The human factors audit was part of a hazard analysis which was used to recommend the degree of automation required in blowdown situations. The results of the human factors audit were mainly in terms of major errors which could affect blowdown success likelihood, and causal factors such as procedures, training, control room design, team communications, and aspects of hardware equipment. The major emphasis of the study was on improving the human interaction with the blowdown system, whether manual or automatic. Two specific platform scenarios were investigated. One was a significant gas release in the molecular sieve module (MSM) on a relatively new platform, and the other a release in the separator module (SM) on an older generation platform. 

Task Analysis and Error Analysis of the Blowdown Operation Task analysis was carried out in order to organize all the performance data about the way that workers process information, the nature of the emergency and the way that decisions are made. Figure 7.20 shows a tabular task analysis of the workers response to a significant unignited gas leak in MSM. The analysis was a combination of a tabular HTA and a CADET analysis (see Chapter 4). Human error analysis identified the major human failure modes which could affect time to blowdown (see Table 7.2). 

CR Yellow Alert Gas leak in MSM Audible alarm, yellow flashing light on fire gas panel Uncertain could be real 1. Accept alarm 2. Cz area technician 3. Make PA announcement 4. Determine which gas detector is in alarm (its location) Suspend current operation. Scan panels for flashing yellow or red light. Turn around to MSM Fire Gas panel. Press "accept" button CCR Layout MSM Fire Gas panel Visual and audible Whatever op is doing when alarm occurs Initially disorientating because MSM does not have its own sound source. Alarm could be missed if second simultaneous alarm occurs on main bank of Fire Gas panels... 

Go to radio. Radio Area Technician (AT) to go to MSM and verify gas leak. Radio channel availability Noise, Interference. AT may be busy. Channels may be unavailable... 

Make PA announcement for personnel to stop hotwork and stay away from MSM PA systems This message takes up time and distracts operator from watching Fire Gas panel. Consider taped messages.

The crystal structure of MsM OF compounds, where M = NH4, K, Rb, is made up of infinite chains of oxyfluoroniobate octahedrons that are similar to MNbOF4 chain-type compounds. Infinite chains are separated by isolated complexes NbFy2, whose structure is similar to that found in the island-type compound K2NbF7. The structure of the M5Nb30Fi8 compounds was described and discussed in Chapter 3.2. Due to the separation of the chains, the displacement of the niobium ion is in the same direction in all chains. The above displacement leads to a spontaneous polarization value that is as high as 4-5 pC/cm2. 

In a light-emitting MSM structure the two metal electrodes selected such that the work functions of the electrodes are near the edge of the valence band (VB) and the conducting band (CB) of the semiconductor, respectively, so that oppositely charge carriers are injected from the opposite electrodes. An ohmic and a rectifying contact is therefore formed in the MSM structure (see Fig. 9-22). 

A conjugated polymer of a high charge carrier concentration (n> 1017 cm-3) arranged between two mclal electrodes, can be understood as a MSM structure [40. ... 

The arrangement of the LECs offer some advantages compared to the PLEDs in an MSM or MIM arrangement [48] ...

Fluoroquinolones arenot recommended for treating infections in MSM or infections acquired in Hawaii, California, or other parts of the world where high-level resistance to fluoroquinolones is reported, or in heterosexuals with a history of recent foreign travel (including exposure froma partner with a history of recent foreign travel).
