Material Safety Data Sheets The MSDS 29 CFR

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 Identification 2. Composition/Information on Ingredients 3. Hazards Identification 4. First Aid Measures 5. Fire Fighting Measures 6. Accidental Release Measures 7. Handling and Storage 8. Exposure Control/Personal Protection 9. Physical and Chemical Properties 10. Stability and Reactivity 11. Toxicological information 12. Ecological Information 13. Disposal Considerations 14. Transport Information 15. Regulatory Information 16. Other Information

Product and Company Identification Manufacturer’s name, address, phone number Emergency phone number Date of MSDS Name of the chemical Trade 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 effects Special instructions to physicians

Fire and Explosion Data Flashpoint Flammability limits in air Autoignition temperature Hazardous combustion products Extinguishing media to use and to avoid Firefighting protective equipment and instructions Unusual fire and explosion hazards

Accidental Release Measures Containment in spills Spill or leak clean up Evacuation procedures Special instructions Any reporting required for spills

Handling and Storage Storage requirements Dispensing requirements Handling requirements

Personal Protection Engineering controls (ventilation…) PPE needed for various routes of entry PPE needed in emergencies (spills, explosions) Personal hygiene/work practices PPE during repair/maintenance of equipment Other 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 materials Hazardous products produced during decomposition Stable or not Conditions to avoid

Special Sections Sections 1-10 are required on all MSDS’s Sections are not required by OSHA Most MSDS’s have all 16 sections Some have left blank

Toxicological Information Toxicity data Carcinogenicity Neurological effects Genetic effects Reproductive 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 shipping Proper shipping name/placard number Hazard class Does quantity being shipped change requirements

Regulatory Information Federal regulations (OSHA, FDA, USDA, DEA) State regulations International 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 = White Scale= 0 (no hazard) to 4 (extreme hazard)
