Safety Data Sheets (SDS)

What is a Material Safety Data Sheet (SDS)?

A safety data sheet (SDS) is a document that contains information on the potential health effects of exposure and how to work safely with the chemical product. It is an essential starting point for the development of a complete health and safety program. It contains hazard evaluations on the use, storage, handling and emergency procedures all related to that material. The SDS contains much more information about the material than the label and it is prepared by the supplier. It is intended to tell what the hazards of the product are, how to use the product safely, what to expect if the recommendations are not followed, what to do if accidents occur, how to recognize symptoms of overexposure, and what to do if such incidents occur.

Always be familiar with the hazards of a product BEFORE you start using it. You should look at a SDS, match the name of the chemical on your container to the one on the SDS, know the hazards, understand safe handling and storage instructions, as well as understand what to do in an emergency.

HEALTH HAZARD DATA Routes of exposure: Dust, mist and/or fumes generated during physical or metallurgical treatment may be inhaled, swallowed or come in contact with the skin or eyes. Effects of overexposure: Molybdenum dust and fumes (formed above 400° C) can cause irritation of the eyes, nose, throat, and respiratory tract. There are no recognized long term effects attributed to industrial exposure to molybdenum. In general, Molybdenum and its compounds are considered to be of low toxicity. Emergency and first aid procedures: Applicable for dust, mist and fumes. Inhalation: If irritation occurs, remove from exposure. Seek medical attention. Skin contact: If irritation occurs, thoroughly wash affected area with mild soap and water and prevent further contact. If irritation persists, seek medical attention. Eye contact: If irritation occurs, flush with copious amounts of water. If irritation persists, seek medical attention. Ingestion: If substantial quantities are swallowed, give person (if conscious) a large quantity of water to drink, induce vomiting and seek medical attention. Carcinogenic assessment (NTP annual report, other): None of the components of this material have been identified as known or suspected carcinogens by NTP or OSHA.
FIRE AND EXPLOSION HAZARD DATA Flash point: NA Flammable limits: NA Extinguishing media: fine dust generated during grinding operations may ignite if allowed to accumulate and subjected to an ignition source. Cover burning material with an inert powder, such as dry sand or limestone, to exclude oxygen. Special fire fighting procedures: For a powder fire confined to a small area, use a respirator approved for toxic dusts and fumes. For a large fire involving this material, firefighters should use self-contained breathing apparatus. Unusual fire and explosion hazards: Dust may present a fire or explosion hazard under favoring conditions of particle size, dispersion and strong ignition source. However, this is not expected to be a problem under normal handling conditions. ACGIH: American Conference of Governmental Industrial Hygienists NIOSH: National Institute for Occupational Safety and Health OSHA: Occupational Safety and Health Administration TWA: Time Weighted Average
REACTIVITY DATA Stability: (stable conditions to avoid): NA Incompatibility (materials to avoid): Avoid contact of dust with strong oxidizers and acids. Hazardous decomposition products: Molybdenum trioxide fumes may form when the metal is exposed to high temperatures. Hazardous polymerization: Will not occur. Conditions to avoid: NA
SPILL OR LEAK PROCEDURES Steps to be taken in case material is released or spilled: Applicable for grinding dust. Ventilate area or spill. Clean-up using methods which avoid dust generation such as vacuuming (with appropriate filter to prevent airborne dust levels which exceed the PEL or TLV), wet dust mop or wet clean-up. If airborne dust is generated, use an appropriate NIOSH approved respirator. Waste disposal method: Dispose of in accordance with appropriate government regulations. May be sold as scrap for reclaim.
SPECIAL PROTECTION INFORMATION Respiratory protection: Use an appropriate NIOSH approved respirator if airborne dust concentrations exceed the appropriate PEL or TLV. All appropriate requirements set forth in 29 cfr 1910.134 should be met. Ventilation: Use local exhaust ventilation which is adequate to limit personal exposure to levels which do not exceed the PEL or TLV. If such equipment is not available, use respirators as specified above. Protective gloves: Gloves are recommended when contact is likely. Eye protection: Safety glasses or goggles are recommended.
SPECIAL PRECAUTIONS Precautions to be taken in handling and storage: Maintain good housekeeping procedures to prevent accumulation of dust. Use clean-up methods which minimize dust generation such as vacuuming or wet clean-up. If airborne dust is generated, use an appropriate NIOSH approved respirator. Other precautions: Wash thoroughly after handling and before eating or smoking and at the end of the work shift. Do not shake clothing or other items to remove dust. Use a vacuum. Avoid dust inhalation and direct skin contact.

