Laboratory Safety
• Safety is the responsibility of everyone and
everyone will be held accountable.
• Safety glasses are mandatory, no exceptions.
• Contacts should not be worn.
• Lab coats are mandatory.
• Absolutely no food or drinks.
• Several of the experiments involve chemicals
which are toxic and hazardous. It is important
that YOU know where all the safety apparatus
are.
• Know where the emergency exits are.
• Be familiar with the Departmental Safety
Manual.
• Know where the MSDS information is.
Pre - Labs
• Pre-labs are not mandatory but are
strongly recommended.
• All partners must be present.
• The laboratory is running two classes this
term with an enrollment of 112. Please
schedule accordingly as the 3rd year class
will be slow.
• Pre-lab times are posted on the class
website.
