4) Discuss appropriate safety procedures practiced in the clinical laboratory when handling all chemicals, flammables, ether and compressed gases. 5) Discuss the information provided by and the appropriate use of the Material Safety Data Sheet (MSDS). 6) Discuss appropriate safety precautions practiced in the clinical laboratory when Organic chemistry - laboratory methods 3 Grading and Rules of evaluation The final grade will be weighted arithmetic mean of two grading elements: (1) lab work (60%) and (2) post-lab reports (40%) lab work will be graded twice - after 4th and 8th class; the lab work grade will be an arithmetic mean of those two Use a balance for precise weighing of chemicals for your lab. Chemistry labwork brings inherent risks. But, with proper precautions and prep, you can use chemicals as safely as possible. We highly recommend that you use safety equipment like goggles, gloves, and a lab apron when using chemicals impervious to the chemicals used. For example, many microbiological manipulations involve concurrent use of chemical solvents such as formaldehyde, phenol, and ethanol as well as corrosives. The lab bench must be resistant to the chemical actions of these substances and disinfectants. Wooden bench tops are not used to cover ends of test tubes and flasks spatula small scoop used to transfer powder and crystal chemicals spot plate a flat plate with multiple "wells" used as small test tubes stirring rod used for stirring The Laboratory Chemicals offered here, along with over 750,000 other Laboratory Items have been selected by The Lab Depot as high value lab supplies. Chemical Specifications Ultratrace, ACS: Suitable for use in ultratrace elemental analysis. Meets or exceeds the specifications as listed in Reagent Chemicals published by the American Chemical The CSB asked the American Chemical Society (ACS) for assistance with developing guidance that would address this information gap. The ACS accepted the CSB recommendation to: "Develop good practice guidance that identifies and describes methodologies to assess and control hazards that can be used successfully in a research laboratory." CHECKLIST FOR COMPLIANCE WITH OSHA LABORATORY STANDARD (CHEMICAL HYGIENE) [The "New Employee/Guest Orientation" form may be one method of compliance] . b. Use of chemicals in the laboratory is limited to non-production, small-scale operations. LabStandardChecklist.PDF Many are in aqueous solution, but they are also available as mixtures or pure compounds, such as Acrylamide, Formaldehyde, Glutaraldehyde, Chloroform, Phenol, Methylene chloride Toxic metal salts such as Silver chloride, Cadmium sulfate, Mercury acetate, Barium carbonate, Lead acetate, etc. LIST OF LISTS Consolidated List of Chemicals Subject to the Emergency Planning and Community Right- To-Know Act (EPCRA), Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) and Section 112(r) of the Clean Air Act • EPCRA Section 302 Extremely Hazardous Substances • CERCLA Hazardous Substances • Safe use of chemicals in the laboratory (correct storage, handling, and disposal) • Safe, appropriate use of heat sources in the laboratory • Proper prevention of exposure to bloodborne pathogens from sources such as sharp instruments (lancets, needles), tissues, and body fluids • First-aid procedures Synopsis.
