A friend of mine his dad works in the air force as in a fire department. He told me once that if you see an F-16 crash, just run away from it because the hydrazine tanks could open and if you inhale this hydrazine,you are a lot more likely to get cancer on a later date. Confused

Just stay back and up-wind......... Wink

You wouldn't want to be hit by a stray 20mm round or a chaff/flare cartridge either.

Did any of you saw f-16 crash? (I did)
One thing is certain - the hydrazine container survives
it's built of some stainless alloy very strong.

The H-70 reacts to alluminium, water and air therefore when H-70 come with these matirials it's expands thats why it is used in the world of aviation. (In space Hydrazine used to turn the shuttle nose right/left)
It's not safe you'll probably need medical treatment (Blood Check for sure) after you exposed. the main problem is long effect - lung, liver you name it.
I saw people that work with each day exposed and believe me they all right.

When EPU starts you need to speed the Turbine to 75K in no time cause
you need electricity since the main gen and stdby gen are down. The H-70
Mode is initiated first and the Turbine turns to 75K in a matter of mSecs.

The container may survive, but what about the connections?

Self sealing. If a line breaks the connections close off autmatically. Like a race car fuel cell or visa versu. I a viper goes down near you run the other way. Burning carbon, fuel, Hyd Fluid, H70, it all is a mess. These days post 911 ya never know it may have live wpns on board too. Run, Forest Run.

Great info on the EPU... As an F-16 Fuel Sys Instructor, I'm always looking for new ways to explain it to the troops. (thanks Mark, Bix, IDcrewdog, etc.)
True... H-70 is 70% Hydrazine/30% water. Creates a chemical reaction to iridium. Spins a turbine to 75,000 RPM (as we say in Boston, wicked freakin' fast!). Powers an electric motor and a hydraulic motor (not sure which system, but I'd hope both to some extent (don't they bleed together a little?)). Exhaust is steam, ammonia, hydrogen and nitrogen at up to 1600 degress F.
Flase... If you smell it you are dead. Just smelling it is considered "overexposure"; more than is considered safe. Having been "exposed" many times, I'm living proof. I didn't enjoy the endless pricks (from the needles) to get my blood tested, but Hydrazine collects in the liver (and other organs) and doesn't ever go away. Other toxins (like benzyne in JP-4/5/ Cool

collect as well, but get excreted over time.
I've been a first responder to many crashes and seen the H-70 tank in different states, from still in the jet, to pieces.
If you are still interested in pics, I can get you some from the trainer we use in class. Sort of a full mock-up of the jet.

Yes I am still interested in pics, at the moment I am working on the PowerPointPresentation on F 16 crashes.
The presentation is for "urban firefigthers", but we have a F 16 airbase in the region.
I am interested in pics of the H-70 itself.

Rodney, We at eh 20 FW did a presentation to local first responders. It went over all the hazards y'all may encounter. Email/PM me and I will send you the PP slide show that we presented too them. Make sure the address is a good one because it is a big file.

Rodney,

Found this one in our archives.

Photo is Belgian AF F-16 during an airshow at Florennes AB and can also be found at

PM me if you need a really high-res version.

Thanks, I found this one myself.

Is it true that H-70 spills can be neutralized with a mixture of water and bleach?

The orange dot, left of the exhaust, is it an indicator for H-70 leaks?
If so, wich colour does it show when H-70 is leaking?

Dark purple to black.

Did you get the PPoint I sent you?

PPP is OK, thanks.
Do you know about the bleach and water?
Is there an other dot on the plane that marks H-70 leaks ore use of H-70?
I heard about two places where you could see a spil ore use of EPU?

Use, well there is the fired (used) indicator on the right side of the intake but it does not indicate a leak, just the indicator mentioned ealier does this. Yes, Bleach and water. I don't know the mix though. Maybe a fuels troop can chime in on that one. Check the "name this part" thread on page 4 there is a shot of it.

It would be 100 gals/bleach to 1 gallon of water will neutralize 1 gallon of H-70. NEVER add straight bleach to H-70. Always dilute it with water first then the bleach. You can also use HTH, but I have never used it. Does it take 100 gallons of bleach to neutralize it, no. I've used about 1/2 of that and it worked great...
