  1. SAFETY IN THE CHEMISTRY LAB • What is a Material Safety Data Sheet (MSDS)? • designed to provide both workers and emergency personnel with the proper procedures for handling or working with a particular substance.

  2. Material Safety Data Sheet (MSDS) • MSDS's include any safety issue such as physical data (melting point, boiling point, flash point etc.), toxicity, health effects, first aid, reactivity, storage, disposal, protective equipment, andspill/leak procedures. • These are of particular use if a spill or other accident occurs.

  3. Hazard Identification label • Summarizes risks related to health, flammability and reactivity. • A number scale indicates the level of risk.

  4. MSDS • Every company that manufactures or distributes hazardous chemicals in the United States must prepare a Material Safety Data Sheet (MSDS). • Mandated by the Occupational Safety and Health Administration (OSHA) in their Hazard Communications Standard 29CFR 1910.1200. • This standard is commonly referred to as the Right-To-Know Law.

  5. What items or formats are required on an MSDS? • ALL U.S. MSDS's must includde the items found on OSHA’s Form 17. • You can include more items than OSHA requires. • The American National Standards Institute (ANSI) has a 16-part standard format which encompasses the areas given in the OSHA standard and adds a few more such as toxicology. • In fact, OSHA now recommends using the ANSI format!

  6. OSHA’s Form 17 • Chemical Identity • Section I. Manufacturer's Name and Contact Information • II. Hazardous Ingredients/Identity Information • III. Physical/Chemical Characteristics • IV. Fire and Explosion Hazard Data • V. Reactivity Data • VI. Health Hazard Data • VII. Precautions for Safe Handling and Use • VIII. Control Measures

  7. MSDS QUIZ • MSDS sheets must be written in: • A OSHA Form 174 format • B ANSI format • C EPA format • D Any format, but must contain the information found in OSHA Form 174. • E Any format; there are no specific requirements for content.

  8. MSDS QUIZ • MSDS's should be consulted: • A In case of fire or explosion • B Before working with a chemical • C In the event of a spill • D To prepare risk assessments • E All of the above

  9. What is the Emergency telephone number for information from the manufacturer?

  10. This manufacturer is located in:

  11. Which of the following is NOT a synonym or trade name of Benzoic Acid?

  12. The NFPAfire rating for benzoic acid is:

  13. What is the OSHA PEL for benzoic acid?:

  14. What is the Chemical Abstracts Number for benzoic acid?:

  15. Does Benzoic Acid have a recognizable odor? The boiling point of benzoic acid is:

  16. Benzoic Acid is soluble in:

  17. What is the vapordensity of Benzoic Acid?

  18. What is the flash point of benzoic acid?

  19. Is a carbon dioxide extinguisher an acceptable extinguishing medium for benzoic acid? Benzoic Acid is not compatible with:

  20. Benzoic acid: • Should not be stored. • Is one of the most reactive substances known • Is considered stable at normal pressures and temperatures. • Can spontaneously detonate, even when stored properly. • Is a volatile gas that should be stored in pressurized cylinders.

  21. Acute exposure to benzoic acid can cause: • Mild respiratory irritation (sore throat and coughing) • Cystic fibrosis • Lung cancer • Myocardial infarction • Bleeding of the mucous membranes.

  22. In the event that benzoic acid is spilled in the driveway of your facility you can simply flush the material into the storm sewer. • True • False The "reportable quantity" (RQ) for a spill of benzoic acid is: • 30 grams (1 ounce) • 1 pound • 1 kilogram (2.2 pounds) • 50 kilograms (110 pounds) • 2300 kilograms (5000 pounds)

  23. When benzoic acid is involved in a fire it: • may emit carbon monoxide and other toxic substances. • can polymerize and/or detonate. • will readily ignite. • is insoluble in water, so you don't need to worry about it running into the sewer. • No special precautions need to be taken..

  24. When selecting a respirator you need to pay attention to: • The contamination level • The working limits of the respirator • Making sure that it has been properlyfitted (taking particular care with facialhair) and that the user has been properly trained. • All of the above • No particular precautions are needed.

  25. What kind of eye protection is recommended for working with benzoic acid? • Safety glasses • Splash-proof or dust-resistant safety goggles • Face shield only • UV protective glasses with side shields • Full-face mask and respirator
