Safety Data Sheets (SDS) Full safety data on all chemicals used in the laboratory are included in their Safety Data Sheet (SDS). For additional information on the properties of laboratory chemicals, consult the Material Safety Data Sheet (SDS) on that chemical or another resource. To minimize this risk, consult your instructor if you are pregnant. Many chemicals are thought to pose special risks to unborn children, especially during the first few months of pregnancy. Treat all chemicals in the lab as potential hazards. Also, do not place your mouth on any piece of equipment in the laboratory. Never bring food into the lab and never taste any chemicals in the lab. Handling Chemicals The easiest routes for possibly dangerous chemicals and vapors to enter the body are via inhalation or ingestion. The chemistry department is not responsible for such items and cannot replace any damaged or destroyed personal items, including laptops, calculators, cell phones, or clothing. Do not bring excess personal items into the laboratory where they may be subject to damage or destruction.

If you fail to do so, you will only be permitted to observe the experiment from a distance and lose a significant number of points. If you arrive for lab improperly dressed, you will be given 10 minutes to obtain proper clothing and return. The following rules apply:ħ All earbuds and headphones are forbidden in the lab.ĭuring warm weather, this policy becomes troublesome, but will be enforced. Clothing may have to be immediately removed if grossly contaminated with chemicals or ignited. Clothing should protect as much of the body as possible.

Clothing and Personal Items Students are urged to dress with potential lab hazards in mind. Students may wear one glove if transporting an empty container to the FOX stockroom when requesting a reagent refill. Students should not wear gloves outside the lab room, to the hallway or restroom. When wearing gloves, students should refrain from touching the computer keyboard or other surfaces another person without gloves is likely to touch. In general, students should wash their hands with soap and water at the completion of the lab period. The best safety practice is to be aware of any droplets of chemical solution that occur on the hands and immediately wash one's hands. Therefore, nitrile gloves are only provided for select experiments with concentrated acids/bases or toxic solutes. Hand Protection Many of the chemicals used in the general chemistry labs are dilute and pose little harm if a drop falls on the skin. These can range from point deductions to dismissal from the laboratory, depending on the severity or frequency of the offense. Refusal to wear eye protection will result in penalties. You must also sign a waiver stating that you understand the dangers involved and will not hold the university liable if they result in an injury. If you wear them, you must wear safety glasses as well. Wearing contact lenses in lab is strongly discouraged. This may require approval by the lab coordinator. If you have prescription safety glasses with side shields, or safety glasses from a job or other activity, you may wear them instead of the university-issued glasses. If you wear glasses, safety glasses must be worn over them. You must wear safety glasses at all times while in the laboratory. You will be issued a pair of safety glasses or goggles during check-in. For these reasons, eye protection is crucial in the laboratory. (Think about soapy water!) Of course, your eyes are more susceptible to major injury than other parts of your body. Getting a chemical in your eyes can be agonizing, even if it would cause no problem anywhere else on your body. Eye Protection In labs, there is the potential for spills and splashes of corrosive chemicals and explosions involving broken glass. Failure to comply with the rules will result in penalties that may involve being ejected from the lab and given an unexcused absence and a grade of zero for the experiment(s). The safety rules given below are meant to prevent accidents and to minimize injuries. The experiments you will perform are designed to minimize hazards, but dangerous materials are involved and accidents can happen. In any laboratory, safety is of paramount importance. The student is advised to consult this information frequently and to inquire about points that are not clear. It also indicates that the student will comply with these rules and regulations and any later additions to them.
