Following federal, state and city environmental rules, the removal of the lead-based paint is done in a sealed containment system under negative pressure.
Ramsey reported back in February 1944, proposing a small-scale test in which the explosion was limited in size by reducing the number of generations of chain reactions, and that it take place inside a sealed containment vessel from which the plutonium could be recovered.
FEBEX (Full-scale Engineered Barrier EXperiment) is a demonstration and research project dealing with the bentonite engineered barrier designed for sealing and containment of waste in a high level radioactive waste repository.

The overall radiation release from the plant is staggering – 770,000 terabecquerels in the wake of the accident and a billion becquerels still being added each day while engineers struggle to seal the broken containment structure.
Approximately one month after the initiating event, the reactor cores were stabilized, cracks in the foundations of the containment vessels were sealed, and irradiated cooling water began to be pumped to a storage building until it could be properly treated.
The virus was carried in the bloodstream of Doctor Kent Brantly, who travelled within an Aeromedical Biological Containment System — a hermetically sealed, transparent plastic tent that isolated the patient from the flight crew.
In principle, this should not cause leakage of radioactive material because the building is just an outside shell; the job of keeping dangerous materials sealed in falls to the the metal containment vessel inside.
Luisa describes an interview she did with Hitchcock (who, she says, described his own works as rollercoasters), in which she "put it to the great man, the key to fictitious terror is partition or containment: so long as the Bates Motel is sealed off from our world, we want to peer in, like at a scorpion enclosure.
The distinguishing feature is transfer of pumping power by alternating air flow across a containment barrier, inside which there are no moving, deformed, or sealed components.
In this study, we presented and applied a novel approach to evaluate the effects of permeability and porosity heterogeneities on the alteration of minerals, the associated evolution of the caprock sealing efficiency and the containment of supercritical CO2 (scCO2) within the caprock.
