Referring to Fig. VII-2, assume the surface tension of (10) type planes to be 400 ergs/cm. (a) For what surface tension value of (11) type planes should the stable crystal habit just be that of Fig. Vll-2a and (b) for what surface tension value of (11) type planes should the stable crystal habit be just that of Fig. VII-2i> Explain your work. 

A measure of sophistication is necessary in order to obtain a reasonable set of parameters. The following steps are recommended in order to address the concerns above. They are ranked approximately best to worst, but it is advisable to use all techniques for the sake of doublechecking your work. Step 9 should... 

Finally, we cannot end a chapter on the basic tools of analytical chemistry without mentioning the laboratory notebook. Your laboratory notebook is your most important tool when working in the lab, providing a complete record of all your work. If kept properly, you should be able to look back at your laboratory notebook several years from now and reconstruct the experiments on which you worked. 

All data should be examined before use, otherwise you may inadvertently introduce errors into your work. The standard does not require that data controls be the same as document controls so you are at liberty to pitch the degree of control appropriate to the consequences of failure. 

In the course of your work to date, you have identified your company s management style in different divisions, regions, and locations. If this style favors centralized management, a companywide PSM implementation strategy may be highly effective. 

In the immediate term, however, your plan may be most effective if you focus on the specific needs and priorities you have identified in the course of your work so far. If you clearly define the scope of your plan, and it directly addresses specific needs, your efforts will be far more successful than if you try to do all things for all people. Moreover, focusing on priority needs will almost certainly provide a sound basis for expansion or adaptation for example, procedures developed to address training for operators using high-hazaid materials at one facility (see Rextown vs. Effingham in Figure 5-2) should be readily adaptable to lower-hazard substances at another facility— far more so than the other way around. 

Your work up to this point has created the framework for a detailed plan. By following the process outlined in previous sections, you should have gained a clear understanding of ... 

Putting the PSM systems you have developed into actual practice provides the trae test of all your work to date. If you have "front-loaded" the development by devoting careful attention to detailed planning, you have helped close the gap between theory and practice. To maximize the value of that upfront investment, it s wise to devote the same care to initial installation. 

Measuring and monitoring PSM installation helps assure consistency and quality control in addition, effective monitoring helps keep local expenditures and schedules on track. In effect, these activities protect the investment you, your team, and your company have made in the course of your work so fac and for this reason they warrant continuing attention. 

Your company s PSM team is uniquely qualified to take on this role by virtue of your work so far you and your teammates have probably become your company s resident experts in PSM. At least as important during this phase, you also have developed a clear understanding of what s required for successful installation and ongoing implementation. 

Experience indicates that in a typical company there will be considerable overlap between and within the PSM and ESH and quality management systems. Your work to secure support (Chapter 2) will have already demonstrated many of these overlaps. The detailed assessment of the existing management systems described in this chapter will provide a comprehensive understanding of the overlaps.

Know what hazardous chemicals are used in your work area. 

You have had opportunities to ask many Why questions already from your work in the laboratory. In fact, there are enough such questions to provide the basis for the rest of the course. Some of the questions that have been raised in your experiments are listed at the end of the chapter. Can you add to this list How many of the questions can you answer now We will find the answers to many of them in our subsequent study. Some may not yet have satisfactory answers. These are the most interesting questions because they point into the future— your future. 

The rules of thumb discussed below have served this author well over the years. Depending on the nature of your work and data, your experiences may lead you to modify these rules to suit the particulars of your applications. But they should give you a good place to start. 

The first step in our journey is to realize that there is nothing so unusual about these factor-based techniques. In fact, it is likely that you have already used one or more factor spaces in your studies or your work without even realizing it You see, a factor space is nothing more than a particular coordinate system that offers certain advantages to the task at hand. When we operate in a factor space, instead of the native data space, we are simply mapping our data... 

The rate law for the reaction is Rate = [N2][H2J2. Which step is the slow step Show your work. 

You must assess risks to the health and safety of anyone who may be affected by your work activities, so that you can weigh up whether you have done enough or need to do more to comply with the law -see Management of Health and Safety at Work Regulations 1999. 

You may wish to use your works committee or another meeting as a forum for consultation. 

These are Just some examples of key areas this is not an exhaustive list. Look around your workplace to identify other risk areas. If any risks apply to your work activities, you will need to do risk assessments to check that you have removed or reduced the risk. 

After your teacher has checked your work, disassemble the models.
