Safety plates

At about 0 40 p.m. on July 10, 1976, at a chemical plant in northern Italy, a safety plate of a reactor fractured, blowing the leaking substance into the sky as a white cloud. The cloud was carried on the wind toward the town of Seveso and was conveyed to the ground there by falling rain. The substance leaked contained the highly toxic material...

Two magnetically coupled safety plates, worth about 45 g of uranium, which by falling in 0.01 sec caused the reactor temperature to be lowered from 250°C to approximately 243°C. 

The entire x-ray exposure cabinet including it s extension into the lower electrical cabinet is shielded with a minimum of one-inch of steel clad, lead plate with fiilly welded (fused lead) joints. The safety interlock switch on the cam-lock inter-face ... 

The technique of the filtration of hot solutions has already been described in Section 11,28. The filtration of cold solutions will now be considered this operation is usually carried out when it is desired to separate a crystalline solid from the mother liquor in which it is suspended. When substantial quantities of a solid are to be handled, a Buchner funnel of convenient size is employed. The ordinary Buchner fimnel (Fig. 11,1, 7, a) consists of a cylindrical porcelain funnel carrying a fixed, flat, perforated porcelain plate. It is fitted by means of a rubber stopper or a good cork into the neck of a thick-walled filtering flask (also termed filter flask, Buchner flask or suction flask) (Fig. 11,1, 7, c), which is connected by means of thick-walled rubber tubing (rubber pressure tubing) to a similar flask or safety bottle, and the latter is attached by rubber pressure tubing to a filter pump the safety bottle or trap is essential since a sudden fall in water pressure may result in the water sucking back. The use of suction renders rapid filtration possihle... 

The advantages of electroless nickel over hard chromium include safety of use, ease of waste treatment, plating rates of as much as 40 p.m/h, low porosity films, and the ability to uniformly coat any geometric shape without burning or using special anodes. Increased chemical safety is another... 

Nondestructive testing of both the plate and the finished vessel is important to safety. In the analysis of fracture hazards, it is important to know the size or the flaws that may be present in the completed ves-... 

The maximum pressure from an explosion of a hydrocarbon and air is 7 x initial pressure, unless it occurs in a long pipe where a standing wave can be set up. It may be cheaper to design some small vessels to withstand an explosion than to provide a safety relief system. It is typical to specify %" as minimum plate thickness (for carbon steel only).
