II. Storage of Chemicals
- Copies of location guides for chemicals and for the 4 control areas are located near sink areas in the two prep rooms on the Chemistry floor.
- Flammable or compbustible chemicals must be stored in NFPA-30 flammable storage cabinets in the 4 control areas approved by the Memphis Fire Department. It is permissible to have up to 4 liters per 100 square feet in laboratories where these chemicals are in active use.
- Acids must be stored in cabinets designated for acids or corrosive materials. Nitric and sulfuric acids must not be stored with organic materials, including organic acids such as acetic acid. Acetic acid should be stored in HFPA-30 rated corrosion resistant storage cabinets.
- Strong bases shall be stored separatelyl from other reagents.
- Oxidizing and reducing agents shall be stored separately from other chemicals and from each other. They shall be stored on metal shelving in metal storage cabinets with locks. (Note: Acids that are also oxidizing agents are stored with the acids; but strong oxidizing acids must not be stored with organic acids.)
- Active metals will be stored on metal shelving separately from all other chemicals.
- Inorganic chemicals and axalates that present special health hazards and do not fall into one of the categories listed above will be stored in locked cabinets.
- Inorganic chemicals and/or salts that do not fall under one of the groups listed above will be stored together, but separately from other reagents.
- Organic chemicals that do not fall into noe of the groups listed above will be stored together, but separately from other reagents.
- All chemicals must be properly labeled. If you have any imporperly lab eled chemicals or chemicals without labels in your lab, contact the c hmical hygiene officer at once.
- MSDS sheets for each chemical must be present in the room in which the chemical is stored.
III. Student Laboratories - defined as laboratories in which labs listed on the Academic Schedule of Classes meet
- These labs must be kept clean and free of clutter. Only materials in current use should be out.
- At the end of each lab, students must put away all glassware in their drawers or other assigned locations and return reagents to their proper locations.
- Reagent bottles must be clean and properly labeled.
- Students must wear approved safety glasses and lab aprons at all times in the lab. (The requirement for lab aprons goes into effect August 15, 2009.)
- Hazardous waste must be collected in labeled bottles/containers; the label must specificially list each component that has been added to that bottle/container. The bottles/containers must be closed or capped after water addition has been made to them. Waste bottles/ containers must not be left open when the lab sessions are over. At the end of each lab, estimates must be made of the total amount of each component present in the bottles/containers; these estimates must be taped to the sides of the bottles/containers.
- Where posible, inorganic and organic chemicals should be collected separately.
- Chlorinated hydrocargons should be collected separatelyl from non-chlorinated hydrocarbons.
- Strong oxidizing agents should be collected in separate containers.
- Dilute solutions of low hazard acids and bases should be collected and disposed of as described below.
- Dilute low hazard acids and acidic solutions should be collected, and the pH adjusted before disposing down the drain. Records must be kept of the disposal process. Only solutions phaving a pH between 5.0 and 9.0 may be poured into a drain in a laboratory or preparation room.
- Dilute low hazard bases and basic solutions should be collected, and pH adjusted before disposing down the drain. Records must be kept of the disposal process. Only solutions having a pH between 5.0 and 9.0 may be poured into a drain in a laboratory or preparation room.
- Each student lab must have a fire blanket, safety shower, eye-wash station(s), fire extinguisher, and MSDS sheets for the chemicals used in or stored in the lab. At the first meeting in the laboratory room, the laboratory instructor must specifically point out the safety equipment to the students.
- Students in each lab course shall be informed of our Right-to-Know Policy and will be provided general information about MSDS sheets and how to interpret NFPA ratings. All of the chemicals used in each experiment shall be isted in the description of the experiment that is present in the lab manual or laboratory handout. When unknowns are used in an experiment, students shall be given a complete list of the unknown chemicals that are to be used during a lab session so that they may check the potential hazards associated with each chemical; this list of unknowns must be provided before or at the start of the lab session.
- MSDS sheets for each chemical used during the student labs shall be available in binders located within the lab.
- With the exception of brief restroom breaks, faculty must be present at all times either in the lab itself or the adjacent preparation room for all freshman and sophomore level laboratory courses. For junion and senior level labs, faculty must be neaby on the same floor as the lab; but a minimum of two peopel must be present at all times in all albs in which students are working.
- Broken, cracked, or chpped glass must be disposed of in the blue boxes labeled "Deposit Broken Glass Here" across the top. Faculty should check to make sure that all peices of glassware used by students are unbroken and free of cracks that may lead to accidents later on.
- Use of heat sources in the lab.
- Correct Bunsen burner use should be demonstrated early in each semester of the freshman labs. It should not be assumed the students remember all the rules for correct and safe usage. Bunsen burners should never be left unattended after being lit. Only Pyrex brand glass should be heated; wire gauze with ceramic pads should be used when heating beakers and flasks to ensure even heating and prevent cracks that can lead to the bottom half of the beaker or flask breaking off from the top half with possible injury to the student. Do not heat dry beakers or flasks.
- Hot plates should be monitored closely when heating beakers and flasks. Do not allow the contents of the beakers or flasks to evaporate to dryness while heating; this can lead to cracks that can lead to the bottom half of the beaker or flask breaking off from the top half with psosible injury to the student.
- Check heating mantles and not plates for frayed cords; do not allow students to use damaged equipment.
- Labs that use acids and bases should have baking soda present to use in case of spills.
- Student labs should have dispensers for hand soap.
- No unlabeled bottles or containers should be present in student labs.
- Windows in laboratory doors facing the hallway should be left uncovered for safety reasons. In the event you must cover a window because an experiment shuold be performed in darkness, you must post a sign outside the door stating: "The door is temporarily covered for experimental purposes" and take the covering down imediately after the experiment is finished. Failure to do this will be considered a violation of the chemical hygiene policy.
IV. Labeling of Chemicals
- All containers, without exception, must be labeled with the chemical components contained therein. Prepared solutions must also contain concentrations, date, last name of the person who prepared the solution, and special hazards associated with the solution. A
- lways leave chemicals in their containers, if possible.
- When chemicals are transferred from their original containers, the new container must contain the name(s) and formula(s) of the chemical(s), the NFPA rating for the chemical(s), and special hazards or precautions.
- Faded or damaged labels must be replaced immediately. Containers with unknown chemicals must be turned over the the chmical hygiene officer.
V. CBU Department of Chemistry Right To Know and Hazards Communication Policy
Into effect August 15, 2009.
All students and empoloyees have the right to have access to a listing of the chemical contents of all materials, substances, or mixtures they are asked to work with or may be exposed to while on the chemistry floors of Cooper-Wilson Center of Assisi Hall. They also have the right to immediate access in CW204 to the MSDS sheets for any of these chemicals.
When working with chemicals, students and workers have the right to refuse t use reagents with labels that have illegible names of the chemical contents or to use unknowns when they have not been provided with a complete listing of the possible unknowns to be used in the lab.
VI. Material Safety Data Sheets (MSDS)
Into effect August 15, 2009
