All true. It also tastes bad and makes your lips numb.

But think of it this way, there are a lot of things that we drink for fun that would also fit that description! Cool

anybody want to bet that That_Engine_guy is QA

Good ways to stay warm:

Strech out those eng runs/leak and Xfers/ anything with ECS.
Dress in layers till you can't move anymore.
Be a nonner and always volunteer to do Cams/order parts.

Or you could wimp out and call for a heater(I have)

Nope, I'm not QA; just an Engine Troop for 17+ years. Thumb

(Back in the day of good ol' JP-4)

I would be more worried about the exhaust fumes, rather than anything the engine or JFS 'may' spit out due to failure or fire.

I do read the MSDSs whenever I get the chance. Makes for some interesting reading. I would just like to use SOME of my retirement, so I do try to stay as safe as possible. There seems to be a strong pattern of people who retire after many years of aircraft maintenance that only see a few retirement checks before they can't cash them anymore... Crying or Very sad

Side note - We use "Milk of Magnesia" for some F100 assembly processes and are required to keep an MSDS for it because it is in our "Hazardous Materials" locker. Makes sense, right!? Rolling Eyes

Have you ever read the MSDS for windex? At Eglin, someone in supervision with too much time on their hands (lot of that there) did, and the next thing you know....we're wearing gloves and a face shield to clean the windows. No kidding.

I like to find all of the 10JG's I can find and have a little hamburger roast out on the line. 52 and 53JG's work well for this purpose also. QA tends to frown on this practice (haven't figured out why yet) and you need a good story for support when you go to turn in your box. Also causes a shortage of 10's from time to time.

Absolutely rubbish … (Bullshit) … I’ve launched and winched jets in and out of 1st to 3rd generation shelters overseas for over ten years. If your going to get excessive fumes it will be from inside the shelter. Fumes were so bad at times my eyes watered. I did 23 years active duty as a Crew Dawg and have been retired for 4 years now and still fill the sleeves of my Gortex jacket with genuine Pratt exhaust gasses as a civilian dawg. When I’m cold the JFS warms my feet and lower extremity well.

Hydraulic fluid, engine oil, B half sealant, Fuel, and other sh*t continues to touch my skin even though PPE is worn. A’m I worried … NO… Life goes on.

Here is the MSDS for JP-8 http://www.hess.com/ehs/msds/JP8_HOV_4088_clr.pdf it has no benzene so you should be ok. according to this the carcinogenic properties aren't that servere, everyone should be ok. as far as the +100 additive, there is no way that the MSDS could be kept a "trade secret" from people on the line. We use it here at Luke and I could prolly find the MSDS on it at work tonight. Any and all chemicals encountered by personnel have to have an MSDS somewhere in the AMU, it's illegal to hide this information from personnel per AFI....if it IS being withheld, then someone from a safety agency or way up the chain needs to know about it....what if you come in contact with it? how are they going to know how treat you if it is a "trade secret" and nobody can get ahold of an MSDS? that sounds like a bunch of B.S. to me....just found this on +100 enjoy http://msds.ogden.disa.mil/msds/owa/web ... snr=188384

Not that the MSDS is a trade secret but look at it...

Ingredient #............................ 01
Ingredient Name......................... SOLVENT NAPHTHA PETROLEUM HEAVY AROMATIC
CAS Number.............................. 64742945
Percent................................. 0
Ingredient #............................ 02
Ingredient Name......................... TRADE SECRET 561
Percent................................. 0
Ingredient #............................ 03
Ingredient Name......................... TRADE SECRET 428
Percent................................. 0
Ingredient #............................ 04
Ingredient Name......................... NAPHTHALENE (6-10%)
CAS Number.............................. 91203
Percent................................. 10

So what's in it? If it's only 10% Naphthalene what's the other 90%?

If you DO have a reaction and you do take the MSDS to a doctor or medic, how they going to treat you? Why does the DOD allow stuff like this? WTF

Why do you think they have you sign paperwork yearly that states you know your hazards and use your PPE? So they can deny your VA claim if you ever have complications. Read a little between the lines. Our government use to spray entire states with DDT to control pests, sure it was safe.... at the time, right?

I'm not paranoid about con-trail fall out, or UFOs, but when it comes to nameless chemicals being used on a daily basis, I get a little leery... Shocked

We always launched from inside the HAS during wintertime when on base at Bodø. We had offcorse warm clothes and gloves but, nothing more than that. And offcorse we hurried back into the "bar" when the jet left.

But I have recovered during exersise, mid winter in Finnmark, Northen Norway (type in ICAO code ENNA and you'l see the AP is located at about 70" North.). That was not very plesant, temprature at -35C and a nice breeze made an effective temprature at about -50C.. that was C O L D to say the least.

Yup, that is Cold Shocked

For us, now is the time of the season when we have to jump the intakes and it’s 100F plus outside with a tail wind blowing through the core of the motor.

I will measure it one day … its got to be pushing 150F in there. Shocked

I would agree; I've been in tubes as well during a nice hot/humid 120*F Kuwaiti summer day, 150*F+ easy in the inlet! Shocked

I'm sure V2 (and his tube diving buddies) are using a second person as a safety observer, "Technician B", to ensure "Technician A," who is down that 150*F tube does not succumb to the heat...

I bet they trade off A/B - B/A - A/B as they move down the line... (That is if they're using a dedicated "tube team" engine inlet/exhaust inspection concept)

Right?

Keep 'em flyin, safely... Thumb

Oh you wimps try it with JP-4 in the J-79, nice and toasty with just a hint of burned oil on your
green jeans.
The black sooty coating you got helped keep the cold off you skin too.
Devil

Aside from all the nasty stuff you find in JP-8, there was always that possibility of something comming out the a$$ end and hitting you. For example, if a compressor blade let go, it's gonna take out a few more along the way and guess where it's heading? Any one up for target practice? lol

Kinda stretching it, but hey, backshop does forget things. That was one of the reasons QA would bust you. Just my Two Cents

. What's up TEG.

Hey Mush...

I wouldn't worry about blades too much, if they're going to let loose they typically go out on the 'cell.

What I WOULD worry about are those tiny bits and pieces of honeycomb blade outer air seals (BOAS) and small bits of abraidable material from the engine being ejected at high-speed. (Even at idle that exhaust is fast!)

Anyone heard of "Core Run-In"? They're done for a reason, and the Anti-Ice valve isn't removed for GPs or safety-wire practice.

BOAS/abraidables are designed and built to wear and/or shed material as turbine or compressor blades stretch. Catch an 1/16 inch square piece of honeycomb from a High Pressure Turbine in your hand and I'm certain you'll know it! Shocked

You can also see the occasional spark fly from the JSF at night too. Don't try to catch them, they're not fire-flys... Laughing

Not sure what would hurt more; digging said object from your hand/arm with forceps at the flight-surgeon's office, or explaining Wing Safety/QA how it got there?
