Hazardous Substance Regulations

The Oregon Community Right to Know and Protection Act requires emergency service personnel who respond to an incident involving hazardous materials to file an incident report with the OSFM. The report must be received within ten (10) working days of the incident. For more information, please refer to the OSFM Incident Reporting Policy.

Extremely Hazardous Substances (EHS)
These substances are regulated by the Environmental Protection Agency (EPA).  Facilities that possess a Threshold Planning Quantity (TPQ) of an EHS are subject to federal emergency planning requirements.  TPQ’s are calculated based on the aggregate amount of an EHS substance at the facility at one time.  Facilities in Oregon are required to identify whether or not they are subject to these requirements on the Oregon Hazardous Substance Inventory Report.

For more information about EHS’s:

OSHA Hazard Classifications
Federal law requires facilities to identify the physical and health hazard classifications adopted by Occupational Safety and Health Administration’s (OSHA) Hazard Communication Standard. Facilities will report the hazard classifications for each reported hazardous substance as listed on the SDS. These classifications will be identified within CHS Manager and facilities will check the appropriate classification(s). These will include explosive, radioactive, poisonous and etiologic classifications which, if selected, will prevent the disclosure of the substance to the public.
