MATERIAL SAFETY DATA SHEET (MSDS)

MATERIAL SAFETY DATA SHEET (MSDS/SDS)

Material Safety Data Sheet (MSDS)—now more commonly known as Safety Data Sheets (SDS) under the Globally Harmonized System (GHS)—are indispensable tools for workplace safety and chemical management. Whether you’re a manufacturer, importer, distributor, or end-user, an SDS provides essential hazard, handling, and emergency information in a harmonized 16‑section format.

MSDSs originated in the 1980s as point-by-point lists, often varying significantly between manufacturers. The U.S. OSHA 2012 revision (HazCom 2012) aligned domestic sheets with GHS, mandating a standardized 16‑section SDS

  • Document details about critical information about chemical hazards, safe handling protocols, and emergency measures. Initially formulated under OSHA’s Hazard Communication Standard

What Exactly Is an MSDS/SDS?

An MSDS/SDS is a standardized document accompanying every hazardous chemical product. It provides detailed information about:
  • Product identification, manufacturer and emergency contacts
  • Hazard classification, signal words and pictograms
  • Ingredients, including CAS numbers and concentration
  • Safety procedures for handling, storage, and disposal
  • Emergency response measures such as first aid, fire-fighting, and accidental release procedures

Originally tailored to local regulations, MSDS formats varied widely by region. The GHS introduced a uniform 16‑section SDS structure to streamline communication and enhance consistency across international borders.

Purpose of MSDS/SDS

  1. Hazard Communication The core goal is to communicate chemical hazards—physical, health, and environmental—to anyone handling the substance. This includes workers, employers, emergency responders, and downstream users
  2. Regulatory Compliance OSHA, WHMIS (Canada), REACH/C&L (EU), and others mandate SDS: manufacturers and importers must develop them; distributors must pass them along; employers must make them readily available to employees
  3. Risk Management & Emergency Response SDSs guide chemical storage, handling, and disposal, with emergency procedures for spills, fires, and first‑aid—critical for risk prevention and incident management
  4. Training & Awareness As part of workplace safety programs, SDSs serve as foundational training materials. Employees must know how to locate, interpret, and apply SDS information

Contents of an MSDS/SDS

SDSs are structured into 16 sections, per GHS standards Identification – product name, synonyms, supplier info, intended use.
  1. Hazard(s) Identification – classification, signal words, pictograms, hazard statements
  2. Composition/Information on Ingredients – chemical identity, CAS numbers, concentrations
  3. First-Aid Measures – exposure symptoms and required medical interventions.
  4. Fire-Fighting Measures – suitable extinguishing media and precautions
  5. Accidental Release Measures – spill containment, cleanup, emergency PPE
  6. Handling and Storage – safe storage conditions, incompatibilities
  7. Exposure Controls/Personal Protection – occupational exposure limits, engineering controls, PPE
  8. Physical and Chemical Properties – appearance, odor, boiling point, etc.
  9. Stability and Reactivity – chemical stability, reactions, hazardous byproducts.
  10. Toxicological Information – routes of exposure, acute/chronic effects.
  11. Ecological Information – environmental impact, persistence
  12. Disposal Considerations – safe disposal methods, container handling
  13. Transport Information – UN numbers, hazard classes, packing
  14. Regulatory Information – local, regional, and international legal regulations.
  15. Other Information – preparation date, revision history, references.

In the U.S., OSHA focuses on sections 1–8 and 16, and defers sections 12–15 to other agencies, though the full 16-section format is still required
