Accidents: Prevention and Examples
As mentioned in Chapter 1, in order to have a safe operation, the system must be both designed and constructed to be safe, and it must also be operated in a safe manner. Safe operation requires excellent maintenance and housekeeping. Because new and different applications of cryogenics are frequently encountered, the possibility of inexperienced operators is always present. Furthermore, a new application might entail usage that does not have any precedent or existing applicable experience. Effective safety training is of the utmost importance, and the operators must not only be well versed in the basis of cryogenic safety but also have intimate knowledge of the system with which they are working. They must always be aware of the total inventory of cryogens and also know the location and amount of cryogen at every point in the system. Previous experiences, difficulties, failures, and accidents provide valuable knowledge that is important to anyone involved in the operation of a cryogenic system.
