At 11:00 a.m. on May 23, 2019, an employee removed a regulator from a chlorine gas cylinder to perform yearly maintenance and repacking. When the employee attempted the close the shutoff valve, the valve malfunctioned and stopped turning while still slightly open without the employee’s knowledge.

Two workers were injured on an offshore platform while installing a skillet, the steel circular joining plate inside a section of piping. The incident occurred while the workers were on scaffolding and unbolting a 10-inch flange (Figure 1). After determining the skillet was the wrong size, the supervisor instructed a third worker to join the
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
I use propane as a raw material in my manufacturing process. I lease the tank from the propane supplier. The supplier does all the maintenance. My staff never work on the equipment. What should I do?
Which states have been granted a delegation of EPA’s authority to implement and enforce the risk management program rule?
Certain exemptions may apply to determine whether more than a threshold amount of a regulated substance is present at a stationary source under 40 CFR Part 68. One exemption is for regulated substances that are “manufactured, processed, or used in a laboratory at a stationary source under the supervision of a technically qualified individual as
I recently submitted my five-year RMP update required by section 68.190 (b)(1) and included my accident history for the previous five years. Two months later, we had another reportable accident. Do I have to do anything to revise my RMP?
If an owner of a stationary source leases propane tanks from a gas supplier, who is responsible for preparing and submitting the risk management plan (RMP) addressing the propane tanks?
I run a wastewater treatment plant that is subject to the risk management program regulations in 40 CFR Part 68 for a covered process containing chlorine. A chlorine scrubber system at the plant is designed to prevent any possible releases from reaching a toxic endpoint offsite. How does this active mitigation system affect my selection
The Risk Management Program regulations require owners and operators of stationary sources to coordinate their response needs annually, or more frequently if necessary, with local emergency planning and response organizations (40 CFR §68.93(a)). Are stationary sources responsible for determining if coordination activities should occur more often than annually?
