1. The prevention of the release of unacceptable quantities of radioactive material into the environment by enclosing it tightly. 2. The containing system that provides the function of containment
Safe methods for managing infectious agents in the laboratory environment where they are being handled or maintained. The purpose of containment is to reduce or eliminate exposure of laboratory workers, other persons and the environment to potentially hazardous agents.
The structures, within and including the reactor building, designed to prevent any material that may escape from a nuclear reactor from reaching the outside environment. The reactor containment usually employs steel and thick concrete.
The retention of wastes in a manner that effectively prevents their release or dispersal into the environment in unacceptable quantities or concentrations.
A containment is an enclosure used as a barrier to prevent contamination from spreading to the environment and to prevent human exposure.
The gas-tight shell or other enclosure around a reactor to confine fission products that otherwise might be released to the atmosphere in the event of an accident.
application of phytosanitary [or other] measures in and around an infested area to prevent spread of a pest or a disease [FAO bis
Prevention of agent transmission from one point to another (primary, secondary, absolute, partial, total).
(physics) a system designed to prevent the accidental release of radioactive material from a reactor
quarantine; act of preventing the release of organisms under quarantine
The process of enclosing or containing hazardous substances in a structure, typically in ponds and lagoons, to prevent the migration of contaminants into the environment.
The process of keeping hazardous or radioactive wastes confined to a particular location, to prevent their accidental release into the surrounding environment.
a work area isolated from the rest of the building to prevent escape of asbestos fibers.
A process whereby RF energy is prevented from exiting an enclosure, generally by shielding a product within a metal enclosure (Faraday cage or Gaussian structure) or by using a plastic housing with an RF conductive coating. Reciprocally, we can also speak of containment as preventing RF energy from entering the enclosure.
A remediation method that seals off all possible exposure pathways between a hazardous disposal site and the environment, which generally includes capping and institutional controls.
A strategy used by police to confine the homeless problem to one area of a community to both minimize disorder and keep homeless people out of public view.
An approval category where a new organism or hazardous substance is restricted to a secure location or facility to prevent escape. This includes, in respect of genetically modified organisms, field testing and large-scale fermentation.
The structure that encloses the reactor, designed to prevent the escape of radiation from the reactor to the outside environment. Some reactors of the former Soviet Union (i.e. Chernobyl) do not have containment structures. The containment structure consists of layers of steel and reinforced concrete.
Containment means restricting an organism or substance to a secure location or facility to prevent escape; and includes, in respect of genetically modified organisms, field testing and large scale fermentation.
Glass used in guarding situations designed to withstand specified loads and prevent people from falling.
Methods or physical structures designed to prevent the dispersion of radioactive substances.
a container, vessel, barrier, or structure; whether natural or constructed; that confines a substance within a defined boundary.
those aspects of the social bond which act to prevent individuals from committing crimes and keep them from engaging in deviance.
A method of protecting both workers and the environment by controlling exposures to the dust and debris from hazardous materials such as lead created during abatement.
An isolation system designed to effectively contain asbestos fibre within a designated work area where asbestos-containing material is handled, removed, encapsulated or enclosed, and includes a glove bag.
