On all large construction equipment I've seen it shuts the motor down immediately. They'll probably just bypass the emergency shutoff to get it moved away.

And then never fix it.

It only needs to be moved a quarter of an inch away, and rollers aren't top heavy. A medium length 2x4 would probably provide enough leverage to pry it away from the post and pull the stop button.

I worked with a pressman who used a magnet to gimmick the safety switch on our Heidelberg 4-color press. He was super-duper proud of the facts that he could open the covers to the rollers while the press was running at full speed (10,000 sheets per hour).

Ever seen a press eat someone?

here's how I think of it:
voltage is a measure of the efficiency with which current travels through material. Impedance of material is reduced at higher voltages.
current is a measure of the efficiency with which a bunch of electrons (called a coulomb) transfer energy & do work.
watts are a measure of actual work done.

stuff people say all the time which never helped me visualize it
Volts times Amps equals Watts - if you break it down to component SI units, things actually cancel out.
various unhelpful analogies about dams, pipes, etc. find one that works for you.

real world examples:
high voltage low current systems - like the electric potential generated by rubbing your feet on carpet in winter (a few thousand volts, a millionth of an amp) - can make massive sparks that make you say OUCH but don't even twitch your muscles. 15k volts and .4ma is a stun gun: throws enough current into your meat sack to seize muscles, but not enough to kill you (usually).

low voltage high current systems - like a car battery - need a wire the size of your thumb to send an appreciable amount of juice anywhere. but there's lots of juice there for ya. enough to weld with if you have heavy leads only a few feet long.

anyway the short answer is that anything can kill you if it seizes the muscles in your heart.

thanks for this explanation lol

You can think of it that way if you want, I'm not the boss of you, but each one of those sentences is really damned wrong.Voltage is electrical potential. The usual analogy is that if you want to think of current as water flowing through a pipe, voltage is like the pump pressure. It's got nothing to do with efficiency of anything. If one Coulomb of charge is accelerated across a one volt potential, it's picked up 1 joule of energy.

And impedance of a material is dependent upon the material, it (generally) doesn't change based on the voltage; if you have a 2.5 megaohm resistor, it's going to have 2.5 megaohms of resistance no matter whether you put 1 volt across it or 100,000 volts across it or 1,000,000 volts across it (excepting if you stick enough voltage across it to make it breakdown and turn into a short.) But it does change based upon the *frequency* of the voltage.

Current, again, has nothing to do with efficiency, it's just the flow of electric charge: one coulomb per second = 1 amp.

Watts are not a measure of actual work done. Watts are a measure of power, which is the *rate* at which work is being done. Actual work done would be joules, not watts.

BEGIN INFOTAINMENT:

I can't speak specifically about this roller company, but in general the emergency stops on hydrostatically (hydraulically) controlled equipment like this just shut off all the electrically-controlled valves on the machine or dump pump flow directly to tank and all controls stop working.

Typically there are no brakes in the conventional sense on hydrostatic machines; the hydraulic wheel motors provide turning force and stopping power.

Often the emergency stops do not kill the engine, since turbo chargers on diesel engines can be costly and break during sudden engine shutdowns, and equipment owners would yell at people for pushing emergency stops, discouraging their use.

When you know that emergency stop buttons are just single-pole switches, and you know where they are wired and plugged in, it is easy to TEMPORARILY bypass any damaged or otherwise compromised button.

END INFOTAINMENT.

Hard to know what there is to worry about :

-four layers of shoring material that doesn't look tied together under the mid-outrigger;

-shoring material sitting directly on ice;

-ice is on sloped concrete;

-truck possibly tilted toward its rear so that the part under the crane load is lower than the part behind the crane load (camera angle could be deceptive on this one);

-jack at front of truck on at least three layers of shoring material that look to be the same height as its width which is in line with the load;

-that front jack appears to be perpendicular to neither the shoring nor the ground plane.

Although it looks like if the truck tipped the load would only fall into the building, if they are only lifting in line with the truck body.

http://www.oregonlive.com/pacific-northwest-news/index.ssf/2016/01/good_samaritans_who_were_hosed.html#incart_2box posted:

Two Good Samaritans have secured a nearly $100,000 settlement after they were exposed to a neurotoxin when they stopped to help a crashed semi-truck driver, then had to strip naked and get hosed down in freezing temperatures in the middle of Interstate 84.

Kortney Broecker and Shantelle Nay were traveling along I-84 in eastern Oregon near Durkee about 50 miles from the Idaho border when they encountered large pieces of metal in the road, according to their lawsuit filed in early December.

It was about 1 a.m. on Nov. 3, 2013, and the friends were worried that another driver might crash into the debris, so they stopped their car and got out to push the debris off the freeway, according to their attorney. That's when the pair noticed the overturned truck and trailer and discovered the driver bleeding and drifting in and out of consciousness.

The women had no idea that they were wading through as much as 4,000 gallons of tetramethylammonium hydroxide that had spilled along the 400-foot crash site, said Randy Oetken, their Milwaukie attorney.

They had called 911 and were told to stay put, Oetken said. They hadn't been told they were part of a hazmat scene or that the freeway had been shut down behind them and that's why emergency responders weren't coming, he said.

After waiting awhile, the women drove to the next exit for help and encountered emergency responders who ordered them to strip and so they could be doused with water, Oetken said.

"It's about traumatic as it gets," he said.

That's when the women began to realize they were suffering serious reactions to tetramethylammonium hydroxide, he said. The substance is used in the semiconductor industry to etch silicon and can be fatal to humans with direct contact with concentrated quantities.

Among the women's injuries, some of which continue to this day, according to the lawsuit: severe headaches, spontaneous vomiting, severe nausea, hair loss, eye pain, vision problems that included seeing flashes of light, shooting chest pains and constant wheezing and coughing spasms.

At the time of the lawsuit was filed, Broecker, 31, had accumulated $9,300 in medical expenses and $4,500 in lost income. Nay, 30, sought $4,300 in medical expenses. Both women also sought $200,000 each for emotional distress, pain and suffering.

Oregon State Police cited Ronald Glenn Hanes Sr. of Sacramento, Calif., with careless driving. Oetken said the driver told police that he'd taken his eyes off the road as he tried to find something on the floor of his cab. Hanes worked for LeSaint Chemical Logistics, a Texas-based company with offices in Portland.

The lawsuit was filed against Hanes and LeSaint Chemical Logistics in Multnomah County Circuit Court and settled in late December with the company, Oetken said.

Officials at the Oregon State Police, the Oregon Department of Transportation and the Oregon Department of Environmental Quality say they didn't cite the company for any wrongdoing.

A spokesperson from LeSaint didn't return a call seeking comment Thursday.

Broecker and Nay live in Idaho and were traveling back home after attending a convention in Hermiston. Two other people also were in the car, but they stayed inside during most of the incident and had little exposure.

All of the women's possessions, including their clothes and Broecker's 1997 Nissan Pathfinder, had to be incinerated because of the chemical exposure, Oetken said.

Read the lawsuit.
