The washing should continue for 15 to 20 minutes. Send someone else to notify the instructor if he has not seen the accident. It is not recommended to wear contact lenses in the laboratory. Students are especially cautioned about the soft type of contact lenses, since vapors tend to collect at the surface of the eye. If you decide to disregard this recommendation and still wear contact lenses in the laboratory, you must put a green dot on the top of your safety goggles to signify to the instructor that in the event of an accident the contact lenses must be removed.
Nothing is ever to be tasted in the laboratory.
This means, of course, that one must not eat, drink, or smoke at any time in the laboratory. Be very careful when noting odors, and avoid breathing any fumes. All chemicals must be considered to be hazardous, i.e., flammable, toxic, and corrosive, unless instructed otherwise. When in doubt, assume the worst and use the hood and shields. Never point a test tube toward another person or toward yourself, for the contents may bump.
