SDS sections: How many sections does an SDS typically have, and what is the purpose of Section 2?

• A. 20 sections; includes supplier logos
• B. 12 sections; lists shipping information
• C. 16 sections; describes hazards and signal words
• D. 8 sections; provides disposal methods

Answer: (C)

Safety Data Sheets use a standardized 16-section format, so you can quickly find the same information every time. Section 2 is hazards identification. It describes the hazards of the chemical and how they are classified, and it provides the signal word (such as Danger or Warning), hazard statements, precautionary statements, and any pictograms. This section tells you the level and type of risk and helps you decide what protective measures to use and what actions to take in an emergency. The other options misstate either the number of sections or what Section 2 contains—for example, shipping/transport details belong in transport information, and disposal methods are in the disposal considerations.
