    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
      @SheepInACart Рік тому +96

      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.

      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.

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.

    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
      @ronblack7870 Рік тому +11

      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.

      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.

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.

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.

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.

      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.

    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.

    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.

    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
