Monitor zone

It is performed in the open air, where it is not easy to define protected zones and have them complied with (monitored zone, controlled zone). 

HCF operators use the instrumentation described above to monitor Zone 2A confinement boundary integrity. The functional performance of this equipment is assured by means of administratively controlled TSR surveillance activities. Zone 2A-to-Zone 2 differential pressure instrumentation is subject to periodic channel functional testing and calibration, and the ventilation system fan sequencing interlock is periodically tested by HCF operations personnel in accordance with operating procedures. 

Finally, no therapy may be programmed in a VT zone. Why would one do this The idea here is to allow the ICD to record a previously occult arrhythmia, particularly in the slowest zone of detection. This type of VT zone is commonly referred to as a "monitor zone."... 

At a depth h in the suspension at time tj in a sedimenting suspension all fineparticles with velocities v, = hj/t will have cleared the monitoring zone. The number of fineparticles of settling velocities smaller than leaving the zone and being replaced by an equal number of fineparticles per unit volume in the monitoring zone is given by the relationship... 

Before the performance of the loading we have to apply 5 up to 12 sensors, according their size, on the cylindrical part of the drums and after a short check of the required sensitivity and the wave propagation the pneumatic pressure test monitored by AE can be performed. The selection of the sensors and their positions was performed earlier in pre-tests under the postulate, that the complete cylinder can be tested with the same sensitivity, reliability and that furthermore the localisation accuracy of defects in the on-line- and the post analysis is sufficient for the required purpose. For the flat eovers, which will be tested by specific sensors, the geometrical shape is so complicated, that we perform in this case only a defect determination with a kind of zone-location. 

If the primary ion beam is used to continuously remove material from the surface of a specimen in a given area, the analytical zone is advanced into the sample as a function of the sputtering time. By monitoring the secondary ion count rates of selected... 

Work zones are often temporary. Many times, onee the work has been eondueted, the zone boundaries ehange and sometimes beeome support zones. Temporary work zones ean be used to eflfeetively manage regulatory seope. Area and personnel exposure monitoring is erueial in order to verify that zoning, eontainments, work praetiees, and proeedures have been designed appropriately and maintain worker health and safety. 

Worker eomfort areas ean be loeated in site work zones. These eomfort zones allow workers to take breaks and rest without being eontaminated. These areas are designed to maintain the safety of workers and generally require speeial proeedures for ingress and egress, personnel and air monitoring, potable water eonsumption, and restroom use [1],... 

Site H was the only site at which the contractor had implemented comprehensive and effective site control elements. The Site H contractor had established site work zones, a buddy system, and site communication procedures consistent with 1910.120(d). This contractor had also established exclusion zones and contamination reduction zones to control migration of site contaminants to clean areas of the site when work within these areas introduced the potential for exposure to hazardous contaminants. The audit team supported this contractor s use of flexible and temporary work zone boundaries based on monitoring results and hazard determinations. 

The bench where decontamination took place was only a few feet from the thermal unit and was not isolated from exclusion zone activities employees moved freely between their work stations in the exclusion zone and the decontamination bench. In addition, the subcontractor did not conduct monitoring activities to support work zone designations. Neither Site K contractor used warning signs to delineate exclusion zones, as required by their respective health and safety plans. 

At Site I, personnel and equipment decontamination procedures were not monitored for their effectiveness in accordance with HAZ-WOPER requirements. The Site I subcontractor did not have provisions for particulate sampling, evaluating exposure to pesticides and herbicides, or evaluating the effectiveness of site zone boundaries and personnel decontamination procedures. Additionally, monitoring had not been conducted to verify that decontamination was not necessary for employees who leave the exclusion zone and enter a clean zone without undergoing decontamination. 

Contraetors at Sites B, D, E, and F had not evaluated the effeetive-ness of their PPE programs and did not monitor deeontamination proeedures through the use of surfaee sampling or other quantitative means. At Site E, improper use of PPE was observed several times in the exehi-sion zone, and monitoring data was not kept eurrent in the eomputer when the SSO was off site for an extended period of time. 

The success of separation of colored compounds is usually monitored visually. Such compounds absorb a particular portion of the polychromatic (white) light in the visible wavelength range. The remaining radiation (complementary radiation) is reflected and detected by the eye it determines the color of the substance zone. Table 1 correlates the wavelengths, colors and complementary colors. 

Allow the plant to run automatically for a period of some days either with no artificial load or with a small one of fixed value. If no means of recording are built into the plant then recorders should be introduced and placed in representative positions in the various zones for the duration of the tests. Periodically examine the traces or monitor printouts. These will give an indication as to whether the plant is controlling correctly on light load. 

Confirmation analysis In most cases, the occurrence of dynamic resonance can be quickly confirmed. When monitoring phase and amplitude, resonance is indicated by a 180° phase shift as the rotor passes through the resonant zone. Figure 44.44 illustrates a dynamic resonance at 500 rpm, which shows a dramatic amplitude increase in the frequency-domain display. This is confirmed by the 180° phase shift in the time-domain plot. Note that the peak at 1200 rpm is not resonance. The absence of a phase shift, coupled with the apparent modulations in the FFT, discount the possibility that this peak is resonance-related.
