Who can change the settings of a gas alarm level?

The ability to change the settings of a gas alarm level is typically reserved for individuals who have the appropriate authority and understanding of the implications such adjustments may have on safety. A person with the responsible officer's authorization signifies that they have been granted specific powers to make such changes, likely due to their understanding of the operational protocols and safety standards that must be upheld. This ensures that any modifications to alarm settings are made in accordance with safety procedures and regulations, minimizing the risk of hazardous situations that could arise if alarm settings are improperly adjusted.

The mine supervisor and qualified technicians may have roles that involve ensuring safety but may not have the authority to independently change alarm settings without explicit authorization. Similarly, while mining staff members trained in gas safety may have familiarity with alarm systems, they typically do not possess the formal authority to make changes unless explicitly authorized to do so by the responsible officer.
