What are Material Safety Data Sheets (MSDS)?
Material Safety Data Sheets (MSDS), also known as Safety Data Sheets (SDS), are essential documents that provide detailed information about the properties, hazards, handling, storage, and disposal of chemical substances. In the context of histology, MSDS are critical for ensuring the safe use of various chemicals and reagents used in the preparation and examination of tissue samples.
Why are MSDS Important in Histology?
Histology laboratories frequently use a variety of chemicals, including fixatives, stains, and solvents. These substances can pose significant health and safety risks if not handled properly. MSDS provide crucial information to help laboratory personnel understand these risks and implement appropriate safety measures. This ensures a safe working environment, compliance with regulations, and the protection of both laboratory staff and the environment.
