NTSB Investigation - San Bruno Pipeline Explosion

[@mattmayo3539]

Shortly after this accident. Photovoltaic systems and power storage systems became extremely popular in California. Every house that was rebuilt now has solar. It’s a quiet middle finger to PGE. Done giving them money.

[@getdusty1]

Extremely well made production!! More of these should be made available to the public. As a retired control centre operator, I myself was behind the pressure "controls" when Line 10 encountered a five foot rip in the 16 inch crude oil pipe. I know personally what it is to be asked questions by the NTSB about the incident. They were not only thorough, but fair!! More of these need to be made public. Air crash investigations are, why not pipeline ruptures??

[@cookielapaz8927]

What an unusual world we live in where PG&E get rewarded repeatedly for their incompetence and greed. They can't maintain their gas and electric lines and have caused damage to private property and human beings yet Governors Brown and Newsom have waived hundreds of millions of dollars in fines and keeps rewarding them millions of dollars in rewards for the poor job they've done. 😢😢😢Lord help us and protect us from PG&E and our government representatives and supposed regulators🙏🏻

[@sherylbeasley4938]

I remember that and could see the huge smoke cloud south of San Bruno in Cupertino, we first thought a jumbo jet had crash there because it was close to SFO air port. The flames were so massive that they were using air tankers to drop retardant on the surrounding area because the fire fighters and rescuers couldn't get near the areas surrounding the fire,lots of houses and cars just spontaneously combusted from the intense heat blocks away from the flames.

[@Cemental]

Nice production. Thank you for making this available.

[@PublicMenace22]

Thank you NTSB for not being corrupt and exposing the truth, i know you guy probably had "offers" to keep quiet, San Bruno appreciates it

[@cookielapaz8927]

NTSB is just as corrupt as all other government agencies. We never heard the name of the person who made the decision to increase the pressure in that pipe that day which was more than it could handle. CPUC analyst Jackie Grieg investigating PG&E underground gas pipielines was killed when that pipe blew up in her backyard. A coincidence?

[@MrCanuck78]

It's so sad they try and blame a 70 year old pipe , instead of their monitoring capabilities and human error .

[@ferky123]

It should have held to 400 psi and it let go at 300 something. Also the pipe was supposed to be seamless and it had a big seam in it. Also it was made out of short sections which is a no no. It should have been a single length of pipe with no seams and no sections. This section was put in to save money and use up scrap.

[@cntslesfabrication]

This company has done more than 200 billion dollars in damage over the last 15 years and killed so many people because they don't keep up on maintenance on their pipelines and power equipment and they get away with murder. After one of the incidents the CEO was fired but received almost 10 million dollars in severance package. When everyone else who lost family members and everything they owned was destroyed it's sickening what they have done. They got bailed out by the California government in the last 8 years. They just filed for bankruptcy after the 2017 fire that there power lines caused and last year it happened again from there power lines the "campfire"

[@cookielapaz8927]

This was all bs to say a pipe that lasted 70 years was flawed. The CPUC did their own independent research and found someone increased the gas in the pipe. But couldn't identify the person because they said there was a shift change. I guess there's so much chaos during a shift change anyone can blow up a 70 year old pipe and get away with it.

[@jfs70ss]

I saw this video from beginning to and they blamed PG&E for improper welds which were not acceptable even by 1956 standards when it was installed and lack of pressure testing even though it was not legally required. No one is laying blame on the Pipe itself, but those who installed it and their lack of safety and oversight protocol. Monitoring an unknown compromised Pipe installation from 54 years prior would not have prevented this unfortunate accident. Pressure testing it would have however they were not required by law to do so. Sadly, until accidents happen and people die, only then are such laws initiated.

[@mylovesongs2429]

Almost 8 years later, a natural gas explosion has struck the Boston, Massachusetts area, igniting 100 homes.

[@NicholasLittlejohn]

You were lucky! "Natural" gas is so toxic and dangerous.

[@jpeg.600x2]

wtf, that's crazy

[@rickyoceans2943]

Good production. I remember when this happened, and i live in san jose. What craziness that was!

[@nightwaves3203]

Add automatic shutdown during earthquakes then inspections with pressure testing. There's also a need for evaluating ground slippage and deformations along the grounds path. Beside the over pressure I'd venture that long length of pipe had stresses on it from shifting grounds after numerous earthquakes.

[@MohammadX101]

san Bruno does not have numerous earthquakes. last one they had was in 1989 and why would that stress only that section of the pipe and nowhere else in the bay area?

[@maymaystudio1702]

its disturbing that ive been close to multiple disasters caused by pg&e's negligence. First with my mom's house a short walk away from the pipeline explosion and then again with my dad's house being dangerously close to multiple wildfires cause by pg&e power lines...

[@mokenetgumshoe1064]

Pg&e should have had employees responsible for lying and bullshiting their work, plus those who failed to give proper oversight, tried for manslaughter, and more. Criminal corporations must be punished.

[@kevinmarshall3198]

The pipe was installed in 1950. They are all probably dead.

[@jaysmith1408]

Never have, never will be. Going along with “PG&E records said” or “a representative said” is ridiculous. Their reliability, safety, honesty, and track records are abysmal.

[@jimbeatrice3439]

PG&E is too big and needs to be broken up. Since San Bruno their equipment failures led to the demise of Paradise California. Do and Will NEVER trust PG&E and that pipeline runs two houses down from where we live..

