Using the “water” plate first, I washed my hands without soap, and touched quadrant 1. I repeated this step until I had touched each quadrant. Then, using the “soap” plate, I washed my hands with soap, shook off the water and touched the first section. Then I washed my hands again using soap, and touched the second section. Next, I used a brush and soap to wash my hands for 2 minutes, and then touched the third section.
3. Equipment- The equipment used for this lab are 150 mL beaker, Stirring Rod, Bunsen Burner, Test Tube, sink, 4. Procedure- Start off by filling a 150 mL beaker halfway with tap water, and then heat until boiling. Then set aside for later use. Add 3.0 mL of 1.0 M Copper (II) nitrate to the test tube.
Cover area with disinfectant soaked-paper towels or with dry disinfectant. Allow a 20 minute contact period. Wipe down any contaminated stationary equipment or furniture with disinfectant. Use forceps, tongs, or broom to remove broken glass and other items; place in sharps container or red bag. Remove towels and re-clean area with disinfectant solution.
-Get six wooden splints that have been soaked in water. -Place them in the beaker half filled with water to continue soaking at your lab station. -Fill a second 250-mL beaker about half-full with tap water. Label this beaker “rinse water.” -Light the Bunsen burner. -Take one of the wooden splints and dip the soaked end in one of the metallic salts,
17. Repeat Steps 12 through 16 above for well #2 and well #3 and record your data under the Trial 1 column in the Data Table 1. 18. Wash the well plate immediately with liquid soap and dry the well plate thoroughly with paper towel and cotton swabs to remove any precipitate from the bottom of
(16 points) Immediately rinse the spills on the skin with continuous (running) water, and then soap the affected. Afterwards, notify the instructor(s). 3. List three things than one can do to protect oneself from contamination/injury in the laboratory. (24 points) -Keep hair tied back, free and clear from lab experiments.
Patient cleaned cut with peroxide and applied a Band-Aid, when he should have washed it thoroughly with soap and water and applied an antibacterial cream every day. Cover with a bandage and change it every day until a scab forms. And watch for redness, pain, drainage, or other signs of infection. (www.nlm.nih.gov, Linda J. Vorvick, MD) The fish tooth led to an infection, because seawater is full of infectious microorganisms. All wounds, even minor cuts and scrapes, should be treated as contaminated and potentially serious and should be carefully cleaned to prevent infection.
Allow the precipitate to settle, and heat 30 mL distilled water. Weigh, fold and place two filter papers into funnels and seal with distilled water. Decant a 50 mL sample from each beaker of solution into two other beakers. Pour the rest of the solutions into the respective funnel filters, and make sure to wash all precipitate into the filter, using the heated distilled water. Remove and air dry the filter papers containing the precipitates.
After donning the appropriate safety gear I began by placing 3 separate sets of 10 drops of distilled water into an unused well of the 24 well plate. I added the following chemicals into one of the three sets of distilled water creating three separate chemical mixtures: HCI, Ammonia, and Sodium Hydroxide. I mixed all thoroughly with a toothpick and then sucked the mixtures into separate pipets. These were placed into the 24 well plate for later use. Using the 96 well plate I combined various chemicals together to observe the chemical changes that were created.
