PHA

PHA, or Pressurized Hazardous Area, refers to a space where dangerous materials or conditions exist, and the environment is kept under pressure to prevent the escape of hazardous substances or to control ignition risks. This controlled pressure helps contain harmful gases, vapors, or dust, reducing the chance of explosions or health hazards. PHAs are common in industries like chemical manufacturing, oil and gas, and pharmaceuticals, where safety protocols ensure that equipment and procedures maintain the proper pressure levels to protect workers and the environment.
