Chem 1LC All Labs Marganet phyle complete notebook

A chemistry laboratory is an inherently dangerous place. Fire, toxic vapors, explosions, poisonous substances, broken glass, and corrosive materials are among the more common dangers. All of these hazards are aggravated by careless or thoughtless work. The main objective of this document is to encourage an attitude that will prevent accidents in the general chemistry laboratory. The following guidelines must be read and followed at all times to minimize the chances of accidents.You will be asked to leave the laboratory without finishing your experiment if you fail to comply with any of the following rules. These guidelines are derived from simple common sense. Naturally, the sheer complexity of any chemical laboratory will always present potential problems that cannot be anticipated in advance. The guidelines given here are therefore not all-inclusive (nor can they ever be). 1. Approved eye protection (shatterproof goggles) must be worn at all times in the laboratory.No exceptions! Contact lenses must be avoided whenever possible because corrosive materials and/or chemical vapors can be trapped between the lens and cornea where the chemicals may not be rinsed away, even during intensive washing. 2. Lab aprons must be worn at all times in the laboratory. The apron’s strings must be tied behind the student’s back so the lab apron is pulled in about the waist. 3. Proper gloves should only be worn when handling concentrated or toxic chemicals. The lab manual will specifically indicate when gloves are necessary. While wearing gloves, touch only the chemicals and glassware needed to perform procedural steps. Do NOT handle objects commonly used without gloves (such as computers, sink handles, door knobs, etc). You do not want to contaminate these surfaces, as you will eventually have to touch them once the gloves are removed. 4. Computer key boards must be covered with plastic wrap to avoid contamination. 5. Shorts, mini-skirts, and open-toed shoesare NOT permitted in the lab. Other loose articles of attire (e.g., long scarves) are not to be worn in lab because they can become entangled with equipment or prevent prompt emergency evacuation from a dangerous area. Long hair should be pinned back to prevent contact with flames or chemical reagents. 6. Emergency equipment is located in the lab room and hall areas. Note the location of eyewash fountains, showers, fire extinguishers, fire blankets, and spill clean-up buckets. If safety equipment is to be used call the TA and stockroom personnel for help. Note the location of emergency exit routes. 7. Fume hoods must be used for all reactions using (or evolving) noxious or highly combustible chemicals. If you are ever instructed to check a chemical odor, carefully WAFT the fumes to you with a small movement of your hand. Do NOT inhale deeply. Never test a chemical odor unless instructed to do so! 8. Spills must be contained and removed immediately. Spill clean-up buckets containing absorbent materials are located in the front of the lab room near the blackboards. Work areas (including balances, instruments, desktops, hood areas, etc.) should be cleaned after each use to remove any chemical residues. 9. Eating, drinking, and smoking are strictly forbidden in the laboratory. This includes chewing gum!When pipetting liquids, always use a pipet bulb; never pipet liquids by mouth! 10. Always wash hands before leaving the lab to avoid absorption or accidental swallowing of trace harmful materials. 11. Unsupervised experimentation is not permitted under any circumstance. An instructor must be present in the lab at all times when students are working. No horseplay or pranks are allowed. 12. No changes in written experimental proceduresare allowed without specific authorization of the instructor. Violation of these rules will lead to immediate disciplinary action. 13. Clean up: collection bottles are located in the fumehoods. READ THE LABELS ON THE COLLECTION BOTTLES and use the container ONLY for the chemicals indicated. NEVER put acids, bases, or oxidizing/reducing agents into the organic disposal containers - doing so may catalyze violent reactions. Never dump a chemical down the sink.Your complete cooperation will help maintain the quality of our water system. When in doubt, ask the instructor or stockroom personnel. 14. Read the labels on the reagent bottle. Verify that the formula of the chemical is the one you need for your experiment. Note the concentration, if a liquid. Check bottles for warnings specific to the particular chemicals in use. NOTE CAREFULLY! The absence of a warning label should never be misconstrued as an identification of the absence of dangerous properties. Safety and toxicity information about chemicals used in your experiments can be found by looking up the "Safety Data Sheet" (SDS). 15. Hot objects should be handled with extreme care. Allow to cool and handle with tongs or lined, heat-resistant gloves. Prep for Quarter/TA Office Hours 8 of 9116. When heating liquids in test tubes, use a clamp to hold the tube. Heat the liquid gently on the side of the tube near the liquid level,pointing the tube away from you and your fellow lab workers. Clamp the tube so it suspended in a water bath when heated to avoid hot spots and prevent violent boiling that could occur if the test tube is resting at the bottom of the water bath next to the hotplate. 17. Never add water to a concentrated acid!The reaction is very exothermic and spattering can occur. The ejected liquid may consist mostly of concentrated acid. When dilution of an acid is called for, ALWAYS add the acid SLOWLY to water and stir. Cool the container in an ice bath, if necessary. 18. All chemicals must be stored in LABELLED CONTAINERS. The label should contain the compound name, amount or concentration, the students' name, your name (as the TA), and date. 19. Extraneous materials in the laboratory (e.g., books, coats, etc.) clutter the working areas and create unsafe conditions. Place these items on a shelf or hook, out of harm's way. 20. Cracked or broken glassware should NEVER be heated, pressurized, or subjected to vacuum, regardless of how small the imperfection may appear. Broken glassware should be returned to the stockroom for repair or proper disposal. 