Running the #happiest5k

Posted on Updated on

The Newcastle Colour Run was on yesterday, and once again it was great fun morning, albeit a bit dusty! A very big thank you goes to the five volunteers who graciously wore personal exposure monitors for the entire run as part of an exposure assessment.

It was a little awkward running with a pump on your bum, but it was in the name of science!

We managed to collect 5 valid personal exposure samples for inhalable dust (one sample was invalid ahh!). All the samples have gone in for analysis, so now the waiting game begins. We certainly had some colourful sample filters, all in varying shades and varying amounts of dustiness. It will be interesting to see what the results say…so check back here in a few weeks and I’ll let you know!

I also found another good use for the GoPro, so for those of you who have never seen a Colour Run before – check this out so you can see what it’s all about!

    How will you discern whether the filter received a direct hit or actually sampled inhalable particulate?
    You could also calculate what concentration you would need to have over the couple of minutes of exposure to be of concern…a real time logger (ie dustrak) may be beneficial in this type of circumstance as its a short high exposure….thoughts?

    Jane you are always one step ahead of me – Kristy and I were just discussing this! As is turns out, when the filter was placed into the lab-supplied filter holder, the “direct hit” globules (as shown in the photo) actually fell off the sample filter. It’s definitely a limitation to the approach, but I’m not sure how to address this in the future. Suggestions? We did consider using a dustrack, but the only issue was the weight of the unit, my poor fitness, and the fact that it was 5km’s. I need to find a smaller alternative!

      I would have used a dust trak to get an indication of the levels at the finish line (over time), and then calculated potential worst case exposure based on the time an individual would have been exposed…of course, that is fine for the non senstive, healthy worker 🙂

    My 12 year old daughter wants to do the run in Melbourne this weekend. I am absolutely not in favour of this. Corn flour & Natural food dyes may well be safe when consumed as normal but they are not meant to be inhaled. I work in the food industry and well aware of the dangers of inhaling foods in powder form. I note the figure quoted of 3mg / m3, I can tell you just from looking a the pictures there is more than 3mg of dust, no elaborate scientific testing required to work that out.
