- BAssess and control exposure to hazardous substances to prevent ill health
- CProvide free private health insurance to all exposed workers

Why: A Safety Data Sheet (SDS) is a standardised 16-section document that provides comprehensive information about a chemical product. It includes hazard identification, composition, first aid measures, fire-fighting measures, accidental release measures, handling and storage, exposure controls and PPE, physical and chemical properties, toxicological information, and disposal considerations.
03Which GHS pictogram indicates a substance is toxic (acute toxicity)?
- AAn exclamation mark
- BA flame symbol

Why: The skull and crossbones pictogram (GHS06) indicates that a substance has acute toxicity and can cause death or serious harm through a single or short-term exposure via ingestion, inhalation, or skin contact. The flame indicates flammability, the exclamation mark indicates less severe hazards such as skin irritation, and the gas cylinder indicates gases under pressure.
