Flammable liquid Presure vessel and piping inspection
Flammable liquid Presure vessel and piping inspection
(OP)
Are there any mandatory inspection intervals on piping pressure vessels and equipment containing flammable liquids by OSHA Standards? If so what is the publication reference? I have looked through OSHA 1910 but I can`t seem to find a mandatory time limit on inspection intervals or the documentation requirements.





RE: Flammable liquid Presure vessel and piping inspection
I have listed a few below.
Standards that include inspection information are incorporated by reference as specified in Sec. 1910.6:
National Fire Protection Association Standard for Drycleaning Plants, NFPA No. 32-1970;
National Fire Protection Association Standard for the Manufacture of Organic Coatings, NFPA No. 35-1970;
National Fire Protection Association Standard for Solvent Extraction Plants, NFPA No. 36-1967;
National Fire Protection Association Standard for the Installation and Use of Stationary Combustion Engines and Gas Turbines, NFPA No. 37-1970;
ASME Boiler & Pressure Vessel Code

This American National Standard is a required code in many jurisdictions of the United States and Canada. Provides rules and guidelines for inservice inspection of boilers, pressure vessels, piping and pressure relief valves. Also provides rules for the repair, alteration, and rerating of pressure-retaining items and repair of pressure relief valves. Serves as a manual for inspectors to help maintain uniform administration of boiler and pressure vessel rules. Now also includes "VR" requirements.

RE: Flammable liquid Presure vessel and piping inspection
Each owner of a facility containing piping/equipment transporting, processing and or storing flamable liquids must develop a plan for inspection. OSHA has regulations about "Process Safety Management" planning, regulations and guidelines. Your state may also require developed and implemented plans....
The plan must take into consideration the specific liquids processed or stored and the unique aspects of your facility.
Having said that, be aware that PSM plans for most piping systems and tanks/pressure vessels involves (as a minimum)annual visual inspections for external corrosion and leakage. Tanks must also be periodically emptied, cleaned and internally inpected. Typical intervals for internal inspection (after the original commisioning inspection) are two to five years.
The American Petroleum Institute has published guidlines (API-579)on system inspection and "fitness for service".
You may want to consider having an outside contractor perform this service....

RE: Flammable liquid Presure vessel and piping inspection
High pressure steam vessels running at 2000 psig and 500f are typical in many plants, are there any inspection intervals set by osha or any goverment agency. If a pinhole leak would develope it would be able to cut a man in half........ Thanks for your help
RE: Flammable liquid Presure vessel and piping inspection
According to my best understanding of the convoluted OSHA PSM situation......
To directly respond to your question, OSHA does not directly specify inspection intervals.....and, yes the owner is able to determine his own intervals "based on the characteristics of his specific system"
Several organizations offer thier services to plant owners in development of a PSM plan.......and, yes this does seem like a loophole to me too.....
Based on the description of your "high-energy" systems, you should know that some engineering firms offer software to help in the determination of PSM inspection intervals.

The Canadians are more straightforward......this TSSA guidline is interesting.....

These people are still developing guidelines....

Are you asking if lies, bullshit, corruption and MBAs will always trump honesty, virtue, common sense, and personal reponsibility ?
OF COURSE !!!!!!!!!!!!!!
I am guessing that you are either a young engineer or someone who is new to the site........ Do you think that your reasonable observations of conditions that have existed for many years and compliance with national and state law is new to the owners and operators of the facility ?
OF COURSE NOT !!!!!!!!!!!!
These people are probably aware of dangers that you haven't even discovered yet !!!! They are graduates of some state school somewhere and are hoping that they can get to "bonus time" or retirement before the big explosion/fire !!!
Think I am a little crazy or bitter ?
Go to www.csb.gov and start reading the reports......Read about systems that were run beyond thier design capacity or by "contract employees" (read "poor mexican") who get burned or killed in the process......
Read about the MOTIVA sulfuric acid tank disaster and tell me how many pieces that the welder was blown into when he struck an arc near a tank vent. You can also read about the state govenor who was so "outraged" that she wrote a two page letter to the plant manager because of the accident.
There is plenty of money to hire slimeball attorneys after the chemical plant accident......but no money to prevent it
Want more ? Purchase and read "What went wrong ? by Trevor Kletz......... a fine accident anthology
Watch your back, LAMAN.......most MBA management has a tendency to try to blame those that identify a systematic problem after it has been uncovered and punishment is immenent....
My thoughts only....

