[@jimsvideos7201]

Aviation has a paranoia about sparks from static electricity that is an artifact of the era of high-test gasoline. It's still good practice of course but jet fuel is sufficiently difficult to ignite reliably that jet engines have _terrifyingly_ powerful igniters.

[@SheepInACart]

None of this is an artifact from a bygone era, most of the electronics regulation (and indeed even limits on smoking) is far newer than widespread use of jets. Keep in mind JetA and JetA1 aren't the only fuels used by jet aircraft, even if the most common, all engines are designed for a much larger range of fuels, most of which are more voilitile. For example even a civilian passenger liner operating out of an extremely cold region might use a "wide cut" fuel (more light distillates), and these produce massive amounts of flammable vapor in a hot climate... yet the aircraft might take off in the cold and land in the hot without changing fuel, and even if transitioning to another route it doesn't normally pump the old fuel out, it simply tops off the tanks with the cheaper alternatives. Likewise regarding luck, you can drop a match into a bucket of kersonene 99x and have it go out without incident, the concern is the one time something DOES happen.

[@SeekingTheLoveThatGodMeans7648]

@@SheepInACart The flash point of ordinary kerosene is well over 100 degrees Fahrenheit, so at most ambient temperatures there will not be a concentrated enough vapor hovering over the kerosene to be ignited by a flame in ordinary air. (It is the vapor which burns, not the liquid.) When it's really torrid out, bets are off.

[@Curt_Sampson]

Jet fuel doesn't ignite _reliably,_ but there are plenty of situations on aircraft where it will quite happily ignite outside of the engines. Quite a few aircraft have been destroyed by ignition of fuel vapours in their tanks, Philippine Airlines Flight 143, TWA flight 800 and Thai Airways International Flight 114 being just three fairly well known examples.

I was like WTF?

Had something similar happen. During my marine electrical engineering diploma we had the opportunity to visit a tanker while it was discharging.

Intrinsic safety is just one of many ways to design devices in explosion atmospheres. For pumps, lights etc it more commont to have explosion proof housing, And that means that housing of the device can handle explosion inside the machine without getting outside intrinsic safety means that even when there is arc on the device it carries so little power that would not be enough to generate explosion. Explosion atmospheres is a really wide topic and there is few more ways to ensure safety.

[@eaglescout1984]

There is also such a thing as explosion proof electrical fittings. These are conduit fittings that are filled with a sealant after wire has been pulled. From that point on, the raceway (conduit and boxes) are rated to be used in areas with flammable vapors and devices like switches are fully contained in their housing with a sealed mechanism that works them. This guarantees flammable vapors can't reach spark producing devices. If you ever seen a conduit group outside a gas station and saw where each one had a fitting with a plug, then you've seen explosion proof fittings.

[@ronblack7870]

those are called seals. they are filled with cement literally . yes they prevent burning gasses from transferring through conduit. but explosion proof housings are not airtight . they are designed to contain an internal explosion and vent the gasses through a long path that cools the exploding gasses to below an ignition temp. could be long threads on a fitting or large flat landing area of a box lid.

[@davecooper3238]

At the time I installed and serviced them the fittings were known as ‘Flame Proof’ but that was six decades ago. They may be called something different these days.

[@marvindebot3264]

That's what "Intrinsically safe" means mate.

[@ke6gwf]

@@marvindebot3264 no, IS means that it is designed to be UNABLE to create enough heat to cause ignition, for instance by using very low voltages and oversized circuit board traces to prevent overheating. Explosion proof means that in the worst case scenario, if the housing becomes filled with an explosive gas and it ignites, the case is strong enough to contain the explosion. For instance, fire department flashlights are Explosion Proof, and they have thick enough shells to contain an internal explosion to prevent external ignition.

[@gunterdapenguin5896]

Working at the docks, basically on every ship there're massive "no smoking" signs but no one ever follows them, the only time I've seen anyone get into trouble for smoking on a ship was when one of my colleagues was smoking right beside a boat full of literal explosives for the military that was going to green land, the captain was pissed and we all laughed like hell at it, he could've blown up the entire port lmao

[@TUDORMARCU16]

I guess they are mostly for legal/insurance reasons. I can't really imagine the ship's crew is strictly abiding by the no smoking rule.

