As a medical gas installer, your job is to install and assemble gas pipes in medical facilities. Unlike regular pipe installations, you work with medical gas and vacuum systems. Your responsibilities are to follow all laws, codes, rulings, and regulations to ensure the facility follows federal standards. You also test existing systems that deliver oxygen, carbon dioxide, and nitrogen during surgery. Other duties include ensuring clean air throughout the facility, providing power to surgical equipment, and managing all pipe fitting procedures. You might work independently or under the direction of a supervisor. This is a highly specialized job with unique duties.
