Welcome to Leader Logic! I'm Amelia, and today I wanted to go through a safety
moment, and I've just picked spiders as an example because it's one that we talk
about a lot here in Australia, and I wanted to use one of the supercharging
techniques that I discussed in my previous video about how
to make the discussion more relevant to designers. So, here we go! And the first
slide just shows an example of all the different spiders that there are in
Australia, I mean there's so many that National Geographic has come out with a
poster of them! Then around the outside of the slide I've actually added
a few particular examples, I can't remember all of the names but, um,
basically the ones on the vertical axis are the ones that are really dangerous
and the ones on the bottom are the ones that will give you a nasty bite but
won't necessarily put you in hospital. No one's actually died recently from a
spider bite, but they can be quite painful. You know, the one that we often
talk about is the red back spider which is the one on the center right hand side.
So yep, spiders are horrifying, they love hiding in nooks and crannies,
they love hiding in, you know, things that you've got leaned up against walls.
Often the safety moments that we have are all about how to prevent being
bitten, so a lot of the things that come up commonly are: being careful, keeping an
eye out, wearing gloves when you're handling equipment, making sure that you
can see where you're putting your hands so don't reach anywhere blindly like
under a ledge. Check under toilet seats, because sometimes you'll get a huntsman
sitting underneath the the toilet seat. I mean, there are a lot of things that come
up on construction sites really regularly, but for designers that's not
necessarily the most relevant thing to be talking about. I think sometimes it's
better to talk about how you might prevent spiders accumulating a
or congregating around the buildings that you're designing. So, first of all,
I've gone through a few other places that they hide, and you know, we'll whip
through those pretty quickly. So: trees and leaf litter, gaps in windows and gaps
around doors. Basically they can crawl through the tiny gaps and get into the
buildings, if you're designing a building or a storage shed or something like that.
They also accumulate around lights, usually because they're trying to build
webs in areas where lots of moths are flying so that they can eat the moths.
They also go up in high corners for the same reason, and basically anywhere where
bugs are congregating. They also like hiding behind anything that's stuck to a
wall or stacked up against a wall, so when I say stuck to a wall I'm thinking
things like air conditioning units, pipelines that are, you know, like down
pipes that are going against a wall. So, those are just the types of places where
you'll genuinely find them, and then also, you know, behind stock piles, behind
things that are on shelves, any stuff that you put down, you set and forget,
they'll tend to find safe habitat in. So, this is the meat of it, which is really
how you can design to prevent spiders finding your design attractive. The
first suggestion is to do with the trees and the shrubs and the leaf litter that
we talked about in the previous slide. Trees are more relevant to the spiders
that live in webs, and leaf litter is more relevant to crawling spiders, but in
both cases this first recommendation is really to look at ways that you can
separate those trees, mulch, leaf litter, anything that's going to be collecting
and providing a safe habitat for spiders, how to keep that a reasonable distance
away from the building so that you're kind of creating a no-man's land where a
crawling spider would have to be very exposed and out in the open to go from
that safe zone to the building that you're designing.
That's even before he manages to find a way into the building. And for tree
spiders, so webbing spiders, having that distance between the tree and the
building makes it a longer distance for their web to span so they're less likely
to be able to either build or maintain our web in that area. The reason why
the webbing spiders are important to reduce is because otherwise you're
just creating an operational or a cleaning cost to remove those webs. If
you can prevent the webs from going up in the first place, then you don't have
to clean them on an ongoing basis. Okay, so the next one is to specify vermin
proofing in your design. So for spiders we're talking about a fine mesh like a
flyscreen on the window if that's appropriate. Now encouraging predators!
You might think, 'well, how can a designer actually encourage predators for spiders?'
Well, what you could do is when you're scoping up a project, you can talk to,
you know, environmental scientists or ecologists and figure out what you can
do in the surrounding landscape to attract predators. So for example in the
case of spiders, birds eat a lot of spiders, and so what you could do is put
nesting boxes for local bird species in the area so that they're attracted to
the area and therefore more likely to encounter the spiders that you're trying
to avoid. And the second one was to encourage competitors. I've got a few
examples here, so apparently ladybugs are quite good competitors for some spider
species because ladybugs are actually carnivorous and eat little aphids. I've
put some geckos there as well because geckos, particularly in
Australia, like to eat the moths that accumulate around lights. If
you're having a problem with spiders because you're getting a lot of moths
accumulating, encouraging geckos to the area might actually be a way of
controlling the moth numbers and therefore keeping the
the spider population down. In that case we're kind of hoping that the
geckos will out-compete the spiders. Now, how you actually create a gecko friendly
environment, I'm not entirely sure. It could be as simple as telling people not to
kill the geckos. But there you go, some ideas to think about on how to prevent
spiders. I've got a few more here, so, one is to prevent the accumulation of
equipment outside in areas where spiders can find shelter. Actually bring the
equipment inside and put it in a very orderly fashion where it's just not
creating that that safe space (for spiders). Again from a designer's perspective your
responsibility would be to actually identify roughly how much equipment
needs to be stored and making sure that if you're designing storage you're
designing enough area to house all of that equipment. The next one is to
automate outdoor lights. So this is touching on the idea of lights
attracting moths and the moths being a food source for the spider. What you
could do is look at whether you really need the night the lights on as much as
they are at other places where you have these types of problems. Do they need
to be on all night, or do they just need to come on when someone's in the area,
would a motion sensor significantly reduce the amount of moths in the area
because the lights are only on for 10 minutes and in that space of time it
doesn't really attract that many months? The other related idea is to look at
whether the bulbs that you're using could be changed out with something
that's less attractive to moths. I am by no means a lighting designer, but it
looks like there are some product out there that create a yellow light and
that attracts fewer moths than a bright white light, so again things to look into,
things to talk to the relevant experts about, but they'll all cut down either
the food source for spiders or the hiding places just
so that they're not such a problem in your future designs. That's it for this
episode, Comment if you think I've missed
anything, and also I'd be interested to hear if you'd like to hear thoughts on
any other safety moment and how that might apply to designers. Like this video,
