Endorsement of GHS by
• APEC Trade Ministers encouraged APEC members to work towards implementing the globally harmonized system (GHS) on hazard classification and labelling of chemicals and safety data sheets by 2006, including through capacity building.

Chemical Hazard Communication System
• A common and coherent approach
• To enhance the protection of human
health and the environment
• Facilitates international trade in chemicals,
whose hazards have been properly
assessed and identified on an international
basis

Part 1: Specification for Recommendation on the Transport & Storage of Dangerous Goods
Part 2: Globally Harmonised System of Classification & Labelling of Chemicals – Singapore’s Adaptations
SS 586:2014 Specification for Hazard Communication for hazardous chemicals and dangerous goods
Amendment No. 1 to SS 586 : 2008 Part 3 : Preparation of safety data sheets (SDS)
• SS 586 gazetted as an ACOP in the WSH (Approved Codes of
Practice) notification Feb 2011
Key consideration:-
• Recognize GHS pictograms : helpful for multi lingual employees
• Warned of the nature of hazards (ie hazard statements)
• Recognize the hazards involved and be familiar with the new 9 GHS pictograms
• Understand the contents of labels (Full GHS label / Wkplace reduced label)
• Know where to find the latest SDS in the workplace
• Understand SDS information in each section and its function
• Understand the precautionary measures to be taken , e.g. First aid, emergency response measures etc
• Use of suitable Personal Protective Equipment (PPE) and how to maintain PPE
• Provide training to all target audiences (workplace workers/contractors-transporters, fire fighters, emergency responders)
• Keep a record of training /refresher training e.g once every 3 years
