Via venting

Improper venting to atmosphere, i.e. other than via vents with flame arresters or serubbers, or via a knoekout drum, or to the eoiieet flare systems.

Some epidemiologic studies have suggested an increase in the cancer rate in operating room personnel who have been exposed to trace concentrations of anesthetic agents. However, no study has demonstrated the existence of a cause-and-effect relationship between anesthetics and cancer. Many other factors might account for the questionably positive results seen after a careful review of epidemiologic data. Most operating room theaters remove trace concentrations of anesthetics released from anesthetic machines via vents to the outdoors.

Devulcanising rubber can result in products that have bad odours, and this has been addressed in this system by the use of a novel deodorisation process that involves the injection of high-pressure water into the extruder. Odour-producing compounds are trapped in the high-pressure water vapour and removed via vents. 

Elame Arrester A flame arrester is a device permeable to gas flow but impermeable to any flame. It quenches the flame and cools the products sufficiently to prevent reignition at arrester outlet. Arresters are used to prevent a flame propagating into the system from outside (such as via a tank vent) or one part of the system to another (such as through connected piping). 

Heavy vapour ean remain in empty vessels after draining out liquid and venting via the top with similar assoeiated hazards. 

Containment of explosion overpressure, i.e. by designing plant eapable of withstanding in exeess of the maximum explosion overpressure, or safe venting of forees, e.g. via blow-off panels, doors, membranes. 

Unloading or loading liquefied gas escapes should be limited to those vented via safety devices or authorized by the harbour master. Rate of transfer should ensure pipelines cool gradually lines should be vented safely at the end of the transfer.
