Abstract

This publication covers the installation and operation of food freezing and chilling equipment and associated supply systems and the use of that equipment with refrigerated liquefied gases (nitrogen and carbon dioxide). Topics covered in this publication include but are not limited to safety, design, handling, storage, use, ventilation, maintenance, and monitoring of areas where these gases can accumulate and cause hazardous conditions. General safety guidelines or information within this publication are also applicable to non-food cryogenic applications. This publication does not replace any risk assessment required by the operating company or employer. This publication does not address food safety related to biological, chemical (including radiological), or physical contamination. These should be controlled through good manufacturing practices, materials of construction, and other risk-based controls identified in other publications. Purpose The purpose is to provide minimum requirements on the design, installation, and operation of food freezing and chilling equipment and the associated supply system so that they can be operated safely. This publication will also inform about risks and their mitigation when refrigerated liquefied gases are used for freezing and chilling. These specific risks are: • asphyxiation (oxygen deficiency); • elevated carbon dioxide concentration; • pressure build up due to confined evaporation/sublimation (bursting/leaking); and • hazards due to low temperatures.
