Which of the following is a potential hazard of sodium borohydride according to the SDS?

Sodium borohydride is recognized for its chemical reactivity, particularly its interaction with water. When sodium borohydride comes into contact with water, it can release hydrogen gas, which is flammable and poses an explosion risk in certain conditions. This reaction is significant enough to be highlighted in the Safety Data Sheet (SDS) as a potential hazard.

Understanding this hazard is crucial for handling sodium borohydride safely in the lab. The correct answer reflects the importance of being aware of the violent reactions that certain chemicals can undergo when they interact with water, and it underscores the need for appropriate safety measures when using such reagents. Other options that suggest non-toxicity, safety for skin contact, or only being hazardous when heated do not accurately represent the key risks associated with sodium borohydride as outlined in the SDS.
