You must: • Carefully read through the experiment to be performed.
• Look up information on equipment, materials and special techniques required for the experiment. • Complete your pre-lab assignment (if given one). • Print out hard copies of the experiment to be performed and the data sheet for the experiments. 2 STUDENT SAFETY AND EMERGENCY INFORMATION 2.1 Personal Protective Equipment (PPE) and Safe Attire 1.
Wear chemical safety goggles and a knee length (41-42 inch) laboratory white coat at all times while in the laboratory when anyone is conducting experiments. Wear closed shoes at all times while in the laboratory. Wear nitrile gloves when directed to do so by your instructor and/or lab manual. Confine long hair when in the laboratory so that it will not catch on fire or encounter chemicals.2 Behavioral Rules for Safety a.
Do not enter the laboratory until your lab instructor is present. Do not eat, drink, chew gum or smoke in the laboratory at any time. Keep all food and drinks sealed and, in your backpack, or purse. Consider all chemicals to be hazardous unless instructed otherwise.
Do not taste anything in the chemistry laboratory. Smell chemicals carefully and only when instructed to do so. Waft odors towards your nose rather than sniffing directly. Do not use flammable liquids near open flames.
Most organic liquids are flammable. Diethyl ether is especially dangerous. When heating substances in a test tube, never point the mouth of the test tube at yourself or at anyone else. It may erupt like a geyser.
Do not force glass tubing or thermometers into rubber stoppers. The tubing or thermometer may break and cut you badly. Consult with your laboratory instructor for assistance. Use caution when handling Bunsen burners, hot plates, and glassware or other equipment that has been heated.
Burns are the most common laboratory injury so treat all equipment as if it were hot during experiments that involve heating. Work with dangerous or volatile chemicals in a fume hood as directed by your instructor and/or lab manual. Do not perform unauthorized experiments. If you see someone else doing something you think may be dangerous, tell him or her to stop and/or report the PHUNG THANH KHOA 5 Downloaded by ANH BACH (bachvan15@gmail.com) lOMoARcPSD|39150642 International University Inorganic Chemistry Laboratory incident to your lab instructor.
If another student tells you to stop doing something because it is unsafe, stop as directed. Consult your lab instructor if there is a problem or difference of opinion. Notify your lab instructor immediately if you have an accident, spill, or are injured in any way. If chemicals encounter your skin or eyes, wash with water for at least 15 minutes.
Know where to find and how to use the eyewash stations in the lab. It is not recommended to wear contact lenses in the laboratory since chemicals splashed in the eye may get under the lens therefore be difficult to rinse. If a splash occurs while you are wearing contact lenses, they must be safely removed as quickly as possible. Know where to find and how to use the safety shower in the front of the room.
Clean up spilled chemicals immediately. Consult your laboratory instructor if you are not sure what to do. Solid sodium bicarbonate (baking soda) is available in the laboratories in containers located by the sinks. Use this to neutralize acid spills before wiping them up.
Similarly, solid citric acid solution is available in containers by the sinks and should be used to neutralize base spills before wiping them up. A saturated solution of sodium bicarbonate is also available by the sinks and can be used to wipe dried acid or base residue off lab benches as needed. However, if acid or base spills on your skin, do not waste time looking for these neutralizing substances. Rinse with water immediately for at least 15 minutes.4 Proper Waste Disposal Separate waste as follows: a.
Waste chemicals should be disposed of as directed by your lab instructor. Most chemicals are NOT to be thrown down the sink. Special waste receptacles will be provided for these chemicals. Waste chemicals must be sorted by kind, not just mixed with other, different waste chemicals.
Read waste container labels carefully. Notify your instructor when a waste bottle is nearly full. Do not overfill waste bottles. Broken glass is to be disposed of in the cardboard boxes labeled "Broken Glass Only" located near the doors to the lab.
A dustpan and broom are in each lab to assist you in cleaning up broken glass. Do not put broken glass in the regular trash, and do not put anything except broken glass in the broken glass containers! c. Gloves used in lab are to be disposed of in the containers labeled “Used Gloves Only” located next to the sinks in each lab. Other trash that is not glass and is not contaminated by hazardous chemicals should be placed in the large waste baskets near the front of the lab room.

Material Safety Data Sheets (MSDS) are available for all the chemicals used in this course. These sheets give information about the chemical, physical, and physiological properties of chemical substances. See your instructor for information about accessing these sheets.
A shortcut to MSDS websites is available on the site mention in the table of contents. They can also be found by entering the name of the chemical and MSDS into Google or any other search engine. Each laboratory experiment involves its own specific hazards. Be sure to read your laboratory procedure carefully before arriving for lab and take note of all safety precautions.
You are responsible for the information provided in the laboratory procedure. You must also arrive on time for all laboratory sessions so you will be present to hear the safety information provided by your lab instructor. For the safety of all students in the class, students who arrive late to lab will not be allowed to perform the lab experiment that day.6 Student Safety Training Record Department Chemistry Laboratory Student Safety Training Record Course: Semester: Year: Instructor: Date of Training: I certify that I have read the online available following documents from the Chemistry Department, and that I agree to abide by the policies therein: 1.

Laboratory Employees -- Each individual working in a laboratory should be informed about hazards associated with that laboratory and the specific work going on there.
This includes all faculty, laboratory staff and student workers. Support Personnel -- Storeroom, janitorial, maintenance, and delivery personnel may be exposed to potential physical and chemical hazards from work carried out in the laboratory. They must be informed about the risks involved and trained how to avoid potential hazards. Department Head, Faculty members, Lab instructors, Lab attendants shall: 1.
Work with administrators, faculty and laboratory staff to develop and implement appropriate chemical hygiene policies and practices. Monitor procurement and use of chemicals in the lab, determining that laboratory facilities and training levels are adequate for chemicals in use. Perform regular, formal chemical hygiene and housekeeping inspections that include inspections of emergency equipment. Maintain a current chemical inventory of chemicals present within the lab and stored room.
Review and improve the Chemical Hygiene Plan on, at a minimum, an annual basis. Maintain overall responsibility for the safe operation of the laboratories. Determine the proper level of personal protective equipment; ensure that such protective equipment is available and in working order. Ensure that the appropriate training has been provided to employees.
Monitor the waste disposal program.
