Summary
This hazard alert explains multi-gas monitor selection and use in oil and gas operations. It highlights hydrogen sulphide monitor limitations, unreliable flammable-gas detection under some atmospheric conditions, and misleading alarm cessation. Guidance covers sensor selection, calibration, bump testing, breathing-zone positioning and immediate evacuation following any alarm.