[@Oilburnerful]

Thanks for the informative video. Something we use in aviation is flame arrestors. Which is just a screen with holes of a certain size around brushed electrical motors or other spark sources. Oxygen and fuel vapors can get though. But any flame that ignites inside is stopped by the screen. It's crazy to watch a fireball just stop dead at a thin metal mesh.

[@toonamimaki285]

A tanker does have a flame arrestor, installed at the mast riser, where pressure from expanded gas is released. Ours gets replaced every voyage (45~ days).

[@sgoheibhrin894]

Tankers use inert gas to dispalce oxygen, and PV (pressure / vacuum) valves to help regulate pressure in the tanks. There are flame screens fitted in the mast riser.

If you’ll let me nitpick, it’s not sparks, it’s electrical arcs within electronics that you’re describing. Great video and channel , love it.

Arcs are “small lightning” jumping through air between two metal points just as you described, but sparks are small ultra hot particles that were rubbed off of something. One is small lightning, one is a small piece of something very hot. I’m sure you know this already since it’s a common misuse of the word “spark”.

[@ZanderKaneUK]

I was looking over a Coast Guard exam/inspection the other day for work. It listed that the smoking room must be a dedicated room and its' entry exit door is not an extior deck door. Also while in port it is not uncommon to have compulsory watchmen/fireguard aboard while vessel is discharging or loading.

[@keatoncampbell820]

This is actually something I have a tiny bit of experience with! I had to install a few circuit components above a diesel tank, and my solution for preventing any sparks in the 12V system was to coat all of the circuit boards in a "paint-on electrical tape", essentially a plasti-dip. The components were selected to be overkill for their application, so they didn't resistively generate much heat, and when coated in synthetic rubber, there was no bare-metal. I know people will say diesel is incredibly inert, but I have really quite terrible luck. I actually had a small diesel fire from static discharge to the steel tracks of a bulldozer that I had spilled a little bit of diesel on while refueling it. My boss did not believe me until he saw the fire was only a few inches tall, nowhere near the actual diesel tank, and only my fingertip was burned. I have spontaneously combusted more than once, and never to any injury... yet

I remember Kaiser-class oilers, if you wanted to get to the main deck forward of the house, you had to go via the 01 level, because there were no doors at all between the tank deck and the after section of the main deck, for just this reason. And positive pressure. It's a lifesaver, for sure, but there's nothing quite like a ship that gets passive-aggressive with you, every time you try to open an exterior door.

[@SeanBZA]

@@cockatoofan Part of the EEX rating for the parts is to make sure of that, so you will find things like air lines are made with carbon loaded vulcanised rubber, as that is static dissipative, and that you will have a lot of hydraulic systems there as well for power. No PVC or nylon air lines, and the light fixtures are very heavy to remain intrinsically safe, even though they have electric power, it travels to the fixtures in heavy steel conduits, and inside the conduits the cable itself is steel wire armoured. Any junctions are also in EEX rated metal boxes, with steel cable glands.

Your car door latch in fuel stations are problematic because of static electricity discharge, not because the mechanism itself generates sparks.

That was a truly awesome summary of this phenomenon. I love how you explained the psychology behind it, as well as highlighting how often times such safety signage will choose to call out the most common single or few problem sources so that the information can be conveyed quickly and with gravitas; instead of trying to address a large number of possible problem sources which would require lots of verbiage that most people wouldn't read, and which would limit the ability to express such concepts in an attention-grabbing manner. There's so much thought that goes into designing safety signage that most people never consider, particularly when it comes to signage meant to inform the [untrained] general public about very specific or obscure hazards. And the way that you were able to concisely explain all of this while remaining entertaining was really well done - keep up the great work, mate 👍

In that case, the crew area will be more vulnerable to the incoming waves.

[@Curt_Sampson]

That creates further problems and expense, though. The propeller and rudder, for fairly obvious reasons, have to be at the rear of the vessel. It's a lot easier to put the engine back there as well, otherwise you need a way to transfer power from the engine in front through the entire ship back to the propeller and rudder, as well as control signals for the rudder etc., which adds additional things going through the cargo area that could generate heat and ignite the cargo and increases risk of a failure of those systems that could, e.g., leave the ship drifting on to rocks or wherever. You get the idea.