Here in Australia, the philosophy is definitely a "hands-off" approach to safety in the petrochem industry. Our governments do not want prescriptive regulation, but go for a performance-judged regime.
Inspection still occurs, but operators are free to design and run plants in their own way. The governments will not tell them how.
Cheers,

Agreement settles government lawsuit
By JEFF MONTGOMERY
Staff reporter
12/16/2003
State regulators on Monday won unprecedented oversight of safety and maintenance management at Motiva Enterprises' Delaware City Refinery, settling a government lawsuit over repeated accidents at the complex.
Under the pact, Motiva Enterprises agreed to a three-year, state-supervised overhaul of programs at the Delaware City Refinery. Motiva will pay for independent audits of the company's progress, with reports delivered to the state by an engineering and safety contractor.
Gov. Ruth Ann Minner demanded the concessions in 2001, after a deadly explosion and fire in a sulfuric acid tank at the refinery. Subsequent investigations led to the consent order filed Monday in Chancery Court that gives Motiva from six months to three years to complete 15 tasks recommended by the same engineering consultant who will audit the work.
Early priorities include completing overdue inspections and repairs, with provisions for automatic daily fines of as much as $2,500 if Motiva misses deadlines.
Delaware officials said they were unaware of any other state where government safety oversight had reached as deeply into refinery operations.
"Having it filed with the court sets a precedent, as far as I know. This is the first time I know of that a state has entered into an agreement for plantwide inspection and maintenance," Minner said Monday.
Motiva officials said the company already has completed a number of the recommendations.
"We remain committed to improving the plant's safety and environmental performance and are doing so" through an industry certification process and other programs, refinery manager Frank Wheeler said. He said the company has made some progress but there is still more to do.
State regulators based the order on a sweeping "mechanical integrity" review commissioned by the state and completed earlier this year by Houston-based ABSG Consulting. ABSG found the Delaware City Refinery was "below the industry norm" for proper upkeep and operation of its equipment.
Motiva has faced a string of lawsuits and regulatory sanctions since the July 17, 2001, explosion that killed a Pennsylvania man and injured eight other workers. More than 1.1 million gallons of gasoline-laced acid spilled during the accident, later blamed on neglected maintenance and overlooked warnings.
A civil case seeking more than $50 million in penalties for federal and state air and water pollution violations is pending in U.S. District Court. Motiva, the state Department of Natural Resources and Environmental Control and the Environmental Protection
Agency are in settlement talks in that case.
Problems persist at the plant, however, with Motiva reporting the failure of a major pollution control system and excess emissions of hydrogen sulfide, ammonia, carbonyl sulfide, hydrogen cyanide and sulfur dioxide as recently as Sunday.
"They've been trying. They've had some problems but they continue to try," Minner said. "We need to make sure that we stay on top of it."
Provisions in the latest settlement include:
* A six- to 18-month deadline for completing higher-priority tasks, such as safety training for workers and development of new procedures for temporary repairs and reporting on inspections of equipment that operates under pressure.
* A three-year deadline for other changes, including development of safety-related record-keeping and monitoring programs.
* Automatic penalties ranging from $300 to $2,500 per day for missed deadlines.
* A $30,000 payment to the DNREC for oversight costs.
State officials said in 2001 that the acid tank explosion was a symptom of misplaced corporate priorities - "too much emphasis on productivity and not enough emphasis on the safety of that refinery," Minner said. Weeks after the explosion, she said Delaware would consider a shutdown if company officials balked at reforms.
"The baseline here was industry standards," said David Small, deputy DNREC secretary. "This is really about the oversight and administrative and management system that the refinery has in place."
RE: Flammable liquid Presure vessel and piping inspection
Thank you for the update to this thread.....
I believe that the dates tell the true story....
The MOTIVA disaster occured in July 2001, a man was killed, the acid tanks were in terible shape for a long time "Governor Ruth Ann's" statement is dated December 2003.
The state of Delaware turns a blind eye to all operations until there, of course, there is a vote threatening disaster....
Until a politician might not get re-elected.....
Then the slimeball/lawyer/politicos get "outraged at the situation and demand change !!!!!"
The politico's wrath, of course is directed ONLY AT A PARTICULAR COMPANY and ONLY FOR A SHORT TIME
The obvious, common sense solution,......third party (or state)review of safety is never selected. More civilized countries than the United States (like Spain/Germany/England) implement a third party review
There have been other accidents at other refineries/process chemical plants involving explosive vents....workers have been killed/dismembered in the past......this will continue in the future
same as it ever was....same as it ever was.......
