What are two main components included in Hazard Identification of an MSDS?

The identification of hazards in a Material Safety Data Sheet (MSDS) is crucial for ensuring safety when handling chemicals. The correct choice highlights the importance of carcinogenic properties and exposure limits. Carcinogenic properties indicate whether a substance can potentially cause cancer, which is vital information for assessing long-term health risks associated with exposure. Exposure limits provide guidelines on how much of a substance can be safely inhaled or absorbed without adverse effects, allowing individuals to work safely with those materials. This information is essential for implementing appropriate safety measures in the workplace.

The other choices provide relevant information but do not directly pertain to the core components of hazard identification in an MSDS. First aid measures and toxicological information, while important for understanding the effects of exposure, do not specifically focus on hazard identification. Similarly, handling and storage instructions and disposal considerations are crucial for safe usage but are more about management of the substance rather than identifying its hazards. Lastly, chemical composition and physical properties pertain to the characteristics of the substance but do not explicitly indicate the associated hazards.
