ES&H Manual



6610 Appendix T1

Material Safety Data Sheets (MSDSs)



Jefferson Lab has determined that working with chemicals carries an unmitigated Risk Code >2.  At a minimum all tasks requiring chemicals are discussed with the supervisor prior to commencement of work.  An Operational Safety Procedure (OSP) is written for work considered to be Risk Code >2 in accordance with ES&H Manual Chapter 3210 Work Planning, Control, and Authorization Process.


1.0            Purpose


Jefferson Lab recognizes that material safety data sheets (MSDS) are a key source of hazard information and requires that they be available to everybody at Jefferson Lab.  This appendix describes the information generally available on a MSDS and provides the instructions on how they are obtained, accessed, and filed.


2.0            Scope


Information is never to be changed or added to a MSDS by anyone other than the manufacturer.  Contact the MSDS Coordinator for clarification, or to check the accuracy of a document.  Upon receipt of a chemical’s MSDS a copy is submitted to the MSDS Coordinator to ensure its accuracy and for filing.


This appendix applies to Jefferson Lab’s chemical MSDSs and is performed in coordination with ES&H Manual Chapter 6610 Chemical Hygiene Program. 


3.0            Responsibilities


Overall program responsibilities are outlined in ES&H Manual Chapter 6610 Chemical Hygiene Program.


4.0            Objectives


4.1              Standard Content Information

Typically MSDSs contain the following information:

·         Name, address, and telephone number of the chemical manufacturer;

·         Physical and chemical characteristics;

·         Date of preparation;

·         Ingredients in concentrations of 1% or more (for carcinogens, the concentration is >0.5%);

·         Associated health hazards including:

o   Occupational Safety and Health Administration (OSHA) permissible exposure limits (PEL) and/or ACGIH TLV;

o   Primary routes of entry;

o   Carcinogen potential;

·         Safe handling and storage methods;

·         Recommended engineering controls and PPE;

·         Emergency/first aid procedures; and

·         Environmental impacts.


4.2              MSDS Access

MSDSs are available to everyone at Jefferson Lab through the on-line MSDS Database, which is searchable by:

·       Chemical/trade name

·       Building and room/work area


If the MSDS is not available in the database:

·         Contact the chemical manufacturer and make a request.

·         Go on-line to the chemical manufacturer’s website and print the document.

·         Receive the MSDS with chemical packaging at delivery to Jefferson Lab.  

·         Ask the MSDS Coordinator for a paper copy.


4.3              Subcontractor’s MSDSs

Subcontractors using chemicals in areas where Jefferson Lab employees have potential to be exposed are required to submit a copy of their MSDSs to the MSDS Coordinator through their SOTR.


Where no Jefferson Lab employees have potential exposure subcontractors are required to maintain MSDSs in a central location on the job site.
