11. A gas detector comprising:
a user interface configured to communicate information to a user, and to receive information from the user;
an alarm;
a sensor configured to detect oxygen content in the ambient air around the gas detector; and
a processor configured to:
receive sensed data indicative of oxygen content in the ambient air, the gas detector having a first alarm setting comprising a first predefined threshold;
when the sensed data is above the first predefined threshold, activate the alarm;
generating an acknowledgement request for the user asking if the gas detector has entered a normal operation zone;
determine when the gas detector enters the normal operation zone based on an acknowledgement response from the user; and
when the gas detector has entered the normal operation zone, deactivate the alarm and altering one or more settings of the gas detector,
wherein altering the one or more settings of the gas detector comprises changing the first predefined threshold to a second predefined threshold higher than the first predefined threshold, and
wherein the gas detector is configured to activate the alarm when the sensed data is below the second predefined threshold.
