<p>The household shelter consists of:</p>
<ul>
    <li>Door<br />
    The door is designed to protect you against the blasting effect of weapons during an emergency. It also provides an air-tight closure to the shelter.</li>
    <li>Rubber gasket at the door and ventilation sleeve<br />
    The rubber gasket serves to provide an air-tight environment to the shelter and prevent seepage of toxic gases during an emergency.</li>
    <li>Door handle<br />
    The door handle has a dual purpose. During peacetime, the handle is swung downwards to open the door. In an emergency situation, the handle is lifted and swung upwards in Civil Defence mode to ensure that the shelter is air-tight.</li>
    <li>Ventilation sleeve<br />
    During peace time, the fragmentation plate is held in open position by 4 M8 stainless steel screws connected to the ventilation sleeve. In an emergency, the plate is tightened using the 4 screws against the sleeve and compressing the &lsquo;O&rsquo; ring rubber gasket to provide an air-tight shelter. Regular checks are necessary to ensure that the &lsquo;O&rsquo; ring rubber gasket is intact and the screws are oiled to facilitate easy tightening during an emergency.</li>
</ul>

Components

<h3>The door cannot be opened or closed properly</h3>
<p>The door may not open or close properly, causing scratch marks on the door frame.</p>

<ul>
    <li>Why it happens:

    </li>
    <li>Solutions:
    <ul>
        <li>Tighten the loosened screws</li>

<ul>
    <li>Why this happens:
    <ul>
        <li>Connecting screws in the lockset (the hardware making up the locking mechanism) may have dropped off or loosened, causing the latch to jam</li>
        <li>Mechanical parts inside the lockset may be damaged or worn out</li>
        <li>Rust could have formed on the parts inside the lockset because of moisture entering during regular cleaning of the door</li>
    </ul>
    </li>
    <li>Solutions:
    <ul>
        <li>Spray oil lubricant onto the latch and press the door handle downwards</li>

        <li>Ensure that no water gets into the lockset when cleaning the door with a wet cloth. After cleaning the door, wipe the damp area with a dry cloth</li>
    </ul>
    </li>
</ul>
<h3>Rubber gasket loosens and dangles from the ventilation sleeve</h3>
<p>The &lsquo;O&rsquo; ring rubber gasket is sealed to the rim of the sleeve by adhesives to ensure air-tightness when the plate is tightened against the sleeve during an emergency.</p>
<p style="text-align: center;"><img src="/-/media/managing-my-home/renovation-and-maintenance/home-maintenance/home-care-guide/household-shelter/oring.jpg" alt="o-ring" /></p>