[@giantdwarfulf]

Actually my shipping company got the great idea of building new tankers with accommodations forward. Worst shit you can imagine. Not only because of stability but also because the engine is still aft, when the weather is bad nobody on board is sleeping because the anchors are super loud, the whole safety concept is stupid with the free fall boat being aft. Also they got a dual fuel system (lpg and regular fuel) which is super stressful to maintain, especially for the pump man who constantly has to make used up tanks gas free and cool them down again.

An inconsequential detail, but the pneumatic tool first shown at 4:11 is attached to a condensate drain - the air output is on the right of the regulator, level with the input. The little port on the bottom is for bleeding out pressure in an isolation situation, or excess of air tool oil (or moisture, assuming an air drying system is not present.) A few years ago, our plant air dryer went down for about a week, and all week I was constantly going around playing with these little drains (from a handful of different manufacturers that all had different ways of opening them...that was fun) to get the moisture out. That's when I learned what those things were for. You _could_ attach something there, but they're not designed for that and would be a little cumbersome - an addition to putting undue strain on part of the equipment not made for it.

And that means you don't need to touch grounded metal things to uncharge yourself if the floor is grounded. (which would be the case with ships i guess)

[@TheNinjaRider]

Cool that you used a Stolt-Nielsen tanker as an example😊

[@enginesimul]

A really awesome video. I would like to ask how do ships discharge static electricity

[@the_eni]

I work on a small (85m long)chemical tanker in Germany . We have to use tool that have an Ex certificate.

[@andre-jm8jn]

Fantastic video, very well explained. As a Yacht Surveyor I compliment you for your work! PA YACHTING

[@913WildCat]

What about exposed metal? In some ships there are brass fittings to prevent sparks. Does this carry over to heavy equipment on deck, as well?

[@aggese]

I would assume that the crew use boots that are simular to ESD safe shoes used in electric manufacturing as those helps with bleading of any static charge in a safe manner

[@michaeldebidart]

That “No Heavy Petting” sign has that “I’m gonna flip the bird in the class picture, no one will notice” energy

[@stevenneiman1554]

It's kind of interesting hearing about this as someone who frequently works in ESD-controlled environments, because in some ways they're a much deeper but narrower set of restrictions. You probably won't find people smoking in a typical ESD-controlled area but it's not against ESD policy and there are similar things like soldering irons which have to be available, but the protections against sparks are much tighter. In an ESD area, everything is designed to be conductive and not generate static electricity, technicians have to wear conductive coats and straps on their shoes that make them viable paths to ground (though that's suspended around high voltage, since safety is more important than preventing damage to product), and there are even devices designed to fill the air with ions that can settle on and counteract anything that picks up a static charge.

[@stephencarey5074]

Actually, you cannot light gas or petroleum products with a cigarette (unless you're in a Charles Bronson movie). However, the match that lights your cigarette can, as can dropping it on a rag which causes the rag to smoulder. The reason is that the ash on a cigarette end acts as a flash arrestor. Our ships had NO SMOKING and underneath that NO NAKED LIGHTS, which probably leads onto heavy petting... Good video by the way.

[@ThePheenixKing.]

Grear video! I just happened to spot a spelling error roughly at min 6, where the writing scrolls across the bridge wall, intrinsicall safe tools was misspelled.

so the 'danger zone' would 'take my breath away'? sounds kind of familiar...

[@graememceachren1118]

The zone we are entering will be one of danger.

[@gert-jantwaalfhoven9755]

Depends a bit on the cargo, but the hazardous zone barrier is usually three meters after the forward accommodation bulkhead

[@erikaitsumi3852]

I built air tight aluminium housings for electronics to go on oil rigs

[@ant7936]

We had one designated room for smokers, when we were in Port, transferring oil. At sea, we were allowed to smoke in accommodation.

