<div>Please be <b>very careful</b> in making sure that you have
an NHS trust who is completely willing to accept what you're
making (and the way you're making it). There's a lot to
consider here: are the materials you're using appropriate for
a medical environment? if you were to be infected would you be
passing that along into your supply chain? The <a

moz-do-not-send="true">guidance from Prusa</a> isn't all
encompassing, but a couple of things they have listed are:</div>

</div>
<div>
<ul>
<li>Using a fresh set of gloves for collecting each batch of
prints</li>
<li>Immediately placing parts into a seal-able bag</li>

<p>A <b>brilliant</b> point!!<br>

<p>First of all there has to be a way of cleaning these before use.
Sodium hypochlorite the main ingredient in bleach will kill this
virus, but it can survive on plastic surfaces for a while. It is
actually a virus with RNA at the core rather than DNA and this
makes it poorer at surviving outside a host.<br>
</p>
<p> Without burdening you with links there is a good deal of
research out there that shows that between about 30-60% of people
will get the virus and not have any symptoms at all. We don't have
the clean environment that the factories making this stuff would
normally have and the hospitals would have to assume that proper
steps on cleanliness would <b>not</b> have been taken.<br>
</p>
<p>Secondly can someone with proper information please get hold of
an assurance that people are not going to be wasting their time.
We need proper evidence from an NHS trust somewhere. A proper <b>written
assurance</b> is needed! Let's make sure that this isn't
someone's idea that is just spreading virally and where actually
the stuff has to be binned.</p>
