What is a potential effect of sodium borohydride on skin?

Sodium borohydride is a reducing agent commonly used in organic chemistry, particularly for reducing carbonyl compounds. When it comes to its effects on skin, it is important to accurately understand its reactivity and potential hazards.

The correct understanding highlights that sodium borohydride can cause skin irritation due to its alkaline nature and the potential for chemical reactions upon contact with moisture, including sweat on the skin. Such interactions can lead to discomfort or irritation but typically do not result in severe skin burns under normal exposure conditions. Severe burns are more commonly associated with stronger corrosives such as strong acids or bases.

Although prolonged contact with sodium borohydride can increase the likelihood of irritation, stating that it causes severe burns does not accurately reflect its typical interactions with skin tissues. Therefore, recognizing that sodium borohydride may cause minor irritation is the most appropriate conclusion regarding its potential effects on skin.
