A Typical Week

At the end of Monday s safety meeting, Randy, the maintenance group s employee safety representative, announces that on Tuesday he will conduct a safety observation of the maintenance crew working on Unit 1. On Tuesday afternoon Randy gets Jim, another maintenance employee, and says, Come with me to Unit 1.1 want to do a safety observation of the crew there and would like you to come see how these are done so that you can do them later on. Your participation is totally voluntary, but it ll help us ensure a safe workplace.  

Jim agrees to go along. As they head for Unit 1, Randy and Jim discuss the fact that soon everyone in the plant, including the site manager and supervisors, will finish observation training and those who volunteer to do so will conduct safety observations. Everyone will be a partner in safety and share responsibility for achieving it. 

When Randy and Jim arrive at Unit 1, Randy takes a detailed, one-page checklist out of a folder. Without referring to the checklist, the two men first scan the work area. After Randy explains the procedure to Jim, they ask themselves, What do we see these employees doing that could cause someone to get hurt They note one such practice on the checklist. They further review the checklist, mark each safe practice, and check areas of concern. They do not record any names on the checklist.

However, since instruments like the ASI do cover a breadth of material, they are not likely to give you as many details about a specific problem area as you may want when working with a client. The questions on these interviews are somewhat limited for each domain and sometimes the details are not fully assessed by the limited questions. For example, consumption-pattern questions on the ASI ask how many days a person may use or whether the person has problems with a particular substance, but do not assess how much is used each day and when, or what a particular pattern of use may be during a typical week. 

Coal and nuclear facilities cannot be used in a cost effective way to provide peak power generation required by a typical weekly utility demand curve as shown in Figure 1. (3) Liquid and gaseous fuels meet this need now and will be used for this type of service over the next decade or more. Utilities have serious concerns about legislation preventing the use of domestic gas or imported oil to meet these requirements. This situation leaves the utilities between the proverbial "rock and a hard place."... 

Tn a typical week in 1973, the number of abstracts referring to enzymes listed in Biological Abstracts was over 60 less than 10% of that number appeared in Food Science and Technology Abstracts as actually or potentially significant in food. We estimate the enzyme industry to be about 25 million domestically and 100 million worldwide. Of this, food applications are about 15 million domestically and 45 million worldwide (in 1973).

Now you work on a weekly planner as an important tool for effective time management. You review the actual time spent on each of the following activities in a typical week. 

Toscano provided 1995 relative risk fatality statistics. Table 1.5 contains the 2012 data, which was the latest as this chapter was being prepared. Using the figures previously, during a typical week about 89 workers in the United States are killed on the job. Thank goodness that job-related fatalities are relatively infrequent for specific standard industry classifications (SIC code). A large incident in arty industry with multiple deaths will skew the information to reflect that tragedy in any year. 

Teaching of the course is conducted over a 12 week period with a typical week consisting of a one hour lecture followed by a one hour tutorial. In recent years... 

A typical weekly safety meeting could last about SOnainutes or until all of the safety-related discussions have been addressed and completed. Due to the nature of the meeting, it may require more time to discuss safety-related topics, new issues, injuries in other areas, facilities with similar exposures, or other changes in the organization. Other concerns can be put on the table such as squelching mmors about injuries that have occurred, status of hazard correction, etc. 

A TYPICAL WEEKLY MENU PLAN FOR SENIOR CITIZENS ... 

If one multiplies the number of tasks in a typical week by the number of children in an inclusive classroom who might need this kind of consideration, it is easy to appreciate why so many overworked classteachers are keen to claim that differentiation should be the responsibility of support staff (as revealed in chapter 2). 

The storage of chemicals, lubricants, aviation fuel and diesel fuel is normally on the platforms, with chemicals kept in bulk storage or in drums depending on the quantities. A typical diesel storage would be adequate to run back-up power generators for around a week, but the appropriate storage for each item would need to be specified in the FDR... 

When the closed vessel is heated to 390°C bottom and 330°C top, the resulting pressure is 170 MPa (25,000 psi) and a single fluid fills the vessel. It dissolves nutrient at the bottom and flows by convection, controlled by a baffle, to the upper region, where growth occurs at the lower temperature. A typical 4 cm x 152 cm x 1 mm thick seed plate grows to a 5-cm thickness in about 3 weeks in a 3-m long production vessel. 

Pumps are designed to give trouble-free operation for a long period of time. The ANSI B73.1M pumps are designed for a bearing life of no less than two years (29), and API 610 pumps for a minimum of five years (30). However, in real appHcations, a typical mean time between faUures (MTBF) is often found to be significantly less, and sometimes it is as short as a few weeks. Whereas in some instaUations the seals last from three to four years, in others these are replaced monthly. The reason for such wide variations in pump component life is often not poor pump design but equipment misappHcation. 

NAA cannot be used for some important elements, such as aluminum (in a Si or Si02 matrix) and boron. The radioactivity produced from silicon directly interferes with that ftom aluminum, while boron does not produce any radioisotope following neutron irradiation. (However, an in-beam neutron method known as neutron depth profiling C3J be used to obtain boron depth profiles in thin films. ) Another limitation of NAA is the long turn-around time necessary to complete the experiment. A typical survey measurement of all impurities in a sample may take 2-4 weeks. 

Base Metal Catalyst - An alternate to a noble metal catalyst is a base metal catalyst. A base metal catalyst can be deposited on a monolithic substrate or is available as a pellet. These pellets are normally extruded and hence are 100% catalyst rather than deposition on a substrate. A benefit of base metal extruded catalyst is that if any poisons are present in the process stream, a deposition of the poisons on the surface of the catalyst occurs. Depending on the type of contaminant, it can frequently be washed away with water. When it is washed, abraded, or atritted, the outer surface is removed and subsequently a new catalyst surface is exposed. Hence, the catalyst can be regenerated. Noble metal catalyst can also be regenerated but the process is more expensive. A noble metal catalyst, depending on the operation, will typically last 30,000 hours. As a rule of thumb, a single shift operation of 40 hours a week, 50 weeks a year results in a total of 2,000 hours per year. Hence, the catalyst might have a 15 year life expectancy. From a cost factor, a typical rule of thumb is that a catalyst might be 10%-15% of the overall capital cost of the equipment. 

Start to finish, a baseline PSM audit of a typical chemical plant can be conducted in a matter of one to two weeks using a team of about four auditors. 

Full site meetings may be held monthly or weekly, depending on the pace of the job. The main contractor or the project leader, who could be the architect or engineer, will chair a typical site meeting, and matters for the agenda will include ... 

A different design approach is used in this case. Instead of assuming an apparent modulus of elasticity using a constant creep situation covering the life of the chair, it is better to determine the actual creep deflection over a typical stress cycle, the creep recovery over a non-use cycle, and so on until the creep is determined after a series of what might be considered typical hard usage cycles for the chair. The accumulated creep after a period of two weeks can be assumed to represent the base line for an apparent modulus of elasticity to determine the design life of the chair. 

Wheat flour typically becomes white by means of normal oxidation in air during a few weeks of storage. To speed up the process, manufacturers use benzoyl peroxide as a bleaching agent. Sulfur dioxide is a reducing bleaching agent that is used to preserve dried fruits.
