Abstract: A system and method for remotely managing gas concentrations in gas-sensitive facilities comprises a computer system communicatively connected to one or more atmospheric sensors and ventilation systems. When a sensor reports that a predetermined threshold for a measured atmospheric condition has been exceeded, such as for atmospheric concentrations of ammonia, the computer system generates an alert and forwards the alert across a wireless communications network to a user's mobile device. The user may select a user command to send to the computer system, whereupon the computer system may activate one or more ventilation systems in accordance with the response action or alternatively override the user command based upon one or more contextual determinations, the ventilation systems able to reduce the atmospheric condition to optimal, sub-threshold levels.
