The Globally Harmonized System of Classification and Labelling of Chemicals (GHS) is an international framework designed to ensure consistent communication of chemical hazards worldwide. Developed by the United Nations, the system standardises how chemical hazards are classified and how this information is conveyed to workers, consumers, and transport personnel.

• Universal hazard classification criteria.

• Clear and consistent labelling.

• Standardised 16-section Safety Data Sheets (SDSs).

• Helps meet regulatory compliance requirements globally.

For pesticide transport, TREM cards provide a quick-reference emergency guide for drivers, logistics personnel, and first responders. Because many pesticides are classified as dangerous goods, TREM cards summarize key transport-related risks.

TREM cards summarize key information such as:

• UN number and product classification.

• Hazard identification such as flammability, toxicity, or environmental danger.

• Required emergency actions in case of spills, leaks, fire, or exposure.

• First-aid measures and protective equipment needed on the vehicle.

• Special precautions for contaminated water runoff or soil exposure.

In the pesticide industry, SDS documents serve as the primary source of hazard communication for formulated products and active ingredients. They outline the product’s toxicological profile, environmental hazards, safe handling practices, required PPE, and emergency response actions. Because pesticide formulations often combine multiple active and inert components, SDS documents are essential to ensure workers understand the specific risks associated with mixing, storage, transport, and application.

SDS documents must be:

• Accessible to all employees handling pesticides.

• Kept up to date with the latest regulatory classifications (e.g., GHS, local legislation).

• Used to inform training, risk assessments, and emergency preparedness plans.

Act 15 of 1973, also known as the Hazardous Substances Act, regulates substances and products that may pose risks to human health or safety. The Act aims to prevent injury, illness, or death caused by hazardous materials.

• Control the importation, manufacture, sale, use, and disposal of hazardous substances.

• Regulate electronic products that may pose health or radiation risks.

• Classify hazardous substances into groups based on level of danger.

• Licensing of businesses dealing with hazardous substances.

• Regulation of production, disposal, and trade of substances.

• Inspection powers and enforcement mechanisms.

• Penalties for non-compliance.
