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 what it has been …

Easy solutions for indoor air problems at schools - Vallox

Carbon dioxide -based control is an excellent means to control ventilation automatically based on the need in premises where the number of occupants varies. The carbon dioxide -based control identifies when people enter the premises and enhances the efficiency of ventilation almost steplessly. This way, ventilation is not too efficient when there are only a few people present in the classroom but the …

A Revised Control Strategy to Reduce CO2 in an Under-Ventilated Classroom

The addition of outside air to cool the classroom did help reduce the classroom CO 2 levels, but the outside air dampers were not directly controlling to the CO 2 setpoint. A revised BAS control strategy was implemented to allow the outside air dampers to meet the requirements of both (1) CO 2 setpoints and (2) economizer mode setpoints.. Even if your outside air dampers don’t have feedback sensors to …

Demand Controlled Ventilation and Classroom Ventilation …

01/05/2012· Carbon dioxide (CO{sub 2}) sensors are often deployed in commercial buildings to obtain CO{sub 2} data that are used, in a process called demand-controlled ventilation, to automatically modulate rates of outdoor air ventilation. The objective is to keep ventilation rates at or above design specifications and code requirements and also to save energy by avoiding excessive ventilation rates. …

Sick Classrooms Caused by Rising CO2 Levels

13/01/2014· Carbon dioxide levels in the classroom have been shown to be directly related to a students alertness and ability to concentrate. High levels of carbon dioxide indicate a lack of fresh air intake and that negatively affects the health, attendance rate and learning ability of students. “Increases in indoor CO 2 concentrations… were associated with statistically significant and meaningful …

Why Measure Carbon Dioxide Inside Buildings?

2 measurement taken in a school classroom during first period. It is unlikely that the CO 2 concentration will have accumulated to the point where equilibrium has been reached. Therefore, assumptions of outside air ventilation rates based on this CO 2 measurement will lead to an overestimation of the ventilation rate. Thus low CO 2 readings don’t necessarily mean adequate ventilation. On the other …

Indoor Air Quality in Classrooms and COVID19 |

Since outdoor air is approximately 400ppm, indoor CO2 levels should be no more than 1,100 ppm. Note that this guideline is not designed to limit the amount of CO2, but rather to indicate that a proper level of clean air (15-20 CFM/person) is being distributed in a classroom. And OSHA and the US Green Building Council have even tighter indoor ...
