20 Things You Will Learn
1. INCIDENT #1: Things don’t have to be big to kill you, hot water heater explosion killed 5 kids and a teacher at school in Oklahoma.
2. Warning signs that were there before the explosion that no one recognized.
3. Identifying gas valve and other fired equipment device recalls and defects
4. Considerations for the installation and inspection of safety relief valves on boilers and hot water heaters.
5. Testing and inspection requirements for the fire side combustion controls of hot water heaters, even though they look inocent and they exist in our homes
6. INCIDENT #2: Pressure vessels, (tanks), can diminish in their capacity, corrode, and release tremendous amounts of energy. This one in St. Louis Missouri killed 4 when it failed.
7. Understanding the warning signs of pressure vessel and mechanical integrity failures.
8. If you operate pressure vessels or high energy piping, you need a mechanical integrity program, places to start are provided.
9. Create policies for inspections and taking equipment out of service if defects are identified.
10. Descriptions of personnel that must be involved making repairs of pressure vessels and the types of markings that code vessels should have.
11. INCIDENT #3: Something as simple as the wrong fasteners on a high pressure steam piping system repair killed 10 sailors on a Navy ship.
12. Steam leak risks are discussed and the danger of leaks and releases in confined spaces is communicated clearly with this incident.
13. Fastener selection and bolted pressure boundary connections are vital to safe operations.
14. High energy piping systems and pressure vessels must have bolting procedures, this lesson learned provides a way to start.
15. Training staff on recognizing the important factors for high energy piping failures and bolting procedures and minimize risks.
16. INCIDENT #4: Boiler and fired equipment fuel train repairs can be very dangerous, even when people try to do the right thing. This procedural error caused the death of 6 men and a billion dollars in damages.
17. Procedures are vitally important and need to not only exist but to be vetted through processes like HAZOP’s.
18. Isolation valves need to be functional and seat leakage tested, (information about isolation and servicing lubricated plug valves).
19. Considerations are discussed for piping changes and accomodations to reduce the changes for purging errors and for complying with applicable codes for gas discharges.
20. Isolation and lockout/tagout procedures should comply with certain requirements and include training.
