  •   This type of simulation was very beneficial to the ERT members as

    it gave them a first hand knowledge of what to expect in an actual

    situation.

      Think safety...

  •   Within a few minutes, the fire was put off, and the building

    was no longer in danger.

      Fortunately, this was not a real fire. It was just a simulation,

    using real LPG gas and burning in a controlled manner. This was

    done to give the ERT members some feel of the real thing, to

    check on our readiness, coordination, and skills so that they

    can improve and develop their actions.

  •   There were sufficient people to operate 3 hose teams. While one

    team approach the flaming area with a water-wall spray, another

    two teams directed the water to the top of the LPG tanks with

    water jet for cooling.

      After a while, it was discovered that there was a casualty.

    Somebody has been overcome by the smoke and has fainted. He has

    also sustained a fracture on his arm. The first aid team was

    called in, and they rendered first aid to the victim.

  •   The LPG fire need to be extinguished - but not by the water.

    Extinguishing the fire in this way will create another hazard.

    If the gas were to escape unburned, it could be more dangerous.

    Any spark later on can ignite the gas and cause a bigger fire,

    possibly causing a tremendous rush of expanding gases. So the

    hose team have to try to approach the fire in order to close the

    gas valve. That will stop the fire and the escaping gas.

  •   As the ERT members reached the scene of the fire, the Commander

    directed the operations while keeping in touch with one member

    who was assigned for communications work at the command post.

      The Direct Attack Team swung into action with their hoses. There

    were 4 persons in each hose team - the first nozzle member, the

    second support, the third runner, and the fourth hydrant valve

    operator. Each member played their part to make the hose

    connections, operate the valves, and advancing as smoothly as

    possible.

  •   The motor and the driven machine should be bolted solidly to thebase after finalizing the alignment positions of the equipment.

  •   Angular alignment

      By inserting a feeler gauge between the coupling faces androtate both coupling halves simultaneously we can check whetherthe shafts have any angular displacement between them. Thefeeler gauge readings at checked at four points on the shaftcoupling. Again the alignment is corrected by shimming orshifting the machinery.

  •   Offset Alignment

      The radial alignment is checked using a straight edge ruler. Byplacing the ruler across the coupling halves at the top, bottomand both sides any gaps between the 2 coupling halves willindicate that the shaft is offset slightly. The misalignment canbe corrected by shifting the motor or by putting shims to raiseup the motor or driven machine.

  •   Provided the two shafts are not bent crooked, the two alignmentsto be checked and adjusted are: Offset alignment and Angularalignment.

      Most alignments are rough alignment that can be done usingstraight edge ruler and feeler gages. However for precisionalignment, the use of dial gauges with magnetic bases can beused.
