All of the usual precautions for work with chemicals apply in the ALS Chemistry Laboratory. Some additional rules are necessary because it is a multi-user laboratory. Keep in mind that, while your own work may not require a given precaution, other users' work may involve hazards not obvious to you. Personal Safety Do not eat or drink in the laboratory. Wear eye protection at all times-other users' work may require it, even if yours does not.
Safety glasses are available outside the laboratory door.
As a safety precaution, it is recommended that another person be present in the laboratory if you are performing procedures in which hazardous conditions may occur. Labeling Label all equipment that you are responsible for with your name and a phone number at which you can be reached. Label and date all chemicals that are not in their original containers, giving the names of the chemicals and their physical and health hazards. Preprinted labels for some common chemicals can be found in the laboratory. Blank labels are available for all other chemicals.
