Electrical Equipment
Electrical equipment tends to be much more susceptible to damage than process equipment and structures. Scheffey et al. (1990) indicate that operating electronic equipment can be expected to fail at temperatures as low as 50 °C. They predict permanent damage to nonoperating equipment at 150 °C and failure of PVC cable at 250 °C.
