Recall MSDS Sheet What is an MSDS sheet? Materials Safety Data Sheet Are they all the same set up? NO Do they contain similar information? YES 10/18/2015Property of CTE Joint Venture9

Recall MSDS Sheet cont. What do they contain, give at least five (5) examples? Name & trade name of the substance Hazardous ingredient(s) it contains Physical characteristics of the chemical Protective equipment to be used What to do in event of a leak or spill Any other precautions to be followed 10/18/2015Property of CTE Joint Venture10

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. 10/18/2015 Property of CTE Joint Venture11 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. 10/18/2015 Property of CTE Joint Venture12

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 school Level 2: Biological that may cause mild disease to humans. Not used in school Level 3: Biologicals that can cause severe to fatal disease to humans. Not used in schools 10/18/2015 Property of CTE Joint Venture13

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 10/18/2015Property of CTE Joint Venture14

What Should Be On a Chemical Label Stock 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 name Chemical formula Basic Chemical and Physical Properties Inventory barcode Purity 10/18/2015Property of CTE Joint Venture15

What Should Be On a Biological Label Stock Room Biologicals The identity of the material Storage requirements (refrigerate, Freeze -20˚C or -80 ˚C, etc) Biohazard level 10/18/2015Property of CTE Joint Venture16

Filling Out a Chemical Label for Storage Lets say you have prepared a chemical or solution and need to store it, now you need to make your own label for it. What you need to include: 10/18/2015Property of CTE Joint Venture17 Name of solution/ chemical Date prepared Concentration or strength MSDS diamond Prepared by
