    work in confined space-2



    Pyrophoric materials and disposal

    In oil refineries, the major source of pyrophoric substance is
    the iron sulphide.Pyrophoric iron sulphides are a corrosion product
    that may form on the walls of vessels,tanks, towers, pipes, flare
    headers, etc which contain sulfur compounds.


    You can avoid fire

    When pyrophoric substances come in contact with air they react
    with the oxygen generating heat. If heat is not dissipated, the
    temperature would rise high enough to ignite a flammable mixture.
    So before allowing man entry potassium permanganate solution should
    be used to diffuse pyrophoric iron.Pyrophoric scales and rust
    particles containing iron sulphides shall be kept isolated from
    oxygen by blanketing with inert gas or wet with water until these
    are removed to a safe area or buried to prevent ignition.


    Pyrophoric material should be immediately wetted with water after
    removing from the vessel.




    Confined space - means a space that may or may not be enclosed
    or causes discomfort while working.
    Examples are pits, ditches, vessels, fire water pits, culverts,
    columns, tanks etc.
    Before entering any confined space, you must ensure the following:

    ??Supervisor must explain you the risks identified on work permit in
    local language and the precautions to you before going to work
    inside confined space.




    You should look for proper ventilation and escape route.
    Ensure adequate ventilation of the confined space.





    You should not block ventilation openings.
    You should avoid fall due to slippery surface inside the confined space.
    You should handover your I card to standby person before entering
    confined space.

    Standby person should collect the I cards of the persons entering
    the confined space.






    You should not ask stand by person to carry out any work, as he is there to summon rescue and other emergency services as soon he determines that the entrants need assistance to escape from the confined space.

    You should think of escape route and practice to come out (at least once) before working inside the confined space.

    You should never remove the PPE while working inside the confined space.

    Entry into the confined space should be made only after wearing
    mandatory and special PPEs.





    You should ensure good housekeeping inside the confined space to
    prevent trip & fall. Remove all unwanted material from the confined space.

    Avoid crowding of excess material around the escape route.
    It should be kept clear.






    You should ensure that you have removed all your material from
    the confined space once the job is completed.

    You should come out of the confined space immediately without asking
    any question if asked by the stand by person.

    If you have to evacuate due to emergency, standby person will
    whistle continuously, if he wants to get in contact he will give
    2 short whistles.
