It also contains hazard pictograms or danger symbols which gives you a quick indication of the hazards associated with the chemical.
Safety Data Sheet A Safety Data Sheet (SDS), previously called a Material Safety Data Sheet (MSDS), is a document that provides information on the properties of hazardous chemicals and how they affect health and safety in the workplace. For example an SDS includes information on:
- the identity of the chemical,
- health and physicochemical hazards,
- safe handling and storage procedures,
- emergency procedures, and
- disposal considerations.
- Safety data sheets must contain the following headings:
- Identification of the substance/preparation and of the company/ undertaking (must be identical to that on the label.
- Composition/ information on ingredients’ chemical names.
- Hazards identification (a summary of the most important features including adverse health effects).
- First aid measures.
- Fire-fighting measures.
- Accidental release measures-covering safety, environmental protection and clean up.
Other information to be included are Handling and storage-recommendation for best practice especially storage conditions and incompatible materials; Exposure controls/ personal protection-any specific recommendations and PPE; physical and chemical properties-stability, physical and solubility properties; stability and reactivity- conditions and materials to avoid; toxicological information-acute and chronic effect, routes of exposure and symptoms.
The following must also be included: Ecological information-environmental fate of the chemical and its effect; disposal consideration-specific dangers; transport information-special precautions; regulatory information-overall classification of the product and any specific legislation that may be applicable; and Other information – information not captured in the preceding sections like explanations of abbreviations used etc.
Hazard Pictograms . A hazard pictogram is an image on a label that includes a warning symbol and specific colours intended to provide information about the damage a particular substance or mixture can cause to our health or the environment.
