  8. ISO 7010: An international standard set of pictograms for use with hazards and safety signs.
  9. Hazard Statement: On a SDS this a set of standardized statements conveying the hazards of chemical. On a label this is a simplification of the SDS hazard statements.
  10. Controls: A set of actions taken to manage a hazard. These can take the form of Elimination, Substitution, Engineering Controls, Administrative Controls, PPE; these are in the order decreasing effectiveness.

  14. Secondary Container: Any container other than the primary container that stores the chemical and is not used up immediately.
  15. Containers: These include primary and secondary containers.
  16. HWP (Hazardous Waste Pickup): Purdue Environmental Health and Safety department provides hazardous waste management services available to all members and employees.
  17. Right To: Information you are entitled to as part of our policy.
