Definitions (Click To Expand):
- Members: Purdue students with an active project on ours Project Management System.
- Employees: Any employed student/staff of the Bechtel Center that works in a lab.
- SDS: Safety Data Sheet provided by the manufacturer of a chemical product.
- DTI (Designated Trained Individual): An employee designated to manage the documentary and training aspect of Hazard Communication Standard.
- Chemical Name: Refers to the name of the chemical as per the SDS.
- Signal Word: Single word to provide a general degree of hazard of a chemical. The 3 words used in the Center are Danger, Warning and NonHaz.
- GHS (Globally Harmonized System of Classification and Labelling of Chemicals): A standard set of pictograms to depict various hazards presented by a chemical.
- ISO 7010: An international standard set of pictograms for use with hazards and safety signs.
- 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.
- 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.
- Chemical: This phrase is used for all chemicals that are not excluded from OSHA Hazard Communication Standards in 29 CFR 1910.1200(b)(6).
- OSHA (Occupational Safety and Health Administration): A federal agency under the US Department of Labour.
- Primary Container: The container in which the manufacturer ships the chemical.
- Secondary Container: Any container other than the primary container that stores the chemical and is not used up immediately.
- Containers: These include primary and secondary containers.
- HWP (Hazardous Waste Pickup): Purdue Environmental Health and Safety department provides hazardous waste management services available to all members and employees.
- Right To: Information you are entitled to as part of our policy.
- OS1: Project Management System used to track projects, reservations and certifications.
