Yep, its a traditional straight edged triangle, not the bulging triangle as in the aero prop logo.
Yup, that's one of the prop AMO decals-Pacific airmotive? Can't remember. Thats on the square tip hollow steel Aeroproducts prop. T I had to do some head scarching, but P-3's only use the round tip solid aluminium Hamiltons. The triangular decal is from the over haul shop, some times the aeroproducts style,sometime the Hamstand stlye.

Last year I attended a laser safety course and got an extensive brief on the ISO Standard warning sign system.
Her is my case for it being an ISO standard warning decal and not a company logo (The ISO warning sign system is now the standard for most parts of the world). The ISO warning triangle is a triangle with a yellow center with a black border with yellow outer edge. There should be a pictorial "multi language" symbol showing the danger painted in black/or contrasting Yellow/black (on the decal in question you can clearly see a propeller symbol on the top part of the triangle, this is per ISO standard) The same color coding goes for the following warning text which has the same border coloring.
From what I can see the mystery decal follows all the above regulations which makes it highly likely it is an ISO warning sign.
This is the ISO warning sign found on the PEQ-2A IR aiming module used on military small arms to show how the symbology with the danger symbol and text (due to lack og space, the iso warning decal has been broken down to 2 separate part with symbol and text)

Adrian, that is a figgen nice photo, so cool thing we have found it depends on services the aircraft/propellers - S.A.F.E Air NZ simply places there logo even , I guess replace the ISO sticker for their quality insurance on work done .no its unfortunately not that decal,...it is this one...even though its on a Convair580 it is looking at the P-3 photos the same decal...
Yes, Jens, that is an ISO laser warning tag, and those are found around laser emitters. However, in my 35 plus years of watching the autopilot at work and fixing the darn things I can state with certainty that warning decals like the red/white triangle you are thinking of are a standard warning for explosive or cartridge actuated devices- ejector seats, MDC canopy breakers and ejector racks. Prop warnings are painted tips and the prop arc marks on the aircraft hull. The decal on the prop blades are mfg's or overhaul shop's decals. Trust me on that. Still looking for a good scan of the specific decal, but you could use the hamilton standard decal and not be wrong.

I know very well the old danger and warning signs used on propeller aircraft. ISO signs are not only for lasers, but for any hazard and it is the new global standard for such decals. The new signs are something which have suddenly appeared on P-3 propellers, even here in Norway on the C/N fleet.
Just look at the pics, the black and yellow triangle perfectly follow the ISO standard with a stylized 3 bladed propeller as the danger symbol followd by the warning text bellow. The triangle is pointed in the direction the propeller is turning.
On the normal/ older P-3 blades it was common to see the badge of the manufacturer, but not anymore.
I know of norwegian military equipment which have been grounded because the dangerous/ optical sights with lasers part did not have the new ISO warning sign ( only older US warning signs), so this is definetly a trend coming.

Im no aircraft engineer for sure 
Hopefully we will soon have some hard facts about it. GE is asking the USN and i have asked en engineer and a few pilots from 333 sqn here in Norway.
Due to some miscommunication from my side to KBT, it was the beta of the P -3B he uploaded. Hopefully we will have the final package ready.

I just got an answer from a Captain which is a flight engineer at 333 Skv in Norway and he confirms he has seen ISO warning labels on newer props with the 3 bladed propeller symbol at the top. He also said it was a bit of a lottery what kind of decals the blades have when they get them to Norway. Beside that Norway paints the tips yellow, they are of course sourced from the same supplier as the USN. So it might look like there are differences from batch to batch etc. Might also be with ISO certification for the manufacturer/overhauling company. Can be interesting to hear if the USN actually have specified ISO warning labels on the blades or not.
The answers from the pilots of course were that they had not seen any decals at all on the props during their walk around...hehe

Very interesting info Jens.
I never did hear from anyone at VP-10, I can go tomorrow to the Navy Base that is about 10 miles from here and talk to the Enlisted Aviation Detailers or the Aviation Officer Assignments (Pilots)
and ask them. I will take some photos of what you posted here and get them to comment on them and perhaps give me enough info to crack this nut.
IMHO, I think that some of those decals are applied (Tagged) to the blades once they have been overhauled and it should show the activity (logo) of the activity that did the overhaul.
Back before NADEP there was NARF (NAVAL AIR REPAIR FACILITY) and they were located in either Jacksonville FL Nofolk VA or North Island CA. They all had a triangular logos that
had the name of the overhaul facility within the triangle logo design.
BTW, BZ to you and all that did the P-3B, great job!
I found it cleaver that the pod light goes away when it is turned of and doesn't remain under the wing in the off setting. But hey it's all good.
Those decals on the P-3 Blades have really piqued my curiosity.

Ansi iso labels
Here are some examples of some of the ANSI ISO pictograms
not sure which one would go on a propeller.

Here is close up of a USAF C-130 Herc prop and the label is really showing the detail. Too bad it was not of the P-3.
But here is something to ponder. Wouldn't those ANSI ISO standard apply to all Branches of the US Service instead of just the US NAVY.
Reason I brought that up was I wanted to see if the C-130 prop blade had those safety decals on them, so far, haven't seen any, here is
one of a USAF C-130
I am not trying to compare apples to oranges, just thought that maybe that safety sticker would of been plastered on ALL propeller regardless of branch of service. A safety hazard is a safety
hazard I would think.
Edit: I check for the USMC Fat Albert hoping that maybe I'd get lucky and find a good close up of one of their prop's: no dice. Oh well.

Sure is a bit amazing to see that it looks to be no guidelines on what kind of warning decals they are putting on the props at all. The US military tend to be good at that part.. For a comparison, I don't think I have seen anything similar to the ISO label on any new C-130J, so it looks to be a "issue" seen on P-3s and a few other propeller aircraft.
This could maybe point in the direction that these ISO stickers have been put on the blade by the manufacturer or overhaul company in accordance with their own ISO safety certification regs.

The Aero Union P-3s have the traditional prop markings, so no, no help. These are new markings, and I'm siding with them being the "safety" triangles.

The triangular logo on the props is the Overhaul Decal from Pacific Propeller Inc.
You can see it at:

Video #3 at 2:30 mark.
PPI had the overhaul contract for P-3s for many years. They did an excellent job for "relatively" cheap.
If the prop is completely rebuilt by Hamilton Standard it gets the Oval Decal.
Sometimes FRCs stick on their decal when the I level propshop works on it.

Yes he has! We are starting to have a rather extensive collection of orions!
Very interesting info indeed! Thanks for sharing. I checked with 333skv again and it might be that it was perceived as an iso badge as it is very very similar with the same layout, colors and borders.
The final textures for the P-3B were sent to KBT last night and hopefully the entire package should be ready for download soon.
