Material Safety Data Sheets
The MSDS
29 CFR 1910.1200
Right to Know
You, the employee, have a right to know about the hazardous
chemicals you use on the job and how to work safely with
those chemicals.
The MSDS
Chemical manufacturers must determine a chemical’s hazards
and provide an MSDS.
The MSDS
Employers must: Make the MSDS available; Train employees on hazards of the
chemical; Train employees on how to protect
themselves.
The MSDS
Employees must: Read the MSDS; Be able to identify the hazards; Understand how to work safely
with the chemical.
MSDS Confusion
There is no standardized format for MSDS’s.
Where are Your MSDS’s
Binders, or Computer systems, or Both
?
Sections of an MSDS (No set order)
1. Product and Company Identification2. Composition/Information on Ingredients3. Hazards Identification4. First Aid Measures5. Fire Fighting Measures6. Accidental Release Measures7. Handling and Storage8. Exposure Control/Personal Protection9. Physical and Chemical Properties10. Stability and Reactivity11. Toxicological information12. Ecological Information13. Disposal Considerations14. Transport Information15. Regulatory Information16. Other Information
Product and Company IdentificationManufacturer’s name, address,
phone numberEmergency phone number Date of MSDS Name of the chemicalTrade names and synonyms
Composition/Ingredients
Hazardous Ingredients Exposure limits of hazardous ingredients Hazardous chemical names Percentage of chemical in the product Nonhazardous ingredients Trade secrets Exposure Limits PEL (Permissible Exposure Limit)
STEL (Short Term Exposure Limit) TLV (Threshold Limit Value)
Hazards Identification
Emergency overview Routes of entry (eye, skin, inhalation, ingestion) Signs and symptoms of exposure Single, repeated or lifetime exposure Mild, moderate or severe exposure Acute or chronic effects Target organs Medical conditions that may be aggravated by exposure Carcinogenicity Potential environmental effects
First Aid Measures
First aid treatment by route of entry to body
Immediate medical attention needed
Any delayed effectsSpecial instructions to physicians
Fire and Explosion Data
FlashpointFlammability limits in airAutoignition temperature Hazardous combustion products Extinguishing media to use and to avoidFirefighting protective equipment and
instructionsUnusual fire and explosion hazards
Accidental Release MeasuresContainment in spillsSpill or leak clean upEvacuation proceduresSpecial instructionsAny reporting required for spills
Handling and Storage
Storage requirements Dispensing requirements Handling requirements
Personal ProtectionEngineering controls (ventilation…)PPE needed for various routes of entryPPE needed in emergencies (spills,
explosions)Personal hygiene/work practicesPPE during repair/maintenance of equipmentOther special PPE considerations
Physical and Chemical Properties Physical appearance Odor Liquid, solid or gas Boiling point, melting point, freezing point Specific gravity Soluble in water pH Vapor Density
Stability and Reactivity
Incompatibility with what materialsHazardous products produced
during decompositionStable or notConditions to avoid
Special Sections
Sections 1-10 are required on all MSDS’s
Sections 11-16 are not required by OSHA
Most MSDS’s have all 16 sectionsSome have 11-16 left blank
Toxicological Information
Toxicity dataCarcinogenicityNeurological effectsGenetic effectsReproductive effects
Ecological Information
Environmental hazard statements
Disposal Considerations
Any regulations pertaining to disposal
Physical/chemical properties affecting disposal
State or local requirements that may apply
Transport Information
Regulated during shippingProper shipping name/placard
numberHazard classDoes quantity being shipped
change requirements
Regulatory Information
Federal regulations (OSHA, FDA, USDA, DEA)
State regulationsInternational considerations

Other Information
Special label text Hazard rating systems Special considerations not otherwise mentioned NFPA and HMIS Information
1. Health = Blue 2. Flammability = Red 3. Reactivity = Yellow 4. Other hazards or special handling = WhiteScale= 0 (no hazard) to 4 (extreme hazard)
SummaryMSDS is the foundation of chemical safety 24-hour access Symptoms of exposure First aid Storage Handling Personal protective equipment
