  • Clean up clutter
  • Clean up all spills
  • Do not store items in your work space
  • Organize materials so you are not reaching over glass, chemicals, heat
  • 2. Store chemicals properly
  • Must be labeled with name and hazards

Chemical Hygiene Working with Chemicals

  • 1. Using a chemical or performing a procedure
  • Read the label and Material Safety Data Sheet (MSDS)

(www.mtholyoke.edu/offices/srm/ehs/msdslinks.html)

  • Ask someone that has done it before
  • Make sure your work area is safe (heat source, flammables, etc.)
  • If it is dangerous notify someone in the lab before you begin
  • 2. Transport chemicals properly
  • Must use secondary containment
  • 4 L or less: use a bucket
  • Greater than 4 L: use secondary container and place on a cart
  • 3. Before you leave
  • Is your space tidy?
  • Is your reaction safe? (condensers secured, labeled, heat source)
  • Waste bottles closed? Hood sashes closed? Lights off?

  • Must determine if the student is adequately trained and experienced
  • Complete “Permission to Work Independently” form
  • 2. Students
  • Must perform all work in accordance with approved procedures
  • Have written permission from supervising faculty member

Lab Citizenship

  • No food in the lab
  • Keep the clean areas clean (no touching with gloves on, no chemicals, etc.)
  • Do not leave a mess
  • Do not use other’s glassware or borrow anything without asking first and

returning the items when you are finished

  • Instrument use:
  • leave name and phone number if need to leave the instrument
  • sign the logbook, contact person to fix it if not working properly
  • Inform others when doing something dangerous
  • make sure they know what could go wrong and what they are supposed to do

ASK IF YOU ARE UNSURE

slide-27
SLIDE 27

Lab Citizenship

  • Think before you heat:
  • do you really need to heat
  • how will you control the heat
  • how will you make sure it will not go dry
  • Gas cylinders:
  • you must be trained before you can use them
  • make sure they are strapped to the bench
  • when transporting or not in use, make sure safety cap is on
  • when transporting always strap to a cart

ASK IF YOU ARE UNSURE

slide-28
SLIDE 28

Hazardous Waste Management

  • Waste Containers:
  • make sure they are labeled with a hazardous waste label
  • make sure the information on the label is filled in correctly with the full written

name of all compounds (not a formula) and legible (e.g., Hydrochloric Acid, not HCl)

  • make sure to check all hazards (Flammable, Oxidizer, Corrosive, Toxic) that apply
  • you must add the contents to the manifest when you add it
  • you must keep the container capped when not in use
  • the container must be kept in secondary containment
  • clean up any spills (on the sides of the container)
  • E-mail Lori Smith (lbsmith@mtholyoke.edu) to remove full waste containers
  • Think before you add:
  • does it belong in this container?
  • is it chemically compatible with all compounds in the container?
  • will it react with any other compound in the container?
  • is there enough room in the container?
