Cryogenic materials are commonly used in the workplace for a variety of purposes, such as refrigeration, medical applications, and rocket propulsion. Due to their extremely cold temperatures, cryogenic materials can be hazardous if handled and stored incorrectly. Cryogenic materials are stored in specially designed containers known as dewars and any employees handling cryogenic materials must wear personal protective equipment. If exposed to the extreme cold of cryogenic materials, they should receive treatment immediately to prevent permanent injury. In the event that an individual inhales cryogenic materials, they should seek immediate attention to prevent serious injury or death. This course explains how to recognize different types of cryogenic materials in the workplace and identify the potential dangers of storing and handling these materials incorrectly. It identifies recommended equipment and the standard operating procedures for handling and storing cryogenic materials safely. It also describes the most effective course of action if accidents involving cryogenic materials occur, including recommended methods for treating employees injured by cryogenic materials. The course was developed and reviewed with subject matter support provided by certified subject matter experts and industry professionals. Please note, the course materials and content were current with the laws and regulations at the time of the last expert review, however, they may not reflect the most current legal developments. Nothing herein, or in the course materials, shall be construed as professional advice as to any particular situation with respect to compliance with legal statutes or requirements.
