    Safety is always the first concern in a lab. Prior to the lab, students were asked to identify where the eye wash station was, the fire extinguisher and blanket were, and the safety shower was. When working with chemicals it is essential to wear safety glasses. Since the students were informed of which chemicals were going to be used prior to the experiment, the students should look at the Material Safety Data Sheet to see what safety concerns may come with the chemicals being used. In the experiment, the students worked with acids. To avoid spilling acids on their persons, the students used syringes to control where the acids were going to be placed. Also, at the end of the experiment, students properly disposed of the laboratory waste and washed their hands, washing away any chemicals that they may have come in contact with.…

    When using acids or bases in a lab proper eyewear, gloves, and aprons should be worn if necessary. The chemicals should be kept from the eyes and skin, and if happen to get in eyes use an eye wash or shower immediately. When mixing chemicals: read and reread labels, only mix chemicals when told to by teacher and use the proper sized (usually smaller) container. When using acid only add acid to water, not the reverse order. In the case of an accident, report the spill to teacher immediately. Upon lab clean up, throw materials in proper containers and do not pour acids down the…
