Development of principles of ensuring safety in pneumatic control systems

The main aim of the task was to develop suitable tools, including guidelines, check lists and a draft of a validation procedure for pneumatic control systems in machinery, which would support the operation of notified bodies in the scope of assessment of machinery and state bodies authorized to carry out surveillance of the market and the activity of manufacturers and users of machinery regarding proper designing, constructing and maintenance of those systems. The task involved: - a review of literature, regulations and standards on the subject of this task - identification of dangerous zones and hazards posed by pneumatic systems in stationary industrial machinery - defining safety requirements regarding the construction of those systems with consideration for resistance to defect - defining the principles of conducting and documenting validation of pneumatic control systems for the purposes of assessing compliance Moreover, the following were developed: - recommendations for constructing and maintaining pneumatic control systems with safety functions - check lists for checking compliance of pneumatic industrial machinery with safety requirements - a draft procedure for checking validation of pneumatic control systems The final results of the task were as follows: guidelines for using and maintaining pneumatic systems with checklists and a draft procedure for checking validation of pneumatic control systems for assessing compliance.
