10 Sodium Hydroxide Solution SDS: Understanding the Safety Data Sheet
Sodium hydroxide (NaOH) is a highly caustic and corrosive substance commonly used in various industries, including manufacturing, cleaning, and wastewater treatment. When handled improperly, it can pose serious health and environmental risks. Therefore, it's essential to understand the Safety Data Sheet (SDS) for a 10 sodium hydroxide solution.
What is an SDS?
A Safety Data Sheet (SDS) is a document that provides information on the safe handling, use, storage, and disposal of a hazardous substance. It is an essential tool for workers, emergency responders, and others who may be exposed to the substance.
