Law requires all chemical manufacturers to determine the physical, health and other hazards of all chemical products that they market. Manufacturers must communicate this information to all purchasers in the form of an MSDS. The MSDS communicates the potential hazards of a chemical. MSDS are usually sent by the manufacturer with each chemical purchase. MSDS can be found at the following web sites:
Copies of all MSDS received from a manufacturer must be kept on file for 30 years. All persons engaged in University activities involving hazardous materials must have access to all applicable MSDS. The MSDS must be available for employees and students to review before beginning each chemical use activity. The MSDS must be the most recent version and easily accessible. Immediate access to hard copies of the MSDS must be made available in each work area in case of emergency situations.
OSHA specifies the information to be included on an MSDS but does not describe the precise format.
The main headings on a typical MSDS with appropriate information are as follows:
- Chemical Identity:
- The chemical and common name (s) must be provided for each chemical.
- The name of the manufacturer and their location is important.
Physical and Chemical Characteristics:
- Chemical and common names of all ingredients determined to be health hazards. Those comprising less than 1% (0.1% for carcinogens) of the mixture must be listed if they can still exceed an established Permissible Exposure LEL) or Threshold Limit Value (TLV) or present a physical hazard
Fire and Explosion Hazard Data:
- Examples are vapor density, vapor pressure, flash point, flammable limits, odor, boiling point, heat of combustion, and molecular or formula weight.
- The fire hazards of the chemical and the conditions under which it could ignite or explode must be identified. Fire fighting methods and the extinguishing agent of choice should be listed.
- Information should be provided on possible interaction with other chemicals.
Precautions for Safe Handling and Use:
- This section describes the nature of the hazardous affect resulting from exposure if no proper first aid is given. The primary routes of exposure such as inhalation, ingestion, skin, or eyes should be listed along with the affects, signs, and symptoms that could occur from acute and chronic exposure.
- This information is important in case the chemical is accidentally released or spilled. Precautions for safe handling and storage must be included, and the EPA waste disposal method is sometimes included in this section.
- Control measures are those taken to protect individuals from exposure. These include engineering controls, personal protective equipment, safe handling procedures, and special information necessary to prevent exposure.
- Often the disposal procedures provided on MSDS do not consider the regulatory requirements in place at a facility and should not be followed. Environmental Health Services should be contacted regarding disposal procedures.
MSDS are not required for biological/infectious agents or physical hazards encountered in the workplace. CSU-Pueblo Environmental Health & Safety will maintain copies of all MSDS's. A copy of any individual MSDS or questions can be obtained from Environmental Health Services or your Dean/Chair, Building Lab Coordinator. The chemical manufacturer or supplier will be contacted if additional information is required.
If you are working with chemicals or chemical products and would like to obtain a copy of the MSDS for your product please call EH & S at 549-2513 to request one. Below are links to various online databases of MSDS. Haz Comm. training is available through the EH & S Department, please call 2513 for more info. We are currently in the process of purchasing a computer program for bar coding and a better labeling/tracking system for all chemicals on campus.
