Little Pro on 2016-01-04

GHS has been introduced to Malaysia via CLASS Regulations issued in Oct 2013 and the Industry Code of Practice on Chemicals Classification and Hazard Communication(ICOP) issued on 16 April 2014. Industry has been given one year grace period to comply with CLASS Regulations and ICOP since ICOP was published.

ICOP is promulgated as a guidance to help the industry comply with CLASS Regulations. It sets out detailed requirements on chemical classifications, labelling and safety data sheets (SDS).

ICOP consists of four parts:

  • Part I: List of Classified Chemicals
  • Part II: Chemicals Classification
  • Part III: Hazard Communication: Labelling and Safety Data Sheet
  • Part IV: Confidential Business Information
