Abstract

Methods and systems for maintaining an atmosphere inside a habitat enclosing a work station and shutting down one, more than one, or all operational equipment inside and/or outside the habitat upon the occurrence of an adverse event. Concentrations of explosive, flammable, and/or poisonous gases or vapors are sensed, transmitted to a logic device, as are temperature, pressure, and/or humidity. HVAC units and air extraction units controlled by the logic device maintain acceptable pressure, temperature, and/or humidity. Any grit and dust may be extracted. Any explosive, flammable, and/or poisonous gases or vapors are extracted employing an emergency gas extraction sub-system controlled by the logic device. The logic device shuts down one, more than one, or all operational equipment inside and/or outside the habitat (for example as dictated by the client, law, or regulation) upon receiving one or more adverse event signals.
