Which of the following is NOT a typical symbol found on an MSDS?

Material Safety Data Sheets (MSDS), now known as Safety Data Sheets (SDS), are designed to communicate information about the properties of hazardous materials. They utilize a range of symbols to indicate specific hazards associated with chemicals.

The symbols for flammable, corrosive, and explosive substances are commonly included in an SDS. Each of these symbols conveys important safety information regarding how to handle and store these materials to minimize risks. For instance, the flammable symbol warns about the potential for a substance to ignite easily, while the corrosive symbol indicates that the substance can cause damage to living tissues or metals upon contact.

On the other hand, the radioactive symbol is not a typical representation found on an SDS. While radioactive materials do pose specific hazards, the regulatory frameworks for handling such materials often fall under distinct guidelines and supervision separate from those typically covered in an MSDS. Therefore, there are specialized documentation and labeling systems in place for radioactive substances rather than the SDS format applied to general chemical hazards. This distinction clarifies why the radioactive symbol is not included as a typical symbol on an MSDS.
