Taking Remedial Action

Endurance Burn Under certain cou(itious, a successfully arrested flame may stabilize on the unprotected side of an arrester element. Should this condition not be corrected, the flame will eventually penetrate the arrester as the channels become hot. An endurance burn time can be determined by testing, which specifies that the arrester has withstood a stabilized flame without penetration for a given period. The test should address either the actual or worst-case geometry, since heat transfer to the element will depend on whether the flame stabilizes on the top, bottom, or horizontal face. In general, the endurance burn time identified by test should not be regarded as an accurate measure of the time available to take remedial action, since test conditions will not necessarily approximate the worst possible practical case. Temperature sensors may be incorporated at the arrester to indicate a stabilized flame condition and either alarm or initiate appropriate action, such as valve closure. 

Preliminary All <0.1 X OEL 0.1-1.5 xOEL Some >1.5 xOEL None if exposures are as low as reasonably practical. Investigate and carry out a more detailed survey. Investigate, take remedial action and repeat survey. 

Customer complaints are addressed under the heading of corrective action however, you should not limit your action to eliminating the cause and preventing recurrence. You also need to take remedial action to deal with the particular complaint - hence the requirements of element 4.13 also apply to the handling of customer complaints. 

Take remedial action to correct the particular nonconformity. 

Some >1.5 xOEL Investigate, take remedial action and repeat survey. 

Chelators bind metals so that they are more readily excreted in the urine. In the past, chelators were routinely prescribed to people with elevated blood lead levels in an effort to accelerate the excretion of lead in the urine. Unless the blood levels are excessively elevated the current treatment is to determine the source of the lead exposure and take remedial action. The problem with chelators is that they are non-specific and bind useful agents such as calcium. 

The methods for estimation of FED and FEC allow materials developers to assess their products, and if the fire toxicity is likely to be high, to see which species are to blame and take remedial action. Since incapacitation in a fire will result in a fire death in the same way as lethality (unless the incapacitated victim is fortunate enough to be rescued) it is more appropriate to use the incapacitation methodology of ISO 13571 than the rat lethality methodology of ISO 13344. 

To feel unwell is common, though the frequency varies with social and cultural circumstances. People commonly experience symptoms or complaints and commonly want to take remedial action. In one study of adults randomly selected from a large population, 9 out of 10 had one or more complaints in the 2 weeks before interview in another of premenopausal women a symptom occurred as often as 1 day in 3 in both studies a medicine was taken for more than half these occurrences. 

EPA generally takes remedial actions only at sites listed on the NPL (which currently lists 1300 sites). 

Many recent communication efforts about public health risks reflect the latter view. For instance, the success of risk communication programs about radon have been judged by the number of people who test for radon or take remedial action to reduce radon levels. Similarly, campaigns on smoking are assessed by the number of individuals who stop smoking. When behavior change is the criterion of success, the accuracy of the risk communication is not as important as its impact. 

Continue testing—do the charts indicate an in control situation, i.e., all points within the control limits If not, search for the cause and take remedial action. 

One might argue that once a safety-related issue has been identified it is too late to consider potential controls but this is far from the case. Just because a hazardous scenario may result from the fault it is by no means a foregone conclusion that actual harm will occur. There will usually be a human operator between the system and the patient who can work around the issue or take remedial action. In some cases, the provision of practical advice to users from a system expert may alleviate much of the real world risk until the issue is hxed. Important mitigations of this nature should be documented in the issue assessment and provide one means by which the advice may be propagated.

There is strong pressure to take remedial action. Its importance and urgency was expressed as early as 1972, when The Club of Rome published "The Limits to Growth" [2]. It is now widely recognised that continued economic development should be accompanied by more appropriate use of natural resources. Just how the economy should be organised to achieve such balanced growth is at present open to a great deal of debate [3].

Deviations from, or violations of, requirements [of the authorization], or unsatisfactory situations which have minor safety significance, may be identified at facilities or in the conduct of activities. In such circumstances, the regulatory body shall issue a written warning or directive to the operator which shall identify the nature and regulatory basis of each violation and the period of time permitted for taking remedial action (Ret [1], para. 5.19). This is the most common form of enforcement action and will, in most cases, suffice to remedy the safety issue. 

When a guideline value is exceeded this should be a signal (i) to investigate the cause, with a view to taking remedial action (ii) to consult with authorities responsible for public health for advice. 

The use of QC control charts and subsidiary aids like the Cusum plot is an example of facing the fact that Murphy s Law predicts that something wiU surely go wrong if we wait long enough. These tools help in catching such problems early so as to take remedial action. 

This discussion emphasizes that non-zero values for A" usually indicate potential uncertainties which are best avoided, if possible, by diagnosing the cause and taking remedial action, e.g., if A" > 0 a more selective analytical method such as different cleanup and chromatography and/or increased mass spectrometer resolution or, if A" < 0, changing columns and/or silylation to deactivate appropriate portions of the chromatographic train etc. However, if none of these remedies improve the situation, assumption of the appUcabdity of the calibration parameters B" and A" to analysis of sample extracts gives the working relation Equation [8.67].
