Donning procedure

All tight-fitting respirators, whether halfmask or full face piece, required for use must be fit-tested on an annual basis. The purpose is to ensure a specific make, model, style and size respirator properly fit a user. Annual fit testing also ensures all users are properly trained on donning procedures, at minimum once per year. Fit testing is accompanied by a medical evaluation to reinforce that the user is fit to wear the respirator.

Another characteristic similar to A/ 100 is the Distribution Octane Number (DON) proposed by Mobil Corporation and described in ASTM 2886. The idea is to measure the heaviest fractions of the fuel at the inlet manifold to the CFR engine. For this method the CFR has a cooled separation chamber placed between the carburetor and the inlet manifold. Some of the less volatile components are separated and collected in the chamber. This procedure is probably the most realistic but less discriminating than that of the AJ 100 likewise, it is now only of historical interest. 

If a tran sition state has notheen reach ed after a certain niiinherof steps, th e user may n eed to upgrade th e Hessian an d repeat th e calculation. It may be necessary if many calculation steps have been don e, and the curren t geo in etry differs con siderably from th e starting poin t. fh e Hessian calculated at th e starting poin t an d updated at each n e v poin t m ay n ot be appropriate at the geo in etry reach ed by th e search. fh is procedure can also h elp to get to a good startin g point where the Hessian has a correct structure with only one negative eigen value. 

The procedure we followed in the previous section was to take a pair of coupled equations, Eqs. (5-6) or (5-17) and express their solutions as a sum and difference, that is, as linear combinations. (Don t forget that the sum or difference of solutions of a linear homogeneous differential equation with constant coefficients is also a solution of the equation.) This recasts the original equations in the foiin of uncoupled equations. To show this, take the sum and difference of Eqs. (5-21),... 

This is a way to do this procedure without having to use one of those crazy tube furnaces stuffed with thorium oxide or manganous oxide catalyst [21]. The key here is to use an excess of acetic anhydride. Using even more than the amount specified will insure that the reaction proceeds in the right direction and the bad side reaction formation of dibenzylketone will be minimalized (don t ask). 18g piperonylic acid or 13.6g phenylacetic acid, 50mL acetic anhydride and 50mU pyridine are refluxed for 6 hours and the solvent removed by vacuum distillation. The remaining residue is taken up in benzene or ether, washed with 10% NaOH solution (discard the water layer), and vacuum distilled to get 8g P2P (56%). 

Effective and well planned maintenance can reduce the operating cost of your pumps and other ec]uipment as this example demonstrates. With differential pressure gauges on the pump, an amp meter and flow meter you can determine if strict tolerance parts arc worn. This indicates the need to take the pump into the shop for corrective procedures. If you don t do it, you are wasting your annual operating budget. As we mentioned in Chapter 6, the Wear Rings should be called Efficiency Rings. Now you know why. 

Shortcut Equipment Design Methods tend to become buried in design procedures, even computer-based ones. Therefore they often become part of the mix and don t stand free as separate entities. This is not bad. These methods need to be placed wherever they are useful. However, it is also good to draw them out since many everyday problems can be solved with undiluted shortcuts. 

Don t write procedures that violate published policies. 

Don t use customer procedures and forms within your processes. Translate customer requirements into your language and visa versa. 

Don t put people s names, titles, and locations in your procedures. 

Don t accept any application for a new procedure until you have determined where it fits in the system and how it will interface with other procedures. 

Don t ignore people s comments - you may need their support in implementing the procedure later. 

Don t produce project/product specific procedures that conflict with the established quality system. 

Don t state the issue status of reference documents in your procedures and specifications unless absolutely necessary. 

Any operation that relies on skills doesn t need a procedure. However, the operator will not be clairvoyant - you may need to provide procedures for straightforward tasks to convey special safety, handling, packaging, and recording requirements. You need to ensure that you don t make your processes so complex that bottlenecks arise when the slightest variation to plan occurs. The setting up of equipment, other than equipment typical of the industry, should be specified to ensure consistent results (see later in this chapter under Verification of job set-ups). In fact any operation that requires tasks to be... 

Don t work to instructions unless provided in the quality system procedures, product specification, production plan or in approved change notices or remedial action instructions or by the nonconformity review board. 

Don t change record blanks without authorized changes to the related procedure. Don t leave records lying around. 

Don t limit the scope of your audit program to the procedures. 

Where an effective informal system exists and is followed, the issue is one of style, not substance. A facility or unit may have a strong safety culture and sound safety practices, but its managers lack the habit of form documentation, or simply don t think it is important. Assuming that safety performance meets applicable standards, you will probably assign cases like these a relatively low priority, compared with other noncompliance situations. Cases like these are also often the easiest to fix since the fundamentals are already in place, what s required is simply to formalize the informal system by preparing and implementing documentation procedures. 

The amount of spacing between items is not significant in Gaussian input. In the route section, commas or slashes may be substituted for spaces if desired (except within parenthesized options, where slashes don t work). For example, the previous route section used a slash to separate the procedure and basis set, spaces to separate other keywords, and commas to separate the options to the Unite keyword. 

Subject a graph of some CjjH2jj,2 the two procedures described in Sec. 63(a) and (b) as often as possible. Since there are, in this case, no distinct endpoints the graph is eventually stripped of all its endpoints and we are left with one of the three in Fig. 5 represented forms. To fix ideas, consider, for example, the one in which each arc has two distinct endpoints. (This is, incidentally, the only one among the three forms which can be called a graph according to the definition of Sec. 29 don t forget requirement I )... 

Explain procedure and discuss pain during procedure and post-operative morbidity complications (Table 19.2). Don t minimize the severity of the post-peeling phase, which may preclude social activities for several days. 

This chapter ends with a tested procedure to represent the many photochemical rei dons on silica gel.
