White Paper Bump testing saves lives Paper describes the correlation between bump test intervals and detection failures Bump test prior to each days use: Veri es functionality of alarms with known concentration of gas Simulates alarm conditions by testing above alarm levels Only way to know sensor is working Created to reduce owners cost of calibration Bump test failures: 3 in 1,000 or 0.3% (trivial) Bump tests done every 20 days doubles failure rates 1 out of every hundred will fail every 25 days if not bump tested 1 in 2,500 fail in hazardous atmospheres if not bump tested Sensor Failures Occur: Due to shocks from falls, humidity and dust from the environments they are used in fi
