A gauge hatch works as a sealed access port on storage tanks, using a foot pedal for hands-free opening to manually measure liquid levels or take samples, while its self-closing, pressure-sensitive design (with weighted pallets or seals) automatically reseals to maintain tank integrity, preventing vapor loss and acting as an emergency pressure/vacuum relief to protect the tank from deformation.
