Checking actions

These activities will involve all relevant departments based on the concepts of the Plan, Do, Check, Action Cycle, Right First Time, and that each employee has a role to play in achieving product quality. 

Check all wiring and electrical controls, for correct circuitry, security of terminals, continuity, insulation, compliance with safety regulations such as lEE, marking of terminals and cables, etc. Check action of all controls as far as may be possible without running any item [63]. 

Review the assessment on future occasions to check action has been taken, if required... 

Insure written operating procedures include safety checks, actions, maintenance... 

The PDCA management model is applied to coal mine hazard information closed-loop management system. It will implement the closed-loop hazard information management according to the science program of plan-do—check-action, in the meanwhile, it increases the work of information audit and feedback about the hazard information input, the hazard rectification, assessment and other information. It makes various processes closely linked and hazard information timely and effective... 

Figure 19.1 Plan, Do, Check, Action (PDCA) Cycle (according to Deeming).

Check action of iiisirumenis, continuity of thermocouple connections and instrument circuits. Check control valves are correct for direction of flow and action on air failure H V H CHV... 

Checking action of instruments and contrd valves, testing electrical controls and alarms and so on. 

At the completion of the review of the report, an action plan is formulated and changes agreed upon by the committee are implemented. A final check must be made by management to ensure that these changes are actually completed. 

Trip Valves The trip valve is part of a system that is used where a specific valve action (i.e., fail up, Fail down, or lock in last position) is required when pneumatic supply pressure to the control valve falls befow a preset level. Trip systems are used primarily on springless piston ac tuators requiring fail-open or fail-closed acrion. An air storage or Volume tank and a check v ve are used with the trip valve to provide power to stroke the valve when supply pressure is lost. Trip valves are designed with hysteresis around the trip point to avoid instabihty when the trip pressure and the reset pressure settings are too close to the same value. 

A mathematical analysis of the action in Kady and other colloid mills checks well with experimental performance [Turner and McCarthy, Am. Inst. Chem. Eng. J., 12(4), 784 (1966)], Various models of the Kady mill have been described, and capacities and costs given by Zimmerman and Lavine [Co.st Eng., 12(1), 4-8 (1967)]. Energy requirements differ so much with the materials involved that other devices are often used to obtain the same end. These include high-speed stirrers, turbine mixers, bead mills, and vibratoiy mills. In some cases, sonic devices are effec tive. 

Various materials are used in dental prosthetic practice for the preparation of dental implants, crowns, and bridges. Some of these materials contain copper, which is added in order to improve mechanical or/and chemical properties, but some of them may contain the copper as an impurity. Considering the fact that dental implants remain in the oral cavity for a long time, and that they are exposed to the corrosive action of oral fluids and various kinds of food and beverages, it is necessary to check their possible harmful effects upon the human health. 

Check whether a documented system is in place, which covers the reporting, investigation, root cause analysis and corrective actions taken. 

Direct or rigid couplings Flexible couplings Delayed-action couplings Construction and principle of operation Belt drives Checking the suitability of bearings Suitability of rotors for pulley drives... 

With local cathodic protection, the off potential measurement cannot be used directly to check the protective action because, due to the mixed type of installation of the protected object and foreign cathodic structures in the soil, there is a considerable flow of cell currents and equalizing currents. The notes to Eq. (3-28) in Section 3.3 are relevant here, where the // -free potentials must be substantially more negative than the off potential of the protected object. If t/ ff is found to be more positive than U, this does not confirm or conclusively indicate insufficient... 

Corrective action Do multipoint calibration invalidate data collection since last zero/ span check within control limits... 

Routine All Differ significantly from previous survey Check values, mean, range, etc. Is there compliance with OEL and if so what is confidence Investigate, consider remedial action detailed survey or change protocols. 

Environmental management system documentation Document control Operational control Emergency preparedness and response Checking and corrective action... 

Corrective Action Use tracer dye to conflrm and identify exact nature of problem. Check clarifier internals such as mixing baffles and modify as needed. Cause Low density floe. 

Corrective Action Check pump and meter settings. Conflrm thast setting correspond with anticipated chemical feed rates. 

Corrective Action Check operation of feed pump. Check pump settings. 

Take the agreed action and check that the variance has been corrected.
