CO₂ Monitors and Alarms:

CO₂ monitors are devices that measure carbon dioxide levels in the air. They’re commonly used in indoor spaces like offices, classrooms, and industrial settings to ensure air quality and safety. Elevated CO₂ levels can indicate poor ventilation, which may lead to health risks, such as fatigue, headaches, and reduced concentration. Many CO₂ monitors come with alarms that trigger when CO₂ reaches a specific threshold, alerting occupants to take corrective actions like increasing ventilation. Advanced models may also integrate temperature and humidity sensors for a more comprehensive air quality assessment.

When using a hydrogen inhalation device indoors, CO₂ monitors or alarms may get triggered due to a phenomenon known as “cross-sensitivity.” Many CO₂ sensors, especially non-dispersive infrared (NDIR) types, can sometimes detect hydrogen gas as if it were CO₂, causing false alarms. This occurs because hydrogen can absorb infrared light in a way that interferes with the sensor’s readings.

To avoid this, it’s recommended to:

• Use the hydrogen inhalation device in a well-ventilated area.
• Consider upgrading to CO₂ monitors with sensors that are less prone to hydrogen cross-sensitivity, such as certain types of electrochemical sensors.
• Alternatively, temporarily disabling the CO₂ alarm during hydrogen inhalation sessions (if safe to do so) may be an option if ventilation is ensured.

To ensure safe use of hydrogen inhalation devices with the CO₂ sensor off, it’s important to maintain proper ventilation and follow safety guidelines. These devices are designed to keep hydrogen concentration well below the 4% Lower Explosive Limit (LEL).

Regular maintenance and adherence to these guidelines help keep hydrogen levels safe in indoor spaces.
