7. Locate the eye wash and the safety shower in the NW corner of SC 217. Read instructions. Laboratory Space and its Safety Features

8. Portable fire extinguishers: In the lab, mounted on the west wall In the hallway, 30 ft left and opposite wall from the entry door. Fire Hose (last resort – should have been out of building by then): Fire hose is at either end of the hall just before the exit doors Turn red knob to activate Pull hose all the way out – it will come on automatically.

10. Personal Safety Including Personal Protective Equipment (PPE) Personal protective equipment, commonly referred to as "PPE", is equipment worn to minimize exposure to a variety of hazards. Examples include: gloves foot and eye protection protective hearing devices (earplugs, muffs) hard hats respirators full body suits. (From OSHA 3151-12R 2003)

11. Personal Safety Including Personal Protective Equipment (PPE) Of the PPE listed, for CHEM 1361: Required eye protection (enclosed goggles, not glasses) closed shoes (no sandals, flip-flops, or open shoes) long pants shirts or blouses that cover the torso (no midriff, tank tops, etc.) Recommended gloves (both nitrile and latex will be available) lab apron, lab coat, etc.

13. Material Safety Data Sheets (MSDS): Provide manufacturer information about each chemical used in the lab Are available through print copy or electronic means Must be supplied by companies to customers of their products Must be supplied to employees by employers according to the 1983 OSHA standard “Hazard Communication in the Workplace” (29 CFR 1910.1200) Are designed to basically answer four broad questions about a chemical Materials to be Used in the Laboratory

14. The sixteen sections of an MSDS are roughly grouped into providing answers to four questions about a material. (Based on ANSI Standard Z400.1) Question 1. What is the material and what do I need to know immediately in an emergency? Section 1. Product and Company Identification Section 2. Hazards Identification Section 3. Composition/Information on Ingredients Materials to be Used in the Laboratory

15. Question 2. What should I do if a hazardous situation occurs? Section 4. First Aid Measures Section 5. Fire Fighting Measures Section 6. Accidental Release Measures Materials to be Used in the Laboratory

16. Question 3. How can I prevent hazardous situations from occurring? Section 7. Handling and Storage Section 8. Exposure Controls/Personal Protection Section 9. Physical and Chemical Properties Section 10. Stability and Reactivity Materials to be Used in the Laboratory

17. Question 4. Is there other useful information about this material? Section 11. Toxicological Information Section 12. Ecological Information Section 13. Disposal Considerations Section 14. Transport Information Section 15. Regulatory Information Section 16. Other Information Materials to be Used in the Laboratory

18. Sources of MSDS Sheets: Available in hard copy in each laboratory for the chemicals in use Available for all chemicals in storeroom in Room 222, the storeroom Manufacturer’s web sites Using the term MSDS in any internet search engine will provide a large number of sources Example of an internet site: http://www.ilpi.com/msds/,http://www.ilpi.com/msds/ Materials to be Used in the Laboratory

19. National Fire Protection Association Codes (NFPA) NFPA codes – each colored diamond represents one aspect of a material’s hazards Red Yellow White Blue Materials to be Used in the Laboratory

25. Common sense should suggest the following to you: Never put anything in or near your mouth or eyes Broken glass will cut Hot glass will burn Those around you are liable to pose unexpected dangers Do not let chemicals come in contact with your skin Fume hoods should be used as necessary to avoid inhalation hazards Bookbags and backpacks in the aisles are a tripping hazard – put them in the southwest corner Awareness in the Laboratory

26. Common courtesy should suggest the following to you: Clean up after yourself Put equipment back in proper storage area Place hotplate (if cool) back in community drawer Properly organize the community drawers Wipe down your work area Lock your drawer and return the key to the keyboard Awareness in the Laboratory

27. Equipment and Supply Questions? See your instructor first If necessary, you may have to go to Room 222, the stockroom
