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

04/20/23 Property of CTE Joint Venture 14

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
