MSDS Sheets, also called Material Safety Data Sheets, are official safety documents required by OSHA. These sheets explain how to safely handle, store, and work with substances in the workplace that may be hazardous.
They also serve as an information source for anyone who needs to know what chemicals or materials are present at a facility. OSHA requires that these documents be available for workers to review at any time. Copies must also be shared with local fire departments, which helps with spill response and emergency planning.
Purpose of MSDS Sheets
The main purpose of these safety documents is to reduce workplace risks by making hazard information easy to understand and easy to access. When workers know what substances they are working with, they can take the right precautions and avoid injuries or health problems.
These documents support safe operations and help companies remain compliant with OSHA regulations.
Where MSDS Sheets Are Kept
Most workplaces store these documents in:
- Clearly labeled binders
- Wall-mounted holders
- Central safety stations
They must be placed in areas where workers can access them quickly without needing approval or supervision.

What Information Is Included
Each sheet focuses on one substance and typically includes:
- Safe handling and storage instructions
- Health and exposure warnings
- Required protective equipment
- Emergency and spill response steps
- Fire and reactivity risks
The information helps workers understand potential dangers before working with the material.
Common Substances Listed
Most worksites use materials that require disclosure, such as:
- Cleaning agents
- Industrial chemicals
- Manufacturing compounds
- Fuels and petroleum products
- Maintenance and repair chemicals
Even routine materials may need documentation if they present a safety or health risk.
Why OSHA Compliance Matters
OSHA requires safety documentation to protect workers and emergency responders. Missing or inaccessible safety sheets can lead to:
- Increased risk of injury
- Poor emergency response
- Regulatory violations
- Costly fines and penalties
Having proper documentation in place is a key part of any workplace safety program.
They are safety documents that explain how to safely handle hazardous substances in the workplace.
Yes, OSHA mandates that they be available wherever hazardous materials are present.
All workers, supervisors, and emergency responders must be able to review them.
So they can safely respond to spills, fires, or chemical emergencies.
