<p class="p1">I am the PhD student who made the blackboard possible. I fully agree with Alfonso’s points. I will try to establish a regular cleaning cycle for the erasers (which can be washed) to help reduce the spread of chalk dust. If she’s comfortable, I
may also ask Margaret to clean them weekly. <o:p></o:p></p>
<p class="p1">Perhaps we could also post a brief “housekeeping” note near the board for visitors, so they know to keep the chalk and erasers off tables and chairs.<o:p></o:p></p>
<p class="p1">I understand the concerns around chalk dust—particularly for those with respiratory sensitivities—but blackboards do come with the territory of a bit of mess. While I appreciate the reminder to be mindful, the idea that chalk dust is ruining clothes
might be an overreach: if you’re working with or around a chalkboard, some dust exposure is almost inevitable.

<p class="MsoNormal"><span style="font-size:11.0pt"> <o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">If you use the blackboard in A113, please try to minimise the amount of dust generated (I know the chalk is classed as “dust-free”, but it still produces significant amounts of dust). Dust not only creates
additional work for our cleaner, but it may be harmful for people with respiratory problems such as asthma. It is also difficult to remove from clothes.

<p class="MsoNormal"><span style="font-size:11.0pt"> <o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">If you use the blackboard, it is important that:<o:p></o:p></span></p>

<p class="MsoListParagraph" style="text-indent:-18.0pt"><span style="font-size:11.0pt">The erasers are cleaned (outdoors, at the back of the building) regularly, to reduce the chalk dust they accumulate. If you use the blackboard, please clean the erasers.
Users may consider a “rota” to ensure this happens a few times per week. <o:p></o:p></span></p>

<p class="MsoListParagraph" style="text-indent:-18.0pt"><span style="font-size:11.0pt">Chalk and erasers are placed in the box provided during and after use, and NOT on the tables/desks/chairs. People who attend seminars in that room do not want to get their
clothes ruined by chalk dust. And our cleaner doesn’t need extra dusting. <o:p></o:p></span></p>
