Here you are in this post claiming to have some expert knowledge in the collapse scenario because you worked with piping, does that make you an expert?
Wrong dipshit.
I worked in an engineering firm for many years. Piping design was just ONE of my jobs. I was an on-site construction supervisor for many different steel mill projects INCLUDING blast furnace renovations. I did rolling mill studies. I designed hydraulic systems for casting plants. I did on-site damage assessment for disaster sites including the Shell Oil site in Belpre, OH (Belpre blast alarm ignored says Shell-14/11/1994-ECN) and at the IMC/Angus nitroparaffin plant in Sterlington, LA (Belpre blast alarm ignored says Shell-14/11/1994-ECN). I did design work for the Army Corp of Engineers on the Toole, Utah Chemical Agent Disposal facility (Tooele Chemical Agent Disposal Facility - Wikipedia, the free encyclopedia). I was a project supervisor for the installation of an Oxygen pipe line in the River Rouge steel mill in Michigan. I've done structural, architectural, and mechanical design. I've done HVAC design.
So yeah, I say I know what I'm talking about.
What have you done?
you are not a engineer
Your point? I have worked with enough structural engineers to know you and your ilk are nothing but spineless pussies who run from every tough question and instead post youtube videos because you can't think for yourself.
Just like the idiot Mr. Jones who tried to post bullshit that was COPIED from another site yet made it look like he/she knew the subject. Didn't give a link nor posted it as a quote. What a dope.
Typical dishonest bullshit.
