Foreword This Singapore Standard was prepared by the Working Group appointed by the Technical Committee for Chemistry under the direction of the Chemical Standards Committee. This standard is a revision of CP 100 : 2004 and has been re-numbered as SS 603 : 2014. The revision includes updates on technology, process, and regulatory agencies in Singapore involved in hazardous waste management. Safe handling and proper disposal of hazardous wastes are essential elements of a total environmental management programme. Mismanagement of hazardous wastes can cause safety, health and environmental damage including the following: (a) Contamination of water resources and watercourses; (b) Pollution of the air; (c) Fires and/or explosions; (d) Poisoning of humans and animals via the food chain; (e) Poisoning of humans and animals via direct contact.

In Singapore, a comprehensive, regulated programme has been in place since 1987 to control the generation, collection, transportation, storage, treatment and disposal of hazardous or toxic industrial wastes. Over the years, industries have recognised proper management and handling of hazardous wastes as an integral part of their manufacturing processes and plant operations. Under the Environmental Public Health (Toxic Industrial Waste) Regulations, specific types of hazardous wastes generated from industries are listed in the Schedule of the Regulations for control of toxic industrial wastes. The Regulations control the generation, collection, transportation, storage, treatment (which includes recycling and recovery) and disposal of the listed toxic industrial wastes. The import, export and transit of hazardous wastes are controlled under the Hazardous Waste (Control of Import, Export and Transit) Act and its Regulations. This Act and its Regulations serve to implement the requirements of the Basel Convention on the Control of Transboundary Movements of Hazardous Wastes and their Disposal. Under the Basel Convention, hazardous wastes are defined as wastes generated from industrial processes or wastes having the hazard characteristics listed in the Annex of the Convention. In preparing this code, reference was made to the following publications: 1. ANSI Z400.1/ANSI Z129.1 : 2010 Hazardous evaluation and safety data sheet and precautionary

labeling preparation

2. NFPA 49 Hazardous chemicals data (2010) 3. Code of practice on packaging, labelling and storage of chemical wastes (Hong Kong - 2012)

4. The Basel Convention on the “Control of Transboundary Movements of Hazardous Wastes and

their Disposal”, adopted by the Conference of the Plenipotentiaries on 22 March 1989 and entered into force on 5 May 1992

5. SS 593 : 2013 Code of practice for pollution control 6. Code of practice on workplace safety and health (WSH) risk management (WSHC - 2012)
