Cryogenic handling is a critical area of expertise for laboratory professionals working with extremely low-temperature materials. It involves the safe storage, transport, and use of substances such as liquid nitrogen, helium, and argon—materials essential in numerous scientific and industrial applications. Given the risks associated with these substances, including frostbite, asphyxiation, and explosion hazards, proper training and adherence to safety protocols are essential. In this comprehensive guide, we explore everything laboratory professionals need to know about cryogenic handling—from basic definitions to advanced safety procedures. What is Cryogenic Handling? Cryogenic handling refers to the process of managing substances at temperatures below -150°C (-238°F). These substances are known as cryogens and are commonly used in various fields such as physics, biology, medicine, and engineering. Cryogens include: Liquid nitrogen (LN₂) – Boiling point: -196°C Liquid heli...
