ANSWERMaintain/enhance worker protection while reducing barriers to trade among countries
The GHS consists of two subcommittees: the subcommittee of experts on the transportation of
dangerous goods and the subcommittee of experts on the globally harmonized. These subcommittees
handle the technical aspects of the GHS and ensure that: - ANSWER--hazard classification is based on
intrinsic properties of the substances and mixtures
-all types of chemicals covered
-all stakeholders are involved
What is the GHS expected to do - ANSWER-Identify hazards found in substances and mixtures and
communicate hazard information about these hazards. To achieve this the criteria for hazard
classification or match to the hazard statements, symbols, and signal words have been standardize to
form an integrated hazard communication system
Integrated hazard communication system by the GHS - ANSWER--GHS labels are the main
communication tool for consumers
-GHS is similar to existing transport requirements where containers will be marked with pictograms that
address acute toxicity, physical hazards, and environmental hazards. However, signal words in hazard
statements requirement haven't been adopted by the transportation sector
-all GHS elements are to be adopted in the workplaces, including harmonized labels, safety data sheets,
and employee training
, Well WHMIS 2015 includesNew harmonize criteria for hazard classification and requirements for labels

hazardous products act. New hazardous products regulation HPR is now enforced
Federal changes include - ANSWER--hazardous products act has been amended
-New hazardous products regulation has been established
-former parts of legislation such as controlled products regulation, hazardous materials information
review act and ingredient disclosure list have a need revoked
Provincial changes include - ANSWER--Amended occupational health and safety act -amended
Ontario WHMIS regulation 860
From 2015 to 2018 a transition period from old WHMIS to WHMIS 2015 GHS took place - ANSWER-The
2015 legislation is currently in force which means that suppliers may begin to use and follow the new
requirements for label and safety data sheets for hazardous product sold, distributed, or imported into
Canada
As with the old WHMI ass the WHMIS 2015 have a three key ways in which information on hazardous
materials is communicated. The supplier of the hazardous material provides the labels and safety data
sheets to the employer. The employer passes the information on to the worker and provides education
programs
LABELS: - ANSWER-Labels under WHMIS 2015 have a few new requirements however the main principle
of the label remains the same as it is under old WHMIS to alert workers to the hazards of the materials
within
