Chemical Labeling

• Minimum Label Information
• Identity
• Hazard warning
• Information source
• It is illegal to deface or remove chemical labels
  as long as the container still contains the
  chemical.
• You may add your own
• Types of Labels
• Manufactures
• NFPA (704 diamond problem made for firefighters
  wearing personal protective gear)
• Shipping
• Waste

Waste

• Pouring chemicals down the drain or evaporating
  in a fume hood is not always a good idea (even
  when the provider recommends this action).
• Always check local regulations and sewage
  treatment plant for capacity before disposing of
  anything down the drain.
• If your waste water is not treated, DO NOT POUR
  ANYTHING DOWN THE DRAIN, check with EPA.
• Public school laboratories are not licensed to
  treat waste.
• Write neutralization into lab procedure.

• What do I need to do to be prepared?
• What are the prudent practices, protective
  facilities, and productive equipment needed to
  minimize risk?
