E Houses which will contain all of the electrical controls, instrumentations, and other electrical equipment must meet some very strict standards in order to ensure that they are safe and functional. One of the ways these rooms are controlled is by having pressurized systems installed.
Pressurized systems are part of the National Fire Protection Act, these are recognized fire safety equipment that a lot of E Houses use in order to reduce or even eliminate the number of hazards by providing it with the correct amount of positive-pressure ventilation from a clean air source. Pairing this ventilation system with safeguards and fire suppression systems will help protect your equipment and control centers efficiently and effectively.
Positive Pressure In Control Rooms
Your control room must have a positive pressure that sits at 25 Pa (or one-tenth an inch of water). This level must be able to be maintained with all of the room’s openings closed up. There is room within the code for the pressure to lower when doors and other openings are open. However, in order for the pressure drop to be safe, there must be a minimum air velocity of 60 ft. per minute traveling through the openings.
Pressure E houses
Positive pressure E houses are specialized systems designed to maintain a safe and healthy work environment in locations where explosive gases or vapors may be present. By continuously supplying a steady inflow of breathable air, these enclosures facilitate the removal of gases, preventing their ingress and reducing the risk of potential hazards. In addition to their safety benefits, positive pressure enclosures contribute to improved indoor air quality within the workspace
Maintaining Safety and Air Purity
The primary function of positive pressure E houses is to ensure a constant outflow of gases from the chamber. By expelling gases, the section prevents the accumulation of explosive substances, safeguarding workers and equipment. Moreover, this continuous outflow process aids in purifying the air within the enclosure, effectively removing unwanted gaseous by-products generated during welding processes.
Commercially available positive pressure E houses are commonly referred to as habitats by manufacturers, highlighting their ability to create a controlled and secure working environment.
Achieving Optimal Indoor Air Quality
Indoor air quality (IAQ) is crucial to a safe and productive working environment. It encompasses temperature, humidity, ventilation, and pollutant control. While no specific IAQ standards are established by O.S.H.A. (Occupational Safety and Health Administration), the organization provides guidelines to address typical workplace IAQ concerns.
To ensure the well-being of workers, habitat technicians must implement practical solutions daily. These solutions encompass maintaining comfortable temperature and humidity levels, ensuring an adequate supply of fresh outdoor air, and effectively controlling pollutants from internal and external sources. By addressing these aspects, habitat technicians play a vital role in creating a safe and healthy workspace for the individuals working inside E houses.

E-House Locations
The decision of where to place your E-houses or control rooms is not one that can be taken lightly. There must be close attention paid to the placement of your control room and its relation to all of the sources of gases and vapors - including the evaluation of the different directions of the prevailing winds in the area of your build. An example of what this means is having one side of your control room facing a location that is declared to be free of even trace amounts of the flammable vapors and gases that are present on job sites, or that there is enough of a fan intake in order to provide a source of clean air for the control room or E-House.
Ducting may be used in order to reach a source of uncontaminated air for your control room, however, the ducts must be built out of non-combustible material, tested to be sure there are no leaks whatsoever, and must be maintained in order to ensure it is protected from damage and corrosion. There must also be pressure-sensitive switches as well as other safeguarding devices and systems installed in order to make sure that the low level of pressure is met.