[@organbuilder272]

NTSB has to import people from India to assess situations. Guys who can't even pronounce English properly? But regardless of where he was from he uncovered a lie so serious that the result is tantamount to murder. The people who ordered that pipe section, who used it and authorized it should all be in prison forever. When are the citizens of the USA going to make public and private officials responsible for their actions. Get off your apathetic asses and do something people. Regardless of how long ago this tragedy was, stupidity, careless and inefficient operations are STILL going on, including these mass shootings, and NO ONE has the courage to stand up and do something about it.

[@getdusty1]

One of these needs to be done about Enbridge's Line 6B rupture into the Kalamazoo River, or do you only do these if people die??

[@tclem44]

At 9:48, narrator calls this a "tragic accident"! And again, at 18:50, the chairman of the NTSB calls it an accident! It wasn't an accident! It was a horrific event, but not an accident! People who should have known better did not do their jobs properly or correctly. They caused this. People died due to incompetence and/or corruption!

[@jenniferpearson9654]

I saw the ball of flame from my house when my nextdoor nabior told use we quickly evacuated Lukly my hose wasn't to close

[@Kevin-wj4ed]

Out of sight out of mind!!!!!!!

[@Orlando_Rails]

My property was on this pipeline. What did pg&e do? They just cut trees

[@Mbaldwin437]

This mess is on somebody's conscience,they knew verywell it was a cob job,could of used one solid section of pipe to remedy this back in the 50s,but instead pieced it all back together and buried it hoping it would be good.

[@Alucard45000]

I'm so happy Norway don't use gas.. This is horrifying..

[@UCDScontrolroom]

Gas and Liquid pipelines are regulated by PHMSA and must have a control room management plan, addressing controller workload, fatigue, alarm management, and HMI design. Ian Nimmo of UCDS has been working with customers for many years helping them develop operational excellence, incorporating all of PHMSA's regulations. It's a good thing to see the pipeline companies finally doing this, even if though they are being forced to do it, it's in place to save lives.

[@NicholasLittlejohn]

Never live near a hazardous natural gas pipeline. Look for area warning signs on poles.

[@Kevin-wj4ed]

Tombstone technology!!!!!!!!

[@mattmayo3539]

In the Bay Area it is now extremely popular to have an all electric home that is equipped with solar panels. Far less volatile and dangerous that plumbed gas.

[@MrBobity]

Good job NTSB, we need to know...We just had a pipeline explode at a school in the Twin Cities..I know you find the cause..

[@MohammadX101]

this report demonstrates that it is possible for the PG&E to cause gas explosion and hence "wildfires" on any section of its gas lines, remotely from their control stations, simply by opening the valves at one end of the pipe and restrict it at the other, hence increase pressure to a targeted section. watch from 9:50 to 10:50 especially at 10:24 "...somehow..." means deliberately, the investigators don't want to specify for possibly conspiracy reasons. why did it take the pg&e more than 1 hour to shut off the valves? control room should've called the pg&e 800 number and one of their trucks would've stopped by within 10 minutes. This should explain why houses and cars completely burn but the trees are intact because the fire starts from the gas heaters and kitchens and moves outward eventually going out without burning all the trees outside

[@tm13tube]

The companies don't worry about the pipes and leaks. They want the money flowing through. I don't understamd how they can do this.

[@Treblaine]

By taking the pipeline offline and filling it with an incompressible liquid like water then the pressure test could be conducted quite safely as any burst would cause the pressure to immediately drop without an explosion.

[@TheTruthSeeker756]

Does a pressure test weaken a weld?

[@Treblaine]

@@TheTruthSeeker756 A single overpressure tests can strengthen a pressure vessel. This is the cause of the de Havilland Comet disasters, they did an overpressure test on an airframe to confirm it was strong enough BUT to save money they repeated the "pressure cycle" test on the same test airframe. It seemed to take a huge number of cycles of pressurization and depressurization for fatigue cracks to form but this was only on an airframe that had been overpressured which caused work hardening. When they repeated the test with a a normal airframe the pressure vessel ruptured within a tiny fraction of the cycles.

Quality control gets expensive. Some cocaine and hookers for certain politicians and regulators is much cheaper. Unfortunately these don't make the public safe.

[@mattmayo3539]

I lived in San Francisco and worked in foster city just south of San Bruno. I was driving to work on 101 southbound and saw the explosion. I thought we were under attack. I drove straight to my parents house an hour and half away in the east Bay Area.

I'm glad they fixed the flickidy so it wouldn't fleeb again.

[@Trxustzed]

Nice production

[@Fatboy53]

No mention of City of San Bruno installing a sewer line next to this section w/o notifying PG&E just prior to the explosion. Plz tell the whole story as it is in the ~200 page report. Yes PG&E sucks but tell the whole story including no one there knew exactly where the iso valves were and hadn’t turned them in years. So sad ppl died.

[@thejasonknightfiascoband5099]

5:40 keytaco aboil saw 7-11. I had to watch that part 3 times so I could figure out wtf he was saying

[@small_ed]

Why would the NTSB be involved for a pipeline explosion resulting from an alleged gas leak? Perhaps because something indeed airborne caused the explosion, like a missile? I wouldn't be surprised if directed energy weapons were additionally used considering the inexplicable inconsistencies of destruction to the neighborhood.
