Which of the following is included in the physical and chemical properties section of an SDS?

The inclusion of the flash point in the physical and chemical properties section of a Safety Data Sheet (SDS) is critical because it provides essential information about the flammability of the substance. The flash point indicates the lowest temperature at which a substance can vaporize to form an ignitable mixture in air, making it a crucial factor in assessing fire hazards. Knowing the flash point helps in determining safe storage, handling, and emergency response measures for chemicals, especially those that are flammable or combustible.

The other options relate to different sections of the SDS. Routes of exposure typically fall under the health hazard section, focusing on how individuals might be exposed to the chemical. Carcinogenicity status also pertains to health hazards, detailing whether a substance is known or suspected to cause cancer. Hazardous reaction possibilities inform about reactivity and any dangerous reactions that might occur under certain conditions, usually categorized under stability and reactivity. These distinct sections of the SDS ensure comprehensive communication of relevant safety information for users handling the chemical.