[@UserUser-ww2nj]

The cut off point from the danger zone and "safe" zone is not always at the start of the accommodation block , it can be part way along and as for winches they are hydraulic so no electricity , even things like vales for controlling the flow of oil are hydraulic. The company i worked for had two large gas tankers , i sailed twice on one of them . Joined it one time in Boston in the states , one guy decided it would be a good idea to smoke a cigar on deck , he was on a plane back to the U.K next day

[@bouli3576]

About the winches : do they have friction brakes ?

[@thegoat3336]

I've always known that but I still don't trust it

[@miscellaneous.7127]

Just finished my Basic Tanker Familiarisation course and then this pops up!

[@mikmik9034]

c. 1980, Neighbour who was a Tanker Merchant Marine, said Even carrying a cigarette lighter was banned. ALL their tools were Bronze.

[@7grims]

Is there a channel like this, but for airplanes?? I started watching these videos casually, and got addicted to all the interesting facts presented. Now I thirst for something similar for planes (and or other topics).

[@RFC-3514]

You're more likely to get a spark off a polyester blend sweater than off most portable electronics. This was amply demonstrated a few years ago when there was a series of fires at petrol stations and they started by blaming people using mobile phones despite the "no phone" signs on pumps, then ran some tests and realised they had all been caused by sparks generated when the driver touched the car's outer metal casing after accumulating static charge due to their clothes rubbing against the seat. It also disproportionately happened to women, because they were less likely to touch the metal on the door as soon as they got out (which would discharge the static before going near the tank) and because they tended to go back for their purses (which resulted in a second point of contact with the statically-charged seat). Maybe that's the real reason why some old sailors used to say it's bad luck to have women on board. And we though they were just misogynists. :-P

[@jackripper9810]

Now the big question - is the offset and size of the NO SMOKING sign on the accomodation block normed? I could see that together with any front mast being used together by another to determine wether the tanker is on course for collision...

[@outlawdingo3020]

Having worked in a port (we go into the hatches of the boats) all if not most ships will have no smoking signs, and we can’t smoke on the warfs unless we go to designated areas by the crib huts or in the hatches of the boat themselves (security cameras and bosses ect can’t see us). talking about all ships in general and it was a mining port with general cargo capabilities like your average port

[@aslavdogg]

My grandfather used to work on a large oil tanker on romania (MT Independența) that ended up sinking due to a greek ship that smacked into it, but thats not the point, the thing is he told me, a bulgarian oil tanker, had exploded due to a cigarette (it was on the stern helipad) But back on those days safetey were different ig, because of this NO SMOKING was allowed in any size of the ship, he told me they saw a guy smoking... On the next port he did not leave with the oil tanker

[@nixd0rf356]

great video

[@captainevenslower4400]

I have a wonderful vacation photo from Italy where a small tanker was refueling our ferry in the port and you can see a worker smoking directly beneath the huge sign.

[@kaihorstmann2783]

„No Smoking“ is just the name of the shipping line. Like the retail chain „Sale“.

[@offichannelnurnberg5894]

Sale was never that popular in France, oh I can't imagine why🤔😁

[@arsinclair]

I'd be A-Mazing to hear about various real-life incidents related to smoking on board that led to such measures.

[@panc8ke324]

Good info, cheers. FYI @5:54 "instinsically safe".

[@timfagan816]

Cracks me up, that the lads at work are not allowed to smoke on the wharf while they're wrapping wires around the logs, for the ship to shore crane to deliver heaves of logs into the hold. But they can quickly jump aboard the ship for a quick smoke break and then go back to work! We always see the ships crew flick their cigarettes into the hold full of dry timber. 🤣🤣

[@Fabius11k]

Nice video :)

[@347Jimmy]

Crew members are also strictly forbidden from spontaneously combusting, though this is discouraged in most workplaces

[@whateverrandomnumber]

As a maritime and harbor pilot I say: “Explain that to Indian captains”

[@Unimog1600]

One issue, that does come to my mind right now, is rust removal. Ships tend to constantly corrode due to a lot of steel present and the salty air on sea. There the rust usually has to be removed frequently, every few days especially when on sea, to not let it get out of hand. Even if the tools are air-driven, they still produce sparks when removing the rust and touching bare metall. How is this kind of work performed on ships with flammable or explosive cargo?

