laboratory that uses it for experimentation, it is very important that users of
the laboratory must be oriented about their safety and the code of the
laboratory. For one, it will allow you to be alert at all times when using for
example, an unknown chemical. Two, it will help you understand how to use the
apparatus present inside the laboratory. Three it will protect you against
unforeseen events. So before viewing prepared slides under a microscope, the
students should review the safety rules if there are accidents such as; cutting
yourself from the prepared slide, informing the professor if the prepared slide
is broken, asking the laboratory-in-charge for assistance on how to use the
microscope. That way, the flow of the class will run smoothly.</span>
