Containment doors

Some door gaskets in furnaces, ovens, and wood and coal stoves may contain asbestos. The asbestos-containing door gaskets on wood and coal-buming stoves are subject to wear and can release asbestos fibers under normal use conditions. Handle the asbestos-containing material as little as possible. 

Rooms and/or cabinets for chemical storage must have limited student access and ventilation to the exterior of the building separate from the air-conditioning system. The rooms should be kept at moderate temperature, be well-illuminated, and contain doors lockable from the outside and operable at all times from the inside. Cabinet shelves must have a halfinch lip on the front and be constructed of non-corrosive material. 

Several researchers seek to design materials with high performance, greater efficiency, low costs, and lower overall automotive weight, resulting in reduced fuel consumption and CO2 emissions. Most car parts are composed of plastic composite materials. Chevrolet Impalas contain doors with thermoplastic polyolefin nanocomposite. General Motors and BaseU published the application of clay/polyolefin nanocomposites as a step assistant component for GMC Safari and Chevrolet Astro vans in 2001 [61-63]. 

Thermoforming is perhaps the process with the lowest unit cost. Examples of thermoformed articles are refrigerator-door and food-container liners, containers for dairy products, and luggage. Some of the largest formed parts are camper/trader covers and liners for refrigerated-radroad-car doors (236). 

Epoxy Resins. Epoxy resins (qv) or polyether resins are thermosets used as the binder for terrazzo dooring. The epoxy resin often is made from epichlorohydrin and bisphenol A. An excess of epichlorohydrin is used to assure that the intermediate product contains terminal epoxide groups. 

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. 

Secondary containment systems are best described as passive protective systems. They do not eliminate or prevent a spill or leak, but they can significantly moderate the impact without the need for any active device. Also, containment systems can be defeated by manual or active design features. For example, a dike may have a drain valve to remove rain water, and the valve could be left open. A door in a containment building could be left open. 

A radioactive source was transferred from one container to another by remote operation in a shielded cell. A radiation detector, interlocked with the cell door, prevented anyone from opening the cell door when radiation could be detected inside it. To make sure the interlock was working, an operator tried to open the cell door, by remote control, during a transfer. He found he could open it. He then found that the closing mechanism would not work. Fortunately he had not opened the door very far.

Articles made from polyacetals vary from door handles to gears and bushings, carburetor parts to aerosol containers. The major use of polyacetals is for molded grades. 

The balance must of course be protected from draughts and from dust, and the balance pan is situated within an enclosure provided with glass doors which can be opened to provide access to the pan. The remainder of the balance, including the electrical components, is contained in a closed compartment attached to the rear of the pan compartment. 

For the noble metals used in oxidation, the loading is about 0.1 oz per car, with calls for a million ounces per year. The current world production rates of platinum, palladium, and rhodium are 1.9, 1.6, and 0.076 million ounces respectively the current U,S. demand for platinum, palladium, rhodium, and ruthenium are 0.52, 0.72, 0.045, and 0.017 million ounces respectively (72, 73). The supply problem would double if NO reduction requires an equal amount of noble metal. Pollution conscious Japan has adopted a set of automobile emission rules that are the same as the U.S., and Western Europe may follow this creates a demand for new car catalysts approaching the U.S. total. The bulk of world production and potential new mines are in the Soviet Union and South Africa. The importation of these metals, assuming the current price of platinum at 155/oz and palladium at 78/oz, would pose a balance of payment problem. The recovery of platinum contained in spent catalysts delivered to the door of precious metal refiners should be above 95% the value of platinum in spent catalysts is greater than the value of lead in old batteries, and should provide a sufficient incentive for scavengers. 

Work areas were laid out in such a way that flammables would not be handled near either door. Upon arrival, cartons containing samples or supplies went where they would not interfere with traffic. Approved warning signs were posted where needed. 

Containment of explosion overpressure or safe venting of forces, e.g. via blow-off panels, doors. 

Dry heat sterilization is usually carried out in a hot air oven which comprises an insulated polished stainless steel chamber, with a usual capacity of up to 250 litres, surrounded by an outer case containing electric heaters located in positions to prevent cool spots developing inside the chamber. A fan is fitted to the rear of the oven to provide circulating air, thus ensuring more rapid equilibration of temperature. Shelves within the chamber are perforated to allow good air flow. Thermocouples can be used to monitor the temperature of both the oven air and articles contained within. A fixed temperature sensor connected to a chart recorder provides a permanent record of the sterilization cycle. Appropriate door-locking controls should be incorporated to prevent interruption of a sterilization cycle once begun. 

The NFPA code is represented in a diamond containing 4 sectors, respectively toxicity, inflammability, reactivity and special risks . A coloured code that will appear on glass labels, at the back of transport vehicles, room doors etc enables the danger to be better noted. It is used by American companies although some French companies have also adopted it and it appears to be an efficient device.
