10. Hazardous Materials At This Facility • Types of hazardous materials • Locations of hazardous materials

11. How Hazardous Materials Enter Your Body • Skin absorption and eye contact • Inhalation

12. How Hazardous Materials Enter Your Body (cont.) • Ingestion (eatingcontaminated food) • Penetration through a cut, puncture, or injection

13. How Hazardous Materials Affect Your Body Match the term with its explanation below. Chronic Effects Acute Effects Dosage Amount of hazardous material you are exposed to Short-term effects that usually disappear when you are no longer exposed Long-term effects that develop over a period of exposure

14. PEL TLV TWA STEL Exposure Limits • Permissible exposure limit (PEL) • Threshold limit value (TLV) • Time-weighted average (TWA) • Short-term exposure limit (STEL)

15. What’s Wrong Here? • Worker assigned to clean screens • Given a cleaner, brush, and rag • Identify the hazard(s)

18. Review animation Read the Label • Identity of the material • Manufacturer contact information • Physical/health hazards • Special handling • PPE recommendations • First aid, fire response,and spill cleanup

19. What’s on the Label? The product label shows: • The name of the material • The manufacturer • Miscellaneous safety information • Hazard warnings • List of hazardousingredients • The product label shows: • The name of the material • The manufacturer • Miscellaneous safety information • Hazard warnings • List of hazardousingredients Image Credit: University of Utah, Physics Department

20. NFPA Labeling Systems • Blue = Health hazard • Red = Flammability • Yellow = Instability • White = Other hazards • Numbers: 0 (No Hazard) to 4 (Extreme Hazard)

21. In-Plant Labeling • Use for: • Secondary containers • Stationary process containers or vessels • Portable or temporary containers • Include tags and process batch sheets

22. Information Resource: The MSDS • Is a written description of a hazard related to a material • Describes the risks, precautions, and remedies to exposure • Must be readily available to you • Read the MSDS before working with any material!

23. The MSDS(cont.) • Identity of material and manufacturer • Ingredients • Hazards • First-aid and fire-fighting measures

24. The MSDS(cont.) • Accidental release • Handling and storage • Exposure controls and PPE • Physical and chemical properties • Stability, reactivity, toxicity • Ecological and disposal info • Transportation, regulatory, and other info

25. Labels and MSDSs • Do you understand about properties of materials, labeling, and the contents of MSDS?
