Uncontrolled release

Dead legs in the sample line must be discharged safely to ensure that the sample will ac tuaUy be representative of the material in the unit. Without blowing down the dead leg, samples taken will be erroneous, as they may be representative of some past operating conditions. If the location is nonroutine, the sample leg may have accumulated debris. The debris could partially or totally block the line. Opening the isolation valve to blow down the line could result in a sudden, uncontrolled release, presenting a hazard to the sample gatherer. 

Uncontrolled release of flammable, toxic, or environmentally detrimental vapors from atmospheric vents.

Hazardous Materials Incident The uncontrolled release, or potential release, of a hazardous material from its container into the environment. 

Presynaptic a2-adrenoceptors function like sensors that enable norepinephrine concentration outside the axolemma to be monitored, thus regulating its release via a local feedback mechanism. When presynaptic a2-re-ceptors are stimulated, further release of norepinephrine is inhibited. Conversely, their blockade leads to uncontrolled release of norepinephrine with an overt enhancement of sympathetic effects at Pi-adrenoceptor-mediated myocardial neuroeffector junctions, resulting in tachycardia and tachyarrhythmia. 

Excavation of contaminated soils is required and may cause the uncontrolled release of volatile organic compounds, if they are present. 

SCWO may offer operation as a totally enclosed facility with no uncontrolled releases to the environment. 

Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) Law, also known as Superfund, passed in 1980 and amended by the Superfund Amendments and Reauthorization Act (SARA) of 1986 and later amendments, that governs federal response and compensation for unpermitted and uncontrolled releases, including threats of release, of hazardous substances to the environment. An unpermitted release is any release that is not properly regulated under other laws. An important focus of CERCLA/SARA is remediation of old, unpermitted waste disposal sites that are closed or inactive. Basic objectives of the Superfund program are to protect human health and the environment in a cost-effective manner, maintain this protection over time, and minimize the amounts of untreated waste in the environment.
