Chemistry 211  Organic Chemistry Laboratory I  Safety Introduction • Dress Appropriately (for chemistry lab) Proper attire is extremely important for your own protection. Accidents will happen in the lab; there is no way to prevent them, and that is why they are called accidents. Even if you are confident in your own abilities and believe that you would never spill something, you have to remember that other people are working around you every day. Wearing appropriate personal protection equipment (PPE) will help you to avoid the spills, bumps, and contact that will naturally result from lab work. DO NOT become the statistic that everyone talks about as a lesson for wearing PPE. Remind yourself of these important rules:  Long hair must be tied back.  Safety Goggles must be worn at all times!  Fully cover your chest, back, and shoulders. o No bare mid-sections or loose fitting sleeves.  ALL “bottom” apparel must extend at least to the knee.  Feet - Shoes must fully enclose the feet; o Closed Toe o Closed Sides o Closed Heel o Closed Top • Wear this Personal Protection Equipment At All Times in the lab! Yes, it is difficult to remember to wear PPE, especially since it is new to you, but it is extremely important to insure your well-being. You want to keep your eyes, you do not want to be scarred by flames or corrosive solvents. We all understand the awkwardness of wearing goggles, gloves and aprons but it is something that you need to do; you will learn to love the protection they provide.  Goggles – To protect your eyes.  Splash goggles with side vents protect a good portion of your face. Your neighbor might not mean to trip and spill concentrated NaOH in your face, but if you are wearing splash goggles your eyes will be protected. Get into the lab shower, and DO NOT remove the goggles.  Aprons or Labcoats – To protect your body.  If you are wearing appropriate laboratory attire, the apron is just adding a little additional coverage (and protecting your clothing). Aprons do not cover everything; your backside and shoulders are most vulnerable. Also, wearing cotton fibers (non-synthetic materials) will also give added protection because nylon, spandex and rayon will melt or burn when in contact with harsh chemicals.  Gloves – To protect your hands. Chemistry 211  Organic Chemistry Laboratory I   Nitrile gloves are supplied for everyone, but they are not invincible. If they are compromised (i.e. solvents have spilled on them or you have torn them), replace immediately. Once you have put on your gloves, be sure not to touch ANYTHING that you would not want chemicals on: your face, hair, clothes, doorknobs and public areas. Be sure to remove PPE before exiting the labs. Remember, the halls are public! Identify the Safety Equipment! On the first day of lab, you completed a scavenger hunt. Be sure to make a mental map of the locations for these safety devices: Fire Extinguisher Eyewash Safety Shower Emergency Exit • NEVER Eat or Drink in Lab Labs might seem like normal classrooms, but they are not! Food and drinks are NOT permitted in labs. Some chemicals can be fatal if absorbed through the ali