Employers must make sure that all controlled products have an up-to-date (less than three years old) SDS when it enters the workplace. The SDS's must be readily available to the workers who are exposed to the controlled product and to the health and safety committee or representative. If a controlled product is made in the workplace, the employer has a duty to make an SDS for any of these products. Employers may computerize the SDS information as long as all employees have access to and are trained on how to use the computer terminals, the terminals are kept in working order, and that the employer makes a hard copy of the SDS available to the employee or safety and health committee/representative upon request. The purpose of a Safety Data Sheet (SDS) is to inform industrial purchasers and users of hazardous chemicals of the reasonably foreseeable physical and chemical hazards that may arise from the use of those chemicals. Most materials packaged for consumer use are exempt from the requirements of the Hazard Communication Standard (HCS). The SDS should include precautions for normal use, handling, storage, disposal, and spill cleanup. It should not include recommendations for protective measures that are more strict than needed. OSHA states, in the inspection procedures for the HCS,10 "Some SDSs include recommendations for protective measures that are for 'worst case scenarios,' e.g., recommending supplied air suits for products of relatively low toxicity. The HCS requires that accurate information be provided on the SDSs. This applies as much to 'overwarning' on the SDS and label as well as the absence of information ('underwarning')."

OTHER REGULATORY INFORMATION
The following chemicals are specifically listed by individual states: other product specific health and safety data in other sections of the MSDS may also be applicable for state requirements. For details on your regulatory requirements you should contact the appropriate state agency.


Employers must make sure that all controlled products have an up-to-date (less than three years old) SDS when it enters the workplace. The SDS's must be readily available to the workers who are exposed to the controlled product and to the health and safety committee or representative. If a controlled product is made in the workplace, the employer has a duty to make an SDS for any of these products. Employers may computerize the SDS information as long as all employees have access to and are trained on how to use the computer terminals, the terminals are kept in working order, and that the employer makes a hard copy of the SDS available to the employee or safety and health committee/representative upon request. The purpose of a Safety Data Sheet (SDS) is to inform industrial purchasers and users of hazardous chemicals of the reasonably foreseeable physical and chemical hazards that may arise from the use of those chemicals. Most materials packaged for consumer use are exempt from the requirements of the Hazard Communication Standard (HCS). The SDS should include precautions for normal use, handling, storage, disposal, and spill cleanup. It should not include recommendations for protective measures that are more strict than needed. OSHA states, in the inspection procedures for the HCS,10 "Some SDSs include recommendations for protective measures that are for 'worst case scenarios,' e.g., recommending supplied air suits for products of relatively low toxicity. The HCS requires that accurate information be provided on the SDSs. This applies as much to 'overwarning' on the SDS and label as well as the absence of information ('underwarning')." Each Safety Data Sheet shall be in English, and shall contain at least the following information:
  1. 1. The identity (product name) used on the label, and chemical and common name(s) of ingredients which have been determined to be health hazards, and which comprise 1% or greater of the composition, except carcinogens shall be listed if the concentrations are 0.1% or greater; and,
  2. 2. The chemical and common name(s) of all ingredients which have been determined to present a physical hazard when present in the mixture;
  3. 3. Relevant physical and chemical characteristics of the hazardous chemical (such as vapor pressure, flash point);
  4. 4. Relevant physical hazards, including the potential for fire, explosion, and reactivity;
  5. 5. Relevant health hazards, including signs and symptoms of exposure, and any medical conditions generally recognized as being aggravated by exposure to the chemical;
  6. 6. The primary route(s) of entry into the body;
  7. 7. The OSHA permissible exposure limit and ACGIH Threshold Limit Value. Additional applicable exposure limits may be listed;
  8. 8. Whether the hazardous chemical is listed in the National Toxicology Program (NTP) Annual Report on Carcinogens (latest edition) or has been found to be a potential carcinogen in the International Agency for Research on Cancer (IARC) Monographs (latest editions), or by OSHA;
  9. 9. Precautions for safe handling and use, including appropriate hygienic practices, protective measures during repair and maintenance of contaminated equipment, and procedures for clean-up of spills and leaks;
  10. 10. Appropriate control measures, such as engineering controls, work practices, or personal protective equipment;
  11. 11. Emergency and first aid procedures;
  12. 12. The date of preparation of the Safety Data Sheet or the last change to it; and;
  13. 13. The name, address and telephone number of the chemical manufacturer, importer, employer or other responsible party preparing or distributing the Safety Data Sheet, who can provide additional information on the hazardous chemical and appropriate emergency procedures, if necessary.
  • If no relevant information is found for any given category, it should be marked to indicate that no applicable information was found.
  • If significant new information becomes available regarding the hazards of a chemical, or ways to protect against the hazards, this new information shall be added to the Safety Data Sheet within three months.
  • A Safety Data Sheet must be provided with the initial shipment of a hazardous chemical, and with the first shipment after a Safety Data Sheet is updated.
  • Safety Data Sheets shall also be made readily available, upon request, to designated employee representatives and to OSHA representatives.
