  6. Purpose of Hazard Communication • To ensure that employers and employees know about work hazards and how to protect themselves so that the incidence of illnesses and injuries due to hazardous chemicals is reduced. Section Two

  7. Texas Hazard Communication • Applies to all employees working for this state who may be exposed to hazardous chemicals under normal operating conditions or foreseeable emergencies Section Two

  8. Texas Hazard Communication An official Texas Department of State Health Services “Notice to Employees” must be posted at the location(s) within each workplace where notices are normally posted Section Two

  15. Material Safety Data Sheets Information • Identification • Manufacturer Name and Address • Physical and Chemical Characteristics • Physical Hazards • Health Hazards • Routes of Entry • Exposure Limits • Carcinogenicity • Safe Handling • Emergency and First-Aid Section Two

  16. Primary Container Labeling • Identity • Hazards • Manufacturer Section Two

  17. Secondary Container Labeling • Identity (as it appears on the MSDS) • Hazards (words, pictures and/or symbols) (In research laboratory, chemicals must be readily identifiable) Section Two

  18. OX-Oxidizer ACID-Acid ALK-Alkali W-Use no Water Labeling:N.F.P.A. 704 Flash Point 4-Below 73oF 3-Below 100oF 2-Above 100oF Not Exceeding 200oF 1-Above 200oF 0-Will Not Burn 4-Deadly 3-Extreme Danger 2-Hazardous 1-Slightly Hazardous 0-Normal 4-May Detonate 3-Shock and Heat May Detonate 2-Violent Chemical Change 1-Unstable if Heated 0-Stable Section Two

  19. Labeling D.O.T. Section Two

  20. Labeling • N.F.P.A. • D.O.T. Section Two

  21. Safety Considerations • Hazard • The source of danger (chemical, electrical, hot surface, etc.) • Risk • The likelihood of occurrence (Taking into account the length of exposure to the hazard) • Consequence • Outcome & Impact (due to exposure to the hazard) Section Three

  32. Compressed Gases • Gases -- Toxic, Corrosive, Flammable, Explosive • Hazards • Weight • Sudden release of pressure • Regulator (appropriate type) • Properly Secured • Report any Leaks • Have Identification • Know Procedures • Remove Empty Cylinders Section Three

  33. Liquid Cryogens • Cryogens, such as liquid nitrogen, oxygen, and helium are extremely cold liquids that can produce a painful burn. • Cryogens can expand rapidly and must never be contained in a closed system. • Eyes and bare skin can be injured immediately if they come into contact with cryogens. Section Three

  34. Liquid Nitrogen Burn to the Hand Section Three

  35. What Should I Look For on Cryogenic Cylinders? • Cylinders should be tested every five years. Contact EHS for details. • Look for swelling (ribbing) of the external tank. If evidence exists, contact EHS immediately! Section Three

  36. What Should I Look For on Cryogenic Cylinders? • Report any excessive venting or leakage to the vendor and EHS. • Always check that a pressure relief valve and rupture disc are present on the cylinder prior to filling or usage Section Three
