. T Locate where the fire safety equipment like blankets, fire extinguisher, fire alarms etc are in the lab so that in case of an accident you know where to look for one. Special precautions on how to use the instrument First light the splinter before turning on the Bunsen burner and use the valves and collar to control the amount of gas and oxygen flowing in through the hole so that the flame burns blue and not yellow. Blue flames are oxygen-rich therefore they burn hotter and yellow flames are oxygen-deprived so they are comparatively cooler than blue flames. Also, yellow flames tend to be uncontrolled, and in comparison blue flames then to be controlled. Since the Bunsen burner is a source of open flame, care must be taken to locate and operate it away from flammable material.

4 . . . Special precautions on how to use the instrument UT %. Locate where the fire safety equipment like blankets, fire extinguisher, fire alarms etc are in the lab so that in case of an accident you know where to look for one. First light the splinter before turning on the Bunsen burner and use the valves and collar to control the amount of gas and oxygen flowing in through the hole so that the flame burns blue and not yellow. Blue flames are oxygen-rich therefore they burn hotter and yellow flames are oxygen-deprived so they are comparatively cooler than blue flames. Also, yellow flames tend to be uncontrolled, and in comparison blue flames then to be controlled. Since the Bunsen burner is a source of open flame, care must be taken to locate and operate it away from flammable material. Always use a tong for test tubes and a stand with wired mesh for beakers when heating reaction mixtures on an open flame. If the reaction mixture in the test tube contains biomolecules, then heat it in a water bath(a beaker containing water, heated on Bunsen flame ). Open flames from the bunsen burner tend to unevenly heat the reaction mixture and the mixture can boil out of the test tube unpredictably and cause burn injuries.
