The aspirator was turned to medium high, and then the copper was poured onto wetted filter paper. Using distilled water to remove all copper from the beaker. Once completely on filter paper 6mL of acetone was added to the copper to help dry it out. The filter paper was then removed and set down to dry completely. Once dry the filter paper was weighed with the copper on it and subtracted from the original weight to see the amount of copper left after
Make sure you have all equipment needed and make sure you know how to use it before processing the crime scene. Collection methods: When a large mound of evidence needs recovering then you must remove the entire object, for small particulates use a vacuum. Scrape dried samples on none absorbent surfaces and cut dried samples on porous surfaces and swap wet samples. You must cast footprints, tool marks and teeth impressions. Use tape to tape lift hairs, fibres, paints, particulates and prints.
They should also clean any surfaces e.g. windowsills, door handles, tables, sinks. Floors should also be cleaned with disinfects to kill any germs. routinely clean all visibly dirty items such as bedside tables and night. Cleaners in a care home should clean towels daily, the kitchen should also be cleaned daily and the bathroom and toilet should be cleaned with disinfectant as all the
Use the 1.0mm opening for 1.6mm fiber. Also trim the Kevlar to the ‘C’ length using the electrician style scissors. * Using the marker pen and the template card provided, measure and mark the buffer strip length as shown on the template. * Using the buffer strippers, strip off the buffer in at least two pieces. * Using a dry, lint-free wipe; Remove any remnants of the protective coating on the fiber after stripping the buffer.
Pour the contents of one of the test tubes into the other and a reaction should occur and you should see a white precipitate of barium sulfate form. Then, centrifuge it for 1 minute. On the side, weight a boiling test tube containing 2 boiling chips. When the separation is complete, remove the small test tubes from the centrifuge and decant the supernatant into the boiling test tube. Add 1 mL of deionized water to the small test tube containing the precipitate and mix it and centrifuge it for 60 seconds.
Next was the ammonia test 10 drops of each metal solution were added to new centrifuge tubes and 15 M NH4OH was added until the solution changed color or a precipitate was formed. 10 additional drops of 15 M NH4OH were added and changes were recorded. For the confirmation flame test 20 drops of the metal solutions were added to centrifuge tubes. A Bunsen burner was set up using a striker to lite the flame, and a Nichrome loop was dipped in 10 mL of HCL and placed in the flame till no color was observed. Then the Nichrome loop was dipped in each tube of metal solution, (dipping the loop into HCL and in the flame after each solution) and placed in the flame and color was observed for each metal solution.
Cleaning, decontamination and waste management (IC 03) Unit 1 Understand how to maintain a clean environment to prevent the spread of infection 1.1 State the general principles for environmental cleaning • All cleaning equipment should be clean and maintained properly •Work surfaces and floors should be clean and intact, clear of clutter, dust free and good quality •GDP and water should be used (following the manufacturer’s instructions) Disinfectant should only be used to decontaminate spills of bodily fluids or for cleaning of an area after an outbreak of an infection •All cleaning equipment should be colour coded for different areas, as per National colour coding guide •Mop heads and
Treat casualties with the most serious conditions first and arrange for appropriate help. Washing hands and wearing latex free disposable gloves covering cuts and grazes on hands with waterproof dressing, wearing a plastic apron if dealing with large quantities of body fluids and wearing plastic glasses to protect eyes. Safe disposal of waste also avoid touching
Identify the processes (e.g., coagulation) that were used in this lab and describe how they were performed. You start out with the contaminated water that has not been filtered out or has not had any chemicals added to it, this is many done so air can meet the water and this gives the chemicals and gases to release. I then added Alum to the dirty water since when mixing Alum with the dirty water it allows all the big particles to “stick” to the Alum and then pushes all of these particles to the bottom of the water. The dirty water is then put through a filter of sand, charcoal, and gravel in order for any of the smaller particles to stick to them and makes the water clean and free of any other particle. After I did all this I then had to add a few drops of bleach so I could disinfect the water from any other dirt
7,8,Any spillages,i would clean thoroughly and as quickly as possible using the correct materials and equipment for that particular spillage.I would effectively wash my hands using an effective antibacterial soap,after collecting and disposing of body
