Carbon Dioxide (CO2) Safety Program

Carbon dioxide (CO2) is a “sleeper hazard;” very little information outside scientific literature has been published to help facilities understand CO2 health effects and control CO2 exposures. This Carbon Dioxide Safety Program is designed to fill this gap. Breathing concentrations of 30% CO2, even with 70% oxygen, leads to unconsciousness in 30 seconds Your facility may have been doing ...

Seven Great Experiments Using the Wireless CO2 Sensor ...

2008-01-01· At least one classroom should have a CO 2 sensor for continuous monitoring and recording. There are several suitable units that could allow real-time monitoring or trend history with reporting. A visual, ‘traffic light’ type sensor could be used which would alert the teacher to provide more ventilation when 1500 ppm is exceeded.

"Ventilation Control Options" - Modular Building Institute

CO2 Sensors CO2 is a very stable trace gas. When exhaled by the occupants, CO2 can then be used to control ventilation systems. Many codes/standards require either a minimum ventilation rate of 15 cfm per person, intake and exhaust, continuous ventilation during occupied times, or a maximum CO2 of 1000 parts per million (ppm) (ASHRAE) as the set point. CO2 sensors can open the ventilation ...