[@SeekingTheLoveThatGodMeans7648]

What kind of metal on what, would be my first question. Brass on iron or steel might not be spark prone.

[@taiyoqun]

Or beryllium tools maybe. They don't spark either, and are non magnetic

[@rustteze]

No such work to be carried out in ports when the risk is maximum, at sea however with a wind of usually 20 kts and all tank fully secured, purged of oxygen.. And flame arrestors on venting... Such sparks don't mean much

[@Unimog1600]

@@SeekingTheLoveThatGodMeans7648 I guess it could be enough to create sparks, if loose metall/rust parts are scrape over the still solid parts by the tool. Independent of the material of the tool itself. But I don't have experience with that.

[@Unimog1600]

@@rustteze I would guess the same. But I'm curious whether there are actually regulations or guidelines that take this in account. It seems to me that a lot is regulated quite strictly in the nautical business, so I guess that there might be one for this too.

[@baystated]

What kind of precautions are there against naturally occurring electrical discharges. Not just lighting but aren't there phenomenons like st. elmo's fire that are zappy?

been 2 off , ch.off.and captain on many chemical tankers for bout 28 years. all apparatus carried on board are , legally, supposed to be intrinsic safe , like cell phones , latops etc, sometimes i had to refuse boarding to some officials whom thought that the rules didnt apply to them. like smoking on the gangway. using normal cellphones etc.

[@morganahoff2242]

5:56 "Instinsically safe." Ha ha, close enough!

[@CrankyPantss]

That was very interesting. So if they don’t have to obey the NO SMOKING in the crew area, does that mean that they can ignore the NO HEAVY PETTING in the crew quarters, too,?

[@Nate-bd8fg]

Just need a heavy petting room

[@stanislavkostarnov2157]

as someone who occasionally had unprotected micro-electronics around the house, I want to say that anti-static paranoia is quite something, a person/body generates electricity in surprising places and ways!

[@charliecharliewhiskey9403]

Even though most people haven't had training, I'm pretty sure they also understand that if they see a sign that says "no smoking", it actually means "don't do things that use fire". Like, gas stations have "no smoking" signs, but people also wouldn't have a BBQ in front of one, because they understand "the risk from smoking here is the flame, so flames are a bad idea". "No smoking" is a shorthand used all across society to mean "don't use hot stuff here", using the same concept of "eliminating the most likely source of ignition".

[@rayoflight62]

The great advantage of tanker ships, in relation to electrostatics discharge, is the presence of salt and humidity everywhere. They discharge any static electricity buildup long before the potential can increase to the level it can generate a spark, or a dark corona discharge. Imagine a place with opposite conditions, as an Artic station, with -25 °C during the day, with almost 0% relative humidity; a single walking step on a plastic floor donning rubber shoes generate a one-inch long spark. Smoking tobacco is at about 900 °C. Vaping is safer because the heating coil tend to be below 200 °C but, should the cotton wick dry up, the heating coil can get red hot at the same 900 °C of burning tobacco...

[@Dhalgrim]

“What about in port?” Like when you have an FRSU in port and mountains of coal on the pier that are smoking 🤣 And yes I am speaking from experience (port operator/traffic control). But luckily those were seperate. Recently we got loads of coal for the first time and the stevedore company didn’t account for coal starting to self ignite when it is piled to high and not shifted around frequently. It is sorted now and the FRSU is only being refitted here so no Gas in it. It was still a big concern for us as it wasn’t clear if we’d be the port for the regasificatiob or not.

[@runrabbitrunracing]

Intrinsically safe only applies to low power devices. Motors, pumps and other electronics will be protected by other protection methods of which there are many. Flame proof enclosures, encapsulation, over pressure, increased safety etc etc

[@firetruckstrainsicecreamtr4971]

I saw a tanker in the cape cod canal just now and I thought of this video and it was the Iver porsepreity tanker ship

Iv been loading ships for years and we had intrinsically safe radios, control boxes and breathing apparatuses only to have a crew member smoking next to you.

[@rdbjrseattle]

You can’t have open flames on cargo deck or where fumes might be ignited. There might be special compartments on board.
