Contractor Management

CCPS RBPS Element 11: This Element ensures that contractor workers are vetted for their specialized services and can perform their work safely using facility standards.

Continuous Release

Emissions that are long in duration compared with the travel time (time for could to reach location of interest) or averaging or sampling time.

Continuous Reactors

Reactors that are characterized by a continuous flow of reactants into and a continuous flow of products from the reaction system (e.g., Plug Flow Reactor (PFR) and the Continuous Stirred Tank Reactor (CSTR)).

Continuous Improvement

Doing better as a result of regular, consistent efforts rather than episodic or step-wise changes, producing tangible positive improvements either in performance, efficiency, or both. Continuous improvement efforts usually involve a formal evaluation of the status of an activity or management...

Primary containment system, basic process control system, operating procedures and training, and other measures to Keep process materials and energies confined within the primary containment system and to Keep the process within safe design and operating limits, thus avoiding abnormal situations...

Conservation Vent Valve

A device designed to maintain pressure within preset limits in a liquid-containing vessel for the purpose of emissions reduction. It also provides protection against excessive pressure or vacuum.

Consequence Based Approach
