Safeguards enclosing

If the initial reaction is allowed to proceed too rapidly, considerable pressure may be developed in the bottles. As a safeguard against explosions it is advisable to enclose the bottles in wire mesh shields. 

Containment uses a physical barrier to prevent an uncontrolled release of materials to the environment. The walls of a vessel or pipe serve as the primary containment barrier that encloses harmful materials. Redundant (secondary) containment serves as a safeguard if the primary barrier fails, and is considered a postrelease mitigation measure. Containment can take many forms, depending on factors such as the system or process to be contained, the risks involved with a release, and the cost benefit of the additional secondary containment. 

The most common agglomeration technology for the conversion of sodium cyanide into a safe product is briquetting with roller presses. Almond- or pillow-shaped compacts are made. The systems are completely enclosed, equipped with highly effective dust collection systems to safeguard the operators, and executed in stainless steel to keep corrosion in check. The discharge from the roller press is screened within the enclosed system, fines are recirculated internally to the briquetter feed bin, and dean product is immediately packed into sealed containers. 

The gassing of cold-box cores produces off-gases that need cleaning before emission into the atmosphere. In order to safeguard the working atmosphere, the core shooting machines are enclosed and cores are flushed with air to remove all the gas residues before the machine is opened up to take out the freshly made core. 

All belts, blades, shafts, gears, and other moving parts shall be fuUy enclosed or safeguarded so that the worker cannot accidentally come in contact with them. If... 

Minutes of 33d Reactor Safeguards Committee meeting, ACRS Files, W. Kenneth Davis to Price, with enclosed redraft of site criteria, 6 June 1961, in AEC-R 2/32 (8 June 1961), AEC/NRC. 

A significant early exception to government reservation siting was approved in 1952 for the sodium-cooled Submarine Intermediate Reactor Mark A, which was to be located at Knolls Atomic Power Laboratory (KAPL) only 19 miles (30.6 km) from Schenectady, NY. In response to Reactor Safeguards Committee concerns, the entire reactor facility was enclosed in a gas-tight...
