Situational violations

Situational violations occur when particular job pressures at particular times make rule compliance difficult. They may happen when the correct equipment is not available or weather conditions are adverse. A common example is the use of a ladder rather than a scaffold for working at height to replace window frames in a building. Situational violations may be reduced by improving job design, the working environment and supervision. 

Situational violations, or straying from accepted practices by bending a rule or procedme, can normally result from one or more of the following ... 

Exceptional - exceptional violations rarely occur in part because they are only made when a new or unusual task is required to be undertaken or an emergency is required to be responded to. This type of violation is more likely to occur in organisations that have a high tolerance of routine and situational violations in the place. Typically with exceptional violations, only achieving the desired outcome of the task is considered and any other issues are excluded, such as cost or safety. 

Situational violations happen when the demands of the particular circumstances are seen as more important than compliance with the rule pressure of work, not enough time or equipment to do the job. Better planning and supervision can assist. 

Though the case of constant matrix elements and the example investigated by Hite are the only situations for which Che stoichiometric relations have been fully established in pellets of arbitrary shape, it is worth mentioning situations in which these relations are known not to hold. When the composition and pressure at the surface of the pellet may vary in an arbitrary way from point to point it seems unlikely on intuitive grounds that equations (11.3) will be satisfied, and Hite and Jackson [77] confirmed by direct computation that there are, indeed, simple situations in which they are violated. Less obviously, direct computation [75] has also shown them to be violated even when the pressure and composition of the environment are the same everywhere, in the case where finite resistances to mass transfer exist at the surface of Che pellet. 

General Situation. Both unidirectional diffusion through stagnant media and equimolar diffusion are idealizations that ate usually violated in real processes. In gas absorption, slight solvent evaporation may provide some counterdiffusion, and in distillation counterdiffusion may not be equimolar for a number of reasons. This is especially tme for multicomponent operation. 

In attainment areas, new large faciUties must be designed to incorporate the best available control technology (BACT). Generally, BACT is more stringent than RACT and equal to or less stringent than LAER. In addition, there are also rules that specify how much deterioration in baseline air quaUty a new facihty can cause. In no situation can the faciUty cause a new violation in the NAAQS. 

The situation is more subtle for the antisymmetrically coupled mode. As shown in fig. 17, this vibration, in contrast to the symmetric mode, asymmetrizes the potential and violates the resonance. This should lead to a decrease in the splitting. Consider this problem perturbatively. If the vibration and the potential V Q) were uncoupled, each tunneling doublet Eq, Ei (we consider only the lowest one) of the uncoupled potential V Q) would give rise to a progression of vibrational levels with energies... 

This section is concerned with errors that are often classified as "violations," that is, situations where established operating procedures appear to have been deliberately disregarded. Such violations sometimes arise because the prescribed way of performing the task is extremely difficult or is incompatible with the demands of production. Another cause is lack of knowledge of the... 

It is common practice that procedures and job-aids are often developed either by plant manufacturing companies or process designers with minimal participation by the end-users, usually plant workers. This has led to situations where the indicated sequence of actions was incompatible with the way the job is done in practice. This presents great problems for the workers who will have to reconcile a potential violation of procedures with a well established method of operation. 

There are very few exceptions to this rule, and only a trained organic chemist can be expected to know when it is permissible to violate this rule. Some instructors might violate this rule one or two times (about half-way through the course). If this happens, you should recognize that you are seeing a very rare exception. In virtually every situation that you will encounter, you cannot violate this rule. Therefore, you must get into the habit of never breaking a single bond. 

The detection of potential mixing constraints violations at an intermediate operating state is based on a worst-case scenario with the maximum potential for the species to coexist, and which corresponds to the following situation ... 

Theorem 5 (Modal Truth Criterion for Quantitative Constraints). A constraint x.. k is necessarily satisfied in a situation s iff there is a situation t equal to or necessarily previous to s in which x.. k is satisfied and for every step C possibly before s that possibly violates x.. k, there is a step W necessarily before C that ensures x.. k in s. 

Class II recalls are those in which the use of or exposure to a product found in violation of the law may cause a temporary health problem that is reversible, or in which the situation would not cause serious adverse health consequences. Examples of this type of recall would include uncertainty of the sterility of an injectable product, Salmonella contamination of various types of oral dosage forms, inadequate directions for use, and improper buffering of solution for injection [20]. 

The situations which violate the definition of "tree-like"- involve a "diamond" as in (4) or a triangle as in (5) ... 

Sometimes when a mineral becomes supersaturated, there is no logical aqueous species in the basis with which to swap the mineral. Such a situation occurs when no species appear in the reaction to form the mineral. Wolery (1979) and Reed (1982) refer to such a situation as an apparent violation of the phase rule, because adding the mineral to the basis would produce more phases in the system than there are components. 

Unfortunately, the continuous time representation of PP/DS can cause PP/DS campaigns not to satisfy the restrictions of the PLSP model that there is at most one setup operation per bucket. Another reason might be that due to manual modifications of the PP/DS plan the PLSP constraints are violated. Therefore, the PLSP model in the SNP optimizer has been extended in order to work with setup situations that are inconsistent with the PLSP. Given an initial setup state situation, the SNP optimizer tries to construct a model that keeps the cross bucket setup state conservation as good as possible. For example, in buckets in which there are already more than two different products no additional products may be planned. It is only allowed to extend the campaigns.
