| The normal level of oxygen in breathing air is 20.9%. This level sustains life comfortably with an adequate safety margin either side of the atmospheric value. However in conditions of oxygen deficiency, which can occur due to the displacement of oxygen by the release of other gases, impairment of mental functions often confuses the victims, so that they fail to recognise the danger they are in. AS OXYGEN DROPS, UNCONSCIOUSNESS AND DEATH CAN RESULT If the level of oxygen drops below 17%, due to displacement by nitrogen, carbon dioxide or other gases, an individual will suffer impairment. At 15% they will quickly lose consciousness, possibly causing injury, brain damage or death. Conversely, oxygen enrichment is also known to be hazardous. With an oxygen concentration only 2% above ambient levels, a significant increase in the flammability of common materials is observed. The Model EC96 enables continuous monitoring of the oxygen level within confined rooms and work areas. Adjustable alarm contacts give early warning of changes in oxygen levels, allowing action to be taken. An analogue output signal is available for connection to recorders or remote data-logging devices. The instrument is supplied with 25 meters of cable as standard, allowing the cell to be mounted remotely, if required.
