ENGR 100W Make-up Lab Assignment Dr. Thalia AnagnosENGR 100W Make-up Lab Assignment Dr. Thalia AnagnosObjectives of Assignment:- Summarize information drawn from several sources- Write an organized summary report Background: The Occupational Health and Safety Administration (OSHA) requires that all chemicals in the workplace be labeled properly so that workers handle them safely and avoid exposing themselves to potential health hazards. All chemicals sold or stored must be accompanied by a Material Safety Data Sheet (MSDS), which provides information about physical properties of a chemical (specific gravity, melting point, boiling point, flash point, etc.), flammability, health effects, preventative measures (protective equipment, disposal, storage, etc.), and first aid (NFPA, 2008).The NFPA 704 Hazard Identification ratings (also known asdiamond ratings) provide succinct and easy to recognizeinformation about hazards of a particular material. NFPA 704signs are optional and may be posted in buildings to alertworkers and the public to potential hazards. According to theNational Fire Protection Association:The system is characterized by the "diamond shape" thatis actually a "square-on-point" shape. It identifies thehazards of a material and the degree of severity of thehealth, flammability, and instability hazards. Hazardseverity is indicated by a numerical rating that rangesfrom zero (0) indicating a minimal hazard, to four (4) indicating a severe hazard. The hazards are arranged spatially as follows: health at nine o'clock position, flammability at twelve o'clock position, and instability at three o'clock position. In addition to the spatial orientation that can be used to distinguish the hazards, they are also color-coded as follows: blue for health, red for flammability, and yellow for instability. The six o'clock position on the symbol represents special hazards and has a white background. The special hazards in use are W, which indicates unusual reactivity with water and is a caution about the use of water in either fire fighting or spill control response, and OX, which indicates that the material is an oxidizer. (NFPA, 2008)A very short description of the rating system is found at www.delta.edu/slime/nfpakey.html.Assignment: OSHA will be inspecting the labs at EnvironSJ in June. Your boss, Daniel Detailman, wants to make sure that all the labs have proper postings for the chemicals so that OSHA does not cite EnvironSJ for any violations. He wants you to do an inventory of the labs, review the MSDS sheets for the chemicals, and summarize the contents of the NFPA 704 diamonds that EnvironSJ should post in each lab.Page 1ENGR 100W Make-up Lab Assignment Dr. Thalia AnagnosThis is what you found:- Laboratory 122 uses liquid chlorine (find MSDS at http://www.stoodyind.com/safety/msds/chlorineMSDS.pdf)- Laboratory 306 uses benzene(find MSDS at http://www.sciencelab.com/xMSDS-Benzene-9927339)- Laboratory 150 uses machine lubricant(find MSDS at http://www.le-inc.com/msds/0300.pdf)Write a memo to Mr. Detailman summarizing your findings. Your memo should summarize the chemicals that are used in each lab and the NFPA 704 signs to be posted in each lab. As part of your memo you MUST include a table summarizing for each lab the chemical used and the contents of each of the four areas of the diamond sign. You might want to give him a quick reminder of what the four parts of the diamond represent. Be sure to let Mr. Detailman know where he can find more information on the NFPA 704 rating system if he needs it.Guidelines: The assignment must be turned in at the end of this class period and a copy MUST BE TURNED INTO TURNITIN.COM (if not -5 points). Complete the memo with 12 point Times Roman font, 1 1/2 line spacing, and 1- inch margins. Proofread your document before you print it. Submit an electronic copy to Turnitin.com and turn in the hard copy. Grading:Proper introduction and conclusion 3Quality of summary of information Mr. Detailman asked for 4Complete and well formatted table 4Correct grammar, spelling, punctuation, and referencing 4 Total 15 pointsReferences:NFPA (National Fire Protection Administration) (2008).
