Storage of Dangerous Goods and Chemical Warehousing in Malaysia: What You Should Know About

Chemical warehousing in Malaysia is the storage of Dangerous Goods (DG) which is regulated under the . The storage of hazardous goods is regulated with strict compliance with protocols, safe practices, and paperwork to ensure compliance and safety. 


Some of the dangers associated with chemical warehousing include fires, explosions, and harmful fumes. In order to prevent these accidents, chemical warehouses must have proper ventilation, fire suppression systems, and emergency exits. Other safety measures include trained staff and regular safety inspections.


Types of hazardous materials. 


Under the Storage of Hazardous  Chemical Guideline guidelines by the Department of Occupational Safety and Health under the Ministry of Human Resources Malaysia, There are ten hazard categories, which comprise five hazard categories based on physicochemical properties.


1.Explosive chemicals 


These are chemicals that may explode under the effect of flame and are sensitive to shocks and frictions. 


2. Oxidizing chemicals 


These chemicals give rise to the highly exothermic ( chemical process of releasing heat quickly)  reaction when in contact with other chemicals, remarkably flammable chemicals. For example, sodium chlorate should not be store on wooden pallets or close to combustible chemicals.  Oxidizing chemicals should be isolated from organic materials, flammable liquids, corrosives, toxicants, heat, and intense sunlight.


3. Flammable Materials 


Under The Occupational Safety & Health (Classification, Packaging, and Labelling of Hazardous Chemicals) Regulations 1997, flammable chemicals are classified into three sub-categories, i.e., Extremely Flammable, Highly Flammable, and Flammable, which could come in the form of liquids, solids, and gases.


4. Toxic Chemicals 


Toxic chemicals can be harmful by contact, inhalation, and ingestion and avoided from contact with heat, acids, moisture, and oxidizing chemicals. Toxic chemicals stored should be in ventilated storage areas in unbreakable secondary containers. Chemicals with high chronic toxicity, such as mutagen, teratogens, and carcinogens, should be identified with a label.


5. Corrosive Materials


Corrosive Chemicals include strong acids, alkalis that will cause burns or irritation of the skin, eyes, or most materials. Corrosive chemicals include hydrofluoric acid, hydrochloric acid, sulphuric acid, nitric acid, and perchloric acid. Such material may cause damage their containers and leak into the atmosphere of the storage area; some are volatile, and others react violently with moisture, organic matter, or other incompatible chemicals.

Can any warehouse handle hazardous materials? 


No, A warehouse must be certified to perform chemical storage.  The certification process is rigorous and can involve government and local council agencies, the fire department, and the Department of Environment; each may involve lengthy processes. 


What to look out for in a chemical warehouse rental facility 


When a company rents a warehouse that stores dangerous goods materials, it is essential to know that all warehouses are unequal. Opting to rent the wrong warehouse can endanger your safety of products and people. The wrong choice could negatively impact your finances and warehouse operations, as audit violations can result in hefty fines that disrupt warehouse operations.




Ensure that the warehouse has the licenses, permits, and certification.


A good way is to have an audit list during the vetting process. You can ask for starters to see business licenses, fire department operating permits, fire safety certificates,  certification of completion and compliance, and other applicable registrations. A proper dangerous goods warehouse facility should provide past hazard Identification and chemical safety data sheets,  classification and labeling, and a chemical register of the stored chemicals. 




The warehouse has the necessary fire safety facilities material safety records .


If the warehouse has undergone recent audits, you'll want past information on chemical safety data sheets (CSDS) related to materials handling and fire safety audits. A typical good warehouse should have firewalls, ESFR or early suppression, fast response sprinklers, smoke extraction systems or proper ventilation systems, fire doors, and first aid facilities. 


Check the surrounding warehouses' storage area. 


Chemicals proper storage areas should be located away from densely populated areas, from drinking water sources, areas liable to flooding, and flooding and external sources of hazards. The warehouse should be in an industrial land or industrial zone warehouse controlled by the planning legislation. The location should provide easy access for transport and hospital buildings. Adequate services should be provided, including electricity with emergency supply if needed, hydrant and fire-fighting water, and drainage preventing ground run-off to either public/storm sewer or a waste treatment plant as a part of a site containment plan.
