Unit 2, Task 1 Working in the Science Industry In this essay I am going to state the responsibilities which are carried out by Industrial Science Technician: Management of a chemical store Storage of chemicals is as notable to the security of an adequate management of chemicals. Often seemingly logical storage ideas can, such as placing chemicals in alphabetical order, causes incompatible chemicals are stored together. * Read chemical labels for specific storage instructions. * Store chemicals in a well-ventilated area; however, do not store chemicals in a fume hood. * Maintain an inventory of all chemicals in storage. * Return chemical containers to their proper storage location after use. * Store glass chemical containers so that they are unlikely to be broken. * Store all hazardous chemicals below eye level. * Never store hazardous chemicals in a public area or corridor. Ordering procedures of chemicals in Industrial Science Technician * Policy: All chemicals and commercial products, a mixture of chemical constituents is greater than or equal to 25 g / ml will be funded by the Environmental Health and Safety (EHS) ...read more.


or some other route, notify the EHS Coordinator so that the containers can be tagged with bar-code labels and entered into the chemical inventory. * Material safety data sheets (MSDSs): Department is required to file an MSDS for each hazardous chemical or commercial chemical product. Material Safety Data Sheets are summaries of the health, safety, and environmental information for a specific chemical or chemical mixture. * Contingencies: Arrangements will be made to provide service during long term absences of the EHS Coordinator. Each department will be notified of the alternate procedures for ordering and obtaining chemicals during these periods. * Empty chemical containers: place all empty containers in one of the blue recycling bins located in most of the laboratories. Calibration of equipments Most of the instruments and sensors have been developed to meet certain accuracy specifications; the process of adjusting an instrument to meet the specifications is called calibration. The device used to calibrate other instruments is known as the calibrator. Calibrators vary in form and function depending on the instruments with which they are intended to work. ...read more.


* Always wear gloves when handling waste containers. * Non-radioactive substances and materials must not be put in the containers for radioactive waste. * Use hazardous waste containers made from plastic with an airtight lid. Instrumentation technique A colorimeter is an instrument that the amount of light, always compare a solution with the amount you can by a sample of the pure solvent. Substances absorb light for a variety of reasons. Pigments absorb light at different wavelengths. A cloudy solution is simple scatter / block the passage of light (sometimes called a colorimeter is used to) monitor the growth of a bacterial or yeast culture. Different chemical substances absorb different frequencies of the visible spectrum. Colorimeters on the principle that the absorption means a substance to its concentration, a concentrated solution proportional to a higher absorbance. A filter in the colorimeter selects the frequency of light absorbed most of the solute in order to maximize the accuracy of the experiment. Note that the colour of the light absorbed the 'against' the colour of the sample, i.e. a blue filter would be appropriate for an orange-coloured fabric. Sensors measure the amount of light that has passed through the solution and a display showing the amount absorbed. http://www.offices.colgate.edu/chemmgt/chemicalmanagementguide.htm http://www.omega.co.uk/prodinfo/calibrators.html http://www .msds.chem.ox.ac.uk http://www.world-nuclear.org/education/wast.htm http://www.dartmouth.edu/~chemlab/techniques/calorimeter.html ...read more.
