Abstract
A gas detection system and early warning method utilize normalized data to determine a sample coefficient used to estimate an actual concentration of a gas in the early stages of gas exposure.
Claims26
A method of determining a concentration of a gas comprising:
- detecting a presence of a detected gas with a gas detector;
- triggering a timer when a detected concentration of the gas reaches a predetermined level;
- measuring the concentration of the gas at a first time;
- measuring the concentration of the gas at a second time at an end of the timer;
- determine a rate of change of the concentration of the gas from the first time to the second time;
- comparing the rate of change to a known standard;
- and
- determining, from the comparison of the rate of change to the known standard, an estimated actual concentration of the detected gas.

A method of bump testing a gas detection system:
- exposing a sensor of the gas detection system to a calibration gas
- detecting a presence of the calibration gas with a sensor of the gas detection system;
- triggering a timer when a detected concentration of the calibration gas reaches a predetermined level;
- measuring the concentration of the calibration gas at a first time;
- measuring the concentration of the calibration gas at a second time at an end of the timer;
- determine a rate of change of the concentration of the calibration gas from the first time to the second time;
- comparing the rate of change to a known standard;
- determining, from the comparison of the rate of change to the known standard, an estimated actual concentration of the calibration gas;
- and
- triggering a response of the gas detection system when the estimated actual concentration of the calibration gas exceeds a predetermined setpoint.
