Ammonia breaks down in the environment very quickly (lasting less than a week in the air). Insulation does make a difference; however, if insulation is defective or incomplete, condensation will not be prevented and corrosion will not only occur but possibly be hastened. It can also dissolve many rubbers and plastics. Additionally, in systems designed to be oil-free, internal corrosion may occur. In areas where there is machinery with components that contain Ammonia, always ensure there is adequate ventilation. to properly manage your ammonia refrigeration needs. endobj Keeping product at specific temperatures is required for industrial processes as well as preservation of various food items. <> A rise in room temperature may provide enough heat to expand the liquid, which will generate enough pressure to rupture refrigeration system components. This provides essential over-pressure protection, as cold liquid ammonia when isolated will expand as it warms up and exert pressures that could rupture the pump or piping unless relieved. The cloud produced from the release drifted from the plant, across a highway, and in to a wooded area. Regular maintenance and mechanical inspections will ensure equipment remains safe and reliable and helps to minimize the risk of ammonia accidents. As Ammonia gas is lighter than air, it will rise and can easily and effectively be dispersed from the area via an effective ventilation system. This resulted in Ammonia levels immediately dangerous to life, and a refrigeration system mechanic and two municipal employees were killed. By law these systems are required to meet minimum safety regulations that include a detailed reporting protocol… endobj Similarly, sources of heat and flame, including welding activity, should be kept well away from a refrigeration system.
