Work control

A comprehensive work planning and control system applying the defence in depth principle should be implemented so that work activities can be properly authorized, scheduled and carried out by either plant personnel or contractors, in accordance with appropriate procedures, and can be completed in a timely manner. The work planning system should maintain high availability and reliability of important plant SSCs. 

The comprehensive work contfol system should include any authorizations, permits and certificates necessary to help ensure safety in the work area and to prevent maintenance activities from affecting other safety relevant areas. The following specific matters should be considered in the work control system  

The authorizations, permits and certificates referred to in para. 5.15 should  

The work control system should be used to ensure that plant equipment is released from service for maintenance, testing, surveillance and in-service inspection only upon authorization of designated operating personnel and in compliance with the operational limits and conditions. It should also ensure that, following maintenance, testing, surveillance and in-service inspection, the plant is returned to service only upon completion of a documented check of its configuration and, where appropriate, of a functional test. 

The effectiveness of the work control process should be monitored by appropriate indicators (such as repeated work orders, individual and collective radiation

Health and safety planning and implementation emphasize jobs and tasks. Many DOE or Army Corps of Engineers sites have an established work control system (WCS) that is focused at the job and task level. Workers are familiar with the WCS and understand its content because each work-task package includes checklists and permits. This is a normal part of daily work. The WCS is a practical vehicle for managing and conducting these activities and supports the HASP by providing a mechanism to accomplish the following ... 

Key documents that are developed during the planning stages can be used to focus and direct the compliance strategy, to outline the health and safety program/plan requirements, and to establish work controls. These documents are usually developed after contract award and before mobilization. 

Not all required tasks and hazards can be predicted during the development of a HASP. The plan describes the ongoing hazard analysis and work control process, defines the means of identifying job- or task-based requirements and controls, and discusses ways to inform workers about requirements derived from ongoing job or task hazard analyses.

The overall conclusion that can be drawn from a survey of CPI data collection systems is that the better systems do attempt to address the causes of human error. However, because of the lack of knowledge about the factors which influence errors, the causal information that is collected may not be very useful in developing remedial strategies. General information in areas such as severity, work control aspects and the technical details of the incident will be required in all data collection systems. However, in almost all cases a structured process for causal analysis is lacking. Some of the requirements for causal analysis are set out in the following sections. 

The use of block copolymers to form a variety of different nanosized periodic patterns continues to be an active area of research. Whether in bulk, thin film, or solution micelle states, block copolymers present seemingly unlimited opportunities for fabricating and patterning nanostructures. The wealth of microstructures and the tunability of structural dimensions make them a favorable choice for scientists in a variety of research fields. As reviewed here, they can function as nano devices themselves, or act as templates or scaffolds for the fabrication of functional nanopatterns composed of almost all types of materials. However, there are still two obvious areas which require more work control of the long-range 3D nanostructure via more user-friendly processes and the identification of new materials with different functional properties. 

Toensure that necessary hot work for maintenance, construction, or modifications is done safely to prevent ignition of fires and protect life and property, the hot work control procedure should include the following as a minimum ... 

Membranes were pre-compacted at 800 psig for approximately one hour, the pressure then being reduced to 600 psig for collection of performance data. At the beginning of this work, control samples were soaked in buffer solutions for times corresponding to membrane exposure. It was subsequently found that control samples were unaffected by buffer solution alone and this procedure was discontinued. 

Controls work control/permit system to control activities that might disturb ACM. This system requires the person requesting work to submit a job request form to the Asbestos Program Manager before any work is begun. 

Automatically working control systems are able to eject those tablets separately which fail the requirements (rejection mechanism), and they adjust the machine for die filling or compression force and collect only those tablets which meet the requirements. Two alternative principles for automatic tablet weight control and adjustment are possible, depending on the application and selected machine type. The principle of control of compression force is based on measurement of the final compression force under constant tablet height. This principle is used for all applications where tablet weight accuracy and constant tablet density are less critical.

The method described above is usually sufficiently accurate for routine works control, but chlorates, which are always present, will also liberate iodine from potassium iodide. A more accurate method is based on titration with a standard solution of arsenious oxide which is oxidized by the available chlorine into arsenic oxide according to the following equation ... 

OSHA regulates the benzene soluble fraction of coal tar pitch volatiles and mineral oil mist, which contain several ofthe PAH compounds. Employers of workers who are occupationally exposed must institute engineering controls and work practices to reduce and maintain employee exposure at or below permissible exposure limits (PEL). The employer must use engineering and work controls, if feasible, to reduce exposure to or below an 8-hour time-weighted average (TWA) of 0.2 mg/m for coal tar pitch volatiles and 5 mg/m for mineral oil mist. 

The enzymatic reaction ran without complications. In spite of the automated control of the pH, the reaction was supervised full time in shift-work. Control of pH and temperature worked smoothly and after 48 hours the three batches showed degrees of conversion as observed in Process Development (Tab. 3). 

Many epidemiologists believe it is only a matter of time until the next influenza pandemic occurs. The severity of the next pandemic cannot be predicted, but studies suggest that its effect in the United States could be very bad. In the absence of any working control measures (vaccination or drugs), it was predicted that in the United States a quite medium pandemic could cause 89,000 to 207,000 deaths, between 314,000 and 734,000 hospitalizations, 18 to 42 million outpatient visits, and another 20 to 47 million people being sick. Between 15% and 35% of the US population could be affected by an influenza pandemic, and the economic impact could range between 71.3 billion and 166.5 billion. 

At the end of a 30-min reaction period, the plasma was switched off and the feed of anhydrous ammonia gas was stopped. The propylene beads were evacuated for am additional 30 min to remove the unreacted species. The beads exposed to ammonia gaseous plasma are referred to as PPB-NH2. To characterize the surfaces of the control and the modified membranes, the FT-IR spectrometry ( Nicolet 7000 Series) with an ATR attachment was used. KRS-5 reflection plate at an incident angle of 45° was employed for FT-IR-ATR work. Control or modified membrane samples were applied on both sides of the reflection plate. Thi allowed spectra of only few micron thick layer of the surfaces contacting the KRS-5 reflection plate to be obtained. Immobilization of albumin onto membrane having surface amino groups has been described (2,3).
