 All lab users are required to complete OSU's online training modules for basic lab safety. You must go through this process before you are given keys to the lab. All lab users are required to complete OSU's online training modules for basic lab safety. You must go through this process before you are given keys to the lab.
-  * Go to the [[http://oregonstate.edu/ehs/training-materials|OSU EHS training materials]] +  * Ethan will add your name to the lab safety management tool (SciShield) which is administered by OSU's Environmental and Health Safety (EHS) Department.  
-  * Scroll down to "Laboratory and Chemical Safety" +  * SciShield will contact you will a list of training materials. This will include things like hazardous waste awareness, compressed gas safety, sharps safety, eyewash and safety showers and fume hood safety. 
-  * You will see list of required training modules (as of May 2019 the three required modules are "Lab Safety Training", "Safety Data Sheets & Haz Comm", and "Hazardous Waste") +  * Complete the online training modules. You'll be logged in with onid credentials and the SciShield system will record the trainings.
-  * Complete these online modules. Use your onid username/password to take the quiz or to acknowledge completion. +
-  * You will receive emails verifying completion of each module. Forward these emails to Ethan.+
  
-As a complement to the basic lab safety training, you must also complete this quiz which is specific to the Minot Lab: {{::chem_safety_quiz9.doc|}}. Make a hard copy (print out) of this safety quiz, fill in the answers, and give it to Ethan. Some of the answers are found on this wiki page. Scroll down to see information specific to the Minot Lab. +As a complement to the basic lab safety training, you must also complete this quiz which is specific to the Minot Lab: {{::chem_safety_quiz9.doc|}}. Fill out this quiz and email it to Ethan.

   *There is one fume hood for organic solvents (acetone, ethanol, IPA) and one fume hood for acids. Never bring the organic solvents into the acid hood. Never bring acids into the organic solvent hood. This absolute/unbreakable rule protects us from the risk of accidentally mixing an oxidizing agent (e.g. nitric acid, see [[http://www.youtube.com/watch?v=FXhE57b5ofw|video]]) with a hydrocarbon fuel (e.g. acetone or IPA).    *There is one fume hood for organic solvents (acetone, ethanol, IPA) and one fume hood for acids.

   *Take labeling very seriously. There should never be unlabeled liquid in the lab, even for a second. It is very hard to identify a chemical when it has been forgotten (it only take one distraction to mix up two beakers). This rule protects our devices, protects us from accidentally mixing the wrong chemicals and protects us from treating dangerous chemicals as if they were safe.   *Take labeling very seriously.

   *Before using a chemical for the first time, read the [[http://en.wikipedia.org/wiki/Material_safety_data_sheet|MSDS]]. In the lab there is a folder of MSDS sheets (they are shipped with the chemical, save the MSDS when you open a box!). If the MSDS is not in the lab folder, you must print a copy and add it to the folder (go to the manufacture website or try an [[http://www2.siri.org/msds/index.php|online database]]).    *Before using a chemical for the first time, read the [[http://en.wikipedia.org/wiki/Material_safety_data_sheet|MSDS]].

   *We use HF (hydrofluroic acid) in Weniger 306. HF is arguably the most dangerous acid used at the university. Anyone wanting to use HF or the acid hood needs additional training.

-Acetone, Ethanol and Isopropanol are all organic solvents. They are collected together in the [[plastic storage container]] labeled "organic waste". When this 5 gallon waste container fills up use the [[http://oregonstate.edu/ehs/forms|online form]] to request hazardous waste pickup. Do not dispose by evaporation (i.e. do not leave unsealed containers of solvent in the fume hood). +Acetone, Ethanol and Isopropanol are all organic solvents.

-Chlorinated solvents sometimes require special handling (they are more toxic). A small amount of DCE is allowed in the solvent waste container. Check the label of the solvent waste container to know the allowed fraction.
