A system to regulate breathing air of a plurality of sealing and locking helmets and a plurality of supplied air respirators producing a plurality of lower pressure air supply of a plurality of people simultaneously using air regulators, valves, pressure sensors and a temperature sensor that measures temperature in the air module. The system includes a plurality of temperature sensors of measuring temperature of environment around each person of one of the sealing and locking helmets or supplied air respirators, a gas analyzer, an air module processor to control the valves, receiving data from the pressure sensors, controlling lower pressure air supply and presenting data on a display with real time updates that are presented in less than a few milliseconds providing a continuously imported status that achieves safe entry in a hazardous area with fewer accidents by operators, cleaning crew, inspectors, welders, installers, and loaders.
