All chemical storage cabinets should be clearly labeled to identify the hazards inside (e.g. “Flammables,” “Corrosives,” or “Oxidizers.”). Signs and labels for this purpose are available from Environmental Health and Safety at firstname.lastname@example.org
High hazard areas in the laboratory, such as ethidium bromide or acrylamide work stations, high voltage areas, and human material work stations, should be labeled. Signs for this purpose are available from Environmental Health and Safety at email@example.com
Reminder: Please do not leave loose items such as kimwipes, paper towels, aluminum foil in chemical fume hoods. These materials can easily get loose and fly into the rear baffles of the hood. This, in turn, disrupt the proper airflow inside the ducts. If you have something get loose, contact Physical Plant personnel to help you remove it.
Chemical fume hoods are the primary engineering control available to laboratory workers.
1.) First, identify and use administrative controls: Administrative controls are procedures used to control and minimize exposure to chemicals. Substitute a non-hazardous or less hazardous chemical for a more hazardous chemical. Alter your procedure so that smaller quantities may be used or so that the flow of work can be made safer.
1. I need to treat my cell culture plates with volatile chemicals. Should I use a Biological Safety Cabinet (BSC) or a Fume Hood (FH) to do my work? - A Fume Hood will not protect your cells from contamination, and therefore, should not be used if you require aseptic conditions for your work (e.g., if you need to pass cells or continue an experiment in which cells must be placed back in the incubator). You could use the Fume Hood for a terminal procedure, such as RNA isolation with Trizol.
