Location of Gas Detectors Each installation needs to be considered in its own right with reference to safety authorities and in compliance with mandatory local safety regulations The sensor must be operated in accordance with the User Manual to maintain safety reliability and to preserve safety integrity where applicable It is important that sensors are located in positions determined in consultation with those who have specialised knowledge of the plant or installation and of the principles of gas dispersion Reference should also be made to those responsible for the engineering layout and topology of the plant as they will be most familiar with the nature of the potential dangers and the most likely sources of gas release It is also important to recognise that the characteristics of the gas source can be influenced by many factors including the relative density or buoyancy of the gas the pressure at the point of release the ambient temperature and the ventilation of the site Sensor coverage cannot be simply expressed in terms of number per unit area sensors need to be sited where they are capable of monitoring those parts of a plant where gas may accumulate or where a source of gas release is expected to occur This way the earliest possible warning of a gas release can be given to initiate functions alarm functions or safe evacuation of the premises Sensor Management A very important part of an efficient gas monitoring sys
