Abstract: The aim of this study is to examine the underlying principles of international labour standards relating in Malaysian occupational health. Researcher will first examine the ILO standards on occupational health and will subsequently discuss the position of the same subject under Malaysian law. It must be said from the outset that this study will not attempt a discussion on a strict comparative approach but rather to examine the impact that the ILO standards has on Malaysian law on this issue. The main concern is whether Malaysian law on occupational health is at par with the ILO standards or has lagged far behind. The discussion of this study is centred on a theme that the legal regime of occupational health either at the international or national level can be viewed from the preventive or rehabilitative perspective. The law is said to be preventive if it is aimed at avoiding the risk or hazard or accident from taking place or happening and it is rehabilitative if it is to compensate the victims.
