Fixed safe normal operation

When Windows won t start properly, it is probably due to a driver or some piece of software that s not loading correctly. To fix problems of this nature, you should boot Windows in Safe Mode. In Safe Mode, Windows loads a minimal set of drivers (including a VGA-only video driver) so that you can disable an offending driver. To start Windows in Safe Mode, press the F8 key when you see the Starting Windows display during Windows bootup. This will bring up a menu that wiU allow you to choose to start Windows in Safe Mode. Once booted in Safe Mode, you can uninstall any driver you suspect is causing a Windows boot problem. Upon reboot, the system should go back to normal operation (non-Safe Mode). 

Normally a guard is installed on a moving part of the machine, which acts as a barrier to prevent the entry of any part of the human body in the hazardous area. It is also possible that a safety device is installed that prevents or interrupts the operation if part of the operator s body is in a hazardous area or requires its withdrawal prior to machine operation. The guard or safety device itself must not constitute a hazard, must be safe, low maintenance, easy-to-use, automatically controlled, or fixed on the machines. There are different types of guards and safety devices available according to the design and demands of machines. 

In the subsequent steps the procedures to answer the two questions differ. In the first case, the assessment of a newly designed plant, usually the desired conversion, the optimal process temperature and the required production rate are fixed. Also the mode of operation, such as continuous or discontinuous, is predetermined by demands on selectivity and 3deld. The safety evaluation now has to assess, whether or not the parameter combination selected fi om the multi-dimensional space defined by reactor size, initial concentrations, characteristic reaction time as well as coolant and feed temperature can ensure safe operation under normal conditions.
