  1. Understanding MSDS Sheets Vincent J. Giblin, General President Phone: (304) 253-8674 Fax: (304) 253-7758 E-mail: hazmat@iuoeiettc.org 1293 Airport Road Beaver, WV 25813

  2. This material was produced under grant number 46C5-HT16 from the Occupational Safety and Health Administration, U.S. Department of Labor. It does not necessarily reflect the views or policies of the U.S. Department of Labor, nor does mention of trade names, commercial products, or organizations imply endorsement by the U.S. Government.

  3. Objectives Participants who complete the course will be able to: • Identify employee rights and employer responsibilities concerning MSDSs • Identify Health and Safety Hazards and control methods using a sample MSDS • Define key terms commonly used on MSDSs • Identify limitations of the MSDS * Objectives are described in detail in the student manual.

  4. Rights and Responsibilities A. Employermust obtainand provide MSDSs • right of employee to request MSDS • right of union representative to request MSDS • employer must have MSDS “readily available” • employer must have an MSDS for every hazardous chemical used • employer must provide MSDS to employee or union

  5. Rights and Responsibilities B. Employer must provide training • general training about the regulation, health and safety hazards and control methods • specific training for your workplace hazards

  6. C. Employer must have written HazCom program Rights and Responsibilities D. Employees must follow safety procedures

  7. MSDS Questions • Is this the MSDS for the product I am using? • Is the Chemical reactive? • Are there other chemicals or substances I should keep away from this chemical? • What are the health effects of this product?

  8. MSDS Sections • Identity (as on label) • Manufacturer’s Information • Hazardous Ingredients • Physical/Chemical Characteristics • Fire/Explosion Hazard Data • Reactivity Data

  9. MSDS Sections • Health Hazard Data • Precautions for Safe Handling and Use • Control Measures

  10. MSDS Sections Identity (as on label) NOTE: Blank spaces are not permitted . If any item is not applicable, or no information is available, the space must be marked.

  11. Manufacturers’ Information Emergency Phone Manufacturers’ Address Information Phone Date Prepared Signature Manufacturers Information

  12. Hazardous Components PEL/TLV % Hazardous Ingredients

  13. Exposure Limits Set by three organizations OSHA - PEL ACGIH - TLV NIOSH - REL

  14. Permissible Exposure Limit • Usually measured as ppm or as mg/m3 • As the PEL goes down, the toxicity usually goes up • 8-hour TWA (for working life time TWA=Time Weighted Average

  15. PPM = Part per million • ppm = 1 drop of chocolate in 14 gallons of milk • 1 shot glass to a tank car • 1 hour in 115 years or since the Civil war • 1 yard in 10,000 football fields

  16. PPM = Part per million $1 = 1 part per hundred = 1% $100 $1 = 1 part per million $1,000,000 1 = 1 part per million 1,000,000 1,000,000 = 1 (the whole) = 100% 1,000,000

  17. Milligrams Per Cubic Meter mg/m3 milligram = 1/29,000 of an ounce m3 = a cubic meter; a box about 39” x 39” x 39” 1/29,000 of an ounce in a box 39” x 39” x 39”

  18. PEL's AND TOXICITY PPM As the PEL goes down... 100 LESS TOXIC 50 The toxicity goes up. 10 TOLUENE ACETIC ACID

  19. PEL's AND TOXICITY PPM RESPONSE (symptoms or illness) 100 50 As the dose increases, so does the effect. 10 DOSE (concentration/time) 10 50 100

  20. Average exposure over 8-hour day (800 ppm X 8 hrs) = 800 ppm TWA = 8 hours (800ppm X 4hrs + 0ppm X 4hrs) = 400 ppm TWA = 8 hours (800 ppm X 10 hrs = 1,000 ppm TWA = 8 hours TWA = Time Weighted Average

  21. What is the TWA? #1 • Work at 800 ppm for 4 hours; 0 ppm for 4 hours. • Work at 800 ppm for 4 hours; 0 ppm for 4 hours. • PEL = 800 ppm. Is the worker overexposed?

  22. 800 PEL = 800 ppm 600 TWA = 400 ppm 400 Worker not overexposed. 200 0 ppm for 4 hours 800 ppm for 4 hours 0 1 2 3 4 5 6 7 8 9 10 11 12 3200+ 0 (800ppm X 4hrs + 0ppm X 4hrs) TWA = = = 400 ppm 8 8 What is the TWA? #1

  23. What is the TWA? #2 • Work at 800 ppm for 10 hours. PEL = 500 ppm. • Is the worker overexposed?

  24. 1,000 TWA = 1,000 ppm PEL = 800 ppm 800 600 400 Worker is overexposed. 800 ppm for 10 hours 200 0 1 2 3 4 5 6 7 8 9 10 11 12 (800ppm X 10 hrs) 8,000 TWA = = = 1,000 ppm 8 8 What is the TWA? #2 .

  25. TWA Story Problem • Product XYZ has an 8 hour TWA of 500 ppm. • Workday 7:00 a.m. to 3:00 p.m. with 1 hour for lunch. • Concentration is 600 ppm. What is the TWA exposure? Is this an over-exposure?

  26. What is the TWA? #3 • Work at 600 ppm for 7 hours; 0 ppm for 1 hour. • PEL = 500 ppm. Is the worker overexposed?

  27. 800 600 TWA = 525 ppm PEL = 500 ppm 400 600 ppm for 4 hours 600 ppm for 3 hours Lunch Worker is overexposed. 200 0 1 2 3 4 5 6 7 8 9 10 11 12 (600ppm X 4hrs + 0ppm X 1hrs + 600ppm X 3hrs) 2400+ 0 + 1800 = = 525 ppm 8 8 What is the TWA? #3

  28. Exposure Limits PEL Legal limit 8-hour TWA exposure Permissible Exposure Limit Short Term Exposure Limit STEL maximum 15-minute exposure Ceiling Exposure to never exceed not even instantaneously Immediately Dangerous to IDLH Life and Health

  29. Boiling Point Specific Gravity (Water = 1) Vapor Pressure Melting Point Vapor Density Evaporation Rate (Air = 1) (Butyl Acetate=1) Solubility in Water Appearance/Odor Physical Characteristics

  30. Boiling Point Temperature at which liquid turns to gas. As the temperature increases, the chemical releases more and more vapors... Gas At the boiling point, the chemical turns from liquid to gas. The lower the boiling point,the more vapors a chemical releases at room temperature. Liquid Temperature

  31. Water = 1.0 Lighter than water. Heavier than water. SG<1 SG>1 The Chemical will The Chemical will float on water sink in water Specific Gravity Weight of chemical compared to water.

  32. Vapor Pressure The force exerted by a chemical as it changes into a gas 10 mmHg 630 mmHg The more pressure a chemical exerts against air, the more vapor goes into the air.

  33. Air = 1.0 Heavier than air Same as air Lighter than air VD = 0.5 VD = 1 VD = 1.2 Hydrogen sulfide Carbon Monoxide Methane Vapor Density Weight of a vapor in relation to air. The larger the number, the heavier the vapor

Combine with other chemicals to produce hazardous chemical or energy byproducts INCOMPATIBLE Release oxygen than can support a fire or explosion OXIDIZER Combine with other chemicals or itself and release heat POLYMIZER Break down or combine easily to produce hazardous chemical or energy byproducts UNSTABLE Reactivity (on MSDS)

  43. REACTIVITY 1 M M POLYMERIZATION c M M MONO = 1 POLY = many A catalyst helps monomers... join to make polymers 2 3 Oxygen (O2) Fuel M M c HEAT M M Enough heat means fire/explosion Heat is released!
