| Saksham | Re: NIOS Physics Lab Manual You want to get NIOS Physics Lab Manual so here I am giving you: SAFETY IN A SCIENCE LABORATORY Science laboratory is an exclusive work place for sincere workers. Go there with a sense of devotion and work honestly. A little carelessness can lead to accidents by which not only you may harm yourself but your neighbours too. Proper handling of apparatus, chemicals and other materials in the laboratory can prevent majority of accidents. Remember the following points while working in a science laboratory. Use all chemicals carefully. Replace the reagent bottles in their proper position after use. Do not mix chemicals unless required. Do not taste chemicals. Before using a chemical make sure it is the right chemical. Put off the gas to extinguish the flame of burner. Do not use any solid or liquid for this purpose. While pouring acids in the sink after use, do not forget to keep tap-water on so that they are completely flushed out. Do not keep volatile liquids such as alcohol, ether, acetone, etc. near the flame as these are highly inflammable. Do not throw broken glassware etc. in the sink. Such things should be thrown into the waste-paper basket. Do not talk to other students in the laboratory while performing the experiment. In case you have any difficulty, consult your teacher directly. Never point a test tube containing a reaction mixture or a mixture, which is being heated, towards your neighbour or yourself. Never pour water into concentrated acids. Rather add acid slowly to water in a container. Before leaving the laboratory wash your hands properly. Complete manual is given in attached pdf file of which link I am giving you. nios.ac.in/media/documents/secscicour/English/Lab_Manual_Final.pdf |
