    On a tractor forum in a chainsaw section I saw a report that Osha has banned Stihl saws due to fuel geysers when hot due to the 'flippy caps'. Seems opening them rapidly can cause fuel blow out on the operator and has resulted in bad burns.

    I doesn't sound right to me. If true it wouild have been published and been discussed all over the 'net'

    Am I missing something...how is this a cap problem?

    Looks more like a malfunctioning vent.

    There is no question about it happening, it is even discussed in the saw manual and how to prevent it. You just have to remember not to open the cap quickly.

    Sprayed with fuel, hot saw...wonder just what could go wrong. Yes, I have had fuel spray, not that bad tho and there was nothing wrong with how the saw ran.

    It appears from this thread that there is no such thing a Osha banning them...at least no one seems to have heard about it.

    Google turns up nothing on OSHA banning them.

    Nay kee mo sabe, works as intended.

    Vent is to let air IN to replace volume of spent fuel. Not to let vapor or liquid excape.

    Google also turns up nothing about POTUS #42, rides on private jets, and young girls on a Caribbean island (that's a topic for a different thread in a different subforum, but you get the idea).

    If it were the older screw cap, it still would have shot out - but maybe more down towards the saw, not up. Never had this happen on my three flippy cap models.

    The screw cap realeases the pressure gradually as you unscrew it. By the time it is out far enough to remove the excess pressure is gone. Back in the early 80s I had an old saw where the fuel would boil, never had any spray me.

    Fuel geysering is a point of focus with the wildland fire community. They often work at varying altitudes (mountains) and rapidly changing temperatures (fires). So there has been some USFS and BLM stuff posted on the topic. OSHA would not ban a specific brand of saw - they might post an advisory on it. As noted, fuel can also geyser with screw caps.

    I agree that the screw cap releases more gradually but f there was the same pressure that was in the video, as soon as the cap seal was released I think at least some gas would shoot out - just not straight out at the operator.
