A Mobil Material Safety Data Bulletin (MSDB), commonly referred to as a Material Safety Data Sheet (MSDS), is a compilation of healthrelated information, procedures for emergency situations, physical properties, and recommendations to help assure the safe handling of a particular Mobil product.
The MSDB meets all of the requirements of the OSHA Hazard Communication Standard (29 CFR 191 0.1200). As an additional customer service, we provide an MSDB for our nonhazardous products as well.
Mobil provides an MSDB upon initial purchase, within 3 months of a significant change in hazardous product MSDB information, and upon first purchase each year for products containing a SARA 313 regulated ingredient. An MSDB may be requested at any time by calling the MSDS information number indicated in Section 1 of the MSDB. Some MSDBs are available on the Internet (
The following explanations of section contents are provided, ordered as you will find them within the U.S. MSDB. Please refer to the MSDB as you go through the following 16 sections which conform to the ANSI Z400.11993 standard and international formats.

Section 1. Product and Company Identification
Indicates if MSDB is based on supplier information. Indentifies the product trade name as it appears on the product container; our address and telephone numbers; and the date the MSDB was last revised. Please use the Product and MSDS Information phone number to request data regarding product applications and to obtain an MSDB. The emergency number is for urgent health, release, and transportation situations. The CHEMTREC number is for reporting transportation emergencies.

Section 2. Composition/Information on Ingredients
Ingredients disclosure in this section is based upon exposure limits and definitions of hazardous components considered relevant in the U.S., subject to applicable trade secret protections.
Chemical Names and Synonyms – A generic description of product components.
Ingredients Considered Hazardous to Health – Lists chemicals present above certain concentrations which either have exposure limits or have been determined to be hazardous by Mobil. The Chemical Abstract Service (CAS) number and approximate weight percentage is listed for each chemical. The exposure limits for these chemicals are listed in Section 8 of the MSDB.
Other Potentially Hazardous Ingredients – Lists chemicals present above certain concentrations which do not have regulatory exposure limits but which are physical (combustible, flammable, etc.) or health (defat skin, etc.) hazards. Includes CAS number and approximate weight percentage for each chemical.
Footnotes – Provides other amplifying information.

Section 3. Hazards Identification
Summarizes key emergency response information including a statement of whether or not the product is hazardous by the criteria in the OSHA Hazard Communication Standard; effects of overexposure to the product; physical appearance; unusual fire and explosion hazards; DOT Emergency Response Guide (ERG) number; and for Mobil use, a numerical Safety Equipment Code (SEC) which indicates hazard severity for MCCCPD materials.

Section 4. First Aid Measures
Contains recommended first aid procedures for relevant types of exposure (e.g., eye contact, skin contact, inhalation, or ingestion). Also includes notes to treating physicians. The information is for emergency situations only.

Section 5. Fire Fighting Measures
Recommends suitable extinguishing media, gives fire fighting instructions based on criteria established by the National Fire Protection Association (N EPA), gives advise on any special protective equipment for fire fighters (such as selfcontained breathing apparatus), and identifies any unusual fire and explosion hazards.

  • Flash Point – Temperature at which a material will generate sufficient vapor to ignite in the presence of an ignition source. OSHA classifies a material with a flash point below 100ºF as flammable, and with a flash point at or above 100ºF and below 200ºF as combustible. The DOT defines materials with a flash point of 141º or less as flammable,  and with a flash point between 141ºF and below 200ºF as combustible. Both OSHA and DOT require that flash points be determined using closed cup methods such as ASTM D93 or ASTM D56.
  • Flammable Limits – The range of gas and vapor concentrations (percent in air) which will burn in the presence of an ignition source. Flammable range is expressed as Lower Explosive Limit (LEL) and Upper Explosive Limit (UEL). If the flash point is above 250ºF, no flammable limits are shown on the MSDB.
  • NFPA Hazard ID – Coding system developed by the NFPA. Codes of 0 to 4 are assigned to the categories of Health, Flammability, and Reactivity. The lowest level of hazard is 0, and the highest is 4. For nonfire situations, the NFPA code and the Hazardous Material Information System (HMIS) code are identical. For fire situations, the HMIS Health code may differ from the NEPA Health code.
  • Hazardous Decomposition Products – Combustion byproducts which may be formed if the product is burned.

Section 6. Accidental Release Measures
Recommends procedures and precautions to be taken in the event of an accidental release or spill. Procedures for disposing of the product are given in Section 13. The reporting requirements indicated are for federal regulations. Since state and local reporting requirements may also exist, consult state and local law for guidance.

Section 7. Handling and Storage
Recommends any special precautions to be followed during the handling and storage of Mobil products. If a product is OSHA hazardous, the precautionary warning label text will be shown in Section 16.

Section 8. Exposure Controls/ Personal Protection
As a consequence of Mobil s Product Stewardship Program, many of our products are nonhazardous. Product toxicity, or lack thereof, is determined in our Toxicology Testing Program. When there is potential for adverse health effects from direct exposure to the product as packaged for sale, recommendations are made for general ventilation, and for respiratory, eye and skin protection. Depending on customer use conditions, need for protective measures may vary.
Regulated components of products are also shown in this section, along with their airborne exposure limits. Terms associated with exposure limits include:

  • Source – Indicates organization that established the exposure limit.Mobil – Exposure values utilized by Mobil for its facilities are displayed if they are = or < the corresponding ACGIH TLV.
  • ACGIH - American Conference of Governmental Industrial Hygienists establishes Threshold Limit Values (TLV).
  • OSHA – Occupational Safety & Health Administration establishes Permissible Exposure Limits (PEL).
  • TWA – Time Weighted Average is the airborne concentration of a substance averaged over a normal eight hour workday.
  • STEL – Short Term Exposure Limit – is the airborne concentration of a substance typically averaged over a 15 minute period. Used for substances with potential health effects as a result of a brief exposure to a high concentration.
  • ppm – Parts of gas or vapor per million parts of air. Common unit of measure for exposure limits for gases or vapors.
  • mg/m3 – Milligrams of a substance per cubic meter of air. Common unit of measure for exposure limits for dusts or mists.
  • Note – Provides further exposure limit information such as Ceil for ceiling limits which may not be exceeded during any part of the work day.
