Uninterruptible Power Supply (UPS) is a pretty common backup power supply in industrial settings where “power failure” can lead to the loss of control systems, emergencyshutdown systems, and emergency mitigation systems.  But like ALL SAFEGUARDS we take credit for in our Hazard Analyzes, these UPS must be in our mechanical integrity program for testing/validation regularly…...

A process covered under 40 CFR Part 68 is eligible for Program 1 requirements if it meets all of the criteria listed at 40 CFR §68.10(b). One of those criteria is that the distance to a toxic or flammable endpoint for a worst-case release assessment is less than the distance to any public receptor. Are…...

Performance of the hazard assessment required under 40 CFR Part 68, Subpart B, includes analysis of both worst-case release scenarios (40 CFR §68.25) and alternative release scenarios (40 CFR §68.28). In each of these analyses, passive mitigation systems may be taken into consideration. If a tank has a “double wall,” does that qualify as “passive…...