21. Electrical equipment provides a possible cause of electrocution. Sparking from frayed or broken cords also may cause ignition of solvents. Report such hazards to the instructor and stockroom personnel and do NOT use the equipment in this condition. REMEMBER: You are responsible for your own personal safety in the laboratory and the TA and stockroom will enforce safety practices to create an overall safe working environment for everyone. The primary cause of accidents in laboratories is a lack of forethought. Be aware of other students' activities, because his or her carelessness could lead to your affliction. If anything in the lab looks precarious or suggests that something might be wrong, take immediate action and notify the instructor or stockroom personnel. There are no stupid questions when it comes to lab safety. However complicated these guidelines may seem, YOU are a major controlling factor. If you take the time to familiarize yourself with the experiments and proper laboratory procedures BEFORE you enter the lab, most of the potential for accidents will be eliminated. IF AN ACCIDENT SHOULD OCCUR... If an accident should happen, take immediate action, with the involvement of stockroom personnel or other TAs, if necessary. Call 911. FIRE If someone's clothing should catch fire, the standard technique to extinguish flames is "STOP-DROP-ROLL". NEVER run to a fire blanket or shower - you must immediately drop and roll to smother the flames. Running increases the flow of oxygen and increases the burn rate. If a fire should occur in the laboratory, fire extinguishers are in each corner of the lab room -know their locations. If the building fire alarm should sound, turn off hot plates and all other electrical devices. Ensure the equipment is in a safe and secure mode. Leave the building by the nearest stairwell exit. Do not use the elevators. Remain in a group with your TA outside away from the building and do not re-enter the building without the proper authorization. EARTHQUAKE Stay calm. Make sure your work area is safe. Secure chemical bottles, if possible. Protect yourself from falling debris such as plaster, pipes, light fixtures, etc. Turn off all electrical devices once the shaking stops. Do not exit the building unless the building itself becomes too dangerous to occupybecause considerable danger can exist at the outside doorways from falling glass and masonry dislodged by shaking. Remain in a group with your TA. CHEMICAL SPILLS If a chemical splashes in your eyes, immediately flush your eyes with cold, clear water for at least 15 minutes. An eye wash fountain is near the door in each one of the labs. Push the lever forward to deliver a steady, gentle stream of water into the eyes. Be sure to pull back the eyelid and roll back the eye to flush the affected area completely. If the chemical splash occurs while you are wearing goggles and the eyes are unaffected, flush your facewithout removing the goggles. The eyes can become contaminated as one tries to remove un-rinsed goggles. After the goggles are cleaned, rinse the eyes as instructed above. If the eyes are already affected, immediately remove goggles and begin flushing the eyes as described above. If harmful chemicals are spilled on clothes, remove the clothes and use the safety shower in the hall to rinse affected skin areas. The threads in cloth can act as small capillary tubes and quickly spread the chemical over a large portion of your body. Some chemicals may need to be neutralized or may be absorbed through the skin. Seek further treatment if necessary. Acids and bases are particularly hazardous materials because they are so corrosive. They can cause serious burns to skin and eyes. If splashed on skin or eyes, flush the affected area for at least 15 - 20 minutes with cold water. If diluting a concentrated acid, always add the acid slowly to a large amount of water with stirring, to avoid splattering. BURNS Small burns from touching hot objects should be flushed with cold water for 20 minutes. Do not apply ointment to burns. Major burns need immediate medical attention. Get the stockroom involved and call 911. CUTS Small cuts should be rinsed thoroughly and examined for traces of foreign materials such as glass, chemicals, etc. Bandages are available in the stockroom. Severe cuts and bleeding must be treated by applying direct pressure on the wound to control the rate of bleeding. Seek medical assistance immediately. Get the stockroom involved and call 911. REPORTING ACCIDENTS Use the phone in the stockroom or your cell phone and call 911 for the UCI police. After reporting the problem, send students to every exit in the building to meet the police and direct them to the location of the accident. Fill out a brief "Incident Report". Reporting an accident will not affect your grade! Please be cognizant of potential hazards BEFORE a serious accident occurs. UCI Professor Bill Evans in a Safety Shower Prep for Quarter/TA Office Hours 9 of 91Kim Edwards Jan 20, 2016 @10:19 AM PST Kim Edwards Jan 15, 2016 @10:12 AM PST SAFETY EQUIPMENT 1. Fire extinguishers are located by each door of the lab. Be sure to note the location of the extinguishers in your lab. 2. Sodium bicarbonate and Solusorb are located in buckets in the front of the lab and are used to neutralize/absorb chemical spills on the floor or lab tables. A 5-gallon universal spill kits is also available for larger spills. 3. The safety shower is located in the hall. Pull on the ring and chain to operate the shower. Use the shower to wash serious chemical spills on clothing and skin. Horseplay in the vicinity of the showers will not be tolerated - false alarms by pulling the chain may correspond to thousands of dollars in damage to office or lab materials on lower floors. 4. An eyewash station is located next to one of the laboratory doors. The eyewash operates by pushing the lever forward. Two gentle streams of water are directed upwards. For more effective washing, hold back the eyelids and rotates the eyeball to remove all chemicals. Be sure the student is not wearing contact lenses. 5. Fire blankets are located in a thin, vertical container in the hall between the laboratory doors. Insert arms into the loops hanging out of the cabinet and rotate to wrap the blanket around you. The blanket will smother flames on clothing. 6. Use your cell phone or the stockroom phone to call911. After calling, students NOT AFFECTED by the emergency should station themselves at the building entrances and loading dock so they can direct emergency teams to the scene of the accident. 7. Red fire pull alarm boxes are located on every floor near the stairs and elevators, on the wall at eye leve.l 8. First-aid kits are located in the stockroom
