    Question Nfpa 1962

    NFPA 1962 7.6.2.13.1 states that if inspecting personnel walk the fire hose test layout to inspect for leaks they should be at least 15 feet away from the left side of the hose. 7.6.2.13.2 states they should never be on the right side of the hose. Left vs. right . . . dont' understand the difference. Why does it specify only walk the left side but stay away from the right?

    A Safety precaution.

    If the hose is going to burst or twist, usually it will be torward the right of the lay out.

    In any case one should always be very careful of any charged hose line be it at a job or being tested.

    Never straddle any hose what is charged or about to become charged!

    Get out of town...

    Are you pulling my leg?

    Is it like a toilet flushes clockwise in the northern hemisphere and counter-clockwise in the southern hemisphere? Would hose bust to the left in Australia? Or is it right handed threaded couplings? Would left handed couplings bust to the left?

    No, seriously, you are putting us on... right?

    7.6.2.13.1 If the inspecting personnel walk the test layout to inspect for leaks, they shall be at least 15 ft (4.5 m) to the left side of the nearest hose line in the test layout. The left side of the hose line shall be defined as that side that is to the left when facing the free end from the pressure source.
    7.6.2.13.2 Personnel shall never stand in front of the free end of the hose, on the right side of the hose, or closer than 15 ft (4.5 m) on the left side of the hose, or straddle a hose in the test layout during the test.

    While I've never heard of this before, one must assume it has something to do with the way they laid canvas hose with a natural twist, leading to a higher probability of a failure propelling the line to the right? New one by me, can't say as I'm convinced this isn't more firehouse lore somehow showing up in later versions of NFPA standards.

    If the hose disconnects from the pump side counter clockwise, the hose will rotate, advancing its power under pressure, and still turning. Thus going to the right.

    BTW which side is the right side? I mean which side is the left side? When you're facing away from the pump or toward it? I need to know this to ensure the safety of our people!

    I'm glad that this problem has been address. I'm sure that who ever looked into this industry sweeping problem was well compensated for their hard work. Money well spent I say. Way to go NFPA!

    but at least it's a national standard.

    Sounds like on a slow day layout some hose. Pressure it

    Then somehow open it up and see which way it sips and how far!!!!

    Fire hose is specifically designed to fail on the warp (length) yarn as opposed to the twist (circumference) so the end of the hose doesnt become a missle. The warp has a twist in it, that caused it to move to the left when facing the free end. I wouldnt worry about what side to be on under working pressure, but testing pressure is a different story.

    It's about the "warp" of the thread used in the woven jacket. As the hose is pressurized and the jacket stretches you can actually observe the clockwise rotation (in the Northern Hemisphere, don't know about down under). It also is the reason why hose that was only hand tightened may need spanner wrenches to uncouple it. Flowing water also rotates in this direction and is the reason why personnel should stay to the left of the hose for safety. NOTE: The directions, left & right, are relative to the firefighter's position facing the nozzle end of the hose.

    after you bring your hose up to test pressure , gate the discharge down to almost closed. If a hose ruptures it wont have much "kick" -

    We close the discharges completely.

    Soo every coupling is 100% not leaking ? Leaving the discharge slightly open will compensate for a slight leakage and maintain true pressure.
