In House Labeling

All secondary containers must be labeled.

Secondary container labels should have at least the following:
  1. Product Identifier
  2. Pictogram
  3. Signal Word
  4. Hazard Statement

Secondary container users should have immediate access to physical and health safety information that is on the Safety Data Sheet (SDS)

Example of Labeling a Secondary Container

Let's look at Labeling a secondary container of acetone.

First: We obtain hazard information on acetone from a Safety Data
         Sheet (SDS) or Manufacturer's Label   
  Identifier Acetone
  Signal Word
  Hazard Statement
  • Highly Flammable Liquid and Vapor
  • Causes mild skin irritation
  • Causes serious eye irritation
  • May cause damage to organs

Second: We use the highest hazard statement and corresponding
              pictogram for our new in house label

Third: Create the new Label

Secondary Container Label for an Acetone
Container used in a Lab or a Shop

1.  Identifier       --->

2.  Signal Word    --->

3.  Hazard Statement --->

4.  Pictogram    --->



Flammable Liquid

Finally: Precautionary Statement and Supplier information are not required on the secondary containers.

Smaller, immediate use containers such as beakers, test tubes, Erlenmeyer(s) that are at the control of one employee or researcher do not need to be labeled as long as they are emptied at the end of the day, shift, or research procedure.
