Chemical Hazard Label; The MSDS Diamond
With your partner quiz each other on what each of four (4) the sections of the
diamond tells us.
04/20/23 Property of CTE Joint Venture 11
Now complete the MSDS Diamond in your “Chemical and Biological Label and Labeling”
note-taker
Biological Hazard Label
This symbol tells us that the material is a biohazard and may represent a threat to cellular or living material.
04/20/23 Property of CTE Joint Venture 12
Biological Hazard Label cont.
There are three levels of Biohazards:Level 1: Minimal biohazards, personal protection limited to only gloves. What is worked with in schoolLevel 2: Biological that may cause mild disease to humans. Not used in schoolLevel 3: Biologicals that can cause severe to fatal disease to humans. Not used in schools

Why Have a Good Chemical/ Biological Label
You will go as a lab table group to your bench and list at least ten (10) reasons why you think it is important to have a label on chemicals/ biologicals and what you think should be included on the labels

What Should Be On a Chemical LabelStock Room Chemicals
OSHA mandates:The identity of the material The name and address of a responsible person
from whom information can be obtained if necessary Precautionary hazard warnings
Additional information:Common and IUPAC nameChemical formulaBasic Chemical and Physical PropertiesInventory barcodePurity

Labeling
Once you are finish you will be given a sheet of paper with chemical and biological sample data and blank labels.Fill them out as a group and turn in as your ticket out of class.
