1 Process Fire - An unintended oxidation that occurs in a process area that produces flame or glowing embers, or evidence that this has occurred, such as charred or burned material.

Controlled Process Fire - The fire potential was anticipated and safeguards put in place to control/contain the fire should it occur, and the fire does not exceed the anticipated consequences, and there was no damage to equipment beyond the initiating failure, and there were no injuries to personnel resulting directly from the fire.

Uncontrolled Process Fire - Any process fire that cannot be classified as controlled.

2 Hazardous waste numbers are based on routine waste (wastes that are generated on-site on a regular basis as a result of normal plant operations and often tied to production rates).

3 Loss of Process Containment Incident: An unanticipated leak, spill or release of process material to the air, water, land or work environment that resulted or could have resulted in a process, safety or environmental incident

4 Production data includes the range of materials considered to be high value chemical (HVC) products. This includes the primary products and co-products for which chemical plant operation is generally optimized to produce, and these may be consumed in further processing or sold to third parties.
