Esso Canada to Stop including PRIST

[Bushav8er]

Heard today that Esso will stop putting PRIST in Jet fuel, date I heard was by Dec1, 09. Liability was stated as the reason. Apparently they are using up that already in the system and will advise all operators shortly.

Thoughts?

[paydaymayday]

I haven't heard anything like that and we get our contract fuel from them. I wouldn't imagine that they would do something like this, especially here in the north.

[Bushav8er]

Heard it from our Esso guy today as a 'heads up'.

[2.5milefinal]

Will they still add it in if you ask for it? Or are they getting away from it all together?

[Bushav8er]

He said they have an memo telling them (fuel handlers) NOT to touch it.

[2.5milefinal]

interesting

[Bushav8er]

Just talked with another Esso supplier.

Revised story is:

PRIST will no longer be shipped with fuel from refinery. The phase in will be over 2 years as the trucks are converted with a unit to allow PRIST to be added to the hose during aircraft fueling (not into trucks bulk load). PRIST will have to be requested. So some dealers will have to use the cans until all the trucks are fitted.

Pretty common to have to request prist in the Caribbean and Central/South America. No big deal to say "top it off with prist".

[linecrew]

This is weird, I thought all trucks had a small saddle tank to add AIA/FSII or "Prist" as required, if required right into the hose as the aircraft were being fueled. How were they doing it before? The old can on the wing squirting it in manually trick??

[FL050]

They have been pre-blending it during the truck filling process This is bad because prist is heavier than Jet fuel and the prist will pump out in higher concentrations for the first few fuellings than the last. They will now inject it by request in the perfect 1 part per 1000 formula using a separate tank and injector unit like everyone else has has all along

[AEROMONKEY]

I know that all of the Trucks in YQT have an injector system(esso)...they have had this for sometime now. Are they talking about JETB? They haven't sold that around here in years.

[AEROMONKEY]

They(esso) haven't been injecting it directly into the trucks here in YQT for years now......they have an external tank injection system that is monitored every time an aircraft is fuelled.

[FL050]

They are talking about JetA and JetA1. Not all locations do the pre-blend but ALOT do. Most oil companies forbid that process and can't believe it's still done at all.

Thanks for the info Bushav8er
...all I really care about is if its available or not. Dont really want to haul my own around, if I can help it

One less hazardous substance for the ground crew to worry about. kudos to esso. I know Shell has auto prist injectors in all of thier newer trucks

you mean one MORE hazardous substance to haul around right? if it isn't pre-mixed it has to be done at the truck. which means the guy driving the truck has to fill the little tank.

[hazatude]

Pre-mixed has been being phased out for years. Modern injection systems on the refuellers are safer and less likely to cause globbing. Yes globbing is a word.

[L1011]

The way it worked at the Esso dealership I worked at was the FSII was mixed during the truck fuelling process at the farm. The truck was an older one so it would have to be retrofitted in order to mix FSII "on demand." Another benefit to only pumping FSII when it's needed is cost...you are paying for it when it's pre-mixed, whether you want it or not. With a lot of the older trucks until they're retrofitted, this is one of the only ways it can be done.

And of course handling those barrels is a pain in the ass too.

What is PRIST?

[5400AirportRdSouth]

PRIST is a brand-name for a Fuel System Icing Inhibitor ( pretty much does what the name implies ).

Technically, I think its Methyl Carbitol, but most people just call it Prist, additive or FSII.

I've always heard it recommended to be added only at the time of delivery, as it will seperate from the fuel over time. It gets " injected " into the fuel stream when pumping and gets mixed into the fuel pretty good. Used to be, and probably still available, you'd get it in an aerosol / WD40 type can and shoot a stream into your tank while fueling.

From what I hear, its also pretty nasty stuff.

OK. That's kinda what I thought. Thanks.

Health Information12
Eye contact with DEGME may cause slight temporary eye irritation and/or pain disproportionate
to the level of irritation to the eye. Prolonged skin exposure is not likely to cause significant
irritation or result in absorption of harmful amounts.
No adverse effects are anticipated from single exposure to DEGME vapor. Small amounts
swallowed incidentally as a result of normal handling operations are not likely to cause injury due
to its low toxicity.
Repeated exposure to DEGME in animals has been reported to produce effects in the liver and
kidney and, only after very high oral doses, in the testes and thymus.
Studies in laboratory animals indicate that DEGME is slightly toxic to the fetus at doses nontoxic
to the mother following skin contact. Birth defects have been seen only following high oral doses
which have little relevance to human exposure.
Animal genetic toxicity studies were negative.

From their website...

How do you ensure the product is applied properly?
PRIST® Hi-Flash™ Fuel Additive must be added in the aircraft fueling process. It must be injected into a stream of fuel. It must not be “poured” or “splash blended” into a tank of fuel.

The most common place that PRIST® Hi-Flash™ Fuel Additive is applied is downstream of the final filter/water separator. This ensures that the proper additive concentration is applied at the last point before entering the aircraft that requires the additive for safe flight.

Some fuel suppliers offer “Pre-Blended” fuel which means the additive is injected into the fuel at the time of loading of an over-the-road transport. This is an acceptable way to apply the additive, although caution must be observed to keep the fuel dry at all points downstream in the delivery chain as the additive will accumulate to any water in the fuel system, reducing the additive concentration required by the aircraft

In YKF when I was pumping gas for esso a few years back, we received all our Jet A1 premixed w/ Prist. Had to test it when we received it, to make sure it was in the right concentration and hadn't just attached to any water that may have been present in the tanker. We turned our entire supply of jet over fairly quickly at the time, so apparently it wasn't a major issue.

I know we were one of the few places around here doing this then, and they were already talking about fitting all the trucks with injectors. Since then, it looks like they've acted on that because there are always a few 50 gallon drums sitting around, one of them having a hand pump on the top.

I was always told it was pretty nasty stuff. Daily exposure to 100LL fumes were probably not good for me either, but I was always happy to avoid dealing with prist.

[Oor Wullie]

Pumping JetA1 thorugh a single point isnt really an issue unless of course you blow a coupling.

JetA1 from a nozzle isn't too bad either. Jet fumes are heavier than air, so they just sink over the wing and to the ground. Pumping to quick and getting splash-back should be the major concern! I once witnessed a guy who neglected to put the nozzle past the anti-syphon flap during an overwing fill. He had a shower of jet shoot into his face and 4 feet in the air!. Good thing he's one of those darwin candidates. We may not have to worry about him "spreading the seed." Hopefully the chain stopped there!


Don't get that stuff in your mouth, unless you already have your quota of normal children!
