Designated areas

Skiving is a variant in which the base metal surface oxides are mechanically removed foUowed immediately by pressure rolling of a precious metal or alloy strip. This is commonly used for inlays for electrical contacts and for jewelry fabrication. The common inlay materials include gold, silver, copper, brass, and solder. No heat is needed, and the coating is appHed only to designated areas so there is Htde waste (3,50). 

The following may be a few such design areas that may be considered, in improving the performance of a iriachine during an earthquake ... 

Handle in the most dilute form possible in elearly designated areas, away from potential ignition sourees. 

Limit access to designated areas to classified persons (e.g. in UK persons likely to receive doses in excess of 6 mSv per year or an equivalent dose which exceeds 30% of relevant hygiene standard). Access may need to be limited by trapped keys or interlocks for high dose rate enclosures. 

Prepare as appropriate written rules for work in designated areas and appoint Radiation Protection Supervisors. 

Control over chemicals, containers etc. removal from site (see also waste disposal) Prohibition of eating/drinking except in designated areas... 

Does the SAHP establish proeedures for eutting and welding in other than speeifieally designated areas, based on the fire potentials of plant faeilities [OSHA Referenee. 252(aX2)(xiiiXA)]... 

In those instanees when objeets to be eut or welded are moveable and the faeility has an area speeifleally designated for eutting and welding, are objeets taken to the designated area before hot work operations are performed [OSHA Referenee, 252(a)(2)(xiii)(A)]... 

Provide designated areas or bins for product waiting inspection. 

Provide separate designated areas for holding product awaiting inspection, passed inspection, and failed inspection. 

How many organizations do what we could really call direct rational solution of the composite structure design problem — very, very few. Perhaps only in some very restricted design areas do people feel that they can use a mathematically oriented optimization approach. That situation is unfortunate, but changing. 

Another common mistake often uncovered is electrical equipment w hich is not consistent with the design area classification. See Chapter 17. 

A similar checklist can be prepared for die other areas of interest mentioned above. Although die results of a checklist study are qualitative, these results can be used to idendfy design areas diat require furdier liazard evaluation and to communicate die safety needs of the plant to the management. 

Table 17.2.1 lists tlie major organizations providing tliese documents. Table 17.2.2 is a cross-reference to tlie same information listing tlie design areas. An extremely useful and detailed description of these organizations is provided by Burklin. ... 

In some instances, special terms may be applied. For example, where the insurance company requires the installation of an intmder alarm, the protected premises must be attended unless the alarm is put into full operation. In other cases, cover under the policy may apply only when the property insured is left within agreed and designated areas. 

Local authorities are empowered by the Control of Pollution Act 1974 to designate areas as noise-abatement zones. Within these areas noise levels are measured and entered into a register. It is an offence to increase noise levels beyond register levels unless consent is obtained. If the local authorities are of the opinion that existing noise levels are too high, noise-reduction notices can be served. 

In structural applications for plastics, which generally include those in which the product has to resist substantial static and/or dynamic loads, it may appear that one of the problem design areas for many plastics is their low modulus of elasticity. The moduli of unfilled plastics are usually under 1 x 106 psi (6.9 x 103 MPa) as compared to materials such as metals and ceramics where the range is usually 10 to 40 x 106 psi (6.9 to 28 x 104 MPa). However with reinforced plastics (RPs) the high moduli of metals are reached and even surpassed as summarized in Fig. 2-6. 

Areas for handling toxic or flammables should be segregated. A chemical like acetone, for example, should never be handled in the vicinity of an open heat source. Work wth highly toxic materials should be strictly confined to designated areas. Many operations must be performed in fume hoods. For others, only improved ventilation may be required. 

Food in most cases should not be in the laboratory, not even candy bars. There is always a chance that food products could become contaminated by chemicals on the work bench or on unwashed hands. There should be designated areas where food can be consumed. 

Limit access to designated areas to classified persons (e.g. in UK persons likely to receive doses of 30% of relevant hygiene standard). 

Establish procedures requiring that materials and equipment be placed in or returned to their designated areas... 

Any process which is a consequence of discrete tasks that have to follow a predefined sequence from raw materials to final products is a batch process. This predefined sequence is commonly known as a recipe. The primary features of any comprehensive recipe are the quantities of materials that have to be processed by individual tasks as well as the duration of each task within the recipe. The secondary features are the operating conditions of the various tasks, and in less common circumstances, the locality or geographic position of the task at hand. In processes wherein safety is of great concern, it might be necessary to perform a particular task in a designated area equipped with relevant safety features.
